Abstract
Official abstract text for this publication.
Coefficient coding for transform units (TUs) during high efficiency video coding (HEVC), and similar standards, toward simplifying design while enhancing efficiency. Elements of the invention include coefficient coding for TUs with up-right diagonal scans being modified, and selectively applying multi-level significance map coding.
First claim
Opening claim text (preview).
What is claimed is: 1. A system of encoding and decoding video signals, comprising: (a) a video encoder having a computer processor configured for encoding of video frames; and (b) programming executable on said computer processor for: (i) performing intra-prediction based on neighboring reconstructed values, and/or inter-prediction on said video frames based on motion-estimation and motion-compensation; (ii) executing a transform based on said intra-prediction and/or inter-p…
