Patent ID: 8391363

Claim:
A method for concealing a current block in a lost picture of a video sequence, comprising: 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; selecting one of the at least one block in the correctly received picture based upon an amount of overlap in the resultant projection; and concealing the current block in the lost picture using a motion vector of the selected one of the at least one block in the correctly received picture, wherein the method is performed in a video decoder, and wherein the at least one block in the correctly received picture includes a co-located block with respect to the current block in the lost picture and further includes spatially available neighboring blocks with respect to the co-located block, and the method further comprises reducing variation in motion vectors of the spatially available neighboring blocks in the correctly received picture in a post-processing stage subsequent to selecting the at least one block in the correctly received picture.
