Abstract: Video is more and more popular as the most important part of the multimedia information,but in the error-prone channels ,channel errors can not only damage current frame, but also propagate to subsequent frames, which can significantly degrade the image quality. Error concealment provides a feasible solution for error handling,H.264 SVC incorporates efficiently the functionalities of scalability of temporal,spatial and quality as well as the good encoding performance as the SVC extension of the H.264 standard.Therefore,it is a promising technique in theory and practice to design error concealment methods based on H.264 SVC. A improved algorithm is proposed on the basis of the BLSKIP algorithm.In this article, the improved temporal concealment TD algorithm is combined with the BLSKIP algorithm based on that if the base layer loses ,and adpatively chooses the appropriate concealment mode to improve the error resilience ability for the enhancement layer consumer applications.Experiment and comparison with other SVC error concealment algorithms shows that from the subjective and objective quality our proposed algirithm could both effectively recover the video quality。
