MPEG-4
MPEG-4 is an ISO/IEC standard developed by MPEG (Moving Picture Experts Group), the committee that also developed the Emmy Award winning standards known as MPEG-1 and MPEG-2. These standards made interactive video on CD-ROM, DVD and Digital Television possible. MPEG-4 is the result of another international effort involving hundreds of researchers and engineers from all over the world. MPEG-4, with formal as its ISO/IEC designation 'ISO/IEC 14496', was finalized in October 1998 and became an International Standard in the first months of 1999. The fully backward compatible extensions under the title of MPEG-4 Version 2 were frozen at the end of 1999, to acquire the formal International Standard Status early in 2000. Several extensions were added since and work on some specific work-items work is still in progress. MPEG-4 builds on the proven success of three fields:
Digital television;
Interactive graphics applications (synthetic content);
Interactive multimedia (World Wide Web, distribution of and access to content)
MPEG-4 provides the standardized technological elements enabling the integration of the production, distribution and content access paradigms of the three fields, it designed specially for low-bandwidth (less than 1.5MBit/sec bit rate) video/audio encoding purposes.
