1. A method for concealing errors in video data, comprising: decoding a first set of motion vectors in a corrupted video packet; estimating a second set of remaining motion vectors in the corrupted video packet; performing motion compensated temporal replacement of texture data using said first and second sets of motion vectors; evaluating image smoothness of the texture data; repeating said decoding, estimating, performing, and evaluating with one less motion vector in the first set and one more motion vector in the second set, said repeating done until there is no more motion vector left in the first set; and selecting sets of motion vectors from said first and second sets to replace motion vectors in said corrupted video packet, where said sets of motion vectors produce a best image smoothness measure of said texture data.
