2nd The goal… ITU-T Recommendation H.264 or

ISO/IEC MPEG-4 part 10 Advanced Video Coding (AVC)

Goals for development: create a standard capable of providing good video quality at

substantially lower bit rates than previous standards

Intended for a wide variety of applications: low and high resolution video Broadcast DVD storage IP network ITU-T multimedia telephony systems

Security Systems

3rd: The directions… The standard includes several sets of capabilities, which are referred

to as profiles, targeting specific classes of applications.

Two are relevant to CCTV video encoding:

Baseline ProfilePrimarily for applications with limited computing resources, this profile is used widely in videoconferencing, mobile applications and CCTV video encoding.

Main ProfileOriginally intended as the mainstream consumer profile for broadcast and storage applications. Now implemented by Bosch for recording of CCTV Video.

H.264 profiles - Baseline Bare recommendation, does not support interlaced video (field

coding) This dictates that the maximum resolution is 2CIF

For those systems requiring medium resolution Bosch provides optimum investment protection, by supporting H.264 Baseline profile @ 25IPS on existing IP cameras and encoders with the release of firmware 4.0.

H.264 it’s a standard... right? YES… The decoding part is standard, although not all created

equal…. Profile building blocks can be picked at leisure Which can be some; Or many……

But all maybe called ‘H.264’

the following Network Layer Communications: Local and remote device discovery Device management Imaging/ media configuration Real time streaming of audio and video Event handling Video analytics PTZ (Pan, Tilt and Zoom) control security

Includes streaming set-up and control from JPEG, MPEG-4 & H.264 network video devices but does not cover compression standards.

FW 4.0 is ONVIF 1.0 readyDevice discovery, configuration and media service (MJPEG + H.264) are supported.

PTZ, event and imaging services are not supported yet. Fully compliant with the official ONVIF Test Tool 1.01.
