Abstract

This paper introduces an error concealment algorithm for P frame in video images that based on the error concealment algorithm in the reference software of H.264, which makes it extremely easy and flexible to obtain the best performance of error concealment at the decoder, and describes the theoretical foundation and realization in detail. External boundary matching algorithm (EBMA) based on calculate the difference of external nearby pixel between reference block and lost block which could better adapts to the characteristics of alterable blocks in motion estimation and improve the effect of error concealment of lost MB. The result of the proposed algorithm implemented on JM version 8.6 shows that have some advantages and practicality.
