FIELD: video encoding.
SUBSTANCE: residual block for the current video data block is logically output according to the type of segmentation tree into a plurality of residual subblocks. Based on the determined segmentation of the residual block into a plurality of residual subblocks, transform kernel transformation types for the plurality of residual subblocks in at least one of a horizontal direction or a vertical direction are determined. A stream of bits is encoded as a coded representation of video data that carries in signaling signals information indicating whether or not a residual block is segmented, and further signaling in signaling signals information indicating the type of segmentation tree for the residual block that is segmented, wherein information indicating the type of the segmentation tree is associated only with the residual block.
EFFECT: increased efficiency of video encoding.
