误差的补偿

Firstly, we suggest using context-free language to describe the start code string of MPEG-2 and using minimum-distance error-correcting parser to correct the errors in MPEG-2 start code string. This method hasn't been reported elsewhere. Secondly, side motion estimation rule is proposed for temporal error concealment and based on the rule, many new algorithms are proposed. Among which, the temporal error concealment method utilizing overlapped block motion compensation and side motion estimation rule has exceeded the best performance ever reported.
