1 ASD-231i NTSC/PAL to 4:2:2 Adaptive Decoder with TBC 1.1 Introduction

The ASD-231i is a multi-standard, fully digital, 12-bit decoder with 3D and 2D adaptive decoding capabilities allowing optimal picture quality with virtually no cross-color or cross-luma artifacts. A built-in Time-Base Corrector (TBC) supports unstable (VHS) inputs. The TBC mode offers an auto decoding filter selection which automatically switches between comb and bandsplit filtering on the luminance path only. The ASD-231i offers the possibility of connecting a reference input for complete studio integration; it synchronizes serial 4:2:2 video to a local reference input. If no external reference is detected, the ASD-231i locks on to the composite input. If the input signal degrades or disappears, the ASD-231i can be set to freeze on the last error-free field, switch to black, or disable the output 4:2:2 signals. For those audio users requiring video delay tracking, a video processing delay signal provides the ASD-231i input-output delay at all times. The ASD-231i, with its built-in frame synchronizer and Automatic Gain Control supports stable, unstable, and satellite inputs. All four 4:2:2 serial digital video signals respect the SMPTE 259M-C standard. Also, the serial digital video outputs carry EDH data according to the SMPTE RP165 standard. Additionnally, the ASD-231i has a built-in color bars test signal. The ASD-231i is a member of the imaging family of digital video modules and therefore requires the imaging Quartet, imaging Symphonie, or imaging Solo frame for mounting and power.

2.4 ASD-231i Electrical Installation

When connecting the ASD-231i to external equipment, make sure that all serial digital connections are point-to-point. For instance, there must be a point-to-point connection between a 4:2:2 OUT BNC and target equipment. If a T-connector is used to connect other equipment, the maximum specified cable length is no longer valid. Make sure the output cables have maximum lengths of 250 m (850') each.

COMPOSITE IN - composite video with passive loop-through Connect a NTSC, PAL, PAL-M, PAL-N, or SECAM composite video source to COMPOSITE

IN. Refer to Figure 2.2. NTSC signals must conform to the SMPTE 170M standard; PAL (625/50), PAL-M (525/60), PAL-N (625/50), and SECAM (625/50) signals must conform to the ITU (CCIR) 624-4 standard.

If the loop-through output is not used, terminate it with a 75 ohm termination.

REF IN - reference input with passive loop through If you wish to reference the ASD-231i to the rest of your facilities, connect a studio reference

signal to the BNC labeled REF IN. The ASD-231i accepts SMPTE 170M/PAL ITU 624-4 or 2 Vpp/4 Vpp composite sync reference signals. Refer to Figure 2.2.

When using the Quartet, Quartet-C, Solo or Symphonie-R-C, the ASD-231i provides a loop

through output of the studio reference signal. Make sure to terminate this output with a 75 ohms terminator when it is not being used.

A valid analog composite reference signal will turn on the REF indicator located on the

module’s front end. The reference signal must be NTSC for 60 Hz sources (NTSC and PAL-M) and PAL for 50 Hz sources (PAL, PAL-N, and SECAM). If there exists a line format mismatch between the reference input and the composite input, the REF indicator flashes.

4:2:2 OUT 1, 2, 3 and 4 - serial digital video outputs The ASD-231i provides 4 video output BNCs. These BNCs, labeled 4:2:2 OUT 1, 2, 3 and 4,

provide the decoded video signal conforming to the SMPTE 259M-C standard. Delay – video processing delay signal When using a Quartet-M, -M-A75, -M-A110 or Symphonie-R-M, the ASD-231i provides a

video processing delay signal through an RJ-45 connector using RS-422A transport standard. This signal may be used by an audio processor to avoid lip sync problems. Connector pinout is detailed on Figure 2.3.

Figure 3.1 illustrates the ASD-231i's user interface situated at the front end of the module. The interface components include the following: • 4-character dot matrix display and 4 push-buttons for menu access • Input status monitoring: reference and composite source signals • Source Type selection • Test pattern selection

Figure 3.1 ASD-221i user interface

3.2 Menu Introduction

Most ASD-231i parameters are accessed and changed via an easy-to-use menu. The flow chart of Figure 3.2 outlines the entire ASD-231i menu path. The menu consists of 11 major functions: format, filter, timing, gain, setup, hue, freeze mode, vertical ancillary mode, CC, true PAL filtering, and factory reset. Each menu is described throughout this section. The following items should be remembered when accessing the menu. Normal Mode When the menu is not being accessed we refer to this as normal mode. When in normal mode, the current format loaded by the ASD-231i is displayed and the display is dimmed. Navigating Through the Menu The front panel push-buttons are used to navigate the menu of Figure 3.2. The following describes the function of each push-button when navigating through the menu. +: Press + to move down in the menu or to increase the parameter value. For example,

if you are currently at GAIN-BRI, pressing + will scroll downwards through the

selections SAT and ALL. Depressing + during an adjustment will increase the parameter value at a faster rate.

-: Press - to move up in the menu or to decrease the parameter value. For example, if

you are currently at TIMG-HOR, pressing - will scroll upwards to the selection VERT. Depressing - during an adjustment will decrease the parameter value at a faster rate.

SELECT: Changes to a menu parameter are stored immediately to non-volatile memory. For

example, after the desired setup has been set, press SELECT. The menu returns to STUP and the new setup value is stored for the current format.

ESC: If ESC is pressed after making changes to a parameter, the parameter is reset to the

value it had prior to the change. For example, after changing the brightness, press ESC. The menu is returned to BRI and the previous brightness gain is reloaded.

Automatic Exit From Menu After 1-Minute Interval If the menu is currently being accessed and no push-button has been pressed for 1 minute, the ASD-231i automatically exits from the menu thereby returning to normal mode. Also, changes made to the current parameter will be stored.

3.3 Input Status Monitoring

REF The REF LED turns on to indicate a valid composite signal has been detected on the REF IN BNC. It will remain off if no reference signal is installed. If there exists a line format mismatch between the reference input and the composite input, the REF LED flashes. To avoid this situation, make sure both the reference and source signals are 525 (60Hz) lines or 625 (50 Hz) lines. IN ERR The IN ERR (error) LED will turn on if no composite input signal is installed. Also, if a standard is forced, for example, NTSC and the input signal detected is other than a NTSC signal, the IN ERR LED will indicate an error. Make sure the source signal is properly connected to COMPOSITE IN and verify for any source equipment errors. It is highly recommended to enable black & white input detection when working with monochrome signals. Refer to section 3.5, Input Format Detection.

3.4 Source Type Selection

The ASD-231i accepts three different types of sources: STUDIO, SATELLITE and VCR. Select STUDIO sosurce type when using high quality sources, SATELLITE for satellite sources, and VCR for unstable sources.

Changes to the input modes can only be made when in normal mode. Therefore, make sure you have left the menu. Press the DOWN(-) push-button to scan through the available selections. The selected source type turns on the appropriate LED. N.B.: There is no STUDIO option available during SECAM operation.

3.5 Input Format Detection

The ASD-231i supports two modes of format detection: automatic input format detection and forced input format selection. Automatic Format Detection During this mode of detection, the ASD-231i detects the type of input and automatically switches to that format by loading the decoder with the format’s parameters. To enable automatic input detection follow these steps: 1. Press SELECT to enter the menu. FRMT is displayed. 2. Press SELECT to enter the FRMT menu. The current format is displayed. 3. To set automatic detection, press the UP(+) or DOWN(-) push-button until AUTO is

displayed. 4. Press SELECT to store automatic input detection. FRMT is displayed. 5. To enable automatic input detection and return to normal mode, press ESCAPE. NOTE: During automatic input detection, if the input signal changes while you are attempting to change the value of a menu function, the ASD-231i exits from the menu, returns to normal and attempts to locate the correct format. However, this feature is disabled only when the FRMT menu is being accessed.

13

Forced Input Format Selection This mode allows you to select one of the input formats. During this mode of operation, the ASD-231i remains configured with the format selected at all times regardless of the input signal’s format. If the input signal’s format is other than that selected, the IN LED will turn on. This feature is handy when you are certain that the input format will not change. To select the forced input for forced input detection, follow these steps: 1. Press SELECT to enter the menu. FRMT is displayed. 2. Press SELECT to enter the FRMT menu. The current format is displayed. 3. To force an input format, use the UP(+) or DOWN(-) push-button to select between NTSC,

PAL, PALM (PAL-M), PALN (PAL-N), SECM (SECAM), and BW (monochrome). 4. Press SELECT to store the new forced input selection. FRMT is displayed. 5. To return to normal mode, press ESCAPE.

Monochrome Input Signal When working with monochrome input signals, set the FRMT menu to BW to accept a black and white input. Selecting BW forces the ASD-231i to disable decoding of the input signal. During BW mode, automatic detection is made between 525- and 625-line formats. Detecting a 525-line format signal will load the NTSC format and a 625-line format will load the PAL format.

3.6 Decoding Filter

The ASD-231i provides the 5 types of decoding filters which are listed in Table 3.1. The selection of a decoding filter will depend highly on the nature of the input composite signal. For example, choosing between A-3D and A-2D will depend highly on the content of your source. Most artifacts will disappear with A-3D but a ghosting effect may appear with moving images. On the other hand, A-2D may be more adept with fast moving images. The best way to decide which decoding filter to use is to try out each one and compare their performances with the actual source.

Table 3.1 Available decoding filters and recommended usage Decoder Application A-3D Static images requiring optimum performances (adaptive) A-2D Fast moving images requiring optimum performances (adaptive) 3-D Static images (non-adaptive) 2D Fast moving images (non-adaptive) SPLT Lower quality source AUTO Bandsplit filter for unstable VCR signals

Adaptive luma comb decoding for stable VCR signals

N.B.: There is no filter selection available during SECAM operation. 3.7 Timing

When the ASD-231i is set to STUDIO source type and there is no reference signal installed, it operates in Frame Delay/Frame Buffer mode: the timing adjustment sets the processing delay between the input and output signals. Note that when operating in Frame Delay/Frame Buffer mode, the minimum vertical timing adjustment value is fixed by the number of processing steps selected (see table 3.2 for details) . However, when a reference signal is installed, the ASD-231i

14

is in Frame Synchronizer mode: the timing adjustment sets the processing delay between the reference and output signals.

3.7.1 Vertical Timing The vertical timing adjustment is made in increments of 1 video line up to 524 lines in NTSC and PAL-M and 624 lines in PAL, PAL-N, and SECAM. Follow these steps in order to adjust vertical timing: 1. Press SELECT to enter the menu. FRMT is displayed. 2. Press the DOWN(-) push-button until TIMG is displayed. 3. Press SELECT to enable the phase menu. VERT is displayed. 4. Press SELECT to enable the vertical timing menu. The current timing delay in video lines is

displayed. 5. Press UP(+) to increase the timing delay and press DOWN(-) to decrease the timing delay.

Press UP(+) and DOWN(-) simultaneously to set the timing to 0 lines. 6. Press SELECT to store the new vertical timing for the current format. VERT is displayed. 7. Press ESCAPE to return to TIMG. 8. To return to normal mode, press ESCAPE. Note: Vertical timing is not available when using SATELLITE or VCR source types and

when no reference signal is detected. When operating in Frame Buffer/Frame Delay mode (Studio source type w/o

reference signal), the minimum vertical timing adjustment value changes with the number of processing steps selected. Table 3.2 shows the minimum values for different processing selections:

Table 3.2 Minimum Vertical Timing Adjustment for Decoding Filter and TPAL selection (see section 3.14 for details on TPAL Selection)

Decoding Filter TPAL Minimum Vertical Timing Adjustment Value

A-3D / 3D OFF 1 A-2D / 2D OFF 2

SPLT OFF 2 AUTO (VCR) OFF 2

A-3D / 3D ON 2 A-2D / 2D ON 3

SPLT ON 3 AUTO (VCR) ON 3

3.7.2 Horizontal Timing The horizontal timing adjustment is made in increments of 1/2 pixels up to a range of one video line (63.5 us in NTSC and PAL-M and 64.0 us in PAL,PAL-N, and SECAM). Follow these steps in order to adjust horizontal timing: 1. Press SELECT to enter the menu. FRMT is displayed. 2. Press the DOWN(-) push-button until TIMG is displayed. 3. Press SELECT to enable the phase menu. VERT is displayed. 4. Press UP(+) or DOWN(-) to display HOR.

15

5. Press SELECT to enable the horizontal timing menu. The current timing delay in us is displayed.

6. Press UP(+) to increase the timing delay and press DOWN(-) to decrease the timing delay. Press UP(+) and DOWN(-) simultaneously to set the timing to 0 us.

7. Press SELECT to store the new horizontal timing for the current format. HOR is displayed. 8. Press ESCAPE to return to TIMG. 9. To return to normal mode, press ESCAPE. Note: Vertical timing is not available when using SATELLITE or VCR source types and

when no reference signal is detected. 3.8 Gain
