A method of decoding video data including, receiving a first block of video data, receiving a first syntax element indicating if a coding mode is to be used for the first block of video data in the case that the first block of video data is associated with a number of non-zero transform coefficients greater than or equal to a threshold, explicitly decoding a value of the received first syntax element, and applying the coding mode to the first block of video data in accordance with a value of the first syntax element.
