Abstract
A reproduction apparatuscollects sounds on which spread codes are superimposed with a microphoneto 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 apparatusin accordance with the intensity of the peaks of the calculated correlation values. A control portionidentifies content which is correlated with the identified content and is necessary for the reproduction apparatus. The control portionreads out the identified content data from a content data storage portionto output the musical score data and the audio data to a display portionand a reproduction portion, respectively. The display portiondisplays the input musical score data on a screen, while the reproduction portionreproduces the input audio data to generate sound signals.
