Applications And Improved Processing Of MPEG-4 Video Compression Algorithms In Monitoring And Control System

With economic development and urban construction accelerated Safe city into the trend of social development, most of the existing security system as the main of urban construction, Currently the city's video surveillance security mainly through optical fiber mode with various control points of the video signal sent to the monitoring center, the person monitor the different control points by the Artificial selection, the advantages of such a monitoring mode as follows:According to the needs of staff can monitor, direct control of some particular place, particular people with high intelligence, and the suspect can not be detected in the case of monitoring. But its shortcomings are clear, and monitoring centers to simultaneously monitor the target is very limited, if these surveillance video to effectively manage them and reduce the burden of monitoring staff, on a timely alarm of some sensitive sites would effectively improve the city's performance and efficiency monitoring system.。The subject is based on knowledge of intelligent control technology and research theory, adopt the new ideas and methods of control.The system aim at activities for large numbers of public places,as a complex and characteristics of population mobility greatly.The teachnology of CPLD will be integrated into the signal processor of DSP, implementation of the four video hardware access and processing, Meanwhile, the system uses intelligent video processing technology, and also identify separately the person or the entities and the behavior of entities these appear in public places effect,.Solving the traditional public places in the monitoring system can only be related to surface, but can not track the point of issue.In addition, the system through the embedded operating system and implementation of compression technology of MPEG-4 about video, increased data storage capacity on your hard disk greatly, and achieve real-time remote monitoring and data transmission.The main subject is optimize the compression system in the smart control system and proposed an adaptive compression strategy, improve the compression efficiency further, not only guarantee the video quality but also save hard disk space, Experiments show that the technique has a good novel.If the transformation can be carried out, it Will have a very broad market.
