Abstract

Stereo video systems require double bandwidth and more than twice the computational complexity relative to mono-video systems. Thus, an efficient coding scheme is necessary for transmitting stereo video. We propose a novel stereo video coding system by exploiting a joint prediction scheme which combines three prediction schemes to achieve high coding efficiency and low computational complexity. Joint block compensation improves the visual quality. Motion vector prediction and mode pre-decision utilize the features of stereo video to reduce the computational complexity with up to 8-9 times acceleration. Experiments show that the proposed joint prediction scheme is 2 dB better than MPEG-4 TS and 3 dB better than MPEG-4 SP.
