Regular coded bin reduction for coefficient coding

Abstract:

A video decoder can be configured to determine a size of a transform unit, wherein the transform unit comprises N coefficient groups and each coefficient group comprises M coefficients, wherein M and N are integer values; determine a regular bin count threshold for the transform unit based on the size of the transform unit; context decode syntax elements for the transform unit until the first number of regular coded bins is reached; in response to reaching the first number of regular coded bins, bypass decode additional syntax elements of the transform unit; determine values for a first set of coefficients of the transform unit based on the context decoded syntax elements; and determine values for a second set of coefficients of the transform unit based on the additional syntax elements.
