| Abstract: | 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. |
