Claim One:
1. A method performed by a combination of electronic circuitry components for coding a motion vector, the method comprising: from among blocks within a region of a first image, searching for a highest scoring match to a block of a second image, wherein searching for the highest scoring match includes penalizing scores of blocks outside a portion of the region without penalizing scores of blocks within the portion of the region, and wherein the portion of the region is less than an entirety of the region; coding the motion vector between the block of the second image and the highest scoring match; and in response to a scaled version of the motion vector, identifying a block of a third image as a match to a block of a fourth image; wherein: the third image is a higher resolution version of the first image; the fourth image is a higher resolution version of the second image; the portion of the region of the first image is spatially collocated with a cacheable portion of the third image if the first image is scaled up to size of the third image; the block of the second image is spatially collocated with the block of the fourth image if the second image is scaled up to size of the fourth image; and the cacheable portion of the third image is less than an entirety of the third image.
