摘要： A scalable lossless audio coding/decoding apparatus and method are provided. The scalable lossless audio coding apparatus includes a lossy coding unit which lossy codes an input audio signal and generates a lossy bitstream, a lossy signal regenerating unit which decodes the lossy bitstream, compares a decoded signal with the input audio signal, and regenerates a lossy signal that is lost when lossy coding is implemented, a lossless coding unit which lossless codes the lossy signal and generates the result of lossless coding as a lossless bitstream, and a multiplexing unit which multiplexes the lossy bitstream with the lossless bitstream and generates one output bitstream. The lossy-coded lossy bitstream is mixed with the lossless-coded lossless bitstream, thereby one output bitstream is generated and transmitted, and the lossy audio signal in which only the lossy bitstream is restored from the output bitstream or the lossless audio signal in which the lossy bitstream and the lossless bitstream are restored and mixed with each other can be selectively generated.
