However, even if the technique of Patent Document 1 is used, it is necessary for another user to enter the song ID and the team ID in association with each other instead of the representative. In addition, other users need to input the music ID while grasping which team they belong to. In other words, even if the technique of Patent Document 1 is used, the complexity of the team distribution work cannot be reduced.

Furthermore, since each user has a skill of singing karaoke (that is, the singing level is different for each user), depending on how the users are distributed, a team of users with a high singing level and a user with a low singing level may be used. There is a possibility that the team will be biased like the team of. If the team formation is biased in this way, the points will be different at the beginning of the team competition, and the content cannot be fully enjoyed.

An object of the present invention is to provide a karaoke device that allows users to easily enjoy contents such as team competition.

One invention for achieving the above object is a login processing unit for logging in a user to a karaoke device, an acquisition unit for acquiring singing score history of a plurality of logged-in users, and a plurality of acquired singing songs.

[Memory]
The storage unit 10a is a large-capacity storage device that stores various data, and is, for example, a hard disk drive. The storage unit 10a stores a plurality of song data for performing a karaoke performance by the karaoke device K.

The music data is provided with identification information (music ID) for identifying each karaoke music. The music data includes accompaniment data, reference data, and the like. The accompaniment data is MIDI format data that is the source of the karaoke performance sound. The reference data is data used as a reference when scoring a karaoke song by the user.

In the present embodiment, a part of the storage area of the storage unit 10a functions as the user information storage unit 11. The user information storage unit 11 stores user information. The user information is stored in association with the user identification information for identifying each user. The user identification information is information unique to each user, such as a user ID. The user identification information is set by the user himself when the karaoke device K is used for the first time, for example.

In the present embodiment, the user information includes a song scoring history. The song scoring history is a chronologically recorded scoring result obtained when a certain user sings a karaoke song of a certain song in the past, in association with the song ID of the certain song. The scoring result can be shown as a numerical value (scoring value) with 100 points as a perfect score.

The user information may include attribute information. The attribute information is various information associated with the user. As a specific example, the attribute information is sex, age, and birthplace.

[Communication part/input part]
Communication unit 10b provides an interface for communicating with remote control device 50. The input unit 10c is a configuration for the user to input various instructions. The input unit 10c is a button or the like provided on the karaoke body 10. Alternatively, the remote control device 50 may function as the input unit 10c.

It functions as the determination unit 500, the scoring unit 600, the calculation unit 700, and the display control unit 800.

(Login processing section)
The login processing unit 100 logs in the user to the karaoke device K.

For example, a case where the content of the team competition game provided by the karaoke apparatus K is used by six users (user U1 to user U6) will be described. Further, in the content of the team competition game according to the present embodiment, a plurality of users are divided into two teams and compete for the total points of each team. The content of the team competition is executed by, for example, selecting an icon displayed on the display screen of the remote controller 50.

After any one of the users selects the icon of the team competition game, the users U1 to U6 sequentially input their user IDs via the remote control device 50 of the karaoke device K. Based on the operation input from each user, the login processing unit 100 stores the user ID of each user in the storage unit 10a to complete the login of each user to the karaoke device K. Alternatively, each user may first complete login and perform a normal karaoke singing, and then the icon for the team competition may be selected.

(Acquisition department)
The acquisition unit 200 acquires the song scoring history of a plurality of logged-in users.

Specifically, the acquisition unit 200 acquires, from the user information storage unit 11, a song scoring history associated with the same user ID as the user ID of the logged-in user. When the users U1 to U6 described above log in, the acquisition unit 200 acquires the song scoring history of the users U1 to U6 from the user information storage unit 11. In this example, it is assumed that the user information storage unit 11 stores the song scoring history of the users U1 to U6 in advance.

(First determination unit)
The 1st determination part 300 determines the singing ability ranking of each user based on the acquired several song scoring history.

The singing ability ranking is a ranking of a plurality of users according to their skill in singing a karaoke song. The skill of the karaoke song can be determined, for example, based on the score result of the karaoke song.

The scoring result used to determine the singing order is not particularly limited as long as it is based on the singing scoring history. For example, it may be an average value of all the scoring results included in the song scoring history, or may be the highest score in a karaoke song performed during a certain predetermined period (eg, past one month).

In this embodiment, the 1st determination part 300 determines a singing ability ranking according to the highest score of the scoring result included in a predetermined period among the acquired singing history of the user U1-user U6. FIG. 3 is a diagram showing music pieces included in a predetermined period (music pieces sung by karaoke in a predetermined period) and their score values in the acquired song scoring history of the users U1 to U6.

Based on the song scoring history shown in FIG. 3, the 1st determination part 300 is "user U1 (99.5 points), user U2 (97.0 points), user U3 (91.0 points), User U4 (84.5 points), user U5 (84.0 points), user U6 (70.5 points)" is determined.

(Second determination unit)
The second determination unit 400 assigns each user to one of a plurality of teams and determines the singing order of each user based on the determined singing ability ranking.

The teams are distributed by associating a preset team ID with a user ID. Moreover, the teams are distributed so that the singing ability rankings are balanced among the teams.

For example, when allocating the users U1 to U6 to two teams (team A and team B), the second determination unit 400 alternately allocates each user in the descending order of singing ability (or in the descending order). ..

Specifically, when the singing ability ranking is determined in the order of "user U1, user U2, user U3, user U4, user U5, user U6", the second determination unit 400 The user U1 having the highest singing ability rank is assigned to the team A by associating the user ID of the user U1 with the team ID of the team A. Next, the second determination unit 400 associates the user ID of the user U2 having the second highest singing ability rank with the team ID of the team B, so that the user U2 is different from the user U1 in the team B. Sort into. On the other hand, for the user U3 having the third highest singing ability ranking, the second determining unit 400 assigns the team in consideration of the balance of the singing ability ranking. That is, the second determination unit 400 assigns the user U3 to the same team B as the user U2 by associating the user ID of the user U3 with the team ID of the team B. Similarly, the second determination unit 400 assigns the user U4 and the user U5 to the team A, and assigns the user U6 to the team B.

Moreover, the 2nd determination part 400 determines a user's singing order. The order of singing can be determined by various criteria.

For example, the second determination unit 400 determines the singing order so that a plurality of teams can perform karaoke singing in order (alternately in the case of two teams). In the above example, first, the second determination unit 400 determines the singing order for each team in ascending order of singing power rank. That is, in the team A, the singing order of the user U5, the user U4, and the user U1 is set, and in the team B, the singing power of the user U6, the user U3, and the user U2 is set. Next, the 2nd determination part 400 determines a song order so that team A and team B can sing a karaoke song alternately. For example, when singing a karaoke song from the team A first, the second determining unit 400 sings the user U5, the user U6, the user U4, the user U3, the user U1, and the user U2 in this order. Determine the order. It should be noted that which team starts the karaoke singing can be appropriately selected. Alternatively, the karaoke singing may be started in order from the team having the user with the lowest singing ability rank.

FIG. 4 is a diagram showing an example of two teams determined by the second determination unit 400. As shown in FIG. 4, the user U1, the user U4, and the user U5 are assigned to the team A, and the users U2, U3, and U6 are assigned to the team B. In addition, the singing order is the order in which the singing ability rank is low for each team. That is, the team A has the singing order of the user U5, the user U4, and the user U1, and the team B has the singing order of the user U6, the user U3, and the user U2. In the case of FIG. 4, one user will play a match three times. That is, the user U5 and the user U6 compete at the first time, the user U4 and the user U3 compete at the second time, and the user U1 and the user U2 compete at the third time.

On the other hand, if a user who is good at singing karaoke sings karaoke first, it may be difficult for a user who is not good at singing karaoke to sing. For example, when the singing order is determined as described above, the user U5 having a higher singing ability rank than the user U6 sings the karaoke song first, and thus the user U6 may have difficulty singing.

Then, the 2nd determination part 400 can also determine a singing order so that the singing order of a user with a low singing power rank may become early. In the above example, the singing order of user U6, user U5, user U4, user U3, user U2, and user U1 is determined.

(Third decision unit)
The 3rd determination part 500 determines the music which each user sings a karaoke song.

The 3rd determination part 500 determines the music which performs a karaoke singing about each user in which a team and a singing order were decided. The song to be sung by karaoke can be automatically determined by, for example, the third determination unit 500 selecting a song with the highest scoring result in the song scoring history for each user. Alternatively, each user himself/herself may select a piece of music desired to be sung by karaoke via the remote control device 50. The third determination unit 500 stores the determined music ID of the music in the storage unit 10a in association with the team ID and the user ID.

(Scoring department)
The scoring unit 600 scores each user's karaoke song.

A known method can be used to score the karaoke song. For example, it is assumed that the songs of all the users have been determined by the third determining unit 500. The karaoke device K reads the accompaniment data of the music piece Xn for which the first user sings a karaoke song from the storage unit 10a, and causes the speaker 20 to emit the karaoke performance sound. The user sings karaoke along with the karaoke performance.

When the user sings the karaoke song of the song Xn, the scoring unit 600 compares the singing voice signal based on the karaoke song of the user with the reference data of the song Xn, and obtains a scoring result according to the degree of coincidence. ..

In the present embodiment, the scoring unit 600 scores the karaoke song each time each user finishes the karaoke song, and obtains the score result. The scoring result is stored in the storage unit 10a in association with the user ID and the like.

(Calculator)
The calculation unit 700 calculates the score for each team by adding the scored result by the scoring unit 600 for each team each time the competition between one user belonging to each team is completed.

For example, as shown in FIG. 4, when all three battles are played, the calculation unit 700 calculates a score for each team each time one battle is completed.

Here, as a result of the first match, it is assumed that the scoring result of the user U5 is "70 points" and the scoring result of the user U6 is "80 points". In this case, the calculation unit 700 adds "70 points" to the score of the team A and "80 points" to the score of the team B based on the team ID linked to the user ID of each user. to add. In addition, the score before the first battle is started is “0 point” for both teams.

Next, as a result of the second match, it is assumed that the scoring result of the user U4 is "80 points" and the scoring result of the user U3 is "85 points". In this case, the calculation unit 700 adds “80 points” to the score of the team A to calculate the total score “150 points”. Further, the calculation unit 700 adds “85 points” to the score of the team B to calculate the total score “165 points”. The calculation unit 700 repeats the same processing until all the battles are completed.

(Display controller)
The display control unit 800 performs various display controls in the karaoke device K. The display control unit 800 according to the present embodiment causes the display device 30 to display the score for each team calculated by the calculation unit 700. The display control unit 800 causes the display device 30 to display the score each time the score for each team is calculated by the calculation unit 700, for example. In addition, the display control unit 800 causes the display device 30 to display the team distribution and singing order determined by the second determination unit 400.

==About processing in the karaoke device==
Next, a specific example of processing in the karaoke apparatus K according to this embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing a processing example in the karaoke apparatus K. In this example, it is assumed that the karaoke apparatus K is used by a plurality of users to execute the content of the team competition game. In addition, it is assumed that the singing score history of each user is stored in the user information storage unit 11 in advance.

The login processing unit 100 logs in each user to the karaoke device K according to the operation input from each user (login of each user, step 10).

The acquisition unit 200 acquires the song scoring history of the plurality of users who have logged in in step 10 (acquires the song scoring history of each user, step 11).

The 1st determination part 300 determines the singing ability ranking of each user based on the some singing scoring history acquired by step 11 (determination of singing ability ranking. Step 12).

The second determination unit 400 assigns each user to one of a plurality of teams and determines the singing order of each user based on the singing ability ranking determined in step 12 (determination of team and singing order). Step 13).

The 3rd determination part 500 determines the music which each user performs karaoke singing (the determination of music. Step 14).

After that, the karaoke apparatus K performs the karaoke performance of the music determined in step 14 based on the singing order determined in step 13 (start of karaoke performance, step 15).

The scoring unit 600 scores the karaoke song of the user each time the karaoke song of the user ends (scoring of the karaoke song. Step 16).

When the competition between one user belonging to each team is completed (Y in step 17), the calculation unit 700 adds the scoring results obtained in step 16 to each team, thereby The score is calculated (the score for each team is calculated, step 18).

The display control unit 800 causes the display device 30 to display the score for each team calculated in step 18 (displays the score for each team, step 19).

The karaoke device K repeats the processing of steps 15 to 19 until the singing of the karaoke songs by all the users is completed (until all the competitions are completed. In the case of Y in step 20).

As is clear from the above, the karaoke device K according to the present embodiment includes the login processing unit 100 that logs in the user to the karaoke device K, and the acquisition unit 200 that acquires the song scoring history of the plurality of logged-in users. , A first deciding unit 300 that decides the singing ability ranking of each user based on the acquired singing scoring history, and assigns each user to one of a plurality of teams based on the determined singing ability ranking. A second deciding unit 400 for allocating and deciding the singing order of each user, a third deciding unit 500 for deciding the music for which each user sings a karaoke song, and a score for scoring the karaoke song of each user It has a section 600 and a calculation section 700 that calculates a score for each team by adding the scored result by the scoring section 600 for each team every time the competition between one user belonging to each team ends. ..

According to such a karaoke device K, when the content such as a team battle is used, the user only logs in to the karaoke device K, and the teams are automatically distributed. Therefore, the user can easily perform a team competition. Moreover, since the teams are distributed based on the singing ability ranking of the user, the singing level of a certain team will not be extremely high (or low). Therefore, it is highly likely that the same scoring result will be obtained in each battle, and it is possible to compete in the battle until the end. That is, with the karaoke device K according to the present embodiment, it is possible to easily enjoy contents such as a team battle.

Moreover, the 2nd determination part 400 determines a singing order so that the singing order of a user with a low singing power rank may become early. By deciding the singing order in this manner, there is no possibility that a user with a high singing ability level will sing a karaoke song first, and it will be difficult for subsequent users to sing a karaoke song.

<Second Embodiment>
Next, a karaoke device according to the second embodiment will be described with reference to FIGS. 6 to 8. The configuration of the karaoke device K according to the present embodiment will be described in which, in accordance with the score of the previous battle, a song to be karaoke sung in the next battle is automatically determined. Detailed description of the same configuration as that of the first embodiment is omitted.

== Karaoke device ==
As shown in FIG. 6, in the present embodiment, the control unit 10d of the karaoke device K includes the login processing unit 100, the acquisition unit 200, the first determination unit 300, the second determination unit 400, and the third determination unit 500. , The scoring unit 600, the calculation unit 700, the display control unit 800, and the generation unit 900.

(Generator)
The generation unit 900 generates an expected score table in which correspondences between certain songs and expected scores are summarized for each user based on the song scoring history.

The expected score indicates an expected scoring result when a certain song is sung by karaoke.

The expected score can be determined based on the song scoring history. For example, it is assumed that the highest score of the music piece X1 is “99.5 points” in the song scoring history of the user U1. In this case, when the user U1 sings the song X1 in karaoke, "99.5 points" may be obtained as the highest point. Therefore, the generation unit 900 determines the expected score of the music piece X1 for the user U1 as “99.5 points”. In this way, the generation unit 900 can determine the highest score for each song recorded in the song scoring history as the expected score. Alternatively, the generation unit 900 may determine the average value for each song recorded in the song scoring history as the expected score. Further, the generation unit 900 may determine the expected score based on the entire song scoring history, or may determine the expected score based on only a predetermined period (for example, the latest one month) of the song scoring history. ..

The generation unit 900 generates an expected score table for the user U1 by associating the music ID and the expected score for the user U1. The generation unit 900 performs the same process for all users who participate in the team competition.

FIG. 7 shows the expected score table generated for the users U1 to U6 described in the first embodiment. According to FIG. 7, the expected score for the user U1 is in the range of 100 to 80 points. A music piece with an expected score of 100 points is a music piece X1, a music piece with an expected score of 95 points is a music piece X2, a music piece with an expected score of 90 points is a music piece X3, and a music piece with an expected score of 85 points is a music piece. The music piece having the expected score of 80 is the music piece X5.

In addition, in the example of FIG. 7, the expected score is in increments of 5, but it may be set in increments of 1 point, or conversely, in increments of 10. Further, when the expected score is set in increments of 5 as shown in FIG. 7, the actual scoring result may not match. In such a case, the generation unit 900 generates the expected score table by rounding the value of the scoring result. In the present embodiment, for example, the expected score “95 points” includes songs whose maximum score N is 92.5<N≦97.5, and the expected score “100 points” has the maximum score N. Rounding is performed so as to include a music piece having 97.5<N≦100. In this example, it is assumed that the score value obtained as a result of the user U1 singing the karaoke song of the music piece X3 is 92 points. In this case, the generation unit 900 generates an expected score table with the expected score of the music piece X3 as 90 points.

(Third decision unit)
The third determination unit 500 according to the present embodiment uses the difference between the scores of each team and the expected score table to minimize the difference between the scores of each team when one match is over. The users of each team decide the music to sing karaoke in the battle.

For example, it is assumed that the team A and the team B shown in FIG. 4 of the first embodiment perform a team battle. Further, it is assumed that the expected score table is determined as shown in FIG.

First, before the first match, the difference in score between teams is zero. Therefore, the 3rd determination part 500 selects the music with the same expected score about the user U5 and the user U6 who compete with each other for the first time, and determines as the music to which each user sings a karaoke song. In the example of FIG. 7, the expected scores of the user U5 and the user U6 overlap in the portion of 70 points to 65 points. In this case, the third determination unit 500 selects, for example, a piece of music with an expected score of “70 points”. That is, the third determination unit 500 refers to the expected score table, determines the song X24 having an expected score of 70 for the user U5, and determines the song X27 having an expected score of 70 for the user U6. .. That is, at this point, it can be expected that the difference between the scores of both teams will be minimized when the first match is over.

Next, it is assumed that after the singing of karaoke songs by the users U5 and U6 is completed, the calculation unit 700 calculates the score of the team A as "70 points" and the score of the team B as "80 points".

The third determination unit 500 calculates the difference between the score “70 points” of the team A and the score “80 points” of the team B. In this example, team B leads 10 points.

In this case, if the score of the team B is 10 points lower than the score of the team A in the next match, the difference between the scores of the teams becomes the minimum (0 point) at the end of the next match.

Therefore, regarding the users U3 and U4 who perform karaoke singing in the next competition, the third determination unit 500 is a piece of music that the user U4 belonging to the team A gets higher by 10 points (belongs to the team B). The user U3 who decides to do so will decide to lower the score by 10 points).

That is, the third determination unit 500 refers to the expected score table and determines the music piece X17 having the expected score of “80” for the user U4. On the other hand, the third determination unit 500 refers to the expected score table and determines the music X14 of "70 points" for the user U3 whose expected score is 10 points lower than the expected score "80" of the user U4. ..

In addition, the 3rd determination part 500 selects the music with the highest expected score about the said user among the music contained in an expected score table as a music which the user of the team with the lowest score for each team performs karaoke singing. It is preferable to determine. In the above example, it is preferable that the third determination unit 500 determines the music piece X16 (expected score “85 points”) having the highest expected score in the expected score table for the user U4. On the other hand, the third determination unit 500 determines the musical piece X13 of "75 points", the expected score of the user U3 is 10 points lower than the expected score "85 points" of the user U4.

When the difference is calculated, the value may not match the expected score in the expected score table. For example, the difference may be 3 points or 0.5 points with respect to the expected score table in steps of 5 as shown in FIG. In such a case, the third determination unit 500 determines the music by appropriately rounding the obtained difference so that the expected score of the expected score table can be referred to. For example, when the difference is 3 points, the third determination unit 500 sets the difference to “5 points” and determines the song in which the users of each team sing a karaoke song in the next competition.

==About processing in the karaoke device==
Next, a specific example of processing in the karaoke apparatus K according to this embodiment will be described with reference to FIG. FIG. 8 is a flowchart showing a processing example in the karaoke apparatus K. In this example, it is assumed that the karaoke device K is used by a plurality of users to execute the content of the team competition game. In addition, it is assumed that the singing score history of each user is stored in advance in the user information storage unit 11.

The login processing unit 100 logs in each user to the karaoke device K according to the operation input from each user (login of each user, step 20).

The acquisition unit 200 acquires the song scoring history of the plurality of users who have logged in in step 20 (acquires the song scoring history of each user, step 21).

The generation unit 900 generates an expected score table in which correspondences between certain songs and expected scores are summarized for each user based on the song scoring history acquired in step 21 (generation of expected score table, step 22. ).

Moreover, the 1st determination part 300 determines the singing ability ranking of each user based on the some singing scoring history acquired by step 21 (determination of singing ability ranking. Step 23). Note that step 22 and step 23 may be executed in reverse order or may be executed simultaneously.

The second determination unit 400 assigns each user to one of a plurality of teams based on the singing ability ranking determined in step 23, and determines the singing order of each user (determination of team and singing order). Step 24). The score for each team is 0 before the first match.

Next, the third determination unit 500, based on the difference in score between the teams and the expected score table generated in step 22, minimizes the difference in score between the teams at the end of this competition. The user of each team decides the song to sing a karaoke song in this battle (the song to sing a karaoke song in this battle is decided based on the difference in scores and the expected score table for each team. Step 25). As described above, the score difference between the teams is 0 before the first match. Therefore, the expected scores of the songs in which the users of each team sing a karaoke song in the first match are the same.

After that, the karaoke apparatus K performs the karaoke performance of the music determined in step 25 based on the singing order determined in step 24 (start of karaoke performance, step 26).

The scoring unit 600 scores the karaoke song of the user each time the karaoke song of the user is completed (scoring of the karaoke song. Step 27).

When the current match is over (Y in step 28), the calculation unit 700 updates the score for each team by adding the score result obtained in step 27 for each team (score for each team). Step 29).

The display control unit 800 causes the display device 30 to display the score for each team updated in step 29 (display the score for each team, step 30).

The karaoke apparatus K repeats the processing of steps 25 to 30 until all the battles are completed (Y in step 31).

As is clear from the above, the karaoke apparatus K according to the present embodiment associates a certain song with an expected score indicating a scoring result that can be expected when the certain song is sung karaoke based on the song scoring history. It has a generation unit 900 that generates an expected score table for each user. The third determination unit 500, based on the difference between the scores of each team and the expected score table before the start of the match, minimizes the difference between the scores of the team at the end of the match. , The user of each team decides the music to sing karaoke in the one match.

In this way, before the start of one match, the difference in score between teams is obtained, and when the match ends, the difference in score is minimized. By determining based on the score table, it is less likely that the total score for each team will deviate significantly. Therefore, the user can enjoy the content of the team competition game to the end.

In addition, the third determination unit 500 selects the song with the highest expected score for the user among the songs included in the expected score table as the song for which the user of the team with the lowest score for each team sings the karaoke song. You can decide. In this way, by singing the song with the highest expected score in karaoke, it is possible to enjoy a higher level match of karaoke songs.

<Other>
In the above embodiment, the case where there are two teams has been described as an example, but the same processing is possible even when there are three or more teams. Further, in the above embodiment, an example in which the user information is stored in the user information storage unit 11 has been described, but the karaoke device K does not necessarily have to store the user storage information. For example, the acquisition unit 200 may communicate with a server device (not shown) via the communication unit 10b to acquire the song scoring history for each user stored in the server device.

Also, the distribution of teams may be corrected according to the attribute information. For example, in the example of FIG. 4, among the team A, the user U1 is a woman, the users U4 and U5 are men, and the team B is that the user U2 is a man and the users U3 and U6. Is a woman. In such a case, it can be expected that a team of men and a team of women will be more exciting as a team competition. In such a case, it is preferable to correct the team allocation by exchanging the users U1 and U2. On the other hand, as a result of switching, the difference in singing level between teams may widen. Therefore, the allocation of teams can be corrected only when a predetermined condition is satisfied.

Specifically, the acquisition unit 200 acquires, from the user information storage unit 11, attribute information including any one of sex, age, and birthplace of the logged-in user.

When the predetermined condition is satisfied, the second determination unit 400 corrects the allocation of each team based on the acquired attribute information.

The predetermined condition is a standard for preventing the difference in singing level between teams from being too wide. If it can be determined that the singing levels of the users to be replaced are the same, there is no problem even if the team allocation is corrected. Therefore, for example, conditions such as users having consecutive singing ability ranks, that is, users competing with each other, or users having similar average scores of the scoring results included in the singing score history are predetermined. It can be set as a condition of. In addition, when the singing levels of all the users are antagonized (for example, when the highest point is included in the range of ±5 points), any user may be replaced.

Further, depending on the number of users, the number of users assigned to each team may not be the same. In such a case, the second determination unit 400 can determine and notify users who cannot be assigned to any team. For example, if there are users U1 to U5, they are divided into two teams. In this case, the second determination unit 400 determines and notifies one user. The decision of the user can be made according to various criteria. For example, the 2nd determination part 400 is a user who has a score difference with other users based on a singing scoring history (extremely good or extremely poor user), or a user with few singing scoring history. Can be determined. Alternatively, the second determination unit 400 may randomly determine from the logged-in users regardless of the song scoring history. The notification of the determined user is performed, for example, by displaying the name of the user who has not entered the team on the display device 30.

When there is a user who cannot be assigned to any team, the scoring unit 600 receives the evaluation of the karaoke singing of the user assigned to each team performed by the user, and based on the evaluation. It is possible to correct the score result of the user's karaoke song.

A known technique can be used for scoring evaluation by the audience (users who do not sing). For example, it is assumed that the user U5 is not assigned to any team in the above example. In this case, the user U5 operates the remote control device 50 to perform scoring evaluation (good, normal, bad) for the karaoke songs of the users U1 to U4. The scoring unit 600 corrects the scoring result according to the input. For example, the scoring unit 600 gives +5 points to the scoring result when “good” is selected, uses the scoring result as it is when “normal” is selected, and when “bad” is selected, Score -5 from the scoring results.

By being able to perform such scoring evaluation, users who have failed to participate in the team competition can enjoy it.

On the other hand, even when the number of users assigned to each team is not the same, if the singing levels of the teams are the same, the total score will not be greatly separated. Therefore, for example, when dividing the five users into two teams, the second determination unit 400 determines that the team with two singing power ranks is higher than the other team and the singing power rank is less than three. You may sort out.

Further, in the expected score table (see FIG. 7) in the above embodiment, an example is shown in which only one music piece is associated with one expected score for each user. On the other hand, a plurality of music pieces may be associated with one expected score. For example, when the generated expected score table includes the same music, the third determination unit 500 may determine the same music for different users. In such a case, karaoke singing of the same song is performed in a short period of time during a team competition, which may be boring depending on the user. Therefore, by preparing in advance an expected score table in which a plurality of songs are associated with one expected score, the third determination unit 500 determines the plurality of songs to be determined by then. It is possible to select a song that is not played (that is, a song that does not overlap with a song that another user sings karaoke).

The above embodiments are presented as examples and do not limit the scope of the invention. The above configurations can be appropriately combined and implemented, and various omissions, replacements, and changes can be made without departing from the scope of the invention. The above-described embodiments and modifications thereof are included in the scope of the invention and the scope of the invention, and are also included in the invention described in the claims and an equivalent range thereof.
