Claim 19:
20. The non-transitory computer-readable recording medium of claim 18, wherein whether the transform skip residual coding syntax structure is disabled for the residual samples of the first video unit is further based on whether a dependent quantization is used for the first video unit, and wherein in the dependent quantization, a set of admissible reconstruction values for a transform coefficient depends on values of the transform coefficient levels that precede a current transform coefficient level in reconstruction order, and
wherein the rule specifies that for a second video unit of the video, when the second video unit is not coded with the transform skip mode or the transform skip residual coding syntax structure is disabled for residual samples of the second video unit, a non-transform-skip residual coding syntax structure is used for the second video unit; otherwise, the transform skip residual coding syntax structure is used for the second video unit.
