In one example, a device for coding video data includes a video coder, such as a video encoder or a video decoder, that is configured to code information indicative of whether a transform unit of the video data is square or non-square, and code data of the transform unit based at least in part on whether the transform unit is square or non-square. In this manner, the video coder may utilize non-square transform units. The video coder may be configured to use non-square transform units for certain situations, such as only for chrominance or luminance components or only when a corresponding prediction unit is non-square. The video coder may further be configured to perform an entropy coding process that selects context for coding data of the transform unit based on whether the transform unit is square or non-square. |
