摘要：Embodiments of the present application disclose a motion vector predictionmethod and device for determining a motion vector predictor of a current block toimprove motion vector prediction efficiency. The method in the embodiment of thepresent application is Obtaining a reference frame corresponding to the motion vector ofthe current block, Determining a motion vector type of the motion vector of the currentblock based on a reference frame type of the reference frame; Obtaining a motion vectortype of a first motion vector of the at least one spatially adjacent prediction block whenthe at least one spatially adjacent prediction block of the current block is an inter-frameprediction block; , When the acquired motion vector type of the first motion vector is

different from all the motion vector types of the motion vector of the current block, themotion vector type is determined based on the decoding information of the spatiallyadjacent pixel blocks of the current block. Determining a second motion vector of anadjacent pixel block and using the second motion vector or a scaling value of the secondmotion vector as a candidate motion vector predictor for the current block.
