Classification: CPC H | IPC H

Claim 1:
2. A method of encoding a motion vector, the method comprising:
generating information regarding a predetermined integer number n, wherein the information is included in at least one of a sequence parameter set (SPS), a picture parameter set (PPS), and a slice header;
generating a flag indicating whether a prediction mode of a current prediction unit is a merge mode which uses a motion vector included in merge motion vector candidates;
obtaining merge motion vector candidates by using a motion vector of a temporally neighboring prediction unit that is temporally related to the current prediction unit and motion vectors of spatially neighboring prediction units that are spatially related to the current prediction unit when the prediction mode of the current prediction unit is determined as the merge mode;
when a number of motion vectors included in the obtained merge motion vector candidates is smaller than n−1, adding a plurality of zero vectors to the obtained merge motion vector candidates so that the number of motion vectors included in the merge motion vector candidates reaches the predetermined integer number n; and
generating an index indicating a motion vector from among the n motion vectors included in the merge motion vector candidates,
wherein the spatially neighboring prediction units comprise a spatially neighboring prediction unit located on a lower left side of the current prediction unit.
