Research And Design On Real-time And Dynamic Network Video Multiuser Controlling System Model

With the development of the technology of NGN(Next Generation Network), Web Service, intelligent network Camera, the technology of support for network, multimedia and heterogeneous system has been more and more practicable. So many businesses, such as voice, video, dates, and so on, can be integrated with a synthesized, full-opened network platform. The system of real-time and dynamic network video, which integrates communication technology, intelligent control technology, will be used widely in all field of computer application, such as safety precautions, long-range surveillance and control, teleclass, sickroom electronic surveillance, community service, and so on.The paper, based on the thesis of internet and network video, designs a scheme for multi-users access real-time and dynamic video system, and puts forward a blue-print for it. The paper applies OOSE, UML technology to design and implementation of the system. It discusses how to use the formal mathematic specifications to design key-block of system. It researches on implementation of system combined with data encapsulation, abstract data type, information hiding. In implementation of the core algorithm organization, the paper applies the thesis of queue in operational research to solve the competition of hardware when multi-users access. Also, after analyzing the performance of system, the paper puts forward a strategy for the optimization of system. Besides, one novel efficient face detection and tracking algorithm are presented, which adapts for the most typical personal secret controlling.
