Design And Implementation Of Real-time Transmission Subsystem For Network Video Surveillance System

With digital technology, multimedia communications and IP broadband network technology and the continuing development of the field of information has been made revolutionary progress. Network video surveillance system was in the sudden emergence of this trend, and become hot spots of study, has broad prospects and the application of a high research value.Traditional analog video surveillance system is divided into control systems and two digital monitoring system, including digital monitoring system although some combination of the Internet and multimedia features, but in the functional and performance are not satisfactory. With computer technology, communications technology, microelectronic technology, the advances in network technology, real-time video compression and transmission possible. Network Video Monitoring System in the traditional system on the basis of the network combined with the latest technology, the video surveillance system from ordinary Security monitoring platform into a set of multimedia services, business processes, security protection, long-distance exchange for an integrated application platform.With Microsoft. Net Web services framework for the introduction of a new software development model - SmartClient model came into being, it combines the C / S and B / S the merits, all powerful features , flexibility, as well as C / S mode user experience with B / S model and the simplicity of the deployment of integration. At the same time, based on object code, the core content of the standard is based on the variability of the MPEG-4 compression standard, has now become the most important and most influential multimedia data compression coding one of the international standards.Based on SmartClient mode, and MPEG-4 compression standard. Net platform developed network of real-time video surveillance system transmission subsystem. The system software architecture, software modules, database, security aspects of the design, and to provide a strong FrameWork2.0 a series of components to achieve its. The system passed the test results showed that the function of the system, performance, operational efficiency, etc. reached a considerable level.
