RICE PARAMETER DERIVATION FOR HIGH BIT-DEPTH VIDEO CODING - A simplified explanation of the abstract

  • This abstract for appeared for US patent application number 18345531 Titled 'RICE PARAMETER DERIVATION FOR HIGH BIT-DEPTH VIDEO CODING'

Simplified Explanation

The abstract describes a method used in video coding to determine shift values based on the dynamic range of neighboring transform coefficients. These shift values are then used to expand the possible values of a parameter used to convert a syntax element related to a transform coefficient into binary form. This method helps improve the efficiency of video coding by allowing for a wider range of values to be represented using fewer bits.


Original Abstract Submitted

A video coder determines of shift values based on the dynamic range of a sum of absolute values of neighboring transform coefficients. The shift value may then be used to extend possible values of a Rice parameter used to binarize a syntax element related to a currently coded transform coefficient.
