| 摘 要： | 文章设计了一个用于视频流分发的应用层组播系统,系统由视频采集、视频编解码、组播传输和服务器4个模块构成。视频捕获采用Video for Windows(VFW)技术实现,编解码基于H.263标准。网络结构上提出使用混合P2P树形结构,降低了中心服务器的压力,服务器负责会议成员信息的管理,为组播树的建立与维护提供支持,组播传输使用基于度约束的构造算法,考虑了节点带宽和计算能力。该系统已投入运行,基本达到设计目标。

| Abstract: | This paper designs an application layer multicast system to be used in distributing video stream.It consists of four modules:video capture,video coding and decoding,multicast transmission and server.Video capture is realized through adopting Video for Windows(VFW) technology,and H.263 standard is used for coding and decoding.Hybrid P2P tree network architecture is used in network structure to reduce the pressure of the central server,and the server is responsible for the information management of the member... |
