Coding data using an enhanced context-adaptive binary arithmetic coding (CABAC) design
A video coding device includes a memory configured to store video data and processor(s) configured to process at least a portion of the stored video data. The processor(s) are configured to identify a coefficient group (CG) that includes a current transform coefficient of the video data, the CG representing a subset of transform coefficients within a transform unit. The processor(s) are further configured to determine a size of the CG based on a combination of a transform size and one or both of (i) a coding mode associated with the transform unit, or (ii) a transform matrix associated with the transform unit.
