Claim Text:
1. A method of determining a motion vector, the method comprising: splitting a picture into a plurality of maximum coding units according to information about a maximum size of a coding unit; obtaining, 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; when the split information for a current depth indicates a split, splitting a coding unit of the current depth into coding units of a lower depth, independently from neighboring coding units; when the split information for the current depth indicates a non-split, determining at least one partition for prediction from the coding unit of the current depth; obtaining, from the bitstream, information about a data area for parallel motion prediction, in a maximum coding unit among the plurality of maximum coding units; determining a data area using the information about a data area; when the data area includes a current partition among partitions and a neighboring block of the current partition, determining the neighboring block as an unavailable block; and generating a motion vector of the current partition using a motion vector of a block among motion vector prediction candidate blocks excluding the unavailable block, wherein 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, and when the split information for the current depth indicates a non-split, transformation units are determined by dividing the coding unit of the current depth, and inverse-transformation is performed on the transformation units.
