PROBLEM TO BE SOLVED: To make a track division in audio data decoded from the multiplexed signal of the audio data having no track divisions and character information. SOLUTION: A signal received through an antenna 11 is supplied through a tuner circuit 12 and a demodulation error correction circuit 13 to a multiplexed data separation circuit 14. The multiplexed data separation circuit 14 separates the supplied signal into the packets of audio data and character information, and the audio data and the character information are supplied to a microcomputer 31. The microcomputer 31 makes a track division in the audio data having no track information based on the supplied audio data and character information. COPYRIGHT: (C)2004,JPO
