摘要
为了提高视频监控系统的安全性和可靠性,通过分析现阶段的实时视频传输协议,提出了一种流媒体服务器与终端播放器间心跳机制的实现方法。该方法在实时流协议(RTSP)连接建立过程的基础上做了修改,保持原有的硬件部分不变,重构实时传输协议(RTP)数据包头部字段,增加含有终端信息的字段。结果表明,普通的实现RTSP的终端不能正确访问流媒体服务器,增加了流媒体服务器与终端间通讯的安全性和可靠性,提高了视频监控系统的整体性能。
In order to enhance the security and reliability of video monitoring system, an implementation method of heartbeat mechanism between streaming media server and terminal player is presented based on the analysis of existing real-time video transport protocols in this paper. The proposed method revised the connection establishment process of real-time streaming protocol （RTSP）, while kept the original hardware unchanged to rebuild the packet head field of real-time transport protocol （RTP） and add the terminal information field. Results show that the terminal with the original RTSP cannot access streaming media server. The method not only enhances the security and reliability of the communication between streaming media server and terminal, but improves the general performance of video monitoring system.
