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:
MPEG - 4 provides the standardized technological elements enabling the integration of the production, distribution and content access paradigms of the three fields.
The MPEG - 4 standard provides a set of technologies to satisfy the needs of authors, service providers and end users alike.
For all parties involved, MPEG seeks to avoid a multitude of proprietary, non - interworking formats and players.
MPEG - 4 achieves these goals by providing standardized ways to:
Composition and manipulation of MPEG - 4 videos (VOP = Video Object Plane)
The hierarchical structure of JPEG - 4 visual bitstreams is very different from that of MPEG - 1 and 2 in that it is very much video - object - oriented. In general, each Video - object Sequence (VS) will have one or more Video Objects (VOs), each VO will have one or more Video Object Layers (VOLs), and so on. Syntactically, all five levels have a unique start code in the bitstream, to enable random access.
Comparison of interactivities in MPEG standards: (a) reference models in MPEG - 1 and 2 (interaction in dashed lines supported only by MPEG - 2); (b) MPEG - 4 reference mddel

nonscalable coding. As a special case, MPEG - 4 also supports a special type of VOL with a shorter header. This provides bitstream compatibility with the baseline H.263.
