Claim 10:
11. A method of encoding picture data for at least a large block in a picture, the method comprising:
determining that intra prediction is to be performed for the large block, wherein the large block has a block size equal to or larger than 32×32, and the large block size is greater than a size of a basic coding unit;
encoding a binary split signaling syntax element specifying that the large block is further split into four equally sized sub-blocks;
encoding an intra prediction mode for the large block that is not further split into four equally sized sub-blocks;
partitioning the large block into the four equally sized sub-blocks in response to the decoded binary split signaling syntax element specifying that the large block is further split into four equally sized sub-blocks; and
encoding a second syntax element indicating a single spatial intra partition type for at least one basic coding unit sized sub-block, the single spatial intra partition type being determinable from among a plurality of spatial intra partition types.
