中文摘要：

通过对H．264／SVC和互联网P2P技术的研究，提出了复杂网络环境下的H．264／SVC视频流分发策略，设计了基于H．264／SVC视频流的P2P内容分发系统。该系统结合了H．264／SVC码流可伸缩和P2P易扩展的优点，实现了复杂网络环境下自适应视频码流传输，解决了异构终端间视频资源共享问题。

英文摘要：

In this paper, the strategies of H.264/SVC video stream distribution in complex network environment is proposed by studying the H.264/SVC and Internet P2P technology, then we design our P2P content distribution system implementation, based on H.264/SVC video stream. Our implementation takes the advantages of the scalability of H.264/SVC stream and the expansibility of P2P technology, enables rapid and reliable adaptive transmission of video streams and achieves the resource sharing among heteroge- neous terminals.
