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 residual picture is decoded first by demultiplexing an input enhancement layer bitstream into one or more bitstreams corresponding to an order of quality layers. Next, a residual picture is restored by independently decoding the bitstream for each quality layer. The restored residual picture is stored in a frame buffer. A finally restored residual picture is output by adding, to the restored residual picture, a picture that has undergone motion compensation in a reference frame within a same enhancement layer.
