Abstract
A video encoding apparatus for predicting a motion vector of a current block to be encoded is to determine one or more representative blocks from neighboring blocks of the current block according to priorities of the neighboring blocks; and encode the motion vector of the current block by using, as a predicted motion vector of the current block, a first motion vector selected from motion vectors of the determined one or more representative blocks and a second motion vector of at least one block within a reference picture.
