Abstract
A method and apparatus for encoding/decoding motion vector information are provided, in which a coding unit is divided into a plurality of subunits, PMVs of the subunits are calculated, it is determined whether the PMVs satisfy a predetermined condition, and coded motion vector data are generated, which include information indicating an omission of the motion vectors of the subunits, if the PMVs satisfy the predetermined condition.
