基于Web的带宽自适应组件化多媒体监控系统

当前的分布式多媒体监控系统存在通用性、易用性和扩展性不足等缺点,且不能自适应多种网络状况.为解决其通用性、易用性问题,参考流媒体系统结构,给出了基于Browser/Server模式的监控系统结构.为增强其可扩展性,在DirectShow技术基础上,设计了基于COM的监控系统软件结构.采用带宽自适应的策略和方法,实现了系统对多种网络状况的动态自适应. 

Web and component based bandwidth adaptive multimedia surveillance system

The useability and expandability are insufficient in digital multimedia surveillance systems. Most of them cannot be adapted to the fluctuation of available network bandwidth. To enhance the useability, the new surveillance structure was presented, which based on browser/server model and media streaming system structure. To improve the expandability, the new surveillance software architecture was designed, which based on DirectShow architecture and component object model and combined unicast with multicast. To be adapted to the available network bandwidth dynamically, the adaptive control strategy and method was introduced, and the closed loop feedback transmission system was accomplished.
