Claim:
1. A video decoding method, which is applied to a decoder end, comprising: acquiring N pieces of motion information of a target area according to motion-related information in a bitstream generated by an encoder end, wherein N is an integer greater than or equal to 2; performing a motion compensation operation on the target area separately by using each piece of motion information in the N pieces of motion information to obtain N predictions of the target area, wherein each prediction in the N predictions of the target area comprises predicted values of all sampling points in the target area; acquiring a prediction selection reference of the target area, wherein the prediction selection reference of the target area comprises values of all sampling points in a corresponding reference area of the target area; and determining a final prediction of the target area according to the N predictions of the target area and the prediction selection reference of the target area, wherein the target area consists of M basic prediction units, wherein M is greater than or equal to 2, wherein determining the final prediction of the target area according to the N predictions of the target area and the prediction selection reference of the target area comprises determining a final prediction of a selected basic prediction unit according to N predictions of the selected basic prediction unit and a prediction selection reference of the selected basic prediction unit, wherein each prediction in the N predictions of the selected basic prediction unit comprises predicted values of all sampling points in the selected basic prediction unit, wherein the prediction selection reference of the selected basic prediction unit comprises values of all sampling points of a basic prediction unit in a reference area of the target area, and wherein the basic prediction unit in the reference area of the target area is located at a same position as a basic prediction unit of the target area.
