A device for coding video data includes a video coder configured to: determine for a chroma transform block (TB) a sub-sampling format for the chroma TB; based on the sub-sampling format for the chroma TB, identify one or more corresponding luma TBs; determine, for each of the one or more corresponding luma TBs, if the corresponding luma TB is coded using a transform skip mode; and, based on a number of the one or more corresponding luma TBs coded using the transform skip mode being greater than or equal to a threshold value, determine that the chroma TB is coded in the transform skip mode. |
