For example, as described above, the music data D representing the music “music 02” is distributed from the distribution device 10 to the IP address “aaa.bbb.10.1”, and further “aaa.bbb.10.2”. Suppose that music data D representing the music “music 03” is distributed to the IP address “aaaa.bbb.10.3” and the IP address “aaa.bbb.10.3”. In this case, for example, if the communication unit 41 of the speaker device 40a extracts music data D representing the music “music 02” superimposed on the commercial power supplied from the PLC dedicated adapter 30, the communication unit 41 It is determined that the destination “aaa.bbb.10.1” of the music data D matches the IP address “aaa.bbb.10.1” of the own device, and the extracted music data D is supplied to the data buffer 42. On the other hand, if the communication unit 41 of the speaker device 40a extracts the music data D representing the music “music 03” superimposed on the commercial power supplied from the PLC dedicated adapter 30, the communication unit 41 It is determined that the destinations “aaa.bbb.10.2” and “aaa.bbb.10.3” of data D do not match the IP address “aaa.bbb.10.1” of the own device, and the extracted music data D is discarded without being supplied to the data buffer 42.
Similarly, when the communication unit 41 of the speaker devices 40 b and c extracts the music data D of “music 02” superimposed on the commercial power supplied from the PLC dedicated adapter 30, the extracted music data D is stored in the data buffer 42. Discard without supplying to. On the other hand, when the communication unit 41 of the speaker devices 40 b and c extracts the music data D representing the music “music 03” superimposed on the commercial power supplied from the PLC dedicated adapter 30, the extracted music data D is stored in the data buffer. 42. In this way, each speaker device 40 acquires the music data D distributed from the distribution device 10 to the own device.

  Subsequently, the speaker device 40 emits a music corresponding to the acquired music data D (step S120). More specifically, the music data D supplied to the data buffer 42 by the communication unit 41 is accumulated in a predetermined amount and supplied to the D / A conversion unit 43. The D / A converter 43 converts the music data D supplied from the data buffer 42 into an audio signal that is an analog signal, and the audio signal reproduction unit 44 receives the audio signal converted by the D / A converter 43. Amplify quantitatively. The speaker 45 generates a sound corresponding to the audio signal amplified by the audio signal reproducing unit 44. As a result, for example, the music “music 02” is emitted from the speaker device 40a, and the music “music 03” is emitted from the speakers 45 of the speaker devices 40b and 40c.

(Send music related information)
Subsequently, an operation in which the related information transmitting device 20 transmits music related information to the lighting device 50 will be described.
When the speaker device 40 emits a song in step S120, the speaker device 40 transmits a song ID for identifying the emitted song and its own identification information from the communication unit 41 to the related information transmitting device 20 (step S130).

If both IP addresses do not match, the receiving unit 51 sends the extracted music related information to the modulation unit. Discard without supplying to 52.

  For example, as described above, the distribution apparatus 10 transmits “music 02 introduction information” and “discount ticket” to the IP address “aaa.bbb.10.11”, and “aaa.bbb.10.12”. Suppose that “music 03 introduction information” is transmitted to the IP address “aaa.bbb.10.13”. In this case, for example, if the receiving unit 51 of the lighting device 50a extracts “music 02 introduction information” and “discount ticket” superimposed on the commercial power supplied from the PLC dedicated adapter 30, the receiving unit 51 , The destination “aaa.bbb.10.11” and the IP address “aaa.bbb.10.11” of the own device are determined to match, and the extracted “music 02 introduction information” and “discount ticket” are modulated. To the unit 52. On the other hand, if the receiving unit 51 of the lighting device 50a extracts “music 03 introduction information” superimposed on the commercial power supplied from the PLC dedicated adapter 30, the receiving unit 51 receives the destination “aaa.bbb. 10.2 ”,“ aaa.bbb.10.13 ”and the IP address“ aaa.bbb.10.11 ”of the own device are determined not to match, and the extracted“ music 03 introduction information ”is modulated by the modulation unit 52. Discard without supplying to. Similarly, when the receiving unit 51 of the lighting devices 50 b and c extracts “music 02 introduction information” and “discount ticket” superimposed on the commercial power supplied from the PLC dedicated adapter 30, the extracted information is obtained. Discard without supplying to the modulator 52. On the other hand, the receiving unit 51 of the lighting devices 50 b and c extracts “music 03 introduction information” superimposed on the commercial power supplied from the PLC dedicated adapter 30, and supplies the extracted information to the modulation unit 52. Thus, each lighting device 50 receives the music related information distributed from the related information transmitting device 20 to the own device.

  And the illuminating device 50 carries on the light irradiated from the light source 54 the signal showing the received music related information, and transmits (step S170). More specifically, the modulation unit 52 of the illumination device 50 superimposes a signal representing music-related information supplied from the reception unit 51 on a signal supplied to the light source 54 and supplies the signal to the light source control unit 53. The light source control unit 53 causes the light source 54 to emit light according to the signal supplied from the modulation unit 52, and the light source 54 emits light according to the control of the light source control unit 53. In this way, for example, the lighting device 50a emits light superimposed with signals representing “music 02 introduction information” and “discount coupon” transmitted from the related information transmitting device 20, and from the lighting devices 50b and 50c.

A signal representing “02 introduction information” and “discount coupon” is extracted.

  When the light emitted from the illumination device 50 is received and a signal on which the light is superimposed is extracted, the control unit 61 of the receiving terminal 60 displays the music related information represented by the extracted signal on the display unit 65 (step S <b> 1). S190). In this example, “music 02 introduction information” and “discount ticket”, which are music related information of the music “music 02”, are displayed on the display unit 65 of the receiving terminal 60. Thus, the user can obtain “music 02 introduction information” and “discount ticket”, which are information related to the music “music 02” emitted from the speaker device 40a.

  Further, for example, a user who has the receiving terminal 60 is listening to a song “music 03” emitted from the speaker device 40b in the vicinity of the speaker device 40b shown in FIG. In order to obtain music related information related to the music “03”, it is assumed that the light receiving unit 63 of the receiving terminal 60 is directed to the light irradiated from the lighting device 50b by moving into the irradiation range Sb of the lighting device 50b. In that case, the light receiving unit 63 of the receiving terminal 60 receives the light emitted from the lighting device 50b and supplies the light to the demodulating unit 64. The demodulating unit 64 superimposes the “music” superimposed on the light supplied from the light receiving unit 63. A signal representing “03 introduction information” is extracted. Then, the control unit 61 causes the display unit 65 to display “music 03 introduction information” represented by the extracted signal. Thus, the user can obtain “music 03 introduction information” that is information related to the music “music 03” emitted from the speaker device 40b.
