VIDEO CODING USING ADAPTIVE MOTION VECTOR RESOLUTION Russian patent published in 2016 - IPC H04N19/517 H04N19/13 

FIELD: information technology.

SUBSTANCE: method for entropy video data coding comprises, when an absolute value of an x-component of a motion vector difference value for a current block is greater than zero and when an absolute value of a y-component of the motion vector difference value for the current block is greater than zero, entropy coding information representing the motion vector difference value, wherein the entropy coding of information representing the motion vector difference value comprises: interleaving information representing whether or not the said absolute value of the x-component of the motion vector difference value for the current block of video data is greater than zero and information representing whether or not the said absolute value of the y-component of the motion vector difference is greater than zero, and interleaving information representing whether the absolute value of the x-component of the motion vector difference value, information representing the absolute value of the y-component of the motion vector difference, the sign of the x-component of the motion vector difference value and the sign of the y-component of the motion vector difference.

EFFECT: providing collaborative coding of motion vector difference values.
