ITU H.264: The Advanced Video Coding Standard

The ITU-T has prepared a brochure giving an overview of ITU-T's H.264 advanced video coding standard. The increased compression efficiency of the new ITU-T H.264/MPEG-4 Advanced Video Coding (AVC) standard will lead to new application areas and business opportunities. Broadcasting over cable, satellite, cable modem, terrestrial, etc., will benefit from the new standard. It is now possible to transmit video signals at about 1 Mbit/s with TV (PAL) quality, which enables streaming over xDSL connections. Another interesting business area is TV transmission
over satellite. By choosing H.264, the number of programmes per satellite can be doubled in comparison to current systems using H.262 (MPEG-2). Also, in the field of mobile communication, H.264 will play an important role because the compression efficiency will be doubled in comparison to the coding schemes previously specified by Third-Generation Mobile (3GPP and 3GPP2) for streaming.

The new Recommendation is destined to influence further application areas including but not limited to the following:
* Interactive or serial storage multimedia (ISM or SSM) on optical and magnetic devices, DVD, etc.
* Real-time conversational services (RTC), such as videoconferencing and videophone, over ISDN, Ethernet, LAN, DSL, wireless and mobile networks, modems or mixtures of these.
* Video-on-demand or multimedia streaming services, such as remote video surveillance (RVS), over ISDN, cable modem, DSL, LAN, wireless networks, etc.
* Multimedia Messaging Services (MMS) over ISDN, DSL, Ethernet, LAN, wireless and mobile networks, etc.
* Multimedia services over packet networks (MSPN), such as multimedia mailing (MMM), etc.
