【摘要】 Internet服务质量 (QoS)的时空波动性给设计和实现Internet实时视频流系统提出了巨大的挑战。以终端系统为研究对象 ,给出了端到端的Internet视频流系统结构 ,建立了基于Gilbert模型的信道包丢失率计算方法 ,提出了位率自适应视频流协议SAVSP。实验结果表明 ,所提出的视频流系统结构合理 ,SAVSP协议性能优于目前主流的AIMD协议。更多还原

【Abstract】 The fluctuant QoS(Quality of Service)of Internet presents great challenges to design and implement the Internet real-time video streaming system.Based on the end-system,the authors propose an end-to-end Internet video streaming architecture and a rate adaptive video sureaming protocol(SAVSP),and a packet loss rate algorithm based on Gilbert Model is also put forward in this paper.Experiments show that the video streaming architecture is practical,and the SAVSP protocol outperforms the prevalent AIMD protocol.更多还原
