摘要
在网络监控系统中,实时流媒体传输已经广泛使用,其中音视频同步是一个关键的问题。由于在数据传输中使用RTP协议,如果能有效使用RTP包中的时间信息,音视频同步问题将会大大简化。根据做网络监控系统软件的经验,充分利用RTP协议中的时间戳,提出参考时间,缓存设计及音视频同步算法,并进行编程。
Real- time streaming media transmission is used widely in the network monitoring system, and audio -video synchronization is a key issue. Since the use of RTP protocol in data transmission, the synchronization requirements can be simplified greatly if the time information in RTP data packets is used effectively. Based on the experience in programming the network monitoring system, the timestamp in the RTP protocol is made full use, how to set reference time and the timestamp and how to program the audio -video synchronization are expressed.
