In order for the mobile phone to function as a remote control device of the karaoke device, it is necessary for the user to first set the reception standby state (Standby) by this function so that the communication link can be established.

The Bluetooth interface 10 of the karaoke apparatus transmits a connection request message (Inquiry) in the service area at a predetermined interval, and a mobile phone waiting in a reception standby state (standby) exists in the service area. I am searching for whether or not to do it. When a mobile phone in a standby state (standby) is brought into the service area, a communication link is established between the karaoke device and the Bluetooth interface (10, 25) of the mobile phone according to the Bluetooth protocol.

When the communication link is established, the karaoke apparatus operates on the mobile phone, and whether an application program (karaoke using program) for providing a performance reservation function for karaoke music exists in the memory of the mobile phone as a communication partner. Please use SDP (SDP
service Discovery Protocol
l) Inquire by a data packet called a request. The mobile phone that responds to this is the SD that stores and manages the registration information of its application program.
The contents of the P management table are described in the SDP response and returned to the karaoke device. Karaoke device receives SDP
It is checked whether or not the karaoke use program is registered in the response, and if it is present, a data packet containing a start instruction of the karaoke use program is transmitted to the mobile phone. Upon receiving this, the mobile phone immediately starts the karaoke use program.

On the other hand, if the karaoke use program is not registered, the karaoke device starts downloading the karaoke use program to the partner mobile phone. As soon as the karaoke use program is downloaded, the mobile phone starts the installation process of this program.

The karaoke utilizing program started on the mobile phone displays an appropriate performance reservation screen on the display unit of the mobile phone to accept the performance reservation operation. When the user operates the key operation unit to input the music ID checked from the table of contents or the like and performs a predetermined input completion operation, the microcomputer 21 causes the microcomputer 21 to store the terminal ID stored in the memory of the mobile phone and the input music. A data packet describing the ID is transmitted to the karaoke device via Bluetooth. The karaoke device associates the received terminal ID with the music ID, registers them in the performance reservation queue, and returns a data packet stating that the performance reservation of the music ID has been accepted to the mobile phone via Bluetooth. The mobile phone displays a message indicating that the reservation has been accepted on the display unit 34. In this way, the music ID reserved from the mobile phone is transferred to the music I reserved from the operation panel of the karaoke apparatus or the remote control transmitter.
It can be handled like D.

=== Confirmation of existence of reserved person === In the karaoke apparatus which manages the queue for performance reservation,
When the performance order of a certain music A approaches, it is confirmed whether the reservation person who reserved the music A is present. For example, when the performance of the music reserved for the music A before the music becomes one minute, the terminal I stored as a set with the music ID of the music A
The mobile phone with D is taken out and the mobile phone with that terminal ID is in the reception standby state (standby in the service area of the karaoke device.
Search by whether or not by). That is, as described above, the connection request message (Inquiry) is transmitted and the reception waiting state (standb) is set in the service area.
Search whether there is a mobile phone waiting in y),
Reception standby state (standb in the service area)
y) After establishing the communication link between the mobile phone and the Bluetooth interface, the terminal ID of the mobile phone
Inquires whether or not the terminal ID is the one requested.

Terminal I of the mobile phone which has established the communication link
If D matches the terminal ID requested by D, that is, the terminal ID of the mobile phone that reserved song A, it is determined that the reservation person is present and song A is played when the currently playing song ends.
Perform processing to start playing.

=== Change of playing order === In the above, when the mobile phone that reserved the music A is not found in the service area, the karaoke device reserves the music ID of the music A and the associated terminal ID. Change the queue from the beginning to the end. This is because it is useless for the absentee to play the reserved music, so the performance is postponed.

Here, a message may be displayed on the lower part of the screen of the display 8 of the karaoke apparatus to inform the person in the place that the performance order of the musical composition A is postponed. Furthermore, it may be possible for the person who sees the message display to cancel the change in the performance order. For example, as illustrated in FIG. 3, "N
"o" is displayed so that it can be selected and input, and if the person in the place wants to stop changing the performance order, select and input "No" on the operation panel of the karaoke machine, and the song will be played as originally planned. Be prepared to play A. By doing this, it is possible to deal with people who want to sing on behalf of the subscriber.

=== Other Embodiments === It is also possible to change the above-mentioned change in the performance order depending on the number of absences of the reservation person. That is, song A
Even if the reservation person is absent at the time when the performance order of is closed, it changes the song A to the end of the reservation queue for each time, for example, up to twice, but for the third absence Is removed from the queue, and so on. For this purpose, the karaoke apparatus is equipped with a counter (initial value 0) for counting the number of absences, and the value is incremented by 1 when the presence of the subscriber's mobile phone cannot be confirmed. Until the counter value reaches a predetermined value, for example, 3, music I of music A
This can be easily realized by performing the process of changing D to the end of the queue, and the process of deleting it from the queue when 3 is reached. Also in this case, it is convenient for the user to display the fact of deletion on the display 8 or the like of the karaoke apparatus, or to enable selection input to cancel the deletion.

At an appropriate time before the turn of a certain music A comes, for example, when the performance of the music three musics before the music A is started, the mobile phone that has reserved the music A displays "Remain until your reserved music. It is also possible to display a pre-notification message such as "3 songs". When displaying this via Bluetooth, the karaoke device establishes a communication link with the mobile phone that reserved the song A as described above at the time of advance notification, and says, "There are only 3 songs until your reserved song." It suffices to transmit a data packet that describes the content of "." The received mobile phone displays a message "There are 3 more songs up to your reserved song" on the display unit 34.

It is also possible to perform the same advance notice using electronic mail via the Internet network. In this case, the mobile phone needs to notify the e-mail address together with the terminal ID when making a performance reservation to the karaoke device. The karaoke device may create an e-mail with the content "You have up to 3 songs left to reserve" written in the body and send it to this e-mail address. By doing this, advance notice will be sent to those who have left the venue, which is very convenient because it is possible to return to the performance at a later time.

[0030]

According to the karaoke apparatus of the present invention, the personal portable information terminal that has reserved the music immediately before the karaoke apparatus plays the music is located nearby, that is, the person who reserved the music is on the spot. It is confirmed that the player is present and does not play if there is no person, so it is possible to avoid the situation where only karaoke performance is played, and it is possible to save useless time for people other than the reserved person. Even if the reservation person is absent, the reservation music does not disappear from the reservation list, and the opportunity to sing later comes around again, which is convenient for the reservation person who happens to be absent. If you can let us know in advance how long you will play the song you reserved, it will be possible to add urgent business such as shopping and ordering food and drink in the meantime. You can practice and prepare your mind. In addition, even if the reservation person is absent, it is possible to let someone in the place sing instead, so it may be an opportunity to unexpectedly sing a song with a tendency different from your usual one, so you will be present there Entertainment will be enhanced for all. As a result, the effect of increasing the number of people who use karaoke casually can be expected.
