This configuration can achieve 5.1ch virtual reproduction with high sound quality in which sounds for 5.1 channels of LPCM 7.1ch audio information included in the contents are output as they are and sounds for the remaining 2 channels are reproduced artificially even if speakers compatible with the 5.1ch sound field system are connected.
