H.264
H.264/AVC/MPEG-4 Part 10 (Advanced Video Coding) is a standard for video
compression. The final drafting work on the first version of the standard was
completed in May 2003. H.264/AVC is the latest block-oriented
motion-compensation-based codec standard developed by the ITU-T Video Coding
Experts Group (VCEG) together with the ISO/IEC Moving Picture Experts Group
(MPEG), and it was the product of a partnership effort known as the Joint Video
Team (JVT). The ITU-T H.264 standard and the ISO/IEC MPEG-4 AVC standard
(formally, ISO/IEC 14496-10 - MPEG-4 Part 10, Advanced Video Coding) are
jointly maintained so that they have identical technical content. H.264 is used in such
applications as Blu-ray Disc, videos from YouTube and the iTunes Store, DVB
broadcast, direct-broadcast satellite television service, cable television services, and
real-time videoconferencing.
