Distributed source coding techniques for interactive multiview video streaming

We investigate coding tools for interactive multiview streaming (IMVS), where clients interactively request desired views for suc-cessive video frames, and in response the server sends the appropri-ate pre-compressed video data to the clients. Solution based on using only I-frames to support view switching would incur high transmis-sion cost, while for that based on using only P-frames to encode every possible traversal, although it can minimize transmission cost, prohibitive server’s storage may be required. Therefore, efficient solutions for IMVS need to consider the trade-off between transmis-sion and storage cost. In this paper, we study the potential use of distributed source coding (DSC) in IMVS. Specifically, we propose two DSC constructions that could achieve good transmission-storage trade-offs. Central to these constructions is a method that can ef-ficiently encode the least significant bits (LSB) of a frame to be decoded, leading to competitive storage and transmission require-ments. Experiment results demonstrate these constructions compare favorably to existing tools, and could be valuable for interactive multiview streaming
