基于STB和SIP视频通信软件设计及测试

Design and Test of video communication software based on STB and SIP

本文中的视频呼叫控制协议选用SIP协议,通信数据的传输承载于NGB网络。设计了总体软件流程,包括STB与SIP终端之间的通信流程,视频播放浏览器模块与视频通信模块之间的接口函数。最后搭建模拟测试平台,对所构成的视频通信模块进行了测试;同时利用Wireshark1.6.1抓包软件,抓取SIP协议数据包,验证了SIP协议能够正常工作,可应用于简易的视频通信。

This paper video call control protocol SIP protocol,data transmission and communication capacity in NGB network.The design of the overall software process,including the communication process between STB and SIP terminal,video playback interface function between the browser module and video communication module.Finally the simulation test platform,the video communication modules are tested ;at the same time using Wireshark1.6.1 packet capture software,grab SIP protocol data packets,to verify the SIP protocol can work normally,can be used in video communication simple.
