摘要：
This paper presents an effective error concealment method for error-corrupted H.264/AVC video bitstreams over CDMA2000 (or UNITS) air interface. The proposed hybrid error concealment method performs selective error concealment depending on whether a lost macroblock is intra-coded or intercoded and whether it belongs to background or foreground. It is shown that under FMO coding mode of H.264/AVC, the proposed method increases PSNR gain up to 1.2dB compared to built-in algorithm in the H.264/AVC test model. In addition, the proposed algorithm shows better PSNR than other conventional error concealment algorithms.
