1 Introduction

Figure 1: The Masterpiece HD Mixer

1.1 Overview

Masterpiece is Snell’s High Definition, fully featured, master control mixer. An extensive range of optional features makes Masterpiece a complete channel-branding solution in a single box. Designed for High Definition TV, but also compatible with Standard Definition, Masterpiece is ideal for installations planning a transition from SD to HD, or even upgrading their current HD standard. All video and audio processing is contained in the same 2U frame, with standard features, as follows:

Mix, wipe and fade transitions

Four Down Stream Keyers with full preview facility for HD standards

Embedded audio processing for up to 8 levels of AES

Eight assignable AES audio ‘over’ inputs

Dual PSU with optional relay bypass

Additional features are available as follows:

Two-channel, 3D DVE

Store for a large number of logo images, including animated logos.

Dolby E encoding and decoding – Using external encoders and decoders.

These additional features need both hardware and software configuration. Any Masterpiece mixer can be upgraded on-site, with minimal downtime.

Masterpiece uses the same control panels as the Snell TX500 Master Control range, known as the TX520, TX510, TX502 and the ‘Masterpiece’ PC based soft panel. These panels offer a varying range of features, and sizes, and are well established and familiar to a large customer base, therefore easing the introduction of Masterpiece into existing installations.

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 7

Masterpiece also supports the Snell Audio fader panel, giving the user enhanced control of audio overs, as well as the ability to ‘lead’ and ‘lag’ the audio over a video transition.

Masterpiece fully integrates with Snell’s Morpheus Automation and routing products. Through the serial automation interface, all keying, DVE and audio features can be controlled, including the selection of specific logos and DVE sequences. Any Snell router may be directly connected to Masterpiece for selection of up to 20 sources. If the Snell Aurora router control system is included, any sources from any router in the system can be assigned and routed, including the ability to ‘auto-assign’ sources via the automation.

on the Programme path. Typically, this external signal, labelled as ‘Preview’ on the rear panel, is fed from the Auxiliary output on the router and can therefore be switched by the operator from the TX500 control panel. The Preview output will not function without an external signal connected. The operator can then adjust the DSK Clip and Gain settings against the required background.

Duplicate outputs are available for the Preview, Programme and Clean-feed signals.

Note: The SD variant of Masterpiece does not support the DSK or DVE preview.

Figure 4: The Audio Path Block Diagram

Figure 4 shows the audio path through the Masterpiece mixer. There are up to 8 AES levels of embedded audio (internally extracted from the incoming video signals) or alternatively, up to 4 discrete levels of AES audio. The audio maybe extracted from different video signals than are used for the video path. This is to enable split transitions, such as audio lead and lag, to be used. Additionally, 8 AES audio over inputs are provided, which may be mixed onto the outgoing Programme feeds according the mixer configuration. See section 2.3 for all available configurations.

The Programme audio output is embedded with the Programme video before leaving the mixer.

The clean feed audio output is embedded with the clean feed video before leaving the mixer.

2 System Interconnections

The following diagram (figure 11) shows a typical system with interconnections between the router and the mixer. The router passes video signals with embedded audio, and separate router outputs are connected to the mixer for video and audio mixing, meaning that a minimum of 4 router outputs is required.

The mixer can be considered as 3 components, the video mixer, audio mixer and 2330 Control Card. The video and audio mixers can be controlled externally, from an existing Snell mixer, such as the TX500, in which case the 2330 control card will not be fitted. D-type connectors are supplied on the rear panel for this purpose.

2.1 Router Connection

There are two methods of controlling the video router, known within the system configuration as ‘Local’ and ‘External’ (see section 7.6.1)

Local control requires a direct connection from the mixer ‘router’ RS422 port to the router control port, which must be configured for General Switcher Protocol. This configuration maps the router sources directly to the channel buttons on the mixer

control panel. Router destination numbers are configured within the system configuration accessible through the control panel (see section 0).

External control requires the connection of an Aurora controller, to which the mixer will connect as if it where a control panel, using Multidrop protocol. The Aurora control system will include a Source Assignment panel, which will allow any source under Aurora control, to be assigned to the mixer channel buttons.

Video feeds of the router Programme and Preset outputs must be connected to the mixer. To achieve flexibility, the DSK mixer inputs may also be connected to router outputs, in order that different key sources can be selected using an external control panel. In HD systems, if it is intended to use the mixer DSK Preview function, the Preview input must be connected to a video feed; commonly this is connected to the router output being switched by the Auxiliary buss. Two identical Preview outputs are provided.

Two identical Mixer Clean Feed outputs are also provided, these are copies of the Programme signal after mixing but before any key signals or DVE moves are applied. These are embedded with clean feed audio, which is a copy of Programme audio before any audio overs are added.

Each keyer requires a Key and Fill video signal, unless they are configured for ‘Self Keying’ in to Operator Settings (see section 5.1), in which case only a Fill signal is required.

The internal DVE module can accept a feed of a second foreground, the first foreground is provided internally by any point in the programme path, an input is also provided for a background. The need for these signals depends on the DVE sequence loaded: some sequences do not require a second foreground. DVE sequences are loaded and previewed via the control panel and a separate DVE Preview output is provided on the mixer. An external DVE unit may be connected and controlled by Masterpiece, currently only the Snell & Wilcox Magic Dave is supported; for this purpose, video in and out connections are provided (EXT DVE), as well as a serial control connection (DVE).

The PGM and PST audio inputs to the mixer (labelled PGM+E and PST+E) are video signals with embedded audio; up to 8 AES levels of audio are extracted internally by the mixer, creating 16 mono levels internally, which can be assigned to different mixer transition blocks. These inputs are usually separate to the video inputs so that split transitions and audio break-away can be achieved. However, if these features are not required, and the user has a restricted number of router

outputs available, the audio can be extracted from the same video signals as used for the video mixing. This limits the type of mixer transition possible, and it is recommended that this is not used unless essential.

This configuration requires a change to the HD_MIXER.INI file (see section 3.4). The PGM and PST inputs must be connected to router outputs.

Delay may be manually inserted into selected audio paths using the HD_MIXER.INI file (see section 3.4). This will be required if a DVE has been included in the corresponding video path, for instance. Three AES audio outputs and one AES input are supplied for an external Dolby Encoder; this option is also configured in the HD_MIXER.INI file.

The ‘audio routing’ section of the mixer allows channels to be ‘shuffled’, so that different channels can be routed to different outputs. The first 8 channels (four levels) can be shuffled through the Operator configuration screen on the control panel (see section 5.1).

The audio mixer section performs the mix/wipe/fade transition between PGM and PST, followed by the ‘cut back’ between the two busses.

A further mixing stage routes and mixes the 8 AES audio over input signals. These are balanced AES inputs via a D-type connector. Since each audio level within the mixer is capable of having up to 4 audio overs added to it, a choice must be made how these are to be allocated. There are 3 template options for this configuration, the selection of which is defined in the HD_MIXER.INI file (see section 3.4).

Bespoke audio configurations can be created, making the system highly flexible. The template options are:

Configuration 1 PRO-BEL_AUDIO_1.INI:

1 separate AES audio over for each of the 8 audio levels (audio overs 2 to 4 will not function)

A further configuration allows 4 of the AES input signals to be used as discrete AES PGM and PST inputs. This option is for installations that do not use embedded audio. A maximum of 2 levels are permitted in this configuration, with 2 audio overs for each level.

Configuration 4 PRO-BEL_AUDIO_4.INI:

2 audio overs for each of the 2 audio levels, all signals are separate AES inputs, including PGM and PST for levels 1 and 2

The connectors Spare 1 and 2, provide access to the two rows of eight pushbuttons below the Bypass switch control button row. These buttons can be used to control any equipment requiring a closing contact. However in systems with multi level audio, or if the panel is to provide control of more than one system, these buttons are used for that purpose and are therefore not available externally.

The Automation Port connections provide MIP (manual intervention panel) compatability with legacy Compass/Sectant automation systems. These connections enable any equipment, requiring a closed contact to be interfaced to the panel ‘Automation’ buttons.

3 TX-2330 Configuration

3.1 Introduction

This card is the central controller for the Masterpiece Mixer. This card is optional since the mixer can be controlled from an external system such as the TX500 Series Master Control Mixer, which itself will contain a TX-2330 control card. The TX-2330 can be considered as a ‘PC on a card’, and runs a real-time operating system with the core program held in ‘flash’ memory on a pluggable chip. The controller system configuration is also written to the flash memory, which may be backed up using a PC connected to the Ethernet port. Communication to most other components in the system is via built-in serial links, there are also 16 GPIs on the card. The interface to the automation system is either via an RS422 or Ethernet connection. The following diagram shows the card configuration switches and LEDs, most other components are not shown:

3.3 Configuration File

Every Masterpiece system has a system configuration file, which is held in ‘non-volatile’ flash memory. The data held in this file is critical for the correct operation of the system, and therefore it is advisable that a backup copy of this file is kept for each system. The configuration data is essentially all the details entered into the ‘Config’ screens in the TX500 control panel screen.

3.3.1 Requirements

The TX-2330 control card is equipped with an Ethernet port and an FTP Server, and it is these facilities that can be used to backup and restore the system configuration.

The file TX500Series1.cfg contains configuration data. Network.ini contains network initialisation data. All Masterpieces will be shipped with a fixed IP address configured (normally 10.1.0.116), which the user must know before they can proceed. The user will also need to connect the Masterpiece to a Local Area Network using a standard CAT5 cable and the Ethernet port on the rear of the main control frame. A PC needs to be available on the same LAN, the operation can then be carried out from the Command Prompt or using Microsoft Internet Explorer V6, or beyond.

Finally, the TX-2330 control must be put into Test Mode using switch 6, which is accessible via the front edge, after which a reset must be performed. The Masterpiece will be operational while in this mode, however, any changes made in

3.3.2 Backing up

3.3.2.1 Using Compact Flash Reader

Remove the compact flash from the 2330 TX Controller and place in a compact flash reader. This will appear as another drive within the standard windows operating system. The configuration files can then be copied, saved or edited.

3.3.2.2 Using FTP

From the Command Prompt, the user must first check communication with the TX500 by ‘Pinging’ its IP address:

If successful, the following command sequence will result in the TX500Series1.cfg file being copied onto the users C: drive:

Switch 6 OFF/UP Normal

DOWN/ON Test Mode

Reset after changing switch setting

Note that the password, when prompted, is:

*+”}.?

To restore the configuration from the same PC, the following command is used:

PUT TX500Series1.cfg

The session is closed by typing ‘Disconnect’, after which the TX500 must be put back into Normal Mode (using Switch 6), and resetting the 2330 card.

3.3.2.3 From Internet Explorer

After launching Internet Explorer, type in “ftp://” followed by the IP address of the TX500. Type in the following user name and password when prompted:

User: Pro-Bel

Password: *+”}.?

The resulting screen will show the available files, which may be saved by right mouse clicking on the highlighted file and selecting ‘Copy to folder’.

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 43

The file may be restored to the TX500 by using the PCs ‘Copy’ function in Windows Explorer, and pasting the file into the screen shown above.

3.3.3 Configuring an IP Address

The Masterpeice can only have its address changed after a successful connection has been made to the FTP server, as described in the previous two sections. The user must then retrieve the NETWORK.INI file and edit it before re-applying it to the TX-2330 control card.

The NETWORK.INI file will appear similar as follows:

3.3.3.1 [NETWORK] Section

The values stored in this section are only used when DIL switch 7 is set to ‘use fixed IP address’ (ON)

The ‘IPAddress’ field is the fixed IP address to be used. It must not have leading zeros on any part of the address (except for a single zero when the value is zero).

The ‘SubNetMask’ is the value for the network subnet mask address. This field must not have leading zeros on any part of the address (except for a single zero when the value is zero).

The ‘DefaultGateway’ is the address of the gateway used when messages need to be sent outside the local LAN. This field must not have leading zeros on any part of the address (except for a single zero when the value is zero).

The ‘DNSAddress’ value is the address of the DNS server. This field must not have leading zeros on any part of the address (except for a single zero when the value is zero). This is not currently used so should be set to 0.0.0.0.

Page 46: MASTERPIECE USER MANUAL - grassvalley.com Branding and... · Masterpiece User Manual snellgroup.com Masterpiece User Manual Issue 8 Rev 2 ...

Masterpiece User Manual snellgroup.com

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 46

The ‘EthernetCFG’ value is the setting used to set the Ethernet Port speed and duplex. The available options are: 0 (AUTO), 1 (10M Half Duplex), 2 (10M Full Duplex), 3 (100M Half Duplex) and 4 (100M Full Duplex, default). Any other value will cause the default value to be set.

3.3.3.2 [AUTOMATION] Section

The ‘Port’ field is used to define which port the software uses to listen on for automation commands coming from the network.

Note: Only one client connection is allowed on the network to the TX controller for automation commands.

3.3.3.3 [DEBUG] Section

The ‘GenMsgPort’ field is used to define which port the software uses to listen on for the remote logging functions coming from the network.

The ‘RTIPDiag’ field is used to turn on low-level network diagnostic messages (0 = OFF, 1 = ON). Under normal circumstances this value should be set to 0.

Note: Only one client connection is allowed on the network to the TX controller for remote logging functions.

3.3.3.4 [DEVICENAMES] Section

This section defines whether the TX500 supports remote connection and disconnection of the Main TX Panel and Fader Panel ports via the automation interface as well as the name of the TX500 and the names of its main panel and fader panel ports.

The ‘RemotePortSwitching’ field enables remote port switching when set to ‘1’ and disables it when set to ‘0’.

The ‘MixerID’ field is the name for the mixer.

The ‘Port#ID’ fields are for the following: -

‘Port1ID’ is the name for main panel port 1,

‘Port2ID’ is the name for main panel port 2,

‘Port3ID’ is the name for fader panel port 1, and

‘Port4ID’ is the name for fader panel port 2.

All names are a maximum of 8 characters and are used in the automation protocol (SW-P-32 command 0x19) for the remote panel switching function.

’EnableMixerName=1’ allows the name of the mixer (‘MixerID’) to be sent to the panel ports.

Page 47: MASTERPIECE USER MANUAL - grassvalley.com Branding and... · Masterpiece User Manual snellgroup.com Masterpiece User Manual Issue 8 Rev 2 ...

snellgroup.com Masterpiece User Manual

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 47

‘PortxClientMode=1’ (x = 1, 2, 3 or 4 where 1 or 2 indicates panel ports 1, 2; and 3 or 4 indicates fader ports 1 or 2) enables the specified port to operate in multi-client mode. This is used by the ‘Procion’ system to allow multiple panel clients to connect to a mixer via a single RS422 port.

‘PortxClientMode=0’ is the default mode that sets the port to operate with normal TX hardware panels.

Note: only the normal TX panel ports support mult-client mode at present.

’FaderPanelPortxTied=1’ allows the Fader panel port to be connected at the same time a its associated panel port is connected and vice versa. When the panel port is in multi-client mode then the Fader Port ‘PortxID’ needs to be set to the same name as the client name of the ‘Procion’ panel that it is tied to.

3.3.3.5 [TRANSITIONS] Section

This section defines the various effects and delay timings during transitions. The ‘DVEAutoOff’ defines whether the DVE is automatically removed from the signal path at the end of a transition (when set to 1) or left in (0). The ‘VideoSBDelay’ is the time when the video mixer switches back to its normal PGM crosspoint after the PGM bus has switched on the router. This value is used when there is no DVE in the video signal path and is expressed in multiples of 5ms.

The ‘AudioSBDelay’ is the time when the audio mixer switches back to its normal PGM crosspoint after the PGM bus has switched on the router. This value is used when there is no DVE in the video signal path and is expressed in multiples of 5ms. The ‘VideoEMBEDAudioSBDelay’ is the time when the video mixer switches back to its normal PGM crosspoint after the PGM bus has switched on the router when embedded audio is used. This value is used when there is no DVE in the video signal path and is expressed in multiples of 5ms. The ‘AudioEMBEDAudioSBDelay’ is the time when the audio mixer switches back to its normal PGM crosspoint after the PGM bus has switched on the router when embedded audio is used. This value is used when there is no DVE in the video signal path and is expressed in multiples of 5ms. The ‘VideoDVESBDelay’ is the time when the video mixer switches back to its normal PGM crosspoint after the PGM bus has switched on the router. This value is used when there is a DVE in the video signal path and is expressed in multiples of 5ms. The ‘AudioDVESBDelay’ is the time when the audio mixer switches back to its

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 48

normal PGM crosspoint after the PGM bus has switched on the router. This value is used when there is a DVE in the video signal path and is expressed in multiples of 5ms. The ‘ResetVideoMixerPort’ determines whether the background reset of the Video Mixer port is enabled or not. If enabled (set to 1) the Video Mixer port will be reset once an hour or every three consecutive messages where a response was not received, otherwise set to 0 (zero) the function is disabled.

The ‘ResetDVEPort’ determines whether the background reset of the DVE port is enabled or not. If enabled (set to 1) the DVE port will be reset once an hour or every three consecutive messages where a response was not received, otherwise set to 0 (zero) the function is disabled.

The ‘HDMixerDVE’ defines how the Master control mixer controls the operation of a DVE, if installed, on the system. Set to ‘0’ then system assumes the DVE is an external one, with the mixer taking full control of the DVE and communicates with it on its own dedicated multi-drop port. This is the default operation.

If set to ‘1’ then the control is as mode ‘0’ , but the DVE is assumed to be an internal one with communications now using the same multi-drop port as the main Video Mixer with an address 0x36h.

If set to ‘2’ then the mixer will run a DVE Simulation mode. This mode can be selected when using and external DVE that requires no communications with the Master Control. The DVE input will be switched as normal using the DVE button on control panels or automation commands. This option is only available with a frame store module installed.

The ‘ManualLAGMode’ defines the operation of the Manual Fader panel Lag button. If set to 1 then any Automation Lag operations can be overridden or cancelled by the operator pressing the Lag button in a ‘User knows best’ situation. If cleared (set to 0) then normal operation is assumed.

The ‘AudioPreviewMode’ value allows different audio routing/gain values for the same channel on different busses (PGM, PST, AUX1). When this flag is enabled (1) it allows back-to-back transitions on the same channel to have different audio routing/gains.

The following rules apply whether changed from a panel (hard or soft) or automation:

Adjusting PGM bus audio will change the audio for PGM/AUX1/AUX2 busses for the selected PGM bus channel but will only change the PST bus if the PST bus has a different channel selected to the PGM bus.

Adjusting the PST bus audio will only change the PST bus audio.

Adjusting the AUX1 bus audio will change the AUX1/AUX2 busses for the selected AUX1 bus channel but will only change the PST/PGM busses if the

Page 49: MASTERPIECE USER MANUAL - grassvalley.com Branding and... · Masterpiece User Manual snellgroup.com Masterpiece User Manual Issue 8 Rev 2 ...

snellgroup.com Masterpiece User Manual

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 49

respective selected channels on the PST/PGM busses are different to the AUX1 bus.

To use the above feature on a manual TX panel, V3.11 or above software for the hard panel or V1.18 or above software for the MCM soft panel will need to be used.

When this flag is disabled (0), the default setting, the routing/gains are applied to all busses for that channel no matter which bus it was set on.

The ‘AudioGainMode’ value allows the gains to be applied according to the input channel routing (0, default) or directly to the audio outputs (1).

The ‘UseExtendedAudioMsgPort?’ value allows the separate audio routing/gain functionality to be used on an MCM soft panel. There are two configuration values, one for panel port 1 and one for panel port 2. Setting this value to 1 will allow an MCM soft panel (must be MCM V1.18 or above) to use the separate audio routing/gain features. If a hard panel or MCM soft panel V1.17 or below is being used on a panel port then the respective setting for that port must be set to 0 (zero), the default.

3.3.3.6 [SYSTEMSETUP] Section

This section defines the expected system setup for the Status Poll to respond against.

The ‘AudioMixer’ defines if the system has an audio mixer present (1) or no mixer (0).

The ‘VideoMixer’ defines if the system has a video mixer present (1) or no mixer (0).

The ‘DSKs’ defines if the number of active DSKs present (1-4) or none (0).

The ‘AudioRouter’ defines if the system has an audio router present (1) or not (0).

The ‘VideoRouter’ defines if the system has a video router present (1) or not (0).

The ‘DVE’ defines if the system has a DVE present (1) or not (0).

The ‘PanelPort1’ defines if the system has a Panel connected to port-1 (1) or not (0).

The ‘PanelPort2’ defines if the system has a Panel connected to port-2 (1) or not (0).

Note: Setting any of these values to ‘Not present’ (0), even if there is, will force the Status Poll message to report ‘no issues’ with that device even if the mixer has lost comms or disconnected.

Masterpiece User Manual snellgroup.com

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 50

3.3.3.7 [CHANNELNAMES] Section

This section defines whether the extended channel name will be transmitted on a Panel Port. Extended Channel names consist of 8 ASCII characters as apposed to the existing 4 ASCII characters. This functionality is only possible with Aurora Controller V1.11 or greater and can only be displayed on MCM V1.16 or greater.

The ‘Port1ExtDisplayMode’ defines if the extended channel names are to be sent to Panel Port 1 (1) or disabled (0).

The ‘Port2ExtDisplayMode’ defines if the extended channel names are to be sent to Panel port 2 (1) or disabled (0).

If this feature is enabled under Local Router control, the system will send out extended channel names that are made from centring the existing 4 ASCII name in 8 characters.

Note: Enabling this functionality does not interfere with the existing channel names.

3.3.3.8 [GPIMACROS] Section

GPI Macros were developed to extend the functionality of a TX Panel system without the use of an Automation Module. They utilise the GPI numbers 17 to 48 and therefore require the 2332 GPI Expansion card to be installed.

The basic definition of a GPI Macros is an Automation command that is executed by the press of a Spare button from the TX Panel (TX520 see section 5.7, or TX510 see section 9.5.5). These commands are SW-P-32 based e.g. change the Audio Routing on a multi level system, and therefore, cannot be used on systems where Automation is already installed and used. The system only supports up to 8 separate GPI Macros and therefore 8 macro files.

Note: Only 3 can be active at one time simultaneously

Configuring GPI Macros

In order to use the GPI Macro functions, the NETWORK.INI file needs to have the correct settings as to how these macro commands are to be executed. The ‘GPIMacroEnable’ must be set to ‘1’ to enable them. The GPI Macros only operate in one of two modes, either source specific or global. (For more details see section 10.4)

Source specific means that the command being executed is performed on the current selected preset channel only. If the Source changes then the GPI Status lamps will change to indicate the status of the new channel. Global means that the command is executed system wide irrespective of the selected channel. To correctly set the mode of operation for the GPI Macro requires prior knowledge of the Automation command protocol SW-P-32.

If the ‘Source Specific’ mode is selected then the GPI Macro can show the status

Page 51: MASTERPIECE USER MANUAL - grassvalley.com Branding and... · Masterpiece User Manual snellgroup.com Masterpiece User Manual Issue 8 Rev 2 ...

snellgroup.com Masterpiece User Manual

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 51

of either the Video or Audio channel selected. If the command being executed is to change some parameters on the audio source then setting the Source Type to ‘Audio’ means the system status will only follow the preset Audio channel. Likewise, setting it to ‘Video’ will follow and display the status of the Video channel. If the sources are married then the default of ‘Video’ can be assumed.

If the ‘’Exclusive Mode’ flag is set then there will only be one GPI Macro active at one time. Pressing a subsequent GPI Button will firstly switch off the current GPI Macro button and run is associated ‘Off‘ command before running the newly selected Macro. If running in Non-Exclusive mode it is advisable not to have more than 3 Macros active at anyone time.

GPI Macros are defined in the section ‘Macro#File’, where the # is numbers 1 to 8. The files are stored on the Compact Flash card along with the rest of the system files, and their names must be in the 8.3 naming convention with the extension .MAC to indicate that it is a Macro file. If no macros are defined then the default is to leave the field empty.

GPI Macro Files

A GPI macro file is a specially formatted text file that lists the following information

[GPI]

InputGPI=#1

OutputGPI=#2

[COMMANDS]

On=FF.xx.xx.xx.xx.xx.xx.xx.xx.xx

Off=FF.yy.yy.yy.yy.yy.yy.yy.yy.yy

The InputGPI is the defined GPI number of the open collector circuit on the 2332 card that the TX Panel spare button is connected to and used to start the macro commands it is associated with. To indicate that the GPI Macro has been run, the OutputGPI is the GPI circuit number that the lamp or LED of the spare button is attached to. For details on these buttons and connections see sections 4.2, 4.4 and 5.7.

The [Commands] section list the On and Off commands that are associated with the execution of the GPI Macro. They are based on Automation style commands in terms of the hex numbers that make up the data in that message, each value must be separated by a full stop (.), see SW-P-32 for details of the messages.

The On command is executed when the macro is turned ‘on’ as defined by the InputGPI value, followed by the illumination of the lamp indicated by OutputGPI. The Off command is executed when the macro is turned ‘off’ and should ideally be the reverse conditions of the On command, followed by the de-illumination of the

lamp.

3.3.4 Remote Logging Screen

The system provides a remote logging message screen across the network using a TCP/IP connection. To switch on this feature ensure that the ‘Remote logging screen enabled’ switch (DIL Switch 5) is set to enabled, see section 5.5 2330 TX Series Control Card.

This screen will show the messages normally displayed on the VGA output which is not available on the TX rear panels.

The remote logging screen uses the windows HyperTerminal program for this function.

The HyperTerminal session needs to be configured to use a TCP/IP (Winsock) connection using the appropriate IP (TX IP) and Port (GenMsgPort value in NETWORK.ini file) address.

General text based logging messages are displayed all the time.

Various bits of logging information to do with data received/transmitted on the various ports can be toggled on/off by entering numbers on the keyboard followed by carriage return (<CR>).

The following table defines the logging information available:

NUMBER LOGGING INFORMATION

0 Displays data received/transmitted on the RS422 Automation port

1 Displays data received/transmitted on the RS422 AES Mixer port

2 Displays data received/transmitted on RS422 Panel Port 1

3 Displays data received/transmitted on RS422 Panel Port 2

4 Displays data transmitted on the UMD RS422 port.

5 Displays data received/transmitted on RS422 Fader Panel Port 1

6 Displays data received/transmitted on RS422 Fader Panel Port 2

7 Displays data received/transmitted on RS422 Router Port 1 (Depending on the configuration of the TX this is either the main video/audio router control or the DVE router control)

NO FUNCTION IF SYSTEM3/AURORA CONTROL AND NO DVE SELECTED

8 Displays data received/transmitted on RS422 Router Port 2 (RS422 router control)

3.3.5 Using DHCP

If required, the user may configure the TX500 control card to automatically request an IP address from a DHCP Server on the same LAN. This is achieved by setting switch 7 UP and resetting the module. It must be noted that there is no direct method of knowing what address has been assigned to the TX500, and the Configuration or Network files cannot be retrieved without this information. It is for this reason that the units are shipped with a fixed address.

3.3.6 GPI Macros

To add extra functionality to the TX520 panel it is possible to add simple Automation commands via Macro commands that are triggered from GPI inputs.

3.4 Mixer ‘ini’ Files

There are a number of configuration “ini” files. The principle configuration file is HD_MIXER.INI and there are a number of subsidiary “ini” files such as PRO-BEL_AUDIO_1.INI. All the configuration files are located on the SD flash card located on the mixer card.

Figure 31: SD Flash Card

To edit these files, the SD flash card must be removed and connected to an SD flash card reader on a PC, they will open in Notepad and can be edited as a standard text file and then resaved. New configurations will not be registered until the mixer is reset. The files contain remarks to assist with configuration. Only SD cards up to 2GB are supported, larger cards using SDHC format are not supported.

To remove the SD flash card; push in, until click is heard, and release.

To fit the SD flash card; push until click is heard.

3.5 Audio Transitions

Audio data from either the embedded inputs or the discreet AES inputs can be audio or Dolby. If either the channel status data/audio bit is set or a Dolby PaPb sequence is detected then the input channel is detected as Dolby, else it defaults to audio.

These settings can be modified in the audio ini file to audio, data or automatic allowing you to override the automatic settings.

When a transition occurs one of four different scenarios can occur as follows:

Both input channels are audio. In this instance a normal transition occurs with the program input fading down and the preset input fading up.

Both input channels are Dolby. In this instance, at the middle of a transition the program is cut off and the preset is cut on at a video frame boundary (Dolby guard band). If the transition is a cut and fade or a fade and cut, then the middle of the transition will be taken as the end of the cut or the end of the fade respectively.

The program channel is audio and the preset channel is Dolby. In this instance, the program channel fades down as normal until it reaches the middle of the transition (or end of a cut or fade as above), then the Dolby is cut on at a video frame boundary. Normally any downstream Dolby decoder will do a further one frame transition between the audio and Dolby when it detects a change in signal format.

The program channel is Dolby and the preset channel is audio. In this instance, the program channel cuts off when it reaches the middle of the transition (or end of a cut or fade as above), then the audio is faded up.

Note: The audio starts fading up at the start of the transition but is only switched in when the Dolby is cut off, so it is at some level above silence. Normally any downstream Dolby decoder will do a further one frame transition between the audio and Dolby when it detects a change in signal format.

3.6 Frame Store

The frame store is an optional daughter-board. Its two main functions are:

Frame delay

Logo generation

For either of these functions to work, the frame store must be indicated as present in the [configuration] section of the application initialisation file (usually HD_MIXER.INI). See section 0 above.

3.6.1 Frame Delay

The frame delay delays video data passing through the system by a whole number of frames. This is usually done to compensate for the delays inherent in other equipment such as DVEs and Dolby encoders and decoders. For a frame delay to be applied, the frame delay must be enabled and frame delay period must be set greater than zero in the [Frame Store] section of the application initialisation file.

If a DVE is included in the video path, then the frame delay will be placed at the same location (see section 7.9.4 below) and the system will normally pass video data through the frame delay and only switch to the DVE when a DVE transition is in progress.

Note: The delay caused by an internal DVE can also be configured. If there is no DVE, then the frame delay is always placed after the last DSK.

3.6.2 Logo generation

For logos to be generated, the logo generator must be enabled, a logo initialisation file specified and a logo keyer specified in the [Frame Store] section of the application initialisation file.

The logo generator provides key and fill data that is directed to the specified keyer; that keyer works completely normally except that the logo generator’s data is used and any input on its external key and fill inputs are ignored. All existing keyer control and adjustment is available on the logos (e.g. cut, fade, follow, clip and gain adjustments).

The logo generator is further configured by setting up a logo initialisation file (typically named LOGO.INI) and providing one of more logo image files. Logo images are Truevision TARGA files, such files typically have the extension ".tga". The format can store image data with 8, 16, 24, or 32 bits of precision per pixel. 32-bits per pixel is recommended – with 8 bits each for red, green and blue plus 8 bits for alpha (transparency) information. Lossless run-length encoding may be beneficially applied resulting in smaller files and reduced load times.

The Logo files must be copied to the SD memory card used for mixer configuration. Where several logo image files are present, it is recommended that they are placed in a LOGO folder on the SD card.

Logos must be created to suit the pixel size required. The Mixer does not scale logos for different screen resolutions nor does it modify the loaded logo for different screen aspect ratios. Logo files must be created for the format required.

There is no limit to the number of files that can be stored on the SD card other than card’s storage capacity. Currently, the largest SD card possible is 2 Gbytes.

The logos to be used are defined in the logo initialisation file (usually LOGO.INI) on the SD card. This file defines the files to be copied into the Frame Store’s high

speed memory on power up. Small logos are loaded in a few seconds, but very large logos can take several minutes. The amount of logo image data that can be stored in high-speed memory is very large – equivalent to more than 10 frames of high-definition video.

Up to 16 distinct logos can be loaded, but the control system is restricted to selecting between logos 1 to 4. Each logo may be a single static image or it may be an animation comprising a sequence of images.

Loading a large amount of logo data can take a significant time. Setting the logo late load parameter in the application initialisation file (usually HD_MIXER.INI) to TRUE will cause the masterpiece to load logos only after other functionality has started up. Using this facility gets basic functionality working as soon as possible, but logos will not be available until they have been loaded and this will take more than twice as long as before.

If the logo .ini file or the Targa files themselves are changed, they can be reloaded by toggling one of the switches DIL switches. Logos will not be generated while the reload is in progress. See section 3.8 below.

3.6.2.1 Logo GPIO Control

The logo generator can switch between up to 4 different logos from GPI controls on the rear of the mixer. There are eight individual GPI controls, nominally numbered 1-8. GPI control allows two modes of operation:

Mode 1:

GPIs 5-8 inclusive are used to select between the four logos to be displayed. GPIs 1-4 work in parallel with the first 4 and select the same four logos. Each GPI is a momentary connection to 0V.

Using two sets of four GPIs allows (for example) automation control into GPIs 1-4, and manual control into GPIs 5-8. Each GPI is latched low, and the status of the second set of four changes to reflect the first set (and vice versa). This means any changes to the manual selection will be reported back to the automation, and vice versa.

Mode 2:

GPIs 5-8 control logo selection just as in mode 1.

GPI 0 sets an animated logo to the beginning of the animation sequence.

GPI 1 pauses the animation sequence.

GPI 2 starts the animation sequence.

GPI 3 has no function and is reserved for future use.

Example using TX control panel spare buttons:

As an example the logo control could be performed by the spare buttons on the TX control panel.

Note: An external 5V supply is required for the LED’s.

Assigning spare buttons 1 to 8 to GPIO’s 1 to 8, the wiring between connectors would be as follows:

3.6.2.2 Logo Initialisation File

An example of a logo initialisation file is presented below. The example defines a single non-animated logo.

Up to 16 logos may be stored in high-speed memory, although ; the GPIO based control system only permits the selection between four ; logos and without this the first logo is automatically selected. ; ; The logo generator system supports a variety of effects ; ; Enabled ; ; A logo must be enabled in order to be seen.

The integer and numerator may be ; positive or negative, but must be even. The denominator must be positive. ; ; On every frame, the integer velocity values are added to the coordinates ; and on every frame number exactly divisible by the denominator, the ; numerator is added (unless the denominator is zero, in which case ; numerator is ignored). It is possible to use these parameters in ; combination with other animation effects to achieve slow, smooth ; movements, but the details are too complex to go into here. ; ; Note that no part of the logo can be allowed to go past the edge of the ; screen.

3.6.2.3 Animated Logos

Animated logos can be loaded as a sequence of TARGA files. Various animation options can be configured by setting parameters in the LOGO.INI file. Options include intermittent motion, stepping slowly through a sequence of stills and having a logo move across the screen.

A simple animation that shows a different image on each frame in a continuous loop may be defined as in the example given below:

logo 1

enabled = TRUE

persistence = 0

…{other parameters}…

animation_running = TRUE

animation_timer = 1

animation_on_time = 0

animation_off_time = 0

…{other parameters}…

filename = B:\LOGOS\probel01.tga

filename = B:\LOGOS\probel02.tga

filename = B:\LOGOS\probel03.tga

filename = B:\LOGOS\probel04.tga

filename = B:\LOGOS\probel05.tga

…{more filenames}…

filename = B:\LOGOS\probel30.tga

An animation with intermittent motion can be defined. The example given below will step through the animation sequence for 30 frames by the end of which it will have looped back to rest on the first frame; the first frame will then be displayed for 60 frames before the animation cycles again.

3.7 Internal DVE

The internal DVE is an optional daughter-board. Its purpose is to provide Digital Video Effects.

For the DVE to work, the internal DVE must be indicated as present in the [configuration] section of the application initialisation file (usually HD_MIXER.INI). See section 0 above.

The [DVE] section of the application initialisation file must correctly indicate the DVE’s main code filename and a DVE initialisation file (see section 3.7.1).

The DVE delay delays video data passing through the system by a whole number of frames. It is usual to include a frame delay in a system with a DVE so that the system will normally pass video data through the frame delay and only switch to the DVE when a DVE transition is in progress. When the DVE is not in the main path it is available to preview DVE moves.

Note: The delay caused by an internal DVE and the frame delay can be configured independently, but they will normally be matched. If there is no frame store, video data will always be passed through the DVE.

3.7.1 DVE Initialisation File

The control system can trigger any one of 24 transitions. Exactly what each one of those 24 transitions actually does is configured by the DVE Initialisation File.

The example DVE .ini file below shows how a transitions number can be assigned to a built in transition with optional modifiers such as duration and limit. And it shows how transition numbers can be assigned to user defined sequence files with optional modifiers that control movement between keyframes. User defined sequences are usually generated using a PC based tool such as the DVE Move Editor.

If the DVE Initialisation file or sequence files themselves are changed are changed, they can be reloaded by toggling one of the switches DIL switches. Reloading cannot be done while a DVE transition is in progress. See section 3.8 below.

; ; DVE Initialisation file ; ; Note: in this file, all text on a line following a semicolon is a comment. ; ; This file defines the behaviour of the DVE for each of 24 transition numbers. ; Each of the 24 transitions numbers may be allocated to either a built-in DVE ; transition using the following syntax ; ; transition number nn = mmm ; ; Where nn is a number between 1 and 24 and mmm is the number of a built-in ; transition. Built-in transitions are numbered from 100 onwards as detailed ; in the table below. ; ; Built in functions may be provided with the following optional parameters:

; ; duration = fff ; limit = pp.p% ; ; Duration specifies the time that the transition will take and is specifed ; in units of frames. The default duration is 100 frames. ; ; Limit specifies how far through the transition will be executed and is ; expressed as a percentage in the range 0.1% to 100.0%. For example, with a ; limit of 50% a transition will stop when it is half way through. ; ; Alternatively, a transition number may be allocated to a user-defined ; transition that is described by a keyframe sequence file. In this case, use ; the following syntax. ; ; transition number nn = ssssss ; ; Where ssssss is a full path name identifying a transition sequence file. ; For example: : ; transition number 10 = B:\TRANSITIONS\mytransition.seq ; ; Note that: sequence files will usually be on the SD card (identified as ; drive B; it is good practice to keep transitions in a separate subfolder ; here identified as TRANSITIONS; file names should not contain two or more ; consecutive spaces; and, file names should end with the suffix .seq. ; ; Sequence files may be conveniently generated by using a PC utility such as ; the Snell DVE Move Editor. ; ; The total number of keyframes that may be specified in user-defined ; transitions may not exceed 100. ; ; User defined transitions take a number of additional optional parameters. ; The spline interpolation between keyframes is determined by an implementation ; of a Kochanek–Bartels spline function. This function takes three parameters ; each typically in the range -1.000 to +1.000 but are permitted to range from ; -9.000 to +9.000: ; ; curviness tension ; curviness bias ; curviness continuity ; ; The default values used are as follows. These give a strictly linear ; interpolation: ; ; curviness tension = 1.0 ; curviness bias = 0.0 ; curviness continuity = 0.0 ; ; A popular alternative is given below. These give a Catmull–Rom spline: ; ; curviness tension = 0.0 ; curviness bias = 0.0 ; curviness continuity = 0.0 ; ; The DVE features a large number of built-in transitions. The available ; built-in transitions are listed below, note that those built-in transitions ; marked with "warp" may not be available in all installations. ; ; Built-in Transitions ; ; 100 ;zoom centre ; 101 ;zoom top ; 102 ;zoom right, ; 103 ;zoom bottom ; 104 ;zoom left ; 105 ;zoom top left ; 106 ;zoom top right ; 107 ;zoom bottom right ; 108 ;zoom bottom left ; 109 ;push top ; 110 ;push right ; 111 ;push bottom ; 112 ;push left ; 113 ;push top left ; 114 ;push top right ; 115 ;push bottom right ; 116 ;push bottom left ; 117 ;squeeze top

3.9.5 Power Up LED sequence

On power up, the Processor will load firmware from the SD card and then program each programmable device in sequence. The LEDs will therefore flash continuously in sequence from Processor 1 to Processor 7 as each device is programmed. LEDS will be skipped if the particular option is not fitted (e.g. if the DVE is not fitted the Processor 7 LED will not flash).

Note: Logo files may take several minutes to load, depending on the size of the logo and if it is animated. Therefore LED 5 will flash continuously during this process.

If this sequence is not completed, or the LEDs flash in an error code, refer to the table above for details.

4.2 TX520 panel button configuration

The TX520 control panel has 2 banks of 8 buttons that are hardware assignable to be multi-purpose. The TX510 control panel also has assignable buttons, and these are documented in section 8.5.5.

On the TX520 control panel these buttons can be used for ‘internal’ purposes, and must therefore be under control of the control panel processor, or they may be used for ‘external’ purposes, in which case they are wired to connectors on the rear panel. The buttons are configured by moving ribbon cables inside the control panel to different connectors, as documented in this section.

When used for internal use the buttons have the following purpose:

SPARE1 OR MULTI-LEVEL AUDIO MONITORING BUTTONS

SPARE2 OR MULTI-CHANNEL ASSIGN BUTTONS

To change the assignment of these buttons the control panel lid must be raised, if necessary by first releasing the screw under the ‘Pre-roll & Take’ button. Located on the underside of the top circuit board are four connectors, with silk-screened instructions, as follows:

SPARE 1BUTTONS

SPARE 2BUTTONS

PL 6

PL 7 PL 9

PL 8

CONNECT PL 6 TO REAR PANELOR CONNECT PL 6 TO PL 7

CONNECT PL 8 TO REAR PANELOR CONNECT PL 8 TO PL 9

When either pair of connectors are linked using the ribbon cable, the buttons take on their internal function, and when either PL6 or PL8 are connected to the rear panel they may be used externally by the user. For external use the rear connectors, labelled as SPARE 1 and SPARE 2.

4.3 2235 Fader Panel

The 2235 is the TX500 Series fader panel, which is an optional system component and has 8 motorised faders for controlling the audio overs, the lead and lag functions and the master level. The unit consists of a 2237 main processor board, and a 2239 sub-module, with associated button and connector assemblies. There are also dual redundant 12V block power supply units.

Configurable items are the Baud Rate (SW4), the half-second delay (SW5), voice over fader reverse (SW6) and the calibration of the faders (SW3).

SW4 sets the RS485 Baud rate. DOWN (NORMAL) is 38k4, UP is 115k2.

SW6 controls the order of the voice over faders. UP (NORMAL) the order of the VO faders are, left to right VO1 to VO4. DOWN (REVERSE) the order of the VO faders are, left to right VO4 to VO1.

The half second delay (SW5 UP: DELAY IN) is used to stop a second panel in a two-panel system from juddering in response to a slow manual fade on the first

panel.

For example, if one panel is inside a sound booth and the other outside, when an operator manually ‘rides’ a fader outside the booth, the one inside will remain still until the operation is finished. This may be useful in some situations to prevent mechanical fader noise inside the booth.

The delay is timed from the last message-in, detected on the panel port. Each panel can be set either way, as suits its physical location.

Setting SW5 DOWN (NO DELAY) removes this delay and the faders respond to messages immediately. In a single-panel system, it is recommended to set SW5 DOWN.

SW3 sets calibration mode. All other switches are unused and should be left UP.

The calibration affects the ballistic response of each fader to the data that it represents. Poor calibration may cause the fader to over or under-shoot it’s required position when remotely driven.

To check the calibration, a PC running Hyper Terminal is required, configured for 9600 BAUD, 8 data bits, no parity, 1 stop bit.

Proceed as follows:

holding the thumbscrews, open the lower front panel of the unit

check the 8 way DIP switch on the main processor board is set as follows:

Connect the PC RS232 COM port to SK1 of the main processor board with a pin to pin cable, launch Hyper Terminal

Set SW3 position 0 down and re-power the unit, or press the rest button, a test menu will appear on the PC

Select test number 7, the following will appear:

Press Ctrl + E on the keyboard twice in order to cycle the faders in 0.5 second fades

The faders should move up and down together when the panel is set at its normal operating angle

If any of the faders lead or lag adjust the ‘clock divide Up’ or ‘Down’ as appropriate until they synchronise (follow the instructions at the bottom of the Hyper Terminal screen)

Finish by setting SW3/0 back to its normal position, and re-power the unit. The data will be retained in non-volatile memory.

Notes: ‘Mark time up’ and ‘mark time down’ are very coarse calibration figures. ‘Clock divide up’ and ‘clock divide down’ are for finer adjustment. (Mark time up and down measurements are 16-bit numbers that looks for a 1 or a 0 in each position. If the number is 0FFF and you wish to increase the speed it becomes 1FFF. To decrease, it becomes 07FF. Each digit should only be 0,1,3,7 or F. All digits to the right of the bit being modified are 1s and all to the left 0s. Each fader panel when shipped has a table taped to the inside with the factory settings used. This will give some indication should values be completely altered. To enter a new ‘clock divide up’ value for fader 2 (lag) the user must enter 2,2,30, for instance, to increase the drive to that fader from the example shown.

Within the diagram the title is ‘1 CHANNEL1 A1 CHANNEL2 A2 234’, where ‘1’ is the page number, ‘CHANNEL1’ is the channel name, ‘A1’ is the channel routed, ‘CHANNEL2’ is the channel name, ‘A2’ is the channel routed and ‘234’ indicates that either A1 or A2 is also on routed on levels 2, 3 and 4.

If there is no communication with the routing system then the page title is displayed as ‘1 CHANNEL1 A? CHANNEL2 A? ???’, indicating that the audio inputs may be routed on other levels.

5.1.2 Page and Home Buttons

In a single level system the <PAGE> button performs no action, whilst in a multi-level system it allows monitoring of the different audio levels to be cycled through. On each page button press the title of the page changes to reflect the audio levels being monitored.

On submenu screens, where the <PAGE> button is active, a rectangle is drawn on the screen above it, whilst the <HOME> button always forces the screen back one page.

5.1.3 Real Time Clock

In stop-watch mode the time of day display (HH:MM:SS) is provided in 24 hour format, as illustrated. This time is derived from the station TC input. If no input is present, the clock will free run.

5.1.4 Stop-watch and Timer Modes

The timer modes shown on the plasma display are configurable. For details of how to configure them, see section 6.1.5.1. The subsequently available modes are either stop-watch or timer mode.

The options selectable on the left hand side of the plasma display in each mode are as follows:

5.1.4.1 Stop-watch Mode

If stop-watch mode is selected then the current count is displayed along with three button controls for the stop watch, as illustrated. The stop-watch can count up or down (from a preset value) and can be reset. The count down preset value is selected using shaft encoder one to set the MMM value. The shaft encoder second from the left is used to set the SS value.

The stop-watch is locked to the station TC input. Due to this feature a count started half way through a second will count that half second as a second to keep in step with the station TC.

The stop-watch, once started counts continually until terminal count, and does not stop once display pages are changed.

A toggle button provides <START/STOP> indication. On system start-up the stop-watch is shown as stopped, after which it always displays the current operational state as set by the operator. When the stop-watch reaches terminal count (999:59 or 000:00) the count state is changed from start to stop.

A button provides <COUNT UP> and <COUNT DOWN> indication. On system start-up the stop-watch is shown as counting <UP>, after which it always displays the current operational state as set by the operator. When the stop-watch reaches terminal count (999:59 or 000:00) the count direction indication remains unchanged in its current state.

A button provides stop watch <RESET>. If selected while counting up the count is reset to zero and the count continues, if selected while counting down the preset count down time is reloaded and the count continues.

5.1.4.2 Segment Timer

In segment mode the timer value is displayed along with four button controls. In this mode, the timer is always active and counts independently to the stop-watch and segment count, even if timer mode is never selected.

It is always automatically started at the start of each transition and can be manually started and stopped once counting. Once started the timer counts up each second and can only be stopped manually or when the terminal count of 999:59 is reached.

At the start of each transition the timer always counts up from the zero. The <SEG HOLD> button stops the count from being zeroed at the start of each transition.

The timer is locked to the station TC input. Due to this feature a count started by a transition half way through a second will count that half second as a second to keep in step with the station TC.

The <RESET> button resets the count to zero from where it continues.

5.1.4.3 Remainder Timer

In remainder mode the timer value is displayed along with three control buttons. In this mode, the timer is always active and counts independently to the stop-watch and segment count, even if timer mode is never selected.

It is always automatically started at the start of each transition and can be manually started and stopped once counting. Once started the timer counts down each second and can only be stopped manually or when the terminal count of -999:59 is reached.

The preset value is selected using the first shaft encoder to set the MMM value. The second shaft encoder is used to set the SS value. At the start of each transition the timer counts down from the preset value or zero if none has been specified.

The timer is locked to the station TC input. Due to this feature a count started by a transition half way through a second will count that half second as a second to keep in step with the station TC.

The <ENTER>button only appears if the remaining count has been stopped and a positive remaining time is visible on the display. Selecting this button calculates the duration of the programme remaining from the last transition by performing the calculation shown. The button is then removed from the display and the duration is displayed as the remaining count, which is automatically started (the <START/STOP> button automatically toggles from stop to start).

Duration = currently remaining count - (time of day - time of transition).

Masterpiece User Manual snellgroup.com

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 86

6.1.2 Audio Monitoring Home Page

The audio monitoring home screen displays a set of dual channel audio meters for the PGM, PST, AUX busses and return TX/ On Air feed, a stopwatch/ timer display, station clock and ‘soft’ buttons permitting the operator to access other control screens.

Note: there is no PPM data available with the Masterpiece Mixer.

Four stereo meters are displayed for the PGM, PST, AUX and TX audio channels. Double width markers on each bar indicate the line-up level for the meter.

Display features for the Audio Monitoring home page, such as meter type (PPM or VU), scale and the peak bar duration are determined by the system configuration.

6.1.3 Page Title

In a single level system, the page is titled with the first two channel names specified, for example; ‘CHANNEL1 CHANNEL2’ as shown in the previous diagram.

While the page title in a multi-level system takes the following format;

page (level) number, level names, the channel routed and any other page (level) numbers where these levels are also routed.

In the diagram below, the title is

‘1 CHANNEL1 A1 CHANNEL2 A2 234’, where;

‘1’ is the page number,

‘CHANNEL1’ is the first level name and ‘A1’ is the channel routed to it,

‘CHANNEL2’ is the second level and ‘A2’ is the channel routed to it,

snellgroup.com Masterpiece User Manual

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 87

‘234’ indicates that either A1 or A2 is also on routed to either of the levels on pages 2, 3 and 4.

If there is no communication with the routing system then the page title is displayed as ‘1 CHANNEL1 A? CHANNEL2 A? ???’

6.1.4 Viewing Multi-level Audio Metering

In a multi-level system, the metering for each audio level can be viewed on individual pages. These pages can be cycled through by pressing the title bar on the touch screen (shown with a dotted outline).

On each press, the screen changes to show the next audio level and the title bar updates to show the details for the new audio level being monitored.

6.1.5 Stop watch and Timer Modes

The timer modes shown on the display are configurable. The subsequently

Page 88: MASTERPIECE USER MANUAL - grassvalley.com Branding and... · Masterpiece User Manual snellgroup.com Masterpiece User Manual Issue 8 Rev 2 ...

Masterpiece User Manual snellgroup.com

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 88

available modes are either stop watch (TOD) or timer mode.

Each timer mode has a dedicated set of control pushbuttons, available on the timer home page, these are shown below.

6.1.5.1 Stop watch Mode (TOD)

In stop watch mode the time of day display (HH:MM:SS) is provided in 24 hour format, as illustrated. This time is derived by the station TC input. If no input is present, the clock will free run.

The stop watch is locked to the station TC input. Due to this feature a count started half way through a second will count that half second as a second to keep in step with the station TC.

When stop watch mode is selected, the current count is displayed along with three push button controls for the stop watch, as illustrated. The stop watch can count up or down (from a preset value) and can be reset. The count down preset value is selected using the left hand shaft encoder to set the minute (MMM) value and the right hand shaft encoder to set the second (SS) value.

The stop watch once started counts continually until terminal count, and is not affected by display pages being changed.

A toggle push button provides <count> indication. On system start-up the stop watch is shown as stopped, after which it always displays the current operational state as set by the operator. The button is highlighted when running. When the stop watch reaches terminal count (999:59 or 000:00) the count state is changed from start to stop. The timer can also be started and stopped from the audio monitoring home page by pressing the timer indicator MMM:SS

A toggle push button provides <Up> and <Down> indication. On system start-up the stop watch is shown as <Up>, after which it always displays the current operational state as set by the operator. When the stop watch reaches terminal count (999:59 or 000:00) the count direction indication remains unchanged.

A push button provides stop watch <reset>. If selected while counting up the count is reset to zero and the count continues. If selected while counting down, the preset count down time is reloaded and the count continues.

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 89

6.1.5.2 Timer Mode

If timer mode has been configured, the display can be switched between segment and remaining mode. In either mode, the TOD display is replaced with a display showing the time the last transition was made. This is updated after every PST/PGM transition.

The timer is locked to the station TC input. Due to this feature a count started by a transition half way through a second will count that half second as a second to keep in step with the station TC.

6.1.5.3 Segment Timer

In segment mode the timer value is displayed along with four push button controls. The segment timer counts independently of the stop watch and remaining count and it is always active, even if timer mode is never selected.

After each transition the timer automatically starts, counting up each second, and can only be stopped either manually or when the terminal count of 999:59 is reached.

The <SEG HOLD> push button overrides the auto start by preventing the count from being zeroed at the start of each transition.

The <RESET> push button resets the count to zero. If the count is running when this is pressed, it will reset to zero then continue counting.

6.1.5.4 Remainder Timer

In remainder mode the timer value is displayed along with three push button controls, and counts independently from the stop watch. The segment count is always active, automatically starting after each transition, counting from the preset value, or zero if none has been specified. Also, it can be manually started and stopped once counting.

Once active the timer counts down each second and only can only be stopped manually or when the terminal count of -999:59 is reached.

The time preset is set using the left hand shaft encoder to set the minute (MMM) value, and the right hand shaft encoder is to set the second (SS) value.

The <ENTER> push button only appears if the remaining count has been stopped and a positive remaining time is visible on the display. Selecting this push button calculates the duration of the programme remaining from the last transition by performing the calculation shown. The push button is then removed from the display and the duration is displayed as the remaining count which is automatically started (the <COUNT> push button automatically toggles from stop to start).

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 90

Duration = currently remaining count - (time of day - time of transition).

6.2 Screens Accessible From the Home Page

The ‘soft’ buttons at the left and right hand sides of the display permit the operator to access the system and configuration pages. Each of these pages has a <HOME> ‘soft’ button in the lower right corner, and pressing it will return the display to the home page.

Where multiple pages are available on a screen, a <Next Page> ‘soft’ button, allowing them to be selected, will be available.

The following diagram shows the home page menu tree structure, detailing the screens which are directly, and indirectly, accessible from the main home page.

7.2 Changing the Configuration Page PIN

From the system configuration page, select the <PIN SETUP> button. The change configuration PIN screen will then be displayed.

A focus rectangle highlights the ‘active’ screen area, prompting the user first to enter a new PIN then, after four digits have been entered, to verify the PIN by re-entering it. For this page the hyphens are replaced, after each button press, with asterisks indicating that the button presses have been read.

If the new and verify PINs match, the change configuration screen is closed, and the display returns to the system configuration page.

If the new and verify PINs do not match, the page is redrawn to its initial state, allowing the operator to retry the operation.

The <PAGE> button is inactive, whilst the <HOME> button returns to the system configuration page without affecting the currently selected PIN.

7.3 Transition Rates

To access this page from the system configuration page, press the <TRANS RATES> button.

Masterpiece User Manual snellgroup.com

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 96

7.3.1 Changing Transition Rates

The transition rate setup page allows the three transition rates for the system to be adjusted and set. These three rates, <SLOW>, <MED> and <FAST> determine the rate a PST/PGM transition occurs at, and are recalled by selecting a transition rate button from the bottom left hand corner of the control panel.

Each of the three current settings is shown on the right of the screen as the number of frames over which the transition will occur.

The default settings are:

Fast = 12 frames

Medium = 25 frames

Slow = 50 frames

Each rate is adjusted by using the shaft encoder directly below the relevant bar on the screen. Turning the shaft encoder clockwise increases the number of frames, while turning it anti-clockwise decreases the value. The bar, and numeric value beneath it, reflects the changes being made. The new settings will not take effect until they have been saved. To save a new setting, press the button on the right of the screen corresponding to the rate that has been altered. The figure displayed will change to that shown below the corresponding bar.

Note: All transition rates are nominally in units of frames but are really, strictly speaking in units of double-fields. Video standards e.g. 720p60 and 1080i60 both have 30 double-fields per second.

7.3.2 Configuring ‘flip-flop’ For Transitions

The <FLIP FLOP> button at the bottom left of the transition rates page can be toggled to enable (button highlighted) or disable (button not highlighted) flip-flop operation. Flip-flop mode, when activated, swaps the PST and PGM sources at the end of a PGM bus transition.

Note: When using the TX 500 with Snell automation systems, it is important to ensure that Flip Flop mode is NOT active as the action of selecting sources on the PST bus inserts manual events into the schedule.

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 97

7.4 Configuring Fade to Black Options

It is possible to adjust the fade rate for the ‘fade to black/silence’ button. Additionally, the fade to Black can be changed to be fade to colour. Access to the fade to black page is by pressing the <FTB> button on the system configuration page.

7.4.1 Fade to Black Rate

The shaft encoder below the fade to black rate bar adjusts the fade rate, and is displayed in frames. The possible range of values is between 0 and 99 frames, where 0 = cut. The bar, and numeric value beneath it, reflects the changes being made. Once the rate has been set, pressing the <TAKE RATE> ‘locks’ the new rate, indicating it alongside the button.

7.4.2 FTB Colour Selection

Not implemented at present. Pressing the <FTB COLOR> button provides the ability to set the TX 500 to fade to a colour rather than to black. Colours available are Black, Red, Green or Purple.

snellgroup.com Masterpiece User Manual

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 101

The following diagram shows pages that are accessible from the source assign sub-menu. Some of the menu items access further pages (e.g. <Edit Names>) while other menu items (e.g. <Route Confg>) provide toggle operation around the available options. Buttons indicated with a * access sub-menu screens. The sub-menus associated with these buttons are shown in the following pages with their descriptions.

7.6.1 Router Configuration

the Ext Rtr (Aurora) port on the TX Series controller.

For external router control via an Aurora controller to operate, the router configuration page must be set for either '<EXT FIXED>' or '<EXT AUTO>'. In addition, the physical link between the Aurora and TX Series controller is via a single RS-422 link between the TX 500 controller, Aurora port, and a panel port on the controller.

The TX 500 emulates 2 Multi-drop panels on this port, at the first and second positions. The panel type used is ‘Master Control’ and each panel should be configured with a different suite number (refer to the control system documentation for further details). The first panel is used to control the Video crosspoints (PGM, PST, AUX 1 and AUX 2), while the second panel is used for Audio crosspoints (PGM, PST, AUX 1, AUX 2 and Over).

Note: If dedicated overs are used the last destination, over, is not required. This interface then operates in one of two modes as follows.

7.6.1.1 Mode 1 - <Ext FIXED>

In this mode all assignments to channels are made separately using a channel assignment panel connected to one of the panel ports on the Aurora controller. This panel should be configured to use video and audio panels with the same suite numbers as the ‘pres panel’. Any assignment to channels made from this panel will then be reflected on the TX 500.

7.6.1.2 Mode 2 - <Ext Auto>

In this mode the assignments to the channels are set as described for the Ext Fixed mode, via a channel assignment panel, however they are not fixed. The TX 500 will assign a source to a channel, if the source requested on the automation port is not currently assigned to the panel.

When a command to set a channel, on a bus is received from the automation port, the channel number is assumed to be equal to the association number on Aurora. This source association number is assigned to a channel. The video and audio suites are expected to have the same panel assigned (they will always have the same source association assigned for both video and audio.)

When a source is requested via the automation port, the TX 500 will check the source association against those sent by the system controller and if found, the matching channel will be used. If it is not found, then the highest unused channel will be assigned that source association. The maximum number of channels that can be automatically assigned is 8 (channels 13 to 20). These sources are assigned from the right hand side of the mixer bus.

It is also possible for the automation system to remotely assign source associations to channels, this is detailed in SW-P-32 (Automation Control

Protocol).

7.6.1.3 Local Router Communications

The button <RS422/RS232>, toggles between the RS422 and RS232 half of the button being highlighted. This allows the comms link between the controller and an externally connected router to be either RS422 or RS232.

7.6.2 Source Names

The <SRC NAMES> button cycles between the options: 'local', 'external - system3' and 'external - automation' for selection of source names. If the local option is selected then the button immediately below is displayed to allow the local editing of the source names. If either of the external choices are selected then the button immediately below is removed from the display as that option has no meaning when the source names are coming from an external device. On pressing the <EDIT NAMES> button the operator is taken to the source name editor page.

This page provides the source name editor, which allows all twenty-four source names to be edited on-screen. As each source name is edited the change can be seen within the four character source name displays in the lower half of the panel. Each source name is four characters long and is numbered (1-24). The characters available for the source names are:

0123456789

ABCDEFGHIJKLMNOPQRSTUVWXYZ

abcdefghijklmnopqrstuvwxyz

space character '

The four shaft encoders are used to cycle through these characters for the source names. Shaft encoder one changes the first letter of the four character name, shaft encoder two the second etc. The characters available do not wrap around, stopping on the first and last characters.

Two buttons are provided to move the focus rectangle around the screen display. The source name, highlighted with a rectangle is the one currently being edited.

Masterpiece User Manual snellgroup.com

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 104

The focus rectangle wraps around the first and last source names to allow a continual cycling.

Note: Sources 21 to 24 are displayed on the Aux bus only, using the row of 4 buttons to the right of the Aux bus.

The <PAGE> button is inactive, whilst the <HOME> button returns to the source setup page.

7.6.3 Pre-roll

On pressing the <PRE ROLL> button the operator is taken to the source pre-roll time editor page.

This page provides the source pre-roll time editor and allows the pre-roll times for the first twenty sources on the buses to be edited on screen. The pre-roll times are displayed next to the source name. The pre-roll time is displayed in seconds between 0 and 62. Where ‘- -‘ is displayed, it indicates no pre-roll for the channel. i.e. A pre-roll command will not be sent on the Preset port for the <ROLL> and <PRE-ROLL/ TAKE> buttons.

All four shaft encoders provide the same control which allows the range of seconds to be cycled through.

Two buttons are provided to move the focus rectangle around the screen display. The source name that is bound by the rectangle is the one that is currently being edited. The focus rectangle wraps around the first and last source names to allow a continual cycling.

The <PAGE> button is inactive, whilst the <HOME> button returns to the source setup page.

7.6.4 VTR Sources

On pressing the <VTR SRCS> button the operator is taken to the VTR control sources editor page.

This page provides the editor, which assigns RS-422 router source numbers to the sources on the buses. The router source numbers correspond to RS-422 router inputs and are used by the TX 500 main controller to route its control port on the RS-422 router to allow control of the VTRs.

The VTR control sources are displayed next to the bus source names with '- -' indicating no VTR source or a number in the range 1 to 64 indicating the RS-422 router source number.

In the control connections VTR1 is connected to source (input) 15 of the RS-422 router. In the screen layout the VTR source number 15 is assigned to the bus source which is 'VTR1'. The same RS-422 source can be used with more than one mixer source.

The Machine Control port should be cabled to the router as follows;

VTR1 - Controls the machine on the PST bus, VTR2 - The Aux1/2 machine and VTR3 - provides the RS422 router control to its remote control port.

All four shaft encoders provide the same control which allows the range of numbers to be cycled through.

Two buttons are provided to move the focus rectangle around the screen display. The source name that is bound by the rectangle is the one currently being edited. The focus rectangle wraps around the first and last source names to allow a continual cycling.

The <PAGE> button is inactive, whilst the <HOME> button returns to the source

setup page.

7.6.5 VTR Destinations

On pressing the <VTR DEST> button the operator is taken to the VTR control destination editor page.

This page provides the editor, which assigns the RS-422 router destination numbers, which the TX controller will use to control the VTRs from. When a VTR is to be controlled, the VTR control source number is routed to this destination on the RS-422 router making the duplex link from which the VTR can be controlled. This depends on which router bus is in use.

The VTR control destination is displayed on a single line with ‘- -’ indicating no VTR control destination or a number in the range 1 to 64 indicating the RS-422 router destination number.

All four shaft encoders provide the same control which allows the range of destination numbers to be cycled through. After a VTR destination has been changed, an <UPDATE> button is displayed in the lower right hand corner of the display. Pressing the associated soft button accepts the new value.

VTR1 port 1 = PST, VTR2 port = Aux 1 or 2, VTR3 port = RS422 router control.

The <PAGE> button is inactive, whilst the <HOME> button returns to the source setup page.

7.7 Router Destinations

On pressing the <ROUTE DESTS> button the operator is taken to the Local router destination editor page. This page allows the destinations for the TX 500 video and audio buses along with the PGM follow destinations (see section 7.8) to be specified on the local router. For systems with a system controller providing the interface between the TX system and router, settings on this page will have no effect on system operation, except audio over, where ‘- -’ indicates the use of dedicated audio over inputs, and ‘NN’ specifies the destination number for routed audio over inputs.

The local router destination is displayed next to the bus name as a number in the range 1 to 64 or a ‘- -’ indicating there is no destination for this bus.

All four shaft encoders provide the same control, which allows the range of destinations to be cycled through. The range of values displayed may 'jump' as the editor does not allow the same destination to be specified more than once. The destinations specified have to include any offsets required to stack the commands down a single RS-422 port.

Two buttons are provided to move the focus rectangle around the screen display. The bus name, which is bound by the rectangle, indicates the one currently being edited. The focus rectangle wraps around the first and last source names to allow a continual cycling. The diagram below shows typical router destination numbers for a system with a local SDV and AES router configured as two ‘TX Series’ levels.

The <PAGE> button is inactive, whilst the <HOME> button returns to the source setup page.

7.8 PGM Follow

The TX Series provides a programme follow facility, for use with systems using Local routing, allowing up to two, video/ audio, router outputs to ‘follow’ the main PGM bus.

These additional busses, PGM 1 and 2, provide cuts only transitions and can be used as a ‘shadow’ output for the PGM bus. These can be fed into an emergency/ bypass switcher, or be used to provide ‘clean’ outputs for recording, or other as regional feeds. For these to operate correctly, each bus should be assigned a destination number to control (see section 0) and source associations to select.

Source associations can be set for each ‘follow’ bus, with independent control over video and audio (providing all audio levels in multi-level systems are married) outputs, enabling PGM breakaways to be achieved.

From the source setup page, pressing the <PGM FOLLW> button takes the operator to the video and audio PGM follow associations editor main page. This page enables the video and audio follow source associations for both PGM follow destinations to be selected.

The standard buttons allow the following associations to be edited using the generic association editing page.

<PGM1 VIDEO> allows the programme 1 video associations to be edited.

<PGM1 AUDIO> allows the programme 1 audio associations to be edited.

<PGM2 VIDEO> allows the programme 2 video associations to be edited.

<PGM2 AUDIO> allows the programme 2 audio associations to be edited.

The follow source association editor page provides the editor which allows the video or audio follow source associations for the first twenty video sources on the PGM bus to be specified for a follow destination.

Follow source associations for each of the twenty PGM bus sources can be defined as a source between 1 and 64, up to the maximum size of the local router. The ‘follow’ source number is entered and displayed next to the PGM bus source name. If, however, there is no follow source for a specific PGM bus source, it is indicated as '- -'. When this source is selected during normal operation, the follow bus will remain on the last selected source. The title of the page indicates which destinations follow sources are being edited, for example 'PGM1 VIDEO ...', or 'PGM2 AUDIO ...'.

As an example in the diagram above, for PGM 1 Video bus, sources LMS1 and LMS 3 have PGM 1 follow associations. If source 'LMS 1' is routed on the programme bus then source 'LMS 2' will be routed to the programme follow destination. If source ‘- -’ (no source) is selected as the follow source for a PGM bus source (e.g. 'LMS 2'), then when 'LMS 2' is routed on the programme bus, whatever was routed on the associated follow destination previously will remain unchanged.

To edit a source association, select the required source by using the buttons in the top left and right hand corners of the plasma display to move the focus rectangle around the screen. Once selected, the associated source can be changed using the shaft encoders below the display.

Any changes which may occur from the main control system to the follow sources are updated on the page while it is visible, with the exception of the current source which is not updated by the main control system.

The <PAGE> button is inactive, whilst the <HOME> button returns to the source setup page.

7.9 Video Path Setup

By selecting <VIDEO SETUP> from the System Configuration page, the video setup screens provide the ability to define which DSKs are present in the system, their operating mode, adding DVEs into the system and also setting the order/ position in which the DSKs, DVE and FTB functions appear in the programme path. This feature only works if the rotary switch on the 3428 card is set to dynamic control. However, the position of the Fade To Black may always be changed.

7.9.1 Configuring the DSKs

A downstream keyer (DSK) enables images such as captions and logos to be displayed on top of the programme output. There can be up to 4 keyers, which will be implemented with a software licence.

The operating mode of the downstream keyers is set via the video setup screen. This page is accessed from the system configuration page by pressing the <VIDEO SETUP> button.

Pressing the <PAGE> button, indicated with a rectangle in the bottom left hand corner of the screen, displays the Video Path Setup screen. By pressing the keys at the right hand side of the screen, <DSK 1>, <DSK 2>, <DSK 3> or <DSK 4> to toggle between Present and Not present; the system can be ‘told’ how many keyers are fitted in the vision mixer frame. It is important to set the number of keyers available to the system before going on to set the operating mode for each keyer. This operation depends on the state of the rotary switch on the 3428 module in the mixer frame.

The buttons in the top left hand corner of the screen are used to set where the Fade to black/silence is positioned when active. This can be either before or after any of the keyers in the system. A graphic showing the position of the FTB in relation to the keyers is shown alongside the Up/ Down buttons. When FTB is before DSK 1, it is positioned at the mixer output.

7.9.2 DSK Operating Mode

Once the DSKs have been configured into the system, pressing the <PAGE> button returns the plasma screen to the Video Setup screen. From here the operating mode for DSK1 to DSK4 can be set. Pressing the <DSK MODE> key for each of the keyers toggles the mode between caption <CAPTION>, effects <EFFECTS>.

In caption mode, the background signal is attenuated by the key in the caption area, and then the fill is added over the entire picture. The fill signal must be presented against a totally black background so as to avoid output in unwanted areas of the picture.

Mathematically, this is represented by the formula: Result = (1-K) x Background + Fill Where K is a factor determined by the Key and level of clip and gain.

Note: In caption mode, the clip and gain cannot be changed.

In effects mode the keyer produces a mix of the foreground and background inputs. With no key or with black as key, then output is 100% background and the foreground input is off.

Mathematically, this is represented by the formula: Result = (1-K) x Background + (K x Fill) Where K is a factor determined by the Key and level of clip and gain.

7.9.3 Selecting the Follow Mode

The follow mode acts in the same manner as the audio-over follow, following a PST/PGM video transition, a DVE move or both. The four buttons <DSK1 FOLW>

to <DSK4 FOLW> on the right of the screen are used to select the mode for each DSK.

<FOLLOW PGM> sets the DSK to follow PST/PGM video transitions only.

<FOLLOW DVE> sets the DSK to follow DVE moves only.

<FOLLOW BOTH> sets the DSK to follow either the next PST/PGM video transition or DVE move.

7.9.4 DVE Positioning in the Programme Path

The vision mixer architecture has been designed to enable the DVE to be positioned anywhere in the PGM video path.

The position of the DVE module is set in the INI file.

7.9.4.1 Dynamic Positioning

To add a DVE into the system, open the Video Setup screen by selecting the <VIDEO SETUP> button from the System Configuration screen, and then pressing the <PAGE> button, indicated with a rectangle in the bottom left hand corner of the screen.

7.10 Audio Setup

Selecting the <AUDIO SETUP> button from the System Configuration screen accesses the audio setup page. From here the audio system can be defined, in terms of number of levels, the level names right through to the audio over follow operation.

7.10.1 Levels

The <AUDIO LVLS> button allows the number of audio levels within the system to be specified. On each press of the button the number of audio levels is incremented up to a maximum of four, after which the number of levels cycles back to one.

If the number of levels has been changed, the changes do not come into effect until changes have been made and this page has been left. On exiting the page, after a change, the TX system reset page is displayed.

SYSTEM RESET

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 115

Note: Pressing the <HOME> key at any time during this process will return the screen to the audio setup page.

7.10.2 Edit Names

On pressing the <EDIT NAMES> button the operator is taken to the channel name editor. The editor only allows the number of audio levels shown on initial entry to the audio setup page to be edited.

This page allows the name of each channel to be edited on-screen. Channel names can be up to eight characters long. The characters available for the channel names are:

0123456789

ABCDEFGHIJKLMNOPQRSTUVWXYZ

abcdefghijklmnopqrstuvwxyz

space character ' '

The four shaft encoders are used to cycle through these characters for the channel names in groups of four depending on the state of the <ABC- - -/- - -ABC> button. When <ABC- - -> is selected the shaft encoders adjust the first four characters within the channel name, and when <- - -ABC> is selected the shaft encoders adjust the last four characters within the channel name.

The shaft encoders cycle through the available characters but do not wrap around to allow continual cycling, stopping on the first and last characters. Two buttons are provided to move the focus rectangle around the screen display.

The channel name that is bound by the rectangle indicates the one currently being edited. The focus rectangle wraps around the first and last channel names to allow continual cycling.

The <PAGE> button is inactive, whilst the <HOME> button returns to the audio setup page.

7.10.3 Preset Fader Position

This setting currently has no effect on the function of the TX 500.

7.10.4 Audio Over Follow

The over follow mode acts in the same manner as the DSK follow, except it follows an audio transition, DVE move or both.

Pressing the Over Follow, <OVR FOLW>, button cycles the over follow selection through the three available follow modes.

<FOLW PGM> sets the over to follow PST/PGM audio transitions only.

<FOLW DVE> sets the over to follow DVE moves only.

<FOLW BOTH> sets the over to follow either the next PST/PGM audio transition or DVE move.

The currently selected mode is shown on the button.

7.10.5 Level Break-away Cancel

Operation of the level buttons, for the PGM/ PST bus in the lower left hand corner of the panel, after a breakaway operation can be defined as either manual or automatic.

When set to <MANUL>, the level buttons remain in breakaway mode until cancelled by the operator, whereas <AUTO> cancels the breakaway, re-marrying video and audio levels, once a selection has been made on the PST or PGM bus.

The Level breakaway button provides toggle operation between manual, <MANUL>, or automatic, <AUTO> operation, with the button legend indicating the currently selected state.

7.10.6 Lead Rate

The Lead Audio function permits the audio from the currently selected source on the PST bus to be mixed with the PGM bus audio before a video transition takes place. The Lead rate, defines the time in frames that the PST bus audio will take to reach the same level as the PGM bus audio. The lead rate is set using either of the rotary encoders underneath the display, while the rate is indicated by the status bar and a numeric readout.

7.10.7 Audio Monitor Level Control

Audio monitors 1 and 2 each have independent level controls and <CUT> (no sound) and <DIM> (reduced level) buttons. Operation of these controls can be enabled or disabled by the Audio Mon Level control button.

The button provides toggle operation and, when indicating <OFF>, disables the controls preventing the output level, which is set to full, from being adjusted. Additionally, the <SPEAKER MONITORING> button is removed from the screen.

When indicating <ON> the audio monitoring controls are enabled and function as normal. The <SPEAKER MONITORING> function is also available.

7.13.1.2 Checking System Versions

On pressing the <SYS VERSN> standard button the operator is taken to the installed system software version information page. This displays the version information for the display control system, main control system and the audio mixer.

The top line indicates the overall release of the installed software. The version information is the highest release number and its associated sub-release number from all the EPROMs for which version information is available. The release is taken as a beta release if any of the EPROMs within the system are indicated as a beta release.

Each EPROM displayed has the form SPxxx/yyz, where xxx is the EPROM number, yy is the EPROM version number and z is a beta release indicating character. The beta release character is an ASCII character starting from 'A', with a space indicating a formal release of that EPROM.

Each version number has the form Vxx.yy, where xx is the release version number of the EPROM and yy is the release sub-version number of the EPROM. If the EPROM is displayed as SPXXX/XX, VXX.XX then there is no version information available, for example:

8 TX510 System configuration

8.1 Accessing the System Configuration Page

The system configuration page provides access to the system configuration options and is protected by a PIN (Personal Identification Number). This four digit number should be changed from the default setting of ‘0000’ to ensure system security. In addition, changing it periodically can help to maintain this security.

To access the system configuration page, press the <CONFG> button on the home page. The configuration access page will prompt the operator to enter a four digit PIN by pressing the appropriate buttons.

If the PIN is not entered within ten seconds, or if an invalid PIN is entered, the screen automatically reverts to the home page.

The following diagram shows the pages which are accessible from the system configuration menu. Each menu item is displayed as a unique page, although some menu items may have access to further sub-menus for selecting advanced options, for example the <SRC ASIGN> page.

<SYS SETUP> displays the 'system setup' page (section 7.13)

Pressing the <HOME> button, from any of these pages will return you to the system configuration page, while pressing it from the system configuration page returns to the home page.

8.2 Changing the Configuration Page PIN

From the system configuration page, select the <PIN SETUP> button to display the Change configuration PIN screen. The system PIN is 4 digits long and prevents unauthorised access to system configuration settings.

The text ‘Enter Pin’ followed by four hyphens prompts the user to enter a new PIN. After entering the 4th digit, the text ‘Verify PIN’ is displayed, prompting the user to re-enter the new PIN to verify it. As the new PIN is entered, and verified, the hyphens are replaced with asterisks indicating that the button presses have been read.

If the new and verify PINs match, the change configuration screen is closed, and the display returns to the system configuration page.

If the new and verify PINs do not match, the page is redrawn to its initial state, allowing the operator to retry the operation.

The <HOME> button returns to the system configuration page without affecting the currently selected PIN.

8.3 Transition Rates

To access this page from the system configuration page, press the <TRANS RATES> button.

This page allows the system transition rates to be modified, and set, and also enables flip-flop operation of the PGM bus to be activated

Masterpiece User Manual snellgroup.com

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 128

The <HOME> button returns the display to the system configuration page.

8.3.1 Changing the Transition Rates

The transition rate setup page allows the three transition rates for the system to be adjusted and set. These three rates, <SLOW>, <MED> and <FAST> determine the rate a PST/PGM transition occurs at, and are recalled by selecting a transition rate button from the bottom left hand corner of the control panel.

Each of the three current settings is shown on the left of the screen, as the number of frames over which the transition will occur, in the relevant button.

The default settings are:

fast = 12 frames

medium = 25 frames

slow = 50 frames

To adjust each rate, select the required rate button. The currently selected button is shown with inverse text. The selected transition, and current rate, is shown below the rate bar in the centre of the screen

The rate is adjusted by using either shaft encoder below the rate bar. Turning the shaft encoder clockwise increases the number of frames, while turning it anti-clockwise decreases the value.

The bar, numeric value beneath it and the rate button all reflect the changes being made, however these new settings will not take effect until they have been saved. To save the new settings, press the <Save> button in the top right corner of the screen. This saves the new settings.

8.3.2 Configuring ‘flip-flop’ For Transitions

The <Flip Flop> button on the right hand side of the transition rates page can be toggled to enable (button highlighted) or disable (button not highlighted) flip-flop operation.

Flip-flop mode, when activated, swaps the PST and PGM sources at the end of a PGM bus transition.

Note: When using the TX 510 with Snell automation systems, it is important to ensure that Flip Flop mode is NOT active as the action of selecting sources on the PST bus inserts manual events into the schedule.

8.4 Configuring Fade to Black Options

In addition to the ability to define the fade rate for the fade to black/ silence, when using the ICON vision mixer, the fade to black function can be changed to be fade to colour. Pressing the <FTB> button on the system configuration page opens the fade to black page.

8.4.1 Fade to Black Rate

Either shaft encoder below the display adjusts the fade rate, which is displayed in frames. The possible range of values is between 0 and 99 frames, where 0 = cut.

Changes being made to the fade to black rate are displayed on the bar, and the numeric value beneath it. These changes are automatically saved as they are modified.

With the ICON vision mixer, the fade to black function can be positioned either before or after any of the keyers in the video path.

Pressing the <HOME> button returns the display to the system configuration page, saving any changes.

8.4.2 FTB Colour selection

This is not implemented in the Masterpiece Mixer.

Pressing the <FTB COLOR> button provides the ability to set the TX 510 to fade to a colour rather than to black. Colours available are Black, Red, Green or Purple and are selected by using the <COLOR UP> and <COLOR DOWN> buttons.

Pressing the <HOME> button returns the display to the system configuration page, saving any changes that have been made.

8.5 Setting Up the Panel

Settings for general panel operation can be changed from the Panel Setup page. To access this page, press the <PANEL SETUP> button on the system configuration page.

8.5.1 Level Break-away Cancel

Operation of the level buttons, for the PGM/ PST bus in the lower left hand corner of the panel, after a breakaway operation can be defined as either manual or automatic.

When set to <MANUL>, the level buttons remain in breakaway mode until cancelled by the operator, whereas <AUTO> cancels the breakaway, re-marrying video and audio levels, once a selection has been made on the PST or PGM bus.

The Level breakaway button provides toggle operation between manual, <MANUL>, or automatic, <AUTO> operation, with the button legend indicating the currently selected state.

8.5.2 Audio Monitoring

A single, controllable, audio monitoring output is provided with the TX 510. This section of the panel has a level control plus <CUT> (no sound) and <DIM> (reduced level) buttons to adjust the output level. Operation of these controls can be enabled or disabled by the Audio Mon Level control button.

The button provides toggle operation and, when indicating <OFF>, disables the controls preventing the output level, which is set to full, from being adjusted. Additionally, the <SPEAKER MONITORING> button is removed from the screen.

When indicating <ON> the audio monitoring controls are enabled and function as normal. The <SPEAKER MONITORING> function is also available.

8.5.3 Speaker Monitoring

The speaker monitoring function sets the operation of the <CUT> and <DIM> speaker monitoring buttons. When set to <DIM>, the buttons operate as <CUT> and <DIM> buttons exclusively, where <CUT> represents a complete silence in the audio and <DIM> represents a 12dB reduction in the level. When set to <CUT R> the <DIM> button operates as a cut right with <CUT> being cut left and the buttons no longer operate mutually exclusively.

8.5.4 Stop Watch Mode

The button <TOD> / <TIMER> provides toggle operation, allowing either stop watch mode or segment/remaining timer mode to be available on the timer home page. The button legend displays the current state, either TOD or Timer.

8.5.5 Key Functions

There are two key functions <KEY FNS> buttons on this screen. These buttons, in conjunction with internal control panel cabling, enable the function of two groups of buttons in the top left corner of the panel to be specified. The function control, and the buttons they relate to on the panel is as detailed in the diagram below.

8.6.1 Router Configuration

Selecting the <ROUTE CONFG> button provides access to the Router Configuration screen, where the router control options offered by the TX 510 can be set.

Three control modes are available; 'local', 'external – fixed' and 'external - auto'. The currently selected mode is shown using inverse text on the button. Once the router type has been configured, pressing the <HOME> button returns the display to the Source setup page.

‘<Local>’ control mode, in this case, refers to any router under direct control of the TX Series controller using Snell general switcher protocol (SW-P-02). The router will be a separate framed router such as Sirius or Freeway connected via the Ext Rtr (Aurora) port on the TX Series controller.

'<EXT FIXED>' and '<EXT AUTO>' should be selected for systems where the TX Series controller uses an external controller, such as Aurora, for router control and to assign sources to the system.

The Aurora <EXT FIXED>/ Automation <EXT AUTO> interface

For external router control via an Aurora controller to operate, the router configuration page must be set for either '<EXT FIXED>' or '<EXT AUTO>'. In addition, the physical link between the Aurora and TX Series controller is via a single RS-422 link between the TX 510 controller, Ext Rtr port, and a panel port on the controller.

The TX 510 emulates 2 Multi-drop panels on this port, at the first and second positions. The panel type used is ‘Master Control’ and each panel should be configured with a different suite number (refer to the control system documentation for further details). The first panel is used to control the Video crosspoints (PGM, PST and AUX 1), while the second panel is used for Audio crosspoints (PGM,

PST, AUX 1 and Over).

Note: If dedicated overs are used the last destination, over, is not required. This interface then operates in one of two modes as follows.

8.6.1.1 Mode 1 - <Ext-FIXED>

In this mode all assignments to channels are made separately using a channel assignment panel connected to one of the panel ports on the Aurora controller. This panel should be configured to use video and audio panels with the same suite numbers as the ‘pres panel’. Any assignment to channels made from this panel will then be reflected on the TX 510.

8.6.1.2 Mode 2 - <Ext Auto>

In this mode the assignments to the channels are set as described for the Ext Fixed mode, via a channel assignment panel, however they are not fixed. The TX 510 will assign a source to a channel, if the source requested on the automation port is not currently assigned to the panel.

When a command to set a channel, on a bus is received from the automation port, the channel number is assumed to be equal to the association number on Aurora. This source association number is assigned to a channel. The video and audio suites are expected to have the same panel assigned and will always have the same source association assigned for both video and audio.

When a source is requested via the automation port, the TX 510 will check the source association against those sent by the system controller and if found, the matching channel will be used. If it is not found, then the highest unused channel will be assigned that source association. The maximum number of channels that can be automatically assigned is 8 (channels 5 to 12). These sources are assigned from the right hand side of the mixer bus.

It is also possible for the automation system to remotely assign source associations to channels, this is detailed in SW-P-32 (Automation Control Protocol).

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 136

8.6.1.3 Local Route

The <LOCAL ROUTE> button is only visible on systems set to operate with a ‘Local’ router.

From this screen, the communication link between the controller and ‘local’ router can be specified. This can be set using the <RS232> or <RS422> buttons.

The third button on the screen allows the local router type to be defined. The button toggles between the two options, <TM24> and <HD16>, enabling the switcher to operate with either a 24 or 16-input router. This feature permits the system to be configured as an SD system, using a 24-input router, <TM24>, or an HDTV system using a 16-input router, <HD16>.

By defining a router type, sources are ‘mapped’ according to the router size, to the correct buttons on the panel. The 24-input router uses inputs 1-12 for the prime sources and 21-24 as the additional four Aux bus sources, while with a 16-input router, no mapping is required.

8.6.2 Source Names

Selecting the <SRC NAME> button from the Source Setup page opens the Source Names screen.

From this screen the system can be configured to use either local, <LOCAL>, or external <EXT AUTO> source names. The currently selected option is shown as inverse text. Pressing the <HOME> button returns the screen to the Source Setup page.

These characters do not wrap around, but stop on the first and last characters.

As each source name is edited the change can be seen within the associated four character source name display between the PGM and PST busses. Each source name is four characters long and is numbered (1-12).

The <HOME> button returns the display to the source setup page.

8.6.4 VTR Sources

The <VTR SRCS> button opens the VTR control sources editor page.

This page enables RS 422 router inputs (VTR control sources) to be associated with PGM/ PST bus sources.

The Machine Control port should be cabled to the router as follows;

TX/RX1 - Controls the machine on the PST bus, TX/RX2 - The Aux1/2 machine and TX/RX3 - provide the RS422 router control to its remote control port.

In the diagram above, VTR1 is connected to source (input) 15 of the RS-422 router

while the output is connected to the TX Series controller. The screenshot at the beginning of this section shows VTR 1 (source 15) is associated with the PGM/ PST bus source which is labelled 'VTR1'. When VTR 1 is selected on the PST bus, source 15 on the RS 422 router will be connected to the TX Series controller.

To edit the VTR control source for an input, select the required source by touching the screen. The source is then bound by a rectangle, and changed using the shaft encoders below the display. The VTR control source is displayed next to the input name, where '- -' indicates no VTR source and numbers in the range 1 to 64 indicate the RS-422 router source number. The same RS-422 source can be used with more than one mixer source.

The <HOME> button returns the display to the source setup page.

8.6.5 VTR Destinations

On pressing the <VTR DEST> button the operator is taken to the VTR control destination editor page.

This page enables RS-422 router destinations to be assigned, as controllable destinations, for the Preset and Aux busses. When a VTR is to be controlled, the VTR control source number is routed to the required destination on the RS-422 router making the duplex link from which the VTR can be controlled. The controlled destination depends on which router bus is in use.

The VTR control destination is displayed on a single line with ‘- -’ indicating no VTR control destination or a number in the range 1 to 64 indicating the RS-422 router destination number.

The left hand shaft encoder controls the Preset destination, while the right hand shaft encoder is used to configure the destination for the Aux bus. Once a destination number has been modified, an <UPDATE> button appears above the <HOME> button. Pressing <UPDATE> accepts any changes that have been

made.

If only one destination is set, or if the same router destination is assigned to both the preset and Aux destinations, a warning ‘Invalid destinations’ is displayed on the screen. When in this state, pressing <UPDATE> will have no effect.

The <HOME> button returns the display to the source setup page.

M/C control port 1 = PST, port 2 = Aux 1 or 2, port 3 = RS422 router control.

8.6.6 Pre-roll

On pressing the <PRE ROLL> button the operator is taken to the source pre-roll editor page.

To edit the pre-roll time for a source, select the required source by pressing it on the touch screen. The selected source is then bound by a rectangle. The pre-roll time is displayed in seconds between 0 and 62, and is modified using the shaft encoders below the display.

Where ‘- -’ is displayed, it indicates no pre-roll for the channel. i.e. A pre-roll command will not be sent on the Preset port for the <ROLL> and <PRE-ROLL/ TAKE> buttons.

The <HOME> button returns the display to the source setup page.

8.6.7 Router Destinations

Pressing the <ROUTE DEST> button opens the Local router destinations top page. From here, the Video and Audio router destinations of the local router can be selected and assigned to the TX System.

The video and audio pages allow the local router destinations to be assigned to the PGM, PST, AUX,

Over (audio) and PGM follow busses. For systems where a system controller provides the interface between the TX system and router, changing these settings will have no effect on system operation, except audio over, where ‘- -’ indicates the use of dedicated audio over inputs, and ‘NN’ specifies the destination number for routed audio over inputs.

The local router destination is displayed next to the bus name as a number in the range 1 to 64 or a ‘- -’ indicating there is no destination assigned to the bus.

To edit the destination number for one of the controlled busses, touch the required bus on the screen to select it. The selected bus is then bound by a rectangle and the destination number displayed alongside the bus name can be changed by using either of the shaft encoders below the display.

The range of values selected/ displayed may 'jump' or miss destination numbers as

snellgroup.com Masterpiece User Manual

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 141

the system does not allow the same destination to be specified more than once. The destinations specified must include any offsets required to ‘stack’ the commands down a single RS-422 port, enabling separate video and audio destination numbers to be selected.

The following diagrams show typical router destination numbers for a system with an SDV and AES router configured as TX Series levels.

The <HOME> button returns the display to the source setup page.

8.7 PGM Follow

The TX Series provides a programme follow facility, for use with systems using Local routing, allowing up to two, video/ audio, router outputs to ‘follow’ the main PGM bus.

These additional busses, PGM 1 and 2 provide cuts only transitions and can be used as a ‘shadow’ output for the PGM bus. These can be fed into an emergency/ bypass switcher, or be used to provide ‘clean’ outputs for recording, or other as regional feeds. For these to operate correctly, each bus should be assigned a destination number to control and source associations to select.

Source associations can be set for each ‘follow’ bus, with independent control over video and audio (providing all audio levels in multi-level systems are married) outputs, enabling PGM breakaways to be achieved.

From the source setup page, pressing the <PGM FOL’W> button takes the operator to the video and audio PGM follow associations editor main page. This page enables the video and audio follow source associations for both PGM follow destinations to be selected.

Selecting the required PGM follow button opens the relevant follow association editor page.

Page 142: MASTERPIECE USER MANUAL - grassvalley.com Branding and... · Masterpiece User Manual snellgroup.com Masterpiece User Manual Issue 8 Rev 2 ...

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 142

<PGM1 VIDEO> allows the programme 1 video associations to be edited.

<PGM1 AUDIO> allows the programme 1 audio associations to be edited.

<PGM2 VIDEO> allows the programme 2 video associations to be edited.

<PGM2 AUDIO> allows the programme 2 audio associations to be edited.

After selecting the association editor page, the title of the page indicates which destination follow sources are being edited, for example 'PGM1 VIDEO ...', or 'PGM2 AUDIO ...'.

Follow source associations for each of the twelve PGM bus sources can be defined as a source between 1 and 64, up to the maximum size of the local router. The ‘follow’ source number is entered and displayed next to the PGM bus source name. If, however, there is no follow source for a specific PGM bus source, it is indicated as ‘- -’. When this source is selected during normal operation, the follow bus will remain on the last selected source.

As an example in the diagram above, for PGM 1 Video bus, sources VTR1 to VTR3 have PGM 1 follow associations. If source 'VTR1' is routed on the programme bus then source '14' will be routed to the programme follow

destination. If source ‘- -’ (no source) is selected as the follow source for a PGM bus source (e.g. 'SVR1'), then when 'SVR1' is routed on the programme bus, whatever was routed on the associated follow destination previously will remain unchanged.

To edit a source association, select the required source by pressing it on the touch screen. The selected source is then bound by a rectangle. The associated source can then be changed using the shaft encoders below the display.

The <HOME> button returns to the PGM follow associations page.

8.8 Video Path Setup

By selecting <VIDEO SETUP> from the System Configuration page, the video path setup screens provide the ability to define which DSKs are present in the system, their operating mode, adding DVEs into the system. In addition the order/ position in which the DSKs, DVE and FTB functions appear in the programme path can be set.

8.8.1 Configuring the DSKs

A downstream keyer (DSK) enables images such as captions and logos to be displayed on top of the programme. The TX 510 can be configured to control up to two DSK cards in the vision mixer frame. The operating mode of the downstream keyers is set via the video setup screen. This page is accessed from the system configuration page by pressing the <VIDEO SETUP> button.

8.8.2 DSK Operating Mode

Selecting <VIDEO SETUP> returns the screen to the Video Setup page, where the <MODE> key for each keyer toggles its operational mode between caption <CAPTN> and effects <FX>. The current status is shown on the screen under the heading ‘Mode’, alongside the keyer. If the keyer has been removed, the mode is set to N/A, indicating that it is not available.

Page 144: MASTERPIECE USER MANUAL - grassvalley.com Branding and... · Masterpiece User Manual snellgroup.com Masterpiece User Manual Issue 8 Rev 2 ...

Masterpiece User Manual snellgroup.com

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 144

In caption mode, the background signal is attenuated by the key in the caption area, and then the fill is added over the entire picture. The fill signal must be presented against a totally black background in order to avoid output in unwanted areas of the picture. There is no control of clip and gain in caption mode.

In effects mode the keyer produces a mix of the foreground and background inputs. With no key or with black as key, then output is 100% background and the foreground input is off.

8.8.3 Selecting the Follow Mode

The follow mode allows each keyer to be set to follow a PST/PGM video transition, a DVE move or both. The <FOLLW> buttons associated with each DSK are used to select the mode for each DSK.

<FOLLOW PGM> sets the DSK to follow PST/PGM video transitions only.

<FOLLOW DVE> sets the DSK to follow DVE moves only.

<FOLLOW BOTH> sets the DSK to follow either the next PST/PGM video transition or DVE move.

As with the Keyer mode, the current status is shown on the screen under the heading ‘Follow’, alongside the relevant keyer.

Adding and removing keyers from the system

The default, and maximum, number of keyers available with the TX 510 is two. To add, or remove keyers, press the <VIDEO ORDER> button to access the Video path setup screen. The diagram shows which keyers are currently configured within the system.

Pressing the <DSK 1 IN/OUT> and <DSK 2 IN/OUT> buttons in the bottom left hand corner of the screen, to toggle between DSK In and DSK Out, the system can be ‘told’ how many keyers are fitted in the vision mixer frame. When the keyers appear in the diagram, they are configured into the system, and pressing the <DSK X OUT> button removes the keyer from the system. The button label then changes to be <DSK X IN>.

Note: Removing DSK 1 from a system where two keyers have been configured in circuit effectively removes both keyers.

It is important to set the number of keyers available to the system before defining the operating mode for each keyer.

Once the DSKs have been configured into the system, pressing the <HOME> button returns the screen to the System Configuration screen.

8.8.4 Configuring the DVE

To add a DVE into the system, open the Video Setup screen by selecting the <VIDEO SETUP> button from the System Configuration screen, then press the <VIDEO ORDER> button.

Page 145: MASTERPIECE USER MANUAL - grassvalley.com Branding and... · Masterpiece User Manual snellgroup.com Masterpiece User Manual Issue 8 Rev 2 ...

snellgroup.com Masterpiece User Manual

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 145

Pressing the <DVE ADD> key places the DVE after the last keyer in the system.

Note: It is recommended that the number of keyers available to the system is set before going on to configure the DVE position, as adding or removing keyers may cause the DVE to be removed from the circuit.

Once the DVE appears in the system mimic diagram, it can be moved up and down in the programme chain by using the <DVE UP> and <DVE DOWN> keys.

Page 146: MASTERPIECE USER MANUAL - grassvalley.com Branding and... · Masterpiece User Manual snellgroup.com Masterpiece User Manual Issue 8 Rev 2 ...

Masterpiece User Manual snellgroup.com

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 146

With the DVE at the end of the chain, it can be removed by pressing <DVE OUT>, and subsequently hidden by selecting <DVE HIDE>.

8.8.4.1 Fade to Black (FTB) Position

The buttons on the left hand side of the screen are used to define where the Fade to black/silence function is positioned when active, and can be either before or after any of the keyers in the system. The diagram to the right of the buttons changes to provide a visual indication of the position of the FTB function in relation to the keyers. When FTB is before

DSK 1, it is positioned on the PGM/ PST mixer output.

8.9 Audio Setup

Selecting the <AUDIO SETUP> button from the System Configuration screen accesses the audio setup page. From here the audio system can be defined, in terms of number of levels, the level names right through to the audio over follow operation.

8.9.1 Preset Fader Position

Pressing the <PST FDR> button toggles the preset fader position between <POST> and <PRE>. The current selection is displayed on the button.

When set to <PRE>, the PST bus fader is located with the PGM bus fader - before the Audio Over fader. This is the normal operational mode as any audio from the PST and / or PGM bus contributing to the PGM output will have its gain reduced as the result of an audio over being taken to air.

If the Preset fader position is set to <POST>, the PST bus fader is positioned after the audio over fader. When configured in this way, the PST bus, when contributing

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 148

to the main output, for example during a mix transition will be at full level.

8.9.2 Audio Over Follow

The over follow mode acts in the same manner as the DSK follow, except it follows an audio transition, DVE move or both.

Pressing the Over Follow, <OVR FLW>, button cycles the over follow selection through the three available follow modes.

<FOLW PGM> sets the over to follow PST/PGM audio transitions only.

<FOLW DVE> sets the over to follow DVE moves only.

<FOLW BOTH> sets the over to follow either the next PST/PGM audio transition or DVE move.

The currently selected mode is shown on the button.

8.9.3 Levels

The audio levels button, shown as <1 LVL> in the example screen shot below, allows the number of audio levels within the system to be specified. On each press of the button, the number of audio levels is incremented up to a maximum of four, after which the number of levels returns back to one.

If the number of levels has been changed, these changes do not come into effect until this page has been left, by pressing the <HOME> button. On exiting the page, after a change, the TX 510 system reset page is displayed.

After pressing the <RESET> button, there is a 10 second countdown in which to accept the change by pressing the <CONFM> button.

snellgroup.com Masterpiece User Manual

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 149

Once the system has been reset, the user is notified that the system has been reset and it indicates the number of audio levels now in the system. This example is for a system with two audio levels.

Note: Pressing the <HOME> key at any time during this process will return the display to the System Configuration screen.

8.9.4 Edit Names

On pressing the <EDIT NAMES> button the operator is taken to the channel name editor page. This page allows the channel names to be edited. The editor only allows the number of audio levels shown on initial entry to the audio setup page to be edited. The example below shows the names for an eight channel (4 level stereo) audio system.

This page provides the channel name editor, which allows the name of each channel to be edited on-screen.

Masterpiece User Manual Issue 8 Rev 2 © 2013 Snell Limited Page 150

To edit a channel name, select the required channel by touching it on the screen. The selected channel is bound by a rectangle and the first letter of the name has an underscore indicating which letter is currently being edited. The left hand shaft encoder is used to select the letter to be edited, while the right hand one is used to change the character.

The characters available for the source names are:

Space character ' '

0123456789

ABCDEFGHIJKLMNOPQRSTUVWXYZ

abcdefghijklmnopqrstuvwxyz

These characters do not wrap around, but stop on the first and last characters.

The <HOME> button returns the display to the source setup page.

8.9.5 Lead Rate

The Lead Audio function permits the audio from the currently selected source on the PST bus to be mixed with the PGM bus audio before a video transition takes place. The Lead rate, defines the time in frames that the PST bus audio will take to reach the same level as the PGM bus audio. The lead rate is set using either of the rotary encoders underneath the display, while the rate is indicated by the status bar and a numeric readout.

9 Configuring the GPIs

9.1 Changing GPI Assignment

The TX Series provides 32 GPI outputs as standard. Each GPI can be configured to be a channel, pre roll or a row cue. This page can be accessed by pressing the <GPI CONFG> button from the system configuration page.

To edit the function of a GPI, select the required channel by touching it on the screen. The selected channel is bound by a rectangle. As there are a total of 32 output GPI’s, spread across seven pages, that can be configured from this editor, it may be necessary to use the page <UP> and <DOWN> buttons to locate the required GPI.

Using the left hand shaft encoder below the display scroll through the available options, channel cue, row cue, pre-roll & unused, until the required function is shown. The right hand shaft encoder can then be used to change the value associated with the GPI, i.e. source number, bus name etc. The following table details the GPI function and available assignment values.

GPI function (Left shaft encoder)

GPI assignment (Right shaft encoder)

Channel cue Input channel, 1-12 refer to the main sources, and 21-24 to the 4 audio-overs

Row cue PGM video, PGM audio, PST video, PST audio and Over

Pre-roll Select an input channel, 1-12, to assign the pre-roll to. This function operates in conjunction with the channel pre-roll time setting (see section 8.6.6) and is used to start machines that require a GPI start trigger.

The top line indicates the overall release of the installed software. The version information is the highest release number and its associated sub-release number from all the EPROMs for which version information is available. The release is taken as a beta release if any of the EPROMs within the system are indicated as a beta release.

Each EPROM displayed has the form SPxxx/yyz, where xxx is the EPROM number, yy is the EPROM version number and z is a beta release indicating character. The beta release character is an ASCII character starting from 'A', with a space indicating a formal release of that EPROM.

Each version number has the form Vxx.yy, where xx is the release version number of the EPROM and yy is the release sub-version number of the EPROM. If the EPROM is displayed as SPXXX/XX, VXX.XX then there is no version information available.

Note: The screen shot shown above does not represent the latest code versions.

11 Appendix 1: Audio Mixer tables

Each level of the audio mixer can mix together the programme and preset audio inputs on a number of channels – usually a stereo pair: left and right. The resulting admixture is both put out as the clean feed and is the input to the voice over sub-system. The voice over sub-system combines the clean feed with a number of voice over inputs. The output of the voice over sub-system is passed through a fade to silence unit before being emitted as programme output.

At each stage in the audio processing, the amplitude of each audio signal is multiplied by three factors: gain in the range -12 dB to +12 dB (approximately 0.25 to 4.0 absolute), level in the range 0.0 to 1.0, and phase invert which is either -1.0 or +1.0.

Combined gain, level and phase invert function.

Over 2

Over 1

Preset

Programme

Over 4

Clean feed

In every case, the value of gain defaults to 0 dB (0.0 absolute) and the value of phase invert defaults to +1.0. The default value of level is 1.0 for the programme input and output, but is 0.0 for the preset input, the over inputs and preview inputs.

All instances of gain, level and phase invert values can be initialised to alternative values by settings in the audio initialisation file and some instances can be updated via commands from a control system which derives required values from a control console, a fader panel or an automation system.

The audio mixer can smoothly change the value of level; this is done to fade inputs in and out.

The value of level is designed to control loudness rather than absolute amplitude. Because of the physiological and psychological aspects of human auditory perception, the perceived loudness of sound is not simply proportional to the amplitude of the sound. Loudness is perceived as being, to a first approximation, proportional to the log of the amplitude.

The audio mixer converts level values of loudness to absolute multiplier values by means of a look-up table. In order to ensure flexibility of the audio mixer, a number of different tables are available. These are illustrated below:

Note: In these tables the y-axis is scaled from 0 to 70,000 reflecting the internal values used by the system.

The default look-up table used for the programme and preset inputs is table 3: fader law. This lies partway between the linear and fully logarithmic tables.

In a cross fade, the value of level for programme input varies smoothly from 1.0 to 0.0 and, similarly, the value of level for preset input varies smoothly from 0.0 to 1.0. The effect on the absolute amplitude of the programme and preset inputs is illustrated below. Note how a simple arithmetic sum of the amplitudes shows a distinct dip.

The magnitude of the mid-fade dip may be reduced by selecting a look-up table that is more nearly linear (e.g. tables 0, 1 or 2); alternatively, the depth of the dip may be increased by selecting a look-up table that is more nearly logarithmic (e.g. tables 4, 5 or 6).

The look-up table can be changed by settings in the audio initialisation file. For example, to select look-up table 2 for audio level 1 programme and preset:

level 1 programme left table = 2

right table = 2

preset left table = 2

right table = 2

If it is desired to do so, it is possible to choose look-up tables that sum to more than one. These are the inverse look-up tables (e.g. tables 7, 8, 9, 10, 11 and 12). Use of the inverse of the standard fader law (table 9) is illustrated bellow. The magnitude of the mid-fade hump may be reduced by selecting a more nearly linear look-up table or increased by selecting a more nearly logarithmic look-up table.

The default look-up table used for the voice over inputs and for the fade to silence is a logarithmic look-up table in the range –40 dB to 0 dB (table 14). The look-up table selection can be changed in the audio initialisation file. Tables 6 and 13 provide a logarithmic look-up in the range –80 dB to 0 dB and –60 dB to 0 dB respectively. All the logarithmic tables include a small linear portion near zero to ensure that zero values of level are mapped to a zero absolute multiplier.
