AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
Claims 1, 12, 23, 34 and 45 are determined to be patentable as amended.
Claims 2-11, 13-22, 24-33 and 35-44, dependent on an amended claim, are determined to be patentable.
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 the pixels in the first group using intra planar prediction from neighboring pixels outside the block in a first way, prior to encoding the pixels in the second group,
wherein an intra planar prediction for at least one of the pixels within the second group is obtained in a second way, different than the first way, and based on at least one of pixels within the first group [ that have already been coded ] and neighboring pixels outside the block that have already been coded, and
wherein the first group and the second group are part of a same block that is contained within a macroblock.
12. In a video encoder, a method, comprising:
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 the pixels in the first group using intra planar prediction from neighboring pixels outside the block in a first way, prior to encoding the pixels in the second group,
wherein an intra planar prediction for at least one of the pixels within the second group is obtained in a second way, different than the first way, and based on at least one of pixels within the first group [ that have already been coded ] and neighboring pixels outside the block that have already been coded, and
wherein the first group and the second group are part of a same block that is contained within a macroblock.
23. An apparatus, comprising:
a video decoder for decoding 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 the pixels in the first group using intra planar prediction from neighboring pixels outside the block in a first way, prior to decoding the pixels in the second group,
wherein an intra planar prediction for at least one of the pixels within the second group is obtained in a second way, different than the first way, and based on at least one of pixels within the first group [ that have already been decoded ] and neighboring pixels outside the block that have already been decoded, and
wherein the first group and the second group are part of a same block that is contained within a macroblock.
34. In a video decoder, a method, comprising:
decoding 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 the pixels in the first group using intra planar prediction from neighboring pixels outside the block in a first way, prior to decoding the pixels in the second group,
wherein an intra planar prediction for at least one of the pixels within the second group is obtained in a second way, different than the first way, and based on at least one of pixels within the first group [ that have already been decoded ] and neighboring pixels outside the block that have already been decoded, and
wherein the first group and the second group are part of a same block that is contained within a macroblock.
45. A non-transitory computer readable storage media having video signal data encoded thereupon, comprising:
a block in a picture encoded using intra prediction by dividing pixels within the block into at least a first group and a second group and predicting the pixels in the first group using intra planar prediction from neighboring pixels outside the block in a first way, prior to encoding the pixels in the second group,
wherein an intra planar prediction for at least one of the pixels within the second group is obtained in a second way, different than the first way, and based on at least one of pixels within the first group [ that have already been coded ] and neighboring pixels outside the block that have already been coded, and
wherein the first group and the second group are part of a same block that is contained within a macroblock.
