FIELD: video encoding and decoding.
SUBSTANCE: signalling a coding unit (CU) level enable flag and a transform unit (TU) level encoded luminance flag for an adaptive colour transform (ACT) encoded block. A method and device are provided for receiving video data, obtaining a CU, determining whether a CU flag is set to a predetermined flag state, determining whether a CU tree type is set to a predetermined tree type, determining whether an ACT flag should be signalled based on any from whether the CU flag is set to a predetermined flag state and whether the tree type of the CU is set to a predetermined tree type, and encoding video data based on whether the ACT flag is signalled.
EFFECT: increased efficiency of encoding.
