H.263的发展及应用

摘要

H.263是一种面向低比特率视频通信应用的视频压缩标准，它具有较高压缩比、较强鲁棒性，尤其适用于PSTN及无线/Internet网络环境下的视频传输。介绍了H.263的基本框架和关键技术、所包含的各种高级模式，并结合典型应用场合，对纷繁的高级模式做了归类。%H.263 is a video coding standard at low bit rate,which can compress the video efficiently and support robust transmission over PSTN and Wireless/Internet network.The baseline encoder framework,key technologies and optional modes in H.263 are introduced. Finally,the numerous and complicated optional modes are classified according to typical applications.
