Research And Realization Of Video Surveillance And Play Based On ARM9Hardware Platform

In recent years，the video surveillance system has gotten a rapid development, which canbe used in more and more fields. At the same time, with the development of network anddigital technology, the video surveillance system is being replaced from analog to digital. Sonot only the quality of the video and the stability of system have been improved，but also dosethe digital system have a great anti-interference capacity which can be easily stored andtransmitted.In this paper, a design of embedded network video surveillance system is proposed bycombining embedded, video and network technologies together. The system based on IPnetwork, can realize the remote video surveillance, which abtains capturing the video bycamera, compressing by the video compress module, then transmitting to web server throughthe data bus. Thus the users in client can view the video from web server by using browser orrelevant tool. So, this system makes that it can be monitored everywhere without thelimitation of distance.This paper is about a system of video surveillance and playing, which uses32-bitsARM9MPU S3C2410X as the core and chooses the advanced Linux2.6as the kernel. In thisthesis, both the hardware part and the design part of each functional model are introduceddetailedly, which includes the video capturing module， video compressing module,transmission module, the establishment of Web Server, Mplayer transplanting, the design ofthe interface by Qt/Embedded, and so on.
