Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A method comprising: determining, by a processor in response to instructions stored on a non-transitory computer readable medium, whether to use a scaling list for a non-default quantization matrix to perform quantization of one or more units of video; identifying a plurality of transform unit sizes; determining a set of unavailable transform unit sizes from the plurality of transform unit sizes that are unavailable for performing a transform of the one…
