The paper presents a new selective temporal error concealment algorithm (STEC) for error-corrupted H.264/AVC video bitstreams over the cdma2000 (or UMTS) air interface. The proposed algorithm performs selective temporal error concealment depending on whether a lost MB (macroblock) is in the background or foreground. It is shown that under the FMO coding mode of H.264/AVC, the proposed algorithm provides PSNR gain up to 1.18dB compared to the algorithm built into the H.264/AVC test model. In addition, the proposed STEC has an average PSNR improvement of 0.33dB compared with that under the N slice coding mode.
