Abstract

An encoding method and apparatus and a decoding method and apparatus for determining a motion vector of a current block (1010) based on a motion vector of at least one previously-encoded or previously-decoded block are provided. The decoding method includes: decoding (1610) information regarding a prediction direction from among a first direction, a second direction, and bi-directions, and information regarding pixel values of the current block; determining (1620) the prediction direction in which the current block is to be predicted, based on the decoded information regarding the prediction direction, and determining a motion vector for predicting the current block in the determined prediction direction; and restoring (1630) the current block, based on the determined motion vector and the decoded information regarding the pixel values, wherein the first direction is a direction from a current picture (1110) to a previous picture (1112), and the second direction is a direction from the current picture to a subsequent picture (1114).
