Method and Apparatus for Signaling Predicted Motion Vector Difference Values

원문 (중국어)

A decoder receives, from a bitstream for a current block, a first indication of whether a magnitude symbol of a motion vector difference (MVD) is enabled to be selected for coding as an indication of whether the magnitude symbol is equal to a corresponding magnitude symbol of an MVD predictor. The decoder determines, based on the first indication, whether to skip parsing a second indication from the bitstream. The second indication indicates whether an absolute value of a component of the MVD is greater than one. The decoder receives, from the bitstream, one or more symbols of the component of the MVD. The decoder determines a value of the component of the MVD based on the one or more symbols and the determining whether to skip parsing the second indication. The decoder reconstructs the current block based on the MVD.
