Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 12:
13. A video picture decoder, comprising:
a memory and a processor, wherein the memory stores a computer program which is runnable on the processor; and the processor is configured to, when executing the program, perform the following:
parse a bitstream to obtain a position of a current block in a video picture;
determine first motion information and second candidate motion information according to the position, wherein the motion information at least comprises motion vectors;
judge, with the second candidate motion information pre-determined, whether a distance between the motion vector of the first motion information and the motion vector of the second candidate motion information is greater than a non-zero first threshold value; when a judgment result indicates that the distance is less than or equal to the first threshold value, obtain second motion information based on the second candidate motion information; when the judgment result indicates that the distance is greater than the first threshold value, take the second candidate motion information as the second motion information, wherein the distance is determined based on a first position to which the motion vector of the first motion information points and a second position to which the motion vector of the second candidate motion information points; and
construct an inter prediction value of the current block by using the first motion information and the second motion information.
