Abstract

A method and apparatus for determining a motion vector of a current block based on a motion vector of at least one block encoded/decoded before encoding/decoding of the current block, and prediction-encoding/decoding the current block based on one from among first-direction prediction, second-direction prediction, and bi-directional prediction, according to the determined motion vector.
