The Research And Implementation Of Vehicles Surveillance System On Wlan

With the development of the internet, network transmission bandwidth is getting higher and higher, evolution of audio and video compression coding technology, image transmission to remote surveillance is gradually applied. Embedded network video surveillance system is an embedded technology, video compression technology and network transmission control technology as the core of the new video surveillance system. The thesis includes the following five parts:First: Analysis of WINCE embedded operating system, JPEG image compression, WLAN wireless local area network.Second: Depth analysis of the RTP/RTCP features, working principle and analysis of the structure of RTP/RTCP.Third: Given a video transmission and packet loss rate control strategy, to improve the video transmission and better display, especially in the bad network environment.Fourth: Design and implementation of video surveillance systems, completed camera control, video transmission display functions.Last: Given the system performance test. Including the effect of customized embedded operating system, video image transmission performance parameters,and the system deficiencies, areas for improvement.
