Summary

The Moving Picture Experts Group (MPEG) is a working group of the ISO/IEC international standards community charged with the development of international standards for compression, decompression, processing, and coded representation of moving pictures (video), audio, and the combination of both audio and video. To date, MPEG has produced three international standards: MPEG-1 (ISO/IEC 11172), MPEG-2 (ISO/IEC 13818), and MPEG-4 (ISO/IEC 14496). The fourth MPEG project, MPEG-7, is expected to be standardized as ISO/IEC 15938 in September 2001.

Whereas the MPEG-1 and MPEG-2 standards are designed for fixed media and high-bandwidth applications (such as CD-ROM, DVD, and digital television), MPEG-4 is a toolkit of technologies created specifically to enable multimedia over slow and variable-bitrate networks (such as wireless communications devices and the Internet). MPEG-4 version 1 was standardized by ISO/IEC in October 1998, while version 2 received international standardization in December 1999.
