Abstract: 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.
