In addition, the storage unit 33 stores a program information transmission program 33a for distributing program information based on the above-described program information database 33b.

Next, the operation of the embodiment will be described.
(B) Operation First, when the user presses a power switch (not shown) of the operation unit 104 to supply power to the automatic performance device 1, the CPU 101 reads the basic OS from the ROM 102 and starts control of each unit. Next, when the user presses a switch (not shown) indicating the start of sound collection of the operation unit 104, the CPU 101 receives the press signal and enables the microphone 111 to collect sound.
The microphone 111 collects sound emitted from a radio receiver (not shown) and outputs an analog audio signal obtained by modulating the sound. The analog audio signal output from the microphone 111 is converted into a digital audio signal A (hereinafter referred to as DS-A) by the A / D converter 112.

At the same time, the CPU 101 enables the tuner 113 to receive and designates the frequency of the broadcast radio wave to be received to the tuner 113. The tuner 113 receives a broadcast radio wave of a designated frequency, demodulates the sound from the broadcast radio wave, digitizes it, and obtains a digital audio signal B (hereinafter DS-B).
The CPU 101 cuts out data strings for a predetermined time for each of the DS-A and DS-B acquired at the same time, records these data strings and the frequency F of the broadcast radio wave received by the tuner 113 in the RAM 103, and The time information t output from the timer 114 during the recording is recorded in the RAM 103.

Here, the data string of DS-A stored in the RAM 103 is a data string DA, and the data string of DS-B is a data string DB. In the present embodiment, values indicating the amplitude of the waveform for 2 seconds from the start of recording are recorded in order along the time flow in both the data string DA and the data string DB. Since the sampling frequency is 44100 Hz, the number of data in each data string is 88200. Here, the data string DA and the data string DB are
(DA (0), DB (0)) (DA (88199), DB (88199))
It expresses. Since the data string DA and the data string DB are recorded simultaneously under the control of the CPU 101, if the sound corresponding to both data is the same, the values indicating the amplitude of the waveform corresponding to the same elapsed time are set to each other. Are correlated. Therefore, the CPU 101 calculates the correlation coefficient R of the data string DA and the data string DB, and determines that the voices match when the obtained R is 0.9 or more. In this way, by using the correlation function R, it is determined that the two voices match even if they do not match completely. Thereby, for example, ambient noise is mixed in when the sound is picked up by the microphone 111, and DS-A and DS-B are matched even if the data string DA and the data string DB are not completely matched. Can be judged. The correlation coefficient R is expressed by the data string DA and the data string DB as follows:

  In the above determination, when the CPU 101 determines that the voices indicated by DS-A and DS-B do not match, the CPU 101 instructs the tuner 113 to switch the frequency of the received broadcast radio wave. When the frequency of the broadcast radio wave received by the tuner 113 is switched and reception is resumed, the above-described process is repeated to compare DS-A and DS-B at the new switched frequency. Since all receivable frequencies are stored in advance in the storage unit 105 or the ROM 102, the CPU 101 recognizes them, and if the data strings do not match even when compared with all these frequencies, the CPU 101 displays The section 122 is used to display that the program cannot be specified.

  On the other hand, when the CPU 101 determines that the voices indicated by DS-A and DS-B match each other, the CPU 101 transmits the frequency F of the broadcast radio wave and the time information t recorded in the RAM 103 via the communication unit 121. The device identification signal a-ID read from the ROM 102 is transmitted to the music server 2. The music server 2 extracts information indicating the installation region of the automatic performance device 1 from the registration information database 23b using the device identification signal a-ID received from the automatic performance device 1 as a key, and broadcasts from the installation region information and the frequency F. Is identified. When the music server 2 transmits the time information t to the program information server 3 belonging to the broadcast station, the program server 3 that has received the time information t searches the program information database 33b and transmits the transmitted time information. The music name broadcast in the broadcast time zone including t is returned to the music server 2.

The music server 2 that has received the music name from the program server 3 transmits the MIDI list related to the music from the MIDI list database 23c to the automatic performance device 1 together with the music name using the music name as a key.
When the automatic performance device 1 receives the song name and the MIDI list from the song server 2 via the communication unit 118, the automatic performance device 1 displays them on the display unit 122. When the user selects a URL indicating an arbitrary MIDI data download destination from the displayed music name and MIDI list via the operation unit 104, the CPU 101 sends information on the selected URL to the music server 2 via the communication unit 118. Send. The music server 2 transmits the MIDI data selected by the user to the automatic performance device 1 in accordance with the transmitted URL information, and the performance unit 123 of the automatic performance device 1 automatically performs the music based on the received MIDI data. . As described above, if the user likes the music broadcasted by the broadcasting station and wants to play it, the user can select from the music name or the MIDI list displayed on the display unit 122. You don't need to check the song title.

(1) In the above embodiment, the time lag between DS-A and DS-B is ignored, but an operation for correcting the time lag may be performed. For example, when it is known in advance that DS-A is 100/44100 seconds later than DS-B, the correlation coefficient may be calculated after shifting 100 data of the data string DA. In this case, for example, the DS-B data paired with the DS-A data DA (99) is the data DB (0). In addition, when such a delay time is not known in advance, a number of data shifts as described above may be tried and the correlation coefficient that is the most consistent may be determined.
Further, DS-A and DS-B are divided at predetermined time intervals (for example, 10 msec), fast Fourier transform is performed on each of the divisions, and feature data X-A indicating the characteristics of the voice waveform of DS-A and You may compare the feature data X-B which shows the characteristic of the audio | voice waveform of DS-B.

You may use for. Furthermore, by using such comparison of image information in combination with audio comparison, it is possible to improve the accuracy of broadcast station identification by audio comparison. The image information may be a moving image or a still image.

(5) In the above-described embodiment, the audio signals to be compared are digitized. However, analog waves may be compared without digitization. In this case, for example, an audio waveform obtained by sound collection and an audio waveform obtained by receiving a broadcast are input to a comparator, and when both outputs are within a predetermined range, the output time change is within a predetermined range. It may be determined that they match.

(6) Moreover, in the above-described embodiment, the frequency of the broadcast radio wave is used as a parameter to be transmitted to the music server 2, but the parameter to be transmitted to the music server 2 in order to specify the broadcasting station is not limited to the frequency. For example, it may be a channel number indicating a broadcast station set in advance in the broadcast receiving apparatus. Even in this case, the music server 2 only needs to be able to identify the broadcast station and the program information server 3 of the broadcast station from the combination of the channel number and the information indicating the installation area. In the information database 23b, a table showing the correspondence between channel numbers and broadcasting stations for each installation area may be stored, and the program information server 3 may be specified with reference to the table.
