Abstract
A scalable encoding and decoding method and apparatus based on color information of moving pictures are provided. The color video encoding method comprises: generating an encoded luminance bitstream by encoding a luminance component using a motion prediction based encoding method; and generating at least one encoded chrominance bitstream by encoding at least one color format chrominance component using a motion vector generated by the motion prediction based encoding method. Using this method, storage, transmission, and reproduction of a moving picture can be efficiently performed by scalably encoding the moving picture according to a color format in which the moving picture is encoded.
