Method and apparatus for improved signaling of motion vector difference
Abstract:
This disclosure relates generally to video coding and particularly to methods and systems for providing signaling schemes for motion vector difference. An example method for decoding a current video block of a video bitstream is disclosed. The method includes receiving a coded video bitstream; obtaining, from the coded video bitstream, a first motion vector difference (MVD) and a dynamic reference list (DRL) index for a current video block; deriving a second MVD for the current video block based on the first MVD; generating, by the device, a motion vector (MV) pair based on the first MVD, the derived second MVD, and a motion vector predictor (MVP) indicated by the DRL index; and decoding, by the device based on the MV pair, the current video block.
