ABSTRACT:
A simplified-in-structure vertical interpolator for compressed video data down-loaded from image memory to an odd-line line storage memory and an even-line line storage memory is followed in cascade by a horizontal interpolator. The horizontal interpolator calculates the difference between adjoining pixels in horizontally compressed video data from the vertical interpolator, divides the difference by the horizontal compression ratio and accumulates the divided differences during line trace intervals to recover de-compressed video data.
