摘要

There are provided a method and apparatus for block-based error concealment. The apparatus includes an error concealment module for concealing a current block in a lost picture of a video sequence by projecting positions of at least one block in a correctly received picture of the video sequence to a position of the current block in the lost picture using motion vectors of the at least one block in the correctly received picture so as to obtain a resultant projection, and selecting one of the at least one block in the correctly received picture based upon an amount of overlap in the resultant projection. The current block in the lost picture is then concealed using a motion vector of the selected one of the at least one block in the correctly received picture.
