Abstract:
1. A method of decoding motion information, the method comprising: obtaining, by a decoder comprising a processor, a spatial motion vector predictor candidate of a current prediction unit by using a motion vector of an available spatial prediction unit spatially related to the current prediction unit; obtaining a temporal motion vector predictor candidate of the current prediction unit by using a motion vector of an available temporal prediction unit temporally related to the current prediction unit; adding, when a number of the spatial motion vector predictor candidates and the temporal motion vector predictor candidates is smaller than a predetermined number n, where n is an integer equal to two or greater, a zero vector to be a motion vector predictor candidate so that a number of motion vector predictor candidates is to be the predetermined number n; obtaining information to determine a motion vector predictor among the motion vector predictor candidates, from a bitstream; and obtaining the motion vector predictor of the current prediction unit based on the information.
