Effective video-on-demand transmission scheme under RCBR network

This paper presents an effective VOD transmission scheme under RCBR network that is suitable for the statistically non-stationary video traffic since it supports the bandwidth renegotiation during data transmission. The proposed system includes two parts: the VOD server architecture and traffic smoothing/admission control algorithms. The proposed VOD server system consists of video DB and metadata DB that includes compression history information including the quantization parameters versus output rate profile, encoded frame positions and encoding types, etc. And, the proposed traffic smoothing and admission control algorithms are performed based on the aforementioned metadata and control the traffic properties of the selected VOD through the communication between them to be accommodated under the current network situations. And, the experimental results are provided to demonstrate the efficiency of the proposed system.
