Classification: CPC H | IPC H

Claim 9:
10. An inter prediction apparatus, comprising:
one or more processors; and
a non-transitory computer-readable storage medium in communication with the one or more processors and storing instructions, which when executed by the one or more processors, cause the one or more processors to:
obtain a motion vector predictor of a current picture block;
obtain an index value of a length of a motion vector difference of the current picture block, wherein the motion vector difference of the current picture block is used to indicate a difference between the motion vector predictor and a motion vector target value of the current picture block;
determine target length information from a set of candidate length information based on the index value of the length, wherein the set of candidate length information comprises candidate length information of N motion vector differences, and N is a positive integer greater than 1 and less than 8;
obtain the motion vector difference of the current picture block based on the target length information;
determine the motion vector target value of the current picture block based on the motion vector difference of the current picture block and the motion vector predictor of the current picture block; and
obtain a prediction block of the current picture block based on the motion vector target value of the current picture block.
