摘　　要：本文基于Directshow和Windows Socket技术,建立了一种流媒体视频混合及网络传输系统,实现了两路视频流媒体的混合,给出了混合视频流网络传输的解决方案。即在一台视频流媒体服务器、一台终端和一条低带宽线路的条件下同时传输两路/多路动态视频流,并且可以随时调整叠加视频的位置和Alpha值;具有客户端简单,节约带宽,传输效率高,传输信号准确清晰的优点。This paper based on the direct show and windows socket technology, to study and build up a streaming media video blend and a network transmission system. It successfully mix the two line of video streaming media , use one video streaming media server, one terminal, one low-bandwidth circuitry to transmit two line of dynamic video stream, it can adjust the position and the size of the folded video program at any time as well as the alpha value of the folded video. There is no need to increase the bandwidth, it has such strongpoint as simple client, high efficiency of transmission .
