Classification: CPC H | IPC H

Claim 14:
15. An apparatus comprising:
at least a memory and one or more processors, wherein the one or more processors are configured to:
encode picture data for at least a large block in a picture by determining that intra prediction is to be performed for the large block, wherein the large block has a large block size equal to or larger than 32×32, and the large block size is greater than a basic coding unit size, wherein the intra prediction is signaled for the large block and the one or more processors are configured to:
encode a binary split signaling syntax element specifying that the large block is further split into four equally sized sub-blocks;
encode an intra prediction mode for the large block that is not further split into four equally sized sub-blocks;
partition the large block into the four equally sized sub-blocks in response to the binary split signaling syntax element specifying that the large block is further split into four equally sized sub-blocks; and
encode 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.
