摘要

流媒体点播技术定位于提供实时的文件点播服务，而WMV则是一种IPTV常用的文件格式。为了解决Linux或类Unix环境下对WMV文件格式的支持，设计了一个具有完全自主知识产权的支持WMV格式的Linux环境下的流媒体点播系统。该流媒体服务器采用创新的主从式架构设计，并设计了RTSP连接队列调度等算法，用来完善服务器的功能和提高服务器的性能。

Abstract

Video streaming applications provide on-demand video file playback services through the computer network. WMV is a common file format in IPTV applications. In order to support WMV formaton Linux orUnix-like platforms novel master-slave mode architecture is proposed in this paper. Based on this architecture

we designed and implement a WMV video streaming system on Linux platforms. Inside the server

we embedded several novel algorithms such as the RTSP query schedule algorithm to improve the performance. The whole system is successfully deployed in the Shanghai’s Archive Library.
