Abstract:
A method and apparatus for processing a video block extracted from an encoded bitstream. The method generally includes the steps of (A) generating a normal block by inverse transforming the video block, the normal block having a normal resolution, (B) generating an alternate block from the video block, the alternate block comprising image detail (i) present after the inverse transforming and (ii) absent from the normal block and (C) generating an output block based on the normal block and the alternate block, the output block having an output resolution greater than the normal resolution.
