A Selection Mechanism for Multiple Error Concealment Techniques in Scalable Video Coding

Abstract

To cope with the error problem for scalable video coding, this paper proposes a selection method of error concealment algorithms for whole frame loss in the enhancement layer. By analyzing the relationship between inter-layer and temporal domains, the proposed algorithm decides which error concealment algorithm adopted by H.264/SVC reference software is suitable for concealing the current erroneous macroblock in the enhancement layer. Through the proposed algorithm, different erroneous macroblocks can be properly concealed by different error concealment algorithms by considering the characteristics of each algorithm. Simulation results demonstrate that our proposed algorithm outperforms other error concealment algorithms in terms of PSNR and visual quality measurements.
