Abstract
A digital video signal decoding apparatus has a memory for storing motion vectors which have been decoded by a decoder, and a motion vector calculating circuit for calculating a presumed motion vector from the motion vectors stored in the memory, whereby, even if part of a bit stream has been lost and each of pixel blocks which have been lost accordingly cannot be decoded, each of the lost pixel blocks is filled in by a corresponding pixel block in a preceeding frame which has been motion-compensated through a motion compensation circuit by using the presumed motion vector, thereby preventing degradation of the picture quality at that pixel block portion.
