1. A method used in coding video image data, comprising the steps of: (a) providing a region of a first image, wherein said region abuts a boundary of said first image; (b) providing a non-zero motion vector corresponding to a block of a second image, said block being larger than said region; (c) estimating a first portion of said block by moving said region in accordance with said non-zero motion vector; and (d) displaying said block of said second image, wherein said step (b) comprises the steps of: (1) providing said first and second images; (2) selecting said block of said second image; (3) analyzing said first image to identify said region of said first image as corresponding to said block; and (4) generating said non=zero motion vector corresponding to a relative vector distance between said region and said block.
