Abstract
Official abstract text for this publication.
Methods, systems, and computer program products are provided to divide code blocks, such as blocks of quantized coefficient of image or video data, into smaller blocks and sub-blocks that can be processed in parallel using layered entropy coding and decoding scheme. This division is accomplished while still encoding the entire code block using the same layered entropy coding scheme.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: dividing a code block into a plurality of pixel groups; for a pixel group from the plurality of pixel groups, analyzing a first cluster pattern from a plurality of cluster patterns in a layered encoding scheme for the code block, wherein the first cluster pattern arranges the pixel group into sub-blocks, and wherein the analyzing comprises: calculating maximum code sizes for encoding the sub-blocks according to the layered encoding s…
