Research and Implementation of RTP/RTCP in Mobile Video Surveillance System

As people for the need on more security, traditional fixed video surveillance cannot satisfied with people’s varying requirements. This paper demonstrates the framework of a set of mobile video surveillance which support CDMA2000/TD-SCDMA/WCDMA network, RTP protocol is chosen as the transport protocol and H.264 is chosen as the video compression standard. Select RTCP protocol gather packet loss fraction parameter that controls the transmission rate of RTP traffic. We analyze RTP/RTCP protocol and media data transmission process in video surveillance system; discuss the current video transmission method in video surveillance system, the problem of packet loss while transporting video data, and extract packet process of RTP packet.
