Abstract: An system, method, and method of encoding/decoding a multi-channel audio signal, including a decoding level generation unit producing decoding-level information that helps a bitstream including a number of audio channel signals and space information to be decoded into a number of audio channel signals, wherein the space information includes information about magnitude differences and/or similarities between channels, and an audio decoder decoding the bitstream according to the decoding-level information. Accordingly, even a single input bitstream can be decoded into a suitable number of channels depending on the type of a speaker configuration used. Scalable channel decoding can be achieved by partially decoding an input bitstream. In the scalable channel decoding, a decoder may set decoding levels and outputs audio channel signals according to the decoding levels, thereby reducing decoding complexity.

Abstract: A pre-out terminal that outputs a left outside audio signal can be fixed and an increase of the number of DACs is prevented. In the case that a surround back left audio signal SBL and a left outside audio signal LW are included, the signal SBL is amplified and output to a surround back left SP terminal 14a through a switch S13a. The signal LW is amplified and output to a left outside SP terminal 14b through a switch S13c. The signal LW is supplied from a DAC 11b to a left outside pre-out terminal 11d through a switch S11c. At this point, in order to supply the signal LW to the left outside pre-out terminal 11d, a DAC 11c is not used, but the DAC 11b is used. Accordingly, the DAC 11c can be used for another signal (ex., ZONE2) to decrease the number of DACs.
