摘要
ＭＰＥＧ４标准面向众多而非特定的应用。它灵活、可扩展，满足未来音频视频应用的广泛需求，实现基于内容的交互性、可重用性和可伸缩性。本文介绍ＭＰＥＧ４系统框架、接收端模型、系统层模型、视频对象平面、基于模型编码和基于语义编码。
MPEG 4 addresses a wealth of applications instead of a specific one, providing flexibility and extensibility for the various requirements of upcoming audiovisual applications, realizing content based interactivity, reusability and scalability.The paper gives an introduction to MPEG 4 system framework, system receiver model(SRM),system hierarchy model,video object plane(VOP),model based coding and semantic based coding.
