PIXEL-BY-PIXEL WEIGHTING FOR INTRA-FRAME CODING

Techniques for efficiently signaling one or more prediction modes for blocks in a macroblock. A mode uniformity indicator is provided for each macroblock to indicate whether all blocks in the macroblock are to be predicted using the same prediction mode.

Summary:Techniques for efficiently signaling one or more prediction modes for blocks in a macroblock. A mode uniformity indicator is provided for each macroblock to indicate whether all blocks in the macroblock are to be predicted using the same prediction mode. In an embodiment, an encoder signals a mode uniformity indicator and a prediction mode. In another embodiment, a decoder receives a mode uniformity indicator and a prediction mode, and predicts at least two blocks of the macroblock using the prediction mode if the mode uniformity indicator is true.
