Musical score device that identifies and displays a musical score from emitted sound and a method thereof
First Claim
1. A method of displaying a musical score, the method comprising:
- an inputting step of inputting a sound signal by collecting a sound that has been superimposed with content identification information and emitted from a speaker;
a demodulating step of demodulating the content identification information contained in the input sound signal;
an identifying step of identifying a musical score based on the demodulated identification information;
a first retrieving step of retrieving musical score data corresponding to the identified musical score; and
a display step of displaying the identified musical score on a display device.

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.
