Original Abstract Submitted
This disclosure relates generally to video coding/decoding and particularly for implicitly indicating motion vector predictor precision. One method includes receiving a coded video bitstream; determining, based on the coded video bitstream, a current block of a current frame to be inter predicted by at least one reference block of at least one reference frame; determining, based on the coded video bitstream, a motion vector (MV) of the current block to be predicted by a motion vector predictor (MVP) and a corresponding motion vector difference (MVD); determining an MVP precision according to an implicit indication, a pre-defined rule, or a high-level syntax, wherein an MVD precision associated with the corresponding MVD is different from the MVP precision; and reconstructing, by the device, the current block based at least on the MVP at the determined MVP precision and the MVD at the MVD precision that is different from the MVP precision.
