Claim 9:
10. A method of encoding video data, the method comprising:
selecting, from a plurality of low-frequency non-separable transforms (LFNSTs), a LFNST having an LFNST index;
transforming, using the LFNST, transform coefficients of a unit of video data;
determining a color component of the 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 the LFNST index for the unit of video data; and
CABAC encoding, 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.
