Efficient Transmission Technique of VBR-MPEG Video for Interactive Video Service

In general, it is difficult to transmit a VBR video like MPEG efficiently since MPEG fames are construct with various size. To solve this problem, some bandwidth smoothing techniques are proposed which is based on the prefetching video data into the client buffer with low bandwidth allocation. However these techniques do not provide efficient bandwidth smoothing technology and transmission technique for interactive video services like VCR-like functionality. In this paper, we propose and evaluated a new bandwidth allocation mechanism for interactive video services which has VBR traffic characteristics such a MPEG. This technique provides VCR-like functionality which is not supported on previous techniques and also maximizes the bandwidth utilization when interactive video services are provided. Through our experimental, we prove that the proposed technique dramatically decreases a traffic and guarantee the continuous playback simulaneously.
