Multimedia technology and networks protocol are the basic technology of the video surveillance system. A network
remote video surveillance system based on MPEG-4 video coding standards is designed and implemented in this paper.
The advantages of the MPEG-4 are analyzed in detail in the surveillance field, and then the real-time protocol and
real-time control protocol (RTP/RTCP) are chosen as the networks transmission protocol. The whole system includes
video coding control module, playing back module, network transmission module and network receiver module The
scheme of management, control and storage about video data are discussed. The DirectShow technology is used to
playback video data. The transmission scheme of digital video processing in networks, RTP packaging of MPEG-4 video
stream is discussed. The receiver scheme of video date and mechanism of buffer are discussed. The most of the functions
are archived by software, except that the video coding control module is achieved by hardware. The experiment results
show that it provides good video quality and has the real-time performance. This system can be applied into wide fields.
