摘要
在简单介绍SIP(Session Initiation Protocol)协议的基础上,详细说明一个基于NGN网络的SIP协议的集中式视频会议系统的设计与实现。该系统由会议管理系统、会议控制系统和会议终端系统三部分组成。给出了基于SIP的视频会议系统的设计,各个子系统实现的关键技术,并讨论了系统有待解决的一些问题。
Based on the simple introduction of SIP protocol, the design and implantation of a centralised video conference system based on SIP protocol of NGN net has been expatiated. The system includes three components： conference control system, conference management system and terminal system. The design of the SIP based video conference system as well as the key techniques used to implement each sub-system are presented. Some issues needed to be further solved in the system are discussed as well.
