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
. These standards made interactive video on CD-ROM
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, whose formal ISO/IEC designation is 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 2000. Some work, on extensions in specific domains, 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.
More information about MPEG-4 can be found at MPEG’s home page: www.cselt.it/mpeg . This web page contains links to a wealth of information about MPEG, including much about MPEG-4, many publicly available documents, several lists of ‘Frequently Asked Questions’ and links to other MPEG-4 web pages.
The standard can be bought from ISO, send mail to email@example.com. Notably, the complete software for MPEG-4 version 1 can be bought on a CD ROM, for 56 Swiss Francs (approximately 40 US Dollars). This software is free of copyright
restrictions when used for implementing MPEG-4 compliant technology. (This does not mean that the software is fee of patents)

While MPEG is not my employer I do work for the same company as MPEGs founder and president Leonardo Chiarligione
who is the head of the multimedia division of Telecom Italia Lab
where I used to work.
