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.

Claims

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.

2. The method according to claim 1, further comprising:

a second retrieving step of retrieving audio or MIDI data based on the identified musical score; and

a reproducing step of reproducing the retrieved audio or MIDI data.

3. The method according to claim 1, wherein the first retrieving step retrieves the musical score data corresponding to the identified musical score from a reproduction apparatus or a server.

4. The method according to claim 1, wherein the inputting step collects the emitted sound with a microphone.

5. The method according to claim 1, wherein:

the superimposed identification information includes synchronization information,

the demodulating step further demodulates the synchronization information, and

the displaying step indicates a current reproduction timing on the musical score displayed on the display device based on the demodulated synchronization information.

6. A musical score device comprising:

a display device; and

a microprocessor configured to execute;

an inputting task that collects a sound that has been superimposed with content identification information and emitted from a speaker;

a demodulating task that demodulates the content identification information contained in the input sound signal;

an identifying task that identifies a musical score based on the demodulated identification information;

a first retrieving task that retrieves musical score data corresponding to the identified musical score; and

a display task that displays the identified musical score on the display device.

7. The musical score device according to claim 6, wherein the microprocessor is further configured to execute:

a second retrieving task that retrieves audio or MIDI data based on the identified musical score; and

a reproducing task that reproduces the retrieved audio or MIDI data.

8. The musical score device according to claim 6, wherein the first retrieving task retrieves the musical score data corresponding to the identified musical score from a reproduction apparatus or a server.

9. The musical score device according to claim 6, further comprising:

a microphone,

wherein the inputting task collects the emitted sound with the microphone.

10. The musical score device according to claim 6, wherein:

the superimposed identification information includes synchronization information,

the demodulating task further demodulates the synchronization information, and

the displaying task indicates a current reproduction timing on the musical score displayed on the display device based on the demodulated synchronization information.
