SYSTEMS AND METHODS FOR SCALABLE THROUGHPUT ENTROPY CODERS - A simplified explanation of the abstract

• This abstract for appeared for US patent application number 18336877 Titled 'SYSTEMS AND METHODS FOR SCALABLE THROUGHPUT ENTROPY CODERS'

Simplified Explanation

This abstract describes a method for decoding image content from an encoded bitstream. The method involves dividing a block of image content into single samples and sample groups, and then decoding each of these samples using different coding techniques. The decoded samples are then concatenated into a block of residuals, which is used to reconstruct the image content based on neighboring blocks and the residuals.

Original Abstract Submitted

A method for decoding image content from an encoded bitstream including a plurality of blocks includes: dividing a block including one or more components of the image content into N single samples and M sample groups corresponding to one of the components, where N and M are greater than or equal to one; decoding each of the N single samples using a symbol variable length code to generate one or more decoded single samples; decoding each of the M sample groups using a common prefix entropy code to generate one or more decoded sample groups, each of the M sample groups including a variable length prefix and one or more fixed length suffixes representing a plurality of samples; concatenating the decoded single samples and the decoded sample groups into a block of residuals; and reconstructing image content based on previously reconstructed neighboring blocks and the block of residuals.
