Claim 1:
2. An apparatus for decoding a picture, the apparatus comprising:
a non-transitory memory storage comprising instructions; and
at least one processor communicatively coupled to the non-transitory memory storage, wherein the at least one processor is configured to execute the instructions to:
determine that a temporal candidate is available when a size of a current block is greater than or equal to a predetermined size;
determine whether one neighboring block spatially adjacent to the current block in a current picture is available;
obtain a temporal motion vector by using a motion vector of the one neighboring block when the one neighboring block is available, wherein when the one neighboring block is not available, the temporal motion vector is determined as a zero vector;
dividing the temporal motion vector by a predetermined value;
generate a candidate list comprising the temporal candidate when the temporal candidate is available; and
when the temporal candidate is selected from among candidates included in the candidate list:
determine a motion vector of a first sub-block in the current block, the motion vector of the first sub-block being determined based on a motion vector of a first sub-block in a predetermined picture;
determine a motion vector of a second sub-block in the current block, the motion vector of the second sub-block being determined based on a motion vector of a second sub-block in the predetermined picture; and
reconstruct the current block by using the motion vector of the first sub-block in the current block and the motion vector of the second sub-block in the current block,

wherein the first sub-block in the predetermined picture and the second sub-block in the redetermined picture are determined based on the divided temporal motion vector.
