Patent attributes
In some examples, an apparatus for video decoding includes processing circuitry. The processing circuitry decodes prediction information of a current block from a coded video bitstream. The prediction information is indicative of an inter prediction mode that performs inter prediction based on a motion vector predictor selected from a list of candidates and a motion vector difference. Then, the processing circuitry decodes precision information of the motion vector difference and derives the motion vector predictor from a subset of the list of candidates when the precision information is indicative of a specific precision. Then, the processing circuitry reconstructs a sample of the current block according to the motion vector predictor and the motion vector difference.
