Claim 3:
4. An apparatus, comprising:
a processor, configured to perform:
predicting a target pixel of a block of video data by applying weights to one or more of a plurality of reconstructed samples from one or more rows or columns neighboring the block of video data;
computing at least one intra prediction for the target pixel of the luminance block of video data as a function of predictions from one or more of the weighted predictions; and,
encoding the block of video using the prediction, wherein an index corresponding to a set of weights is assigned to sets of weights for applying said weights to a set of reference lines for all intra modes, and wherein sets of weights are assigned on a per block basis for luminance, and wherein chrominance uses a fixed set of weights for all blocks, and wherein reference lines used with a set of weights comprise reference lines not immediately adjacent to the block of video data.
