Abstract(in English) The proxy technique is originally developed for WWW system, but it is expected to be useful to improve the performance and quality of video streaming service. Furthermore, if each proxy is capable of adapting incoming or cached video data to user's demand, user's QoS requirements on video streams can be fully satisfied. For these purposes, proxies communicate with each other, retrieve a missing video block from an appropriate server by taking into account transfer delay and offerable quality, and adjust quality of the block to the client request. We show that our proposed mechanisms are effective in avoiding freezes during video playback and providing clients with high-quality and low-delay video streaming services.
