Audio data and additional audio information multiplexed therewith and distributed are received by an integrated receiver decoder. The received audio data is separated and decoded by a received-signal processing section. The data is then sent to an external recording unit and recorded onto a recording medium. The received additional audio information is separated by the received-signal processing section. The title of a musical piece and performer information are sent to the external recording unit through a digital interface or an infrared interface, and written onto a predetermined area of the recording medium.
