Good. In this way, the invention can be implemented by a general-purpose imaging device owned by the user.

  (5) The karaoke system 1 may include a communication terminal such as a mobile phone that can communicate with the set top box 10 as a part of the system. Specifically, the karaoke system 1 includes a communication terminal capable of data communication with the set top box 10 via a communication network, and the communication terminal uses, as a captured image, a part where the model of the karaoke apparatus 20 can be specified. The control unit 112 of the set-top box 10 includes an imaging unit capable of imaging, and acquires a captured image captured by the imaging unit of the communication terminal via a communication network such as the Internet. In this way, an apparatus that is often carried by a user, such as a mobile phone or a digital camera, can be used as the imaging means.

  (6) At the time of image recognition in the above-described model determination process (S310 to S320), it is determined that the image data of the karaoke apparatus 20 connected to the set top box 10 is not properly detected for the received image data. If it has been done, it may be notified to the user by displaying the fact on the display unit 50.

  In this way, for example, even when a new model of karaoke device is released, it is only necessary to update the server, and it is not necessary to distribute the information to all the set top boxes.

  (8) In addition, since a known image recognition method often takes a long time to be recognized in accordance with an increase in recognition accuracy, the following method may be used. That is, the processing from S310 to S330 in the above-described model determination processing (1) is not processed by the control unit 112 of the set-top box, but the image data that is output when S305 is executed is transmitted from the set-top box 10. The process from S310 to S330 is transmitted to the server 8 and performed by the control unit (not shown) of the server 8 capable of high-speed processing by the control unit 112 of the set-top box 10, and the result of the model verification is set as the set-top box. The control unit 112 may be notified, and the result may be used as an input in S350 to check the model in the system. In this way, collation can be performed in a shorter time than collation of models with the set top box 10 alone.

  (9) In the above embodiment, if all the image data do not match in S320 in the above-described model determination process (1) executed by the control unit 112 of the set top box 10 (S320: No), the process proceeds to S305. However, the present invention is not limited to this, and notifies the server 8 together with the image data that the image data has not all matched. The server 8 also receives the image data only when the error is received, and determines the model determination process ( The processing from S310 to S330 in 1) is performed by the control unit (not shown) of the server 8 capable of high-precision processing by the control unit 112 of the set-top box 10, and the model comparison result is displayed as the control unit of the set-top box 10. 112, and the result may be used as an input in S350 to check the model in the system. This reduces the possibility that image recognition cannot be performed and reduces the processing load of the server 8 because processing is performed by the server 8 only when the error occurs, as compared with the case where model comparison is performed using only the set-top box 10. You can also.

  (10) In the above embodiment, the karaoke system 1 includes the remote control terminal 15 capable of transmitting the first remote control signal to the set top box 10, and the set top box 10 receives the first remote control signal from the remote control terminal 15. Although it can receive by infrared communication, it is not restricted to this, You may make it provide the remote control terminal 550, such as an electronic quick sample which can mutually communicate data with the outside, instead of the remote control terminal 15.

[Description of model determination process (2)]
Below, the procedure of the model determination process (2) which the control part 112 with which the set top box 10 is provided performs is demonstrated based on the flowchart of FIG. This model determination process is executed when the set-top box 10 is activated for the first time, such as at the time of setting immediately after the set-top box 10 is installed in the karaoke box.

  First, it waits until it receives image data of a characteristic part of the karaoke apparatus 20 connected to the set top box 10 (in this embodiment, a front panel (not shown) of the chassis), which is captured by the camera 570 of the remote control terminal 550. When image data is received (S405), image recognition is performed on the received image data as follows (S310 to S320). Note that the image recognition process (S310 to S320) in the model determination process (2) is the same as the image recognition process (S310 to S320) in the model determination process (1) described above. The detailed explanation is omitted.

  As described above, when it is determined that the image data of the karaoke apparatus 20 connected to the set-top box 10 is properly detected as a result of performing image recognition on the received image data, the received image data Based on this, the model of the karaoke apparatus 20 is collated (S330). Specifically, the model name stored in the HDD 116 is referred to, and the model name associated with the image data that matches the received image is determined as the model of the karaoke apparatus 20. The model data of the model of the karaoke apparatus 20 determined in advance is read from the HDD 116, and the read model data is transmitted to the control unit of the remote control terminal 550 via the LAN 3 in the karaoke box, the wireless access point 509, and the wireless LAN communication unit 568. It transmits to 552 (S435). Then, by storing the read model data in the model data memory area 62 in the HDD 116, the setting content of the model of the remote control terminal 550 in the set-top box 10 is changed to the model of the karaoke apparatus 20 determined in advance ( S440).

  On the other hand, in remote control terminal 550, control unit 552 stores the received model data in memory 556, and changes the setting content of the model of remote control terminal 550 to the previously determined model of karaoke apparatus 20 (S445). Specifically, control unit 552 reads model data corresponding to the previously determined model of karaoke apparatus 20 from memory 556, and changes the models corresponding to display unit 558 and operation unit 560.

  Subsequently, for each type of function (for example, playback, stop, song number designation) in the previously determined model of the karaoke apparatus 20 (for example, model A), the type of the second remote control signal that instructs the operation of the function (For example, the remote control terminal control signal table (karaoke device model A) associated with each of the signals A1, A2, A3) is selected (S450). The above-mentioned remote control terminal control signal table refers to a table in which the keys of the operation unit 560 included in the remote control terminal 550 are associated with the instruction content, and is prepared for each model of the karaoke apparatus (see FIG. 5). In addition, after the model determination of the karaoke apparatus 20 by the model determination process (for example, model A), the function operation (for example, reproduction) is performed on the control unit 112 from the operation unit 560 of the remote control terminal 550 via the first remote control signal. When instructed, the control unit 112 refers to the remote control terminal control table (for example, model A) selected in the previous S450, and instructs the karaoke device 20 connected to the set top box 10 (for example, reproduction). A second remote control signal (for example, signal A1) corresponding to is transmitted to the karaoke apparatus 20. Therefore, the remote control terminal 550 can instruct the karaoke apparatus 20 to operate the function.

Then, this process ends.
