摘　　要：为满足网络用户对流媒体的需求,提出一种新型网络流媒体系统架构,并给出实现方法.该系统基于RTSP等流媒体协议,采用组播等通信方式实现多用户电视转播.系统通过构建媒体对象模型,实现对多种文件类型并存情况的处理.实验结果表明采用RTSP质量控制节约网络资源和服务器资源,能保证播放画面的细腻、流畅,质量较好.Aiming at the fast development of networks, a novel streaming-media IPTV system is presented and its implementation is put forward. The system is based on RTSP. Multi-cast was selected as the communication model of the system. The system utilized the RTSP feedback mechanism to ensure qos and employed multi-cast to rebroadcast programs to clients. The applications show the system has good performance in IPTVs.
