IMAGE ENCODER AND DECODER USING UNIDIRECTIONAL PREDICTION

摘要

The present invention relates to an image encoding and decoding technology and, more specifically, to an image encoding and decoding technology using unidirectional prediction. According to the present invention, provided is an image encoding method comprising the steps of determining a prediction mode for a macroblock; dividing the macroblock into a plurality of sub-blocks; and encoding the respective sub-blocks according to the prediction mode.
