1. A method of decoding video data, the method comprising:
receiving a first slice header syntax element for a slice of the video data;
determining a first value for the first slice header syntax element, wherein the first value is indicative of whether dependent quantization is enabled for the slice;
receiving a second slice header syntax element for the slice of the video data;
determining a second value for the second slice header syntax element, wherein the second value is indicative of whether sign data hiding is enabled for the slice;
in response to one or both of the first value indicating that dependent quantization is enabled for the slice or the second value indicating that sign data hiding is enabled for the slice, determining that transform skip residual coding is enabled for the slice; and
decoding the slice based on the determinations.
