| Abstract(in English) | The proxy mechanism widely used in WWW systems offers low-delay and scalable delivery of data by means of a "proxy server". By applying proxy mechanism to video streaming systems, high-quality and low-delay video destribution can be accomplished without imposing extra load on the system. In addition, the quality of cached video data can be adapted appropriately in the proxy when clients are heterogeneous, in terms of the available bandwidth, end-system performance, and user preferences on the perceived video quality. In this paper, we propose, design, implement, and avaluate a proxy caching system for MPEG-4 video streaming services. Through evaluations conducted from several performance aspects, we proved that our proxy caching system can provide users with a continuous and high-quality video streaming service in a heterogeneous environment. |
