QUANTISATION BASED ON MODELLING OF TRANSFER SPEED DISTORTION, FOR CABAC CODERS Russian patent published in 2013 - IPC H04N7/46 H03M7/34 

Abstract RU 2475999 C2

FIELD: radio engineering, communication.

SUBSTANCE: method is proposed to quantise coefficients of a video block for a process of video coding, at the same time the method includes generation of many sets of quantised coefficients for a video block, in which every of sets of quantised coefficients is determined on the basis of an assumption that one specific coefficient of the video block coefficients corresponds to the last non-zero coefficient of the video block, assessment of many costs associated with coding of the video block with the help of CABAC, in which assessed costs accordingly are based on different some sets of quantised coefficients, and selection of this one of sets of quantised coefficients, associated with their lowest cost.

EFFECT: higher efficiency of coding a video signal supporting CABAC.
