(specific part)
The specifying unit 200 specifies a singer based on an instruction input from a user when group singing is selected when reserving one piece of music. Group singing is a method in which multiple users take turns singing karaoke songs. A singer is a user who performs group singing among logged-in users. At least two singers are identified.

A user who logs in to the karaoke system 1 reserves music via the remote controller 80 . For example, assume that user U1 selects music X1 via remote control device 80 .

At this time, the remote control device 80 displays an icon for reservation transfer and an icon for group song selection on the display screen.

When the user U1 selects the reserved transfer icon, the remote controller 80 transmits the music ID of the music X1 to the karaoke machine K. FIG. The karaoke machine K reserves the music piece X1 by registering the received music piece ID of the music piece X1 in the reservation queue.

On the other hand, if the user U1 selects the group singing selection icon before selecting the reserved transfer icon, the remote control device 80 transmits the music ID of the music piece X1 to the karaoke device K. At that time, the user IDs of all logged-in users and flag information indicating group singing are transmitted.

When the user ID and flag information are received, the identifying unit 200 identifies users U1 to U4 who are logged in to the karaoke system 1 as singers. The specifying unit 200 associates the user ID and flag information corresponding to each singer with the song ID of the song X1 and registers them in the reservation queue. The selection of the group song selection icon by the user U1 corresponds to "an instruction input from the user".

In the above example, we described an example in which all logged-in users are identified as singers, but it is also possible to identify only some of the logged-in users as singers. be.

For example, when the group singing selection icon is selected, the remote control device 80 causes the user name of the user currently logged in to the karaoke system 1 to be displayed on the display screen. User U1 selects at least two of the displayed users. In this case, when transmitting the music ID of the music piece X1 to the karaoke device K, the remote control device 80 transmits the user ID of the selected user and flag information indicating group singing.

When receiving the user ID and the flag information, the identifying unit 200 identifies the selected user among the users U1 to U4 who are logged in to the karaoke system 1 as the singer.

(acquisition part)
The acquisition unit 300 acquires the scoring history of the singer from the history storage unit.

When the identifying unit 200 identifies the singer, the obtaining unit 300 requests the server device S to transmit the identified singer's scoring history (that is, the singer's scoring history). The transmission request includes an instruction signal to transmit the ID of the singer (that is, the user ID) and the scoring history. When receiving the transmission request, the control means 30 of the server device S reads out the scoring history including the received user ID from the second storage unit 10b and transmits it to the karaoke device K. FIG. The acquisition unit 300 acquires the scoring history from the karaoke machine K and stores it in the storage unit 40a.

Note that the acquisition unit 300 may include the song ID of the selected song in the transmission request. In this case, the control means 30 reads only the scoring result corresponding to the song ID from the scoring history including the received user ID, and transmits it to the karaoke apparatus K as the scoring history.

(decision part)
Based on the obtained scoring history, the determining unit 400 selects a combination that allows each singer to sing karaoke in at least one singing section for one song, and in the combination, all of the one song. The combination with the highest total score value of the singing segment is determined. In addition, in this embodiment, the determining unit 400 determines a combination in which the number of times each singer sings is approximately equal.

A combination of a singer and a singing segment is determined based on preset criteria. For example, if the number of times each singer sings is equal, "(1) a combination of singing p singing sections per singer" and "(2) Out of the combinations of (1), one It is possible to set a criterion such as "combination with the highest total score value of all singing segments of a song". Note that, depending on the number of singers and the number of singing intervals, there is a possibility that the singing intervals may not be uniform (p may not be an integer). In this case, the reference for the number "p" of singing segments can be "(m/N)-1≤p≤(m/N)+1".

If the total number of singing sections of one song is "m" and the number of singers is "N", there are N ^m combinations of singers assigned to each singing section of one song. Moreover, when the number of times of singing is made equal, p=m/N.

As a specific example, it is assumed that the reserved song X1 is composed of eight singing sections S1 to S8. It is also assumed that users U1 to U4 are specified as singers. Furthermore, the criteria for determining the combination are "(1) a combination of singing p singing sections per singer (the number of singing times of each singer is approximately equal)", and "(2) (1) , the combination with the highest total score value for all singing segments of one song.

In this case, the determination unit 400 determines "2 times (2 sections)" as the number of times each singer sings (singing sections) from the total number of singing sections of the song X1 "8" and the number of singers "4". do.

Next, the determination unit 400 determines a score value for each singing section of the song X1 of each user based on the scoring histories of the users U1 to U4. FIG. 5 shows the scoring values determined by the determination unit 400 for each singer and each singing section.

Note that when there are multiple scoring results for one song for a certain user, the determination unit 400 can adopt the highest value for each singing segment as the scoring value for each singing segment. Alternatively, the determination unit 400 may employ the average score value for each singing segment as the scoring value for each singing segment.

Next, the determination unit 400 obtains the total score value of all the singing sections for all combinations (4 ⁸ =65536) when assigning a singer to each singing section in the song X1.

Then, the determination unit 400 identifies the combination with the highest total score value from among the combinations in which each singer sings twice in the 65536 combinations.

FIG. 6 is a diagram showing combinations of total values and singers (users) adopted as scoring values for each singing section. FIG. 6 shows them in descending order of the total value.

For example, in the case of the largest total value (782 points), the singers are only users U1 to U3. Therefore, it does not meet the above criteria.

On the other hand, in the case of the next largest total value (777 points), the lyrics are users U1 to U4. However, there is only one singing section for which the scoring value of user U1 is adopted. Therefore, it does not meet the above criteria.

In the case of the next highest total value (765 points), the singers are users U1 to U4. In addition, there are two singing segments for which each user's scoring value is adopted.

Therefore, the determining unit 400 adopts a combination with a total value of 765 points. That is, the determination unit 400 assigns the user U1 to the singing sections S1 and S5 of the song X1, the user U2 to the singing sections S2 and S6, and the user U3 to the singing sections S3 and S7. For the singing sections S4 and S8, the combination assigned by the user U4 is determined as the combination that satisfies the above criteria.

Each singer may be assigned to at least one singing section. That is, the determination unit 400 may determine a combination that allows each singer to sing karaoke in at least one singing segment.

Also, the combination determination processing by the determination unit 400 is an example. A combination that allows each singer to sing karaoke in at least one singing section of one song, and which has the highest total score value for all singing sections of one song. The process is not limited to the above process as long as it can be determined.

(presentation part)
The presenting unit 500 presents singers based on the determined combination for each singing section along with the karaoke performance of one piece of music.

The karaoke device K performs karaoke performances of songs in the order registered in the reservation queue. Here, when flag information is included in the reservation queue, the presenting unit 500 presents the singers based on the determined combination to the user who uses the karaoke device K for each singing section along with the karaoke performance. presented to Specifically, the presentation unit 500 presents the singers assigned to the certain singing section in the determined combination when the karaoke performance of a certain singing section is performed.

Singer presentation can be done in a variety of ways. For example, the presentation unit 500 can present the singer who should sing the singing segment during the karaoke performance by displaying the singer's name and avatar on the display device 60 . In addition, the presentation unit 500 may present not only the singer assigned to the singing section currently being performed in karaoke, but also the singer assigned to the singing section to be performed next in karaoke. In addition, there are various modes of presentation by singers. For example, as in Patent Literature 1, a singer may be indirectly presented by setting a different lyric character color for each singer in advance, and changing the color of the lyric character as the karaoke performance is performed. .

(Scoring section)
The scoring unit 600 scores each singing segment of karaoke singing of one piece of music, and presents the scoring results.

The scoring unit 600 scores each singing segment regardless of whether or not there is group singing. A known technique can be used as the scoring method. The presentation of the scoring results can be displayed as a total value on the display screen of the display device 60, for example. Alternatively, when group singing is selected, the scoring processing unit 600 may display the scoring result for each singing segment together with the name of the user who sang.
