Error concealment protection for loss resilient bitplane-coded video communications
In this paper, we propose an error control scheme for video communications over lossy channels. The proposed algorithm uses error concealment protection (ECP) approach to coordinate with multiple encoded streams which is capable of handling error concealment to achieve robust transmissions. Unlike previous methods, our algorithm focuses on joint optimizing multiple substreams distortion with concealment over error prone channels. The algorithm minimizes the expected rate-distortion function to achieve the optimal FEC result. In the experiments, we demonstrate the effectiveness of our method by using a 3-D SPIHT algorithm. Simulation results show that the proposed protection strategy achieves about 2 dB higher peak signal-to-noise ratio compared to conventional method
