Claim 10:
11. A non-transitory computer-readable digital storage medium which stores a bitstream generated by a method, the method comprising:
deriving prediction samples for a current block;
deriving residual samples for the current block based on the prediction sample;
deriving transform coefficients by applying at least one of LFNST and MTS for the residual samples; and
encoding residual information related to the transform coefficients and at least one of an LFNST index related to an LFNST kernel and an MTS index related to an MTS kernel to generate the bitstream,
wherein the LFNST index is encoded before the MTS index, and
wherein the MTS index is encoded based on a value of the LFNST index.
