Claim 6:
7. A non-transitory computer-readable medium for storing data associated with a video signal, comprising:
a data stream stored in the non-transitory computer-readable medium, the data stream comprising:
information on a residual coefficient of a current transform block,
wherein a residual sample of the current transform block is obtained by performing inverse-transform for an inverse-quantized residual coefficient of the current transform block,
wherein the inverse-transform is performed based on a transform type set of the current transform block, and
wherein, in response to a case where a coding block including the current transform block is partitioned into two transform blocks, the transform type set of the current transform block is determined differently between when the coding block is partitioned in a horizontal direction and when the coding block is partitioned in a vertical direction, and
wherein the coding block is obtained based on a tree-based block division including at least one of a quad division or a binary division.
