ABSTRACT:
A method and apparatus for concealing errors during decoding of a video bit stream utilize estimates, if possible, motion vectors in the temporal domain. If estimation in the temporal domain is not possible, motion vectors are estimated in the spatial domain. A macroblock is then estimated based upon the estimated motion vector. If estimation in the spatial domain is not possible, macroblock estimation is made without the use of an estimated motion vector.
