Claim 17:
18. A device for coding video data, the device comprising:
a memory; and
one or more processors implemented in circuitry and configured to:
determine a color component of a unit of video data;
obtain, for the unit of video data, a value of a multiple transform selection (MTS) index;
determine, based at least on the color component and the value of the MTS index, a value of a context increment (ctxInc) for context-adaptive binary arithmetic coding (CABAC) a syntax element that specifies a value of a low-frequency non-separable transform (LFNST) index for the unit of video data;
CABAC code, based on the determined context and via a syntax structure for the unit of video data, the syntax element that specifies the value of the LFNST index for the unit of video data; and
transform, based on a transform indicated by the value of the LFNST index, transform coefficients of the unit of video data.
