Abstract: The present invention relates to an image encoding and decoding technique, and more particularly, to an image encoder and decoder using unidirectional prediction. The image encoder includes a dividing unit to divide a macro block into a plurality of sub-blocks, a unidirectional application determining unit to determine whether an identical prediction mode is applied to each of the plurality of sub-blocks, and a prediction mode determining unit to determine a prediction mode with respect to each of the plurality of sub-blocks based on a determined result of the unidirectional application determining unit.

Abstract: Provided is a data transmission system for transmitting data using a relay. The relay selects a transmission terminal from among a plurality of terminals connected to the base station. During the first time slot, the base station transmits base station data to the relay, and the transmission terminal transmits terminal data to the relay. During the second time slot, the relay transmits the terminal data to the base station and the base station data to the transmission terminal.
