摘　　要：针对视频点播系统中存在的高带宽、高存储、低并发性等问题,提出了一种基于流媒体的小型分布式的视频点播系统,通过把视频进行分段并动态分布到不同的服务器实现了分布式存储.通过文件共享机制并在数据库中纪录和维护视频信息实现对不同视频服务器上视频资料的统一管理.仿真测试结果表明,该方案能大大提高视频点播系统的并发访问量,并可动态添加视频服务器以满足日益增长的视频点播需求.To the problems of high bandwith,high storage and low concurrency,a technology of simply distributed VOD system which is based on stream media was proposed.By the means of dividing video into several sections and deploying them to different video servers,solved the issue of distributed storage.By the means of file sharing and recording the video information to database,solved the issue of unified management for video information..Experiments show that the solution can service more clients,and can add additional video servers to meet the increasing demands.
