  Abstract

In this work. we propose a multi-hypothesis error concealment algorithm. which replaces a lost block with a weighted superposition of more than two reference blocks in previous frames. Three methods are developed to find the set of reference blocks and determine the weighting coefficients. These methods are implemented based on H.26L standard, and their performances are evaluated. It is shown that the proposed multi-hypothesis algorithm provides up to 1.5 dB better PSNR performance than the conventional single-hypothesis concealment algorithm.
