ABSTRACT:
A method of motion compensation for an input block is disclosed. The method generally includes the steps of (A) generating a plurality of tap values in response to a motion vector for the input block, (B) generating an interpolated block by programmable filtering a reference block using the tap values, the interpolated block being spatially offset from the reference block by less than a half-pel separation and (C) generating an output block in response to the input block and the interpolated block.
