摘要： Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. In some embodiments, the processing circuitry decodes prediction information of a current block in a current picture from a coded video bitstream. The prediction information is indicative of an inter prediction mode that signals a value associated with a motion vector difference in the coded video bitstream. The processing circuitry determines a precision for the motion vector difference based on a size of the current block, and converts the signaled value in the coded video bitstream to the motion vector difference based on the determined precision. Then, the processing circuitry determines a motion vector based on a prediction of the motion vector and the motion vector difference, and reconstructs at least a sample of the current block according to the motion vector.
