可视电话、远程医疗与教育等业务的核心技术是数字终端的音视频实时通讯.通过分析视频通讯的硬件网络摄像机、机顶盒等硬件平台和RTSP协议流式传输的网络摄像机模块,提出自适应RTSP流式直播模式的机顶盒客户端方法,实现了数字终端视频流式实时传输与机顶盒视频通讯.本方法既可同时支持标准RTSP协议和微软的RTSP协议,又可实现视频通讯系统与PC进行互联互通,解决了数字终端与PC之间可视通讯问题,在面向3C融合互联互通的应用方面具有广泛的前景.
Video real-time communication of digital terminal is the core technology for video telephone,telemedicine and tele-education.By discussing the video communication hardware platform of both IP crammer and STB and software of IP crammer based on RTSP protocol on server client,an adaptor stream transmission method for client is proposed.The real-time video communication between digital device and IP is achieved.Not only does it support both standard RTSP protocol and Microsoft RTSP protocol in same time,but also solves the communication problems between video devices and PC.It will be widely used in oriented 3C interactive applications.
