从流媒体协议入手，描述会话发起协议SIP（Session Initiation Protocol）、实时传输协议RTP（Real-time Transport Pro-tocol）、实时传输控制协议RTCP（RTP Control Protocol）和实时流传输协议RTSP（Real-Time Streaming Protocol）的原理以及它们在IP单播或多播网络上的通信过程。在此基础上，进一步分析RTP/RTCP和RTSP协议的关系，并对基于RTP/RTCP和RTSP协议的流媒体服务器进行设计。流媒体服务器是视频监控系统的核心部分，采用C/S结构，服务器和客户端之间的多媒体数据之间的传递都在这一部分完成。在基于RTP/RTCP和RTSP协议的流媒体服务器的基础上，使用SIP协议让用户和服务器建立会话连接，并在流媒体服务器上进行多媒体数据的传递，从而设计出基于SIP、RTP/RTCP和RTSP协议的视频监控系统。

This paper analyzes the streaming media protocols , describes the principle of SIP ( Session Initiation Protocol ) , RTP (Real-time Transport Protocol), RTCP(RTP Control Protocol) and RTSP(Real-Time Streaming Protocol) as well as their com-munication course on network.Furthermore, this paper also analyzes the relationship between RTP /RTCP and RTSP, and designs the streaming media server based on RTP/RTCP and RTSP.The streaming media server is the most important part of this video surveillance system which uses the C/S structure and provides the service of the multimedia data transmission .At last, this paper analyses the design of video surveillance system based on SIP , RTP/RTCP, and RTSP.
