摘　　要：针对目前网络计算机等网络终端设备在处理流媒体信息时没有专门的播放软件,且缓冲区长度设置不合理和占用网络带宽较大的问题,描述了一个以网络计算机为基础平台的流媒体播放器技术实现方法;利用RTSP协议,实现了对网络流媒体文件播放的实时控制功能。实践证明该播放器不但能良好地播放网络中的各种流媒体文件,而且占用较小的网络带宽,在设备资源的占用率与流媒体播放效果之间做出了良好的平衡,在一定程度上提高了资源受限的网络终端设备对大容量流媒体资源的处理效果。Aiming at the current network computer terminal device information in dealing with streaming media player without special software, and the length of the buffer zone set up unreasonable and occupied by the larger issue of network bandwidth, describes streaming media player technology method that based on network computer;Use RTSP protocol to achieve the streaming media files on the network playing real - time control functions. Practice has proved that the player will not only play well in a variety of network streaming media files,but also occupy less network bandwidth, so it made a good balance between equipment resources in the occupancy rate and the effects of playing streaming media files,also improved the effect between resource- constrained network computer and high- capacity streaming media resources.
