METHOD, MEDIUM, AND SYSTEM ENCODING AND/OR DECODING MOVING PICTURES BY ADAPTIVELY APPLYING OPTIMAL PREDICTION MODES

摘要

A method, medium, and system decoding a moving picture. The moving picture decoding method may include decoing image information encoded in a bitstream, with the image information being encoded according to a prediction mode determined to be optimal for corresponding blocks of each color component of a corresponding current image, the method including restoring prediction mode information from the bitstream, the restored prediction mode information identifying the prediction mode, restoring residues that correspond to differences between the current image and a reference image for the current image, according to the prediction mode identified by the restored prediction mode information,generating a predicted image according to the prediction mode identified by the restored prediction mode information, and generating a restored image that corresponds to a sum of the generated residues and the generated predicted image.
