Statistical multiplexing of video programs

In this work, we propose new R-D models for the SM system using H.264/AVC video encoders. These models take into account the interframe dependencies used for performing motion compensation between a reference and a predicted frame, even I and P frames or P and P frames. In this article, the dependencies specified in terms of impact of encoding parameters of a given frame over the next one is proved experimentally and interpreted theoretically by considering the quantization of an IRS-AR source model with varying QPs. Theoretical R-D curves obtained for this model show a behavior similar to the curves obtained using H.264/AVC video coder. Encouraging results have been obtained, but the proposed model still needs to be refined to be used within an SM.
