Design Of Video Monitoring System Based On The Embedded

Video monitoring technology is developing quickly, the market demand is growing fast. The development of embedded wireless video monitoring adapted to the requirements that monitoring system has small volume, low power consumption, also can be esay to arrange and be monitored removable. It has wide application prospect.Through the study of embedded technology and several other popular electronic technology, i.e., the multimedia technology, communication technology, etc., this paper proposes a scheme based on embedded wireless video monitoring system, through the hardware such as ARM development board, USB peripherals, infinite routing,etc,to achieve video surveillance under the embedded Linux operating system. Paper first explains the application of embedded video monitoring system in the market demand, feasibility, presents the overall scheme of the system, respectively from two aspects of hardware and software design, among them, the system has the function of the specific implementation depends on software together. Then set up cross development environment, under the environment of the Bootloader, kernel and root file system and service development and transplantation. Secondly introduced to realize video collection function, based on the V4L video must carry on the compression to transmit the data collected, it detailed introduces the h.264video compression coding standard, aimed at the key module of the algorithm has been optimized, using optimization algorithm, compared with the old algorithm, the complexity is reduced greatly, improve the efficiency, save the process. Finally introduced the video data transmission process of the relevant agreements, including: real-time transmission protocol RTP, and real-time transport control protocol RTCP, set up a local area network (LAN) based on the wireless router, within the LAN of computer video information, the receiving end are acceptable to monitoring purposes.
