摘要： Provided is a multilayer picture encoding/decoding apparatus and method for reducing a dynamic range of residual pictures occurring in enhancement layers. The multilayer picture encoding method includes performing format down-conversion on an input picture, and generating a lower layer bitstream by encoding the format down-converted input picture; performing format up-conversion by adaptively or selectively applying a 1-dimensional (1-D) prediction filter to a picture of the lower layer depending on whether a lower layer prediction flag is set or not; and calculating a residual picture between the input picture and the format up-converted picture, and generating an enhancement bitstream by encoding the calculated residual picture.

摘要： A method, medium, and system encoding and/or decoding a moving picture. The moving picture encoding method may include selecting a prediction mode that is optimal for the macro blocks, which correspond to each other, of the color components of a current image based on the characteristics of a predetermined image, generating a predicted image for the current image according to the selected prediction mode, and encoding a moving picture using the predicted image. An optimal prediction mode can be adaptively applied to the macro blocks, which correspond to each other, of the color components, thereby increasing the moving picture's encoding and decoding efficiencies.
