Claim:
1. An apparatus for determining a motion vector, the apparatus comprising at least one processor which implements: a parser configured to split a picture into a plurality of maximum coding units according to information about a maximum size of a coding unit, and obtain, from a bitstream, split information indicating whether to divide a coding unit into smaller coding units, in a maximum coding unit among the plurality of maximum coding units; and a decoder configured to determine at least one coding unit which is not split any more based on the split information, and determine partitions from the at least one coding unit, wherein the parser is configured to obtain, from the bitstream, information about a data area for parallel motion prediction and determine a data area using the information about a data area in a maximum coding unit among the plurality of maximum coding units, when the data area includes a current partition among the partitions and a neighboring block of the current partition, the decoder is configured to determine the neighboring block as an unavailable block, and perform inter prediction on the current partition using a motion vector of a block among motion vector prediction candidate blocks excluding the unavailable block, the neighboring block is previously decoded according to a decoding order and the current partition and the neighboring block are not included in one coding unit, when the split information indicates a non-split for a coding unit among the at least one coding unit which is not split any more, the decoder is configured to determine the partitions by dividing the coding unit, and perform inter prediction on the partitions, and when the split information indicates a non-split for a coding unit among the at least one coding unit which is not split any more, the decoder is configured to determine transformation units by dividing the coding unit, and perform inverse-transformation on the transformation units.
