FIELD: physics.
SUBSTANCE: invention relates to encoding and decoding, in particular to signalling a coding unit (CU) level enable flag and a transform unit (TU) level coded luma flag for an adaptive colour transform (ACT) mode coded block. Disclosed is a method and a device for obtaining video data, obtaining a CU block, determining whether the CU block flag is set to a predetermined flag state, determining whether the CU block tree type is set to a predetermined tree type, determining whether to signal the ACT flag based on any of whether the CU block flag is set to a predetermined flag state and whether the CU block tree type is set to a predetermined tree type, and encoding the video data based on whether the ACT flag is signalled.
EFFECT: high coding efficiency.
