| 摘 要： | 针对浏览器／服务器(Browser／Server)模式的各采集点监控图像的远程调看，该文提出基于B／S视频监控流媒体的发布系统，给出该系统的组织结构，叙述了采集、编码、流媒体、Web服务器以及远程终端等结构原理，进而描述了其发布过程和传输层次结构；同时针对广域网负载能力跳变和宽带视频的实时性需求之间的矛盾，提出了基于丢包率检测的带宽自适应码率传输模型和控制机理，并给出了技术实现的具体方法。

| Abstract: | To descry the long -range monitor video in manner of Browser/Server, this paper brings forward a stream-media promulgating system based on the B/S video surveillance, and presents the structure and rationale of its collecting, coding, stream-media promulgating, web server and terminal, then analyzes the promulgating process and transfers hierarchy, finally gives a bandwidth adaptive rate-control model and the realization scheme which is based on the detection of packet losing rate and used to resolve the conflict between the fluctuation of WAN load capability and the requirement of video real -time transmission. |

| Keywords: | video surveillance system network promulgating Browser/ Server bandwidth adaptive rate control |
