Patent ID: 11736708

Abstract:
Aspects of the disclosure include methods, apparatuses, and non-transitory computer-readable storage mediums for video encoding/decoding. An apparatus includes processing circuitry that decodes prediction information of a coding unit in a video bitstream. The processing circuitry determines whether a luma block and a chroma block associated with the coding unit have different partitioning trees based on the prediction information. When the luma block and the chroma block have different partitioning trees, the processing circuitry determines whether the luma block is coded in intra block copy (IBC) mode based on a first IBC flag included in the prediction information. The processing circuitry determines whether the chroma block is coded in the IBC mode based on one of the first IBC flag, a second IBC flag included in the prediction information, and a default mode. The processing circuitry reconstructs the current coding unit based on the luma block and the chroma block.
