Cross-layer framework for real time H.264/AVC video transmission over wireless channels using outage probability

We present a framework for cross layer optimized real time transmission of H.264/AVC single layer video signals over wireless channels. In the proposed cross layer adaptation, the channel is characterized by the probability density function of its mutual information and the performance of the H.264/AVC encoder is modeled by a rate distortion model that takes into account the channel errors. This framework allows for direct adaptation to the conditions in the wireless channel. We show the effectiveness of the proposed framework in video transmission over Rayleigh fading channel, when channel distribution information is available at the transmitter.
