CPC H04N 19/119 (2014.11) [H04N 19/463 (2014.11); H04N 19/96 (2014.11)] | 3 Claims |
1. A method of partitioning video data for video coding, the method comprising:
determining whether each of partitioning modes for a video block is allowed depending on a block size, an allowed minimum size, and a depth of a current coding unit,
wherein the partitioning modes includes a quadtree partitioning, a horizontal symmetric binary tree partitioning, a vertical symmetric binary tree partitioning, a horizontal triple tree partitioning, and a vertical triple tree partitioning;
determining whether a subsequent partitioning for a subsequent block is allowed based on a parent partition,
wherein, in a case that the subsequent block is a central node resulting from the vertical triple tree partitioning, a subsequent quadtree partitioning and a subsequent vertical symmetric binary tree partitioning are disallowed;
signaling bin values corresponding to allowed partitioning modes, wherein signaling the bin values includes determining a context index for a bin value indicating the quadtree partitioning based on at least whether a quadtree depth of a left neighboring video block is greater than a quadtree depth of the video block and whether a quadtree depth of an above neighboring video block is greater than the quadtree depth of the video blocks.
