OG exemplary drawing
AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 1-21 is confirmed.
1. An apparatus, comprising:
a video encoder for encoding a block in a picture using intra prediction by dividing pixels within the block into at least a first group and a second group and predicting pixels in the first group from neighboring pixels outside the block, prior to encoding the pixels in the second group,
wherein an intra prediction for at least one of the pixels within the second group is obtained by using pixels from neighboring pixels within the first group of pixels in blocks already coded and neighboring pixels outside the block that have already been coded, and
wherein the first group and the second group are predicted based on the spatial intra prediction mode of the current block being encoded.
