Claim 6:
7. 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 pixels in the first group decoding prior to decoding the pixels in the second group,
wherein the first group and the second group are responsive to a spatial intra prediction mode of the block, and
a prediction mode for at least one of the pixels within the rest of the block is obtained by using pixels within the first group and in neighboring blocks already decoded.
wherein image data for the block is decoded from a bitstream, and a grouping method used to form the first and the second groups of pixels is explicitly determined from the bitstream.
