摘要
视频会议作为多媒体应用的重要组成部分,为两地用户创造了直接、完整的沟通途径,在社会信息沟通中起到了重要作用。目前,中国已发展了多种不同的视频会议系统,其主要有2类视频会议系统协议,一类是H.323协议,另一类则是基于会话初始协议(Session Initialization Protocol,SIP)的协议。因为H.323视频会议系统的复杂度和灵活性,其正逐步被更简单灵活的SIP视频会议系统所替代。随着下一代互联网信息技术的蓬勃发展,SIP协议也开始成为在高度融合的互联网环境下,实现现代视频会议系统的最终解决方案。
Video conference,as an important part of multimedia application,has created a direct and complete communication channel for users in two places,which has had a significant impact on social information communication.Video conferencing systems have continued to evolve in recent decades.At present,China has developed a variety of different video conference systems.There are mainly two kinds of video conferencing systems,one is H.323 protocol,the other is based on Session Initialization Protocol(SIP)protocol.Due to its complexity and flexibility,H.323 video conferencing systems are gradually being replaced by simpler and more flexible SIP video conferencing systems.With the vigorous development of the next generation of Internet information technology,SIP protocol has become the ultimate solution to realize modern video conferencing system in the highly converged Internet environment.
