Abstract
In one embodiment, a method determines when a scaling list for a non-default quantization matrix is being used to perform quantization of one or more units of video. Transform unit sizes are determined that are not available for performing a transform of the one or more units of video. Then, the method encodes or decodes scaling list data for each of the transform unit sizes available for performing the transform of the one or more units of video. The scaling list data is for transform unit sizes not available for performing the transform of the one or more units of video are not encoded or decoded.
