为了应付流媒体系统应用网络带宽不足问题，设计了基于多码率文件传输技术和可变编解码参数Filters播放链路动态重连机制的自适应流媒体传输系统。该系统在网络带宽发生波动的条件下，能够自适应地选择与可用带宽相匹配码率的视频数据进行动态传输，进而减少视频数据缓冲等待次数和等待时间，有效提高网络带宽利用率和媒体内容服务质量，同时采用“最短”的链路进行媒体内容的动态重连，避免Filters动态重连中出现“卡塞感”，有效提高流媒体系统的服务质量。

In order to improve the insufficiency of network bandwidth applied to streaming media system,a new adaptive streaming media transmission system was design based on multi-rate file transmission technology and Filters play link dynamic reconnection mechanism with variable codec parameters. This system can adaptively select the video data which can match code frequency with the available bandwidth,reduce the video data buffering waiting count and time,effectively improve the network bandwidth utilization and the service quality of media content. The "minimum”dynamic link length is adopted to make dynamic reconnection with media content to avoid the "pause flu" in Filters dynamic reconnection,and effectively improve the service quality of streaming media system.
