Compatible Stereo Video Coding with Flexible Prediction Mode

Stereo video can bring people into more vivid and actual sense, but the video data is too huge to storage and transmit conveniently. In this paper, a compatible scheme which compresses stereo video with flexible prediction structure is proposed. In the proposed scheme, we define a group of picture (GOP) considering of the real time of the video. There are different prediction structures according to temporal correlation and interview correlation whether the length of GOP is fixed. In any possible prediction structures, temporal correlations and interview correlations are utilized effectively. H.264 which is the most advanced video compression standard at present is utilized to improve the coding efficiency. The proposed scheme is compatible with the present equipments which are based on H.264 and process traditional monoview video. Therefore, the present equipments can process stereo video sequences conveniently. At last, the efficiency of the proposed scheme is proved by the experiment.
