Abstract

In streaming media system, Static Streaming Scheme, like FB and GEBB, can reduce the usage of network bandwidth by using sharable multicast channel to deliver streaming, when most users access the same popular video. But Static Streaming Scheme has some problems: service delay, difficult to support interactive VCR and so on. To solve these problems, this paper proposes a new scheme HPHS and make some discussions to support interactive VCR. It merges the outstanding thoughts of HPSCT (revised from GEBB) and Patching scheme. The scheme aims at delivering popular video, allocates the number of channels adaptively according to request rate to minimize the network bandwidth consumption and satisfy the real-time playback requirement. Simulation results show that the scheme HPHS is high performance to decrease the usage of server bandwidth in Streaming media system.
