Abstract
Concerning the video quality decline caused by damaged macroblocks in video transmission,this paper modified the boundary matching algorithm by adopting the interlaced weighted double error concealment scheme,inducted the motion vector estimation selectively,and used 8×8 subblocks correlation error concealment mode when the boundary matching error of the predictive block was higher than a given threshold.Experimental results show that the proposed algorithm could averagely raise the PSNR about 1 dB and correspondingly improve the decoded video quality effectively.
