Robust Error Resilient H.264 AVC Video Coding-Chung
IEEE TENCON 2013——This talk proposes an error resilient video coding algorithm in H.264/AVC for packet-loss networks, which involves an inter frame prediction scheme and a joint source-channel rate-distortion optimization (RDO) function for both inter mode decision and motion estimation. The suggested inter frame prediction and joint source-channel RDO function can significantly reduce the error propagation effect and improve decoded video quality in error-prone wireless networks. The experimental results reveal that average PSNR gain of 10 dB cab be achieved for the proposed algorithm in error-prone wireless networks. The results also reveal that average gain of 2dB can be achieved when compared with other distinct algorithms.
