基于Linux的视频监控系统中音视频的传输

Transporting Audio-Video Data in a Linux-Based Video-Monitoring System

讨论了视频监控系统音视频传输的关键技术:实时传输协议(实时传输控制协议、多播).对于多媒体实时传输中的丢包、带宽调整等问题,在分析其常见解决方案的基础上,提出了新的解决方法:采用简单的FEC纠错和重发相结合的方法解决丢包问题;采用多数表决法进行带宽调整.

Network videomonitoring system has great prosperity. Transporting audiovideo data in videomonitoring system is a key issue. This paper discusses some keytechnologies of transporting audiovideo data in videomonitoring system, such as RTP?RTCP and multicast. The paper also gives methods to solve some problems in realtime transportation of the multimedia such as packet loss?bandwidth control. It is shown that Combine FEC and retransmission can reduce packet loss and use majoritydecision method to control bandwidth.
