A Transmission Scheme for Streaming Variable Bit Rate Video over Internet

In this paper, we consider transmission of variable bit rate (VBR) stored video for distributed streaming service. In streaming service over Internet, video server usually employs network congestion control protocol in order to adapt the dynamic change of network traffic. This protocol often results in the discontiguity of playback at client’s side. We propose a novel transmission scheme to overcome this problem. Under the proposed scheme, video server prepares basic transmission schedule of video by off-line processing of VBR video. Using this information, server can control the amount of data transmitted, which enables client to avoid the discontinuity in playback, even if the allocation of network bandwidth changes during service.
