ALEXANDRIA, Va., July 16 -- United States Patent no. 12,671,814, issued on June 30.
"Entropy coding using pre-defined, fixed CDFS" was invented by Joseph Young (Mountain View, Calif.), In Suk Chong (Mountain View, Calif.) and Debargha Mukherjee (Cupertino, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Entropy coding a sequence of transform coefficients includes determining a predictor value corresponding to a transform coefficient, selecting a probability model from a set of pre-defined probability models based on the predictor value, and entropy coding a symbol associated with the transform coefficient using the selected probability model. The predictor value can be calculated based on a previous pr...
