FIELD: video encoding and decoding.
SUBSTANCE: inter-component linear model (CCLM) is calculated during conversion between the current video block of visual media and the bit stream representation of the current video block and/or a chroma residual scaling factor (CRS) for the current video block based at least in part on adjacent samples of the corresponding luma block, which covers upper left sample of combined brightness unit associated with current video unit, wherein to identify the corresponding brightness unit one or more characteristics of the current video unit are used.
EFFECT: high efficiency of video compression.
