Claim 0:
1. A method of decoding video data, the method comprising:
determining a color component of a unit of video data;
obtaining, for the unit of video data, a value of a multiple transform selection (MTS) index;
determining, 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 decoding, based on the determined value of the context increment 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
inverse-transforming, based on a transform indicated by the value of the LFNST index, transform coefficients of the unit of video data.
