SIP和RTSP协议转换模块的设计与实现

随着流媒体技术与IP通信技术的快速发展,SIP协议与RTSP协议的互联互通问题日益凸显.论文从信令对应、地址映射、交互流程设计等几个方面对SIP与RTSP协议互通进行了论述,并在RTSP代理服务器的基础上,设计并完成了SIP与RTSP协议转换模块,实现了SIP信令与RTSP信令的转换功能.最后,论文以SIP Client 访问RTSP摄像头获取实时画面为例,验证了该方法的可行性与正确性,为基于SIP的多媒体调度系统与RTSP设备的集成问题提供了较好的解决方案.

Design and Implementation of the SIP and RTSP Protocol Conversion Module

As the rapid development of streaming media technology and IP communication technology, the SIP protocol and RTSP protocol interoperability issue becomes increasingly prominent. This paper discusses the protocol communication problem between SIP and RTSP protocol from the aspects of protocol method corresponding, address mapping, interactive process design and so on. And based on the RTSP proxy server, the SIP and RTSP protocol conversion module is designed and implemented, realized the protocol method conversion between SIP and RTSP. Finally, the paper verifies the feasibility and validity of the method by taking SIP Client access RTSP camera to obtain real-time image as an example, which provides a good solution for the integration between the multimedia scheduling system based on SIP protocol and RTSP devices.
