Research And Realization Of Video Monitoring System Based On Embedded UClinux

The video monitor system is an important part of security defense system, which is widely used in a lot of occasion, for its intuition and convenience. Recently, Video monitor system has been well developed along with a very fast speed development of the technology of computer, network and image processing, from traditional analog technology for modern digital technology. Embedded digital Video monitor system is the fastest development part of the domain of digital security defense system.Based on the analyses of the current situation of video supervise and characteristic,this paper bring forword a solution which is made up of embedded WEB server and vidicon and we can visit and control the system with Web. We use SAA7111A and IME6400 to process analog video into digital MPEG-4 video, and then send the encoded signals to embedded WEB server, so the server can send them to users on internet. We use S3C44B0X, which is ARM7 series microprocessor produced by Samsung co.,Ltd, and embedded OS uClinux to construct our video server. We also use the latest Linux kernel Linux-2.6 to update uClinux. The system only need one IP address, and users can see the images by their browser, authorized users also can operate and configure the system.Experiment is tested in school local netwok. The result indicates: users can broadcast clear and smooth picture at the same time, without obvious shaking and delay when they ask for WEB server;It can work well without delay when web server is controlled remotly.
