Abstract
A reproduction apparatus (2) collects sounds on which spread codes are superimposed with a microphone (20) to calculate correlation values between the collected sound signals and the same spread codes as those of an apparatus which performed the superimposition to identify content reproduced by a reproduction apparatus (1) in accordance with the intensity of the peaks of the calculated correlation values. A control portion (22) identifies content which is correlated with the identified content and is necessary for the reproduction apparatus (2). The control portion (22) reads out the identified content data from a content data storage portion (25) to output the musical score data and the audio data to a display portion (23) and a reproduction portion (26), respectively. The display portion (23) displays the input musical score data on a screen, while the reproduction portion (26) reproduces the input audio data to generate sound signals.
