    Abstract: A method and an apparatus for encoding a moving picture, and a method and an apparatus for decoding the moving picture are provided to maximize the encoding efficiency and the decoding efficiency of the moving picture by adaptively using several encoding types according to macro blocks of each color component of the current image. A prediction mode optimal for blocks of each color component for the current image is selected based on characteristics of a predetermined image(1410). A prediction image for the current image is generated according to the selected prediction mode(1417). If the similarity between the color components of the predetermined image is high, a prediction mode commonly applied to macro blocks of each color component is selected. If the similarity between the color components of the predetermined image is low, a prediction mode independently applied to macro blocks of each color component is selected.
