Abstract
A multilayer video encoding/decoding apparatus and method using residual videos, in which a base layer video is output by decoding a base layer bitstream, individual layer videos are output by decoding encoded individual layer bitstreams, format up-conversion is performed on the base layer video and at least one of the individual layer residual videos, and individual layer videos having different formats from the base layer video are reconstructed using the conversion results.
