Performance Comparisons of Different Channel Codes in Distributed Video Coding

This paper introduces advanced channel codes turbo and LDPC to distributed video coding (DVC), and compares their performance in the whole system. From the simulation results, we can find that the LDPC codes are superior to turbo codes when the video sequence has high motion. Additionally, whether turbo or LDPC, the DVC system outperforms the conventional intra-frame coding though underperforms conventional motion-compensated inter-frame coding. But DVC has the advantage of easy encoding which can meet the demands of friendly up-linking media communication
