Chapter 16. MPEG-4 OVERVIEW > MPEG-4: Coding of Audiovisual Objects

MPEG-4: Coding of Audiovisual Objects

MPEG-4, the third MPEG project, started in July 1993. The first version became an international standard in March 1999 (ISO/IEC 14496), while the second version was scheduled for standardization in December 1999.

The MPEG-4 standard addresses the coded representation of both natural and synthetic (i.e., computer-generated) audio and visual objects. MPEG-4 was developed to provide the necessary facilities for specifying how such objects can be composed together in a terminal to form complete scenes, how a user can interact with the content, as well as how the streams should be multiplexed for transmission or storage. The MPEG-4 term terminal is used in a generic sense and includes computer programs hosted on general-purpose computers.
