Abstract :
H.264/AVC is the latest video coding standard from ITU-T and ISO/IEC. Not only the compression performance is enhanced but also the robustness of video bit streams to errors is better. FMO (Flexible Macro-block Ordering) is a new error resilient tool adopted by H.264/AVC and it has a good performance of error resilience. In this paper, a novel FMO algorithm is proposed, and an adaptive coding scheme based on this new FMO algorithm is introduced. Experiment results show that the proposed FMO algorithm could achieve almost the same PSNR as the FMO Type 1, but has better robustness in wireless transmission, and the adaptive coding scheme can still guarantee a high PSNR in the case of high packet loss rate.
