Joint Adaptive Intra Refreshment and Unequally Error Protection Algorithms for Robust Transmission of H.264/AVC Video

In this paper, we propose an efficient intra refreshment algorithm, which can achieve both the global optimization in determining the intra refreshing ratio and the local accuracy in selecting the proper macroblocks to be intra coded before the current frame is actually encoded. Furthermore, incorpo...

Summary:In this paper, we propose an efficient intra refreshment algorithm, which can achieve both the global optimization in determining the intra refreshing ratio and the local accuracy in selecting the proper macroblocks to be intra coded before the current frame is actually encoded. Furthermore, incorporated with our proposed intra refreshment algorithm, an effective UEP scheme based on a dynamic FMO mapping mode is also proposed in this paper to better protect the intra macroblocks in a frame. The experimental results show that our joint intra refreshment and UEP algorithm can remarkably improve the reconstructed video quality in the packet lossy network
