| As embedded technology is becoming an important branch of computer technology, thecombination of video coding and embedded technology become the drive force of a videosurveillance system. Due to the limitation of embedded processor performance and the highdemands of monitoring system, video coding becomes an effective way to improve theutilization of network bandwidth. Efficient encoding and decoding of the H.264standard with anexcellent network adaptability become a good choice.A scheme of video web surveillance system based on B/S mode is presented. The keytechnology of video capturing, video codec and web server is implemented. In order to meetneeds and goals of web video monitoring system, the S3C6410ARM11chip and embeddedoperating system Linux as software platform are proposed. The surveillance system based onBrowser/Server mode is presented to fulfill the system flexibility and real-time processing.According functional division, the system software environment is built. The driver of cameradevice base on v4l2are particularly researched and realized. The use of an internal encodingmulti format codec model and the real-time streaming transport protocol RTP is accomplished.The system is tested and analyzed in the end. |
