9 Claims

1. A method of processing video data in a video coding system, comprising:

receiving input data associated with a current block in a current slice;

determining whether one or more components of the current block satisfy one or more predefined criteria during partitioning;

applying a mode constraint to the current block only if the one or more components of the current block satisfy the one or more predefined criteria, wherein the mode constraint restricts all blocks within the current block to be processed by a same prediction mode when the current block is split into a plurality of blocks;

adaptively splitting the current block into one or more blocks;

signaling or parsing one or more prediction mode syntax elements of a first block in the current block according to a constrained mode of the current block when the one or more components of the current block satisfy the one or more predefined criteria; and

encoding or decoding the current block with the mode constraint when the one or more components of the current block satisfy the one or more predefined criteria or encoding or decoding the current block without the mode constraint when the one or more components of the current block do not satisfy the one or more predefined criteria.
