ABSTRACT:
Streamlined prediction approaches are provided to predict pixel values of a 4×4 subblock of a macroblock of video data being encoded, under a number of prediction modes. Additionally, prediction approaches are provided to predict pixel values of a non-4×4 M×N subblock of a macroblock of video data being encoded, under a number of prediction modes, including 8×8, 8×4 and 4×8 subblocks. The invention may be practiced in an encoder and/or a decoder of a video apparatus.
