Abstract
A method for motion vector difference (MVD) coding of screen content video data is disclosed. In one aspect, the method includes determining an MVD between a predicted motion vector and a current motion vector and generating a binary string comprising n bins via binarizing the MVD. The method further includes determining whether an absolute value of the MVD is greater than a threshold value and encoding a subset of the n bins via an exponential Golomb code having an order that is greater than one in response to the absolute value of the MVD being greater than the threshold value.
