【摘要】 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 Protocol)、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。更多还原

【Abstract】 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 communication 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.更多还原
