摘要：

The characteristics and applicable situations of two common and effective error concealment methods were analyzed. An adaptive transmission error concealment algorithm for the enhancement layer in SNR scalable video coding (SVC) was proposed based on distortion estimation. The proposed algorithm estimates distortions resulted by the two concealment methods based on the correctly received reconstructed residue in the base layer and the difference between the quantization parameters of base and enhancement layers. The error concealment method resulting in a smaller distortion is selected to conceal the missing enhancement area for each 4×4 block. Simulation results of JVT SVC test model JSVM (joint scalable video model) show that average PSNR gains of 3.34 and 0.63 dB are achieved compared with the two commonly used error concealment methods, respectively.
