<Embodiment>
With reference to FIGS. 1-6, the karaoke system 1 which concerns on embodiment is demonstrated.

== Karaoke system ==
As shown in FIG. 1, the karaoke system 1 includes a plurality of karaoke devices (karaoke devices K1 to Karaoke devices Kn) and a server device S. Each karaoke apparatus and server apparatus S can communicate with each other via a network N. The network N is a transmission line such as a public telephone line network or an Internet line. The karaoke system 1 according to the present embodiment is an example of a “recommendation system”.

== Server device ==
The server device S is a computer that manages various types of information related to the karaoke device and processes information transmitted from the karaoke device. FIG. 2 is a diagram illustrating a hardware configuration example of the server apparatus S. The server device S includes a storage unit 10, a communication unit 20, and a control unit 30. Each component is connected to the bus B via an interface (not shown).

[Storage unit]
The storage unit 10 is a large-capacity storage device that stores various data. The storage unit 10 according to the present embodiment includes a data storage unit 10a.

(Data storage unit)
The data storage unit 10a stores high score singing data. The high-scoring song data includes identification information (music ID) indicating a song corresponding to the karaoke song for which a scoring result of a predetermined value or more is obtained, and identification information (user ID) indicating a user who performed the karaoke song. Are associated with each other. The scoring result equal to or higher than a predetermined value refers to a result indicating a value higher than a certain standard (for example, 90 or more points out of 100) among scoring results of karaoke singing. The high score singing data is generated by each karaoke device and transmitted from each karaoke device to the server device S. Specific processing relating to the generation of high score singing data will be described later.

  FIG. 3 shows an example of the high score song data stored in the data storage unit 10a. As is clear from FIG. 3, a plurality of music IDs may be associated with one user ID. For example, at least two music IDs are associated with the user ID “XXXX”. This is because when the user corresponding to the user ID “XXXX” sings a song corresponding to the song ID “AAAAA-01” and the song ID “BBBB-05”, the scoring result is a predetermined value or more. It shows that there was. Alternatively, one music ID may be associated with a plurality of user IDs. For example, the music ID “AAAAA-01” is associated with at least three user IDs. This indicates that when each user corresponding to each user ID sang a song corresponding to the song ID “AAAA-01”, the scoring results were all equal to or greater than a predetermined value. .

  Note that the data storage unit 10a may store, as high-score singing data, information obtained by associating actual scoring results with music identification information and user identification information.

[Communication Department]
The communication unit 20 provides an interface for connecting the server device S and each karaoke device.

[Control unit]
The control unit 30 performs various controls in the server device S. The control unit 30 includes a CPU and a memory (both not shown). The CPU realizes various functions by executing programs stored in the memory. In the present embodiment, when the CPU executes a program stored in the memory, the control unit 30 functions as a search unit 30a, an extraction unit 30b, and an information transmission unit 30c.

(Search part)
When the high score music data obtained by singing a certain karaoke song to a certain user is received from the karaoke device, the search unit 30a refers to the data storage unit 10a and is associated with the identification information of the certain tune. Search for identification information of other users.

  Other users are users other than the user (a user) who performed the karaoke singing that is the basis of the received high-score singing data. The high score song data of other users is stored in the data storage unit 10a. That is, other users perform karaoke singing before a certain user sings karaoke. Moreover, the karaoke song has a scoring result of a predetermined value or more.

  For example, an example will be described in which the high-score singing data obtained by the user X singing the song A with karaoke is received from the karaoke apparatus K1.

  In this case, the search unit 30a refers to the data storage unit 10a and searches whether there is identification information of another user associated with the identification information of the music piece A.

  When there is identification information of another user associated with the identification information of the music piece A, the search unit 30a outputs the identification information of the other user to the extraction unit 30b. There may be at least one other user identification information.

  On the other hand, when there is no other user identification information associated with the identification information of the music A, the search unit 30a notifies the karaoke apparatus K1 that has transmitted the high-scoring song data that there is no recommended music. . The “recommended music” is music suitable for recommending a karaoke song to a user of the karaoke apparatus (in this example, a user X of the karaoke apparatus K1).

  In addition, the search part 30a may search whether the received high score song data is memorize | stored in the data storage part 10a, and when it is not memorize | stored, you may add the said high score song data to the data memory part 10a. .

  For example, in the above example, the search unit 30a searches whether the high score singing data in which the user ID of the user X and the song ID of the song A are associated is stored in the data storage unit 10a. When the high score singing data is not stored, the search unit 30a stores the high score data in the data storage unit 10a. Thereafter, the search unit 30a searches whether there is identification information of another user associated with the identification information of the music piece A. On the other hand, when the high-scoring song data is stored, the search unit 30a does not perform any special processing and continues to search whether there is identification information of other users associated with the identification information of the music piece A. .

(Extractor)
When there is identification information of another user associated with the identification information of a certain music piece, the extraction unit 30b uses a certain usage based on the identification information of the other music piece associated with the identification information of the other user. The identification information of the recommended music for the person is extracted.

  Other music is music other than a certain music among music indicated by identification information associated with identification information of other users. Other music may include music that a certain user has sung karaoke in the past.

  For example, in the above example, it is assumed that the search unit 30a has obtained a search result that there is a user ID of another user associated with the music ID of the music A. In this case, the search unit 30a outputs the user IDs of other users to the extraction unit 30b.

  The extraction unit 30b refers to the data storage unit 10a, and extracts the song IDs of the songs other than the song A among the song IDs of the songs associated with the user IDs of other users. The music corresponding to the extracted music ID corresponds to the recommended music. The extraction unit 30b outputs the extracted music ID to the information transmission unit 30c.

  Here, all the extracted music IDs may be the music IDs of the recommended music. Further, the music ID of the recommended music may be a predetermined number (for example, 10 music IDs) set in advance among the plurality of extracted music IDs. At this time, when the extracted music IDs are less than the predetermined number, all the extracted music IDs may be used as the music IDs of the recommended music.

  Alternatively, the extraction unit 30b may count the same music pieces among other music pieces, and may use a predetermined number of music pieces as recommended music pieces in descending order.

  For example, suppose that there are 9 songs B1, 15 songs B2, 3 songs B3, 8 songs B4, and 1 song B5 to B20 as song IDs of other songs. In this case, the extraction unit 30b counts the same music IDs among the music B1 to the music B20, and the number of the music IDs is in descending order (that is, music B2, music B1, music B4, music B3, music B5 to music B20). In order), a predetermined number (for example, the top 4 songs) of songs can be set as recommended songs, and the song IDs of the recommended songs can be extracted.

  Moreover, when the actual scoring result is linked | related with each high scoring song data, the extraction part 30b is good also considering a predetermined number of music as a recommendation music in order with a high scoring result among other music.

(Information transmitter)
The information transmission part 30c transmits the identification information of the extracted recommended music with respect to the karaoke apparatus with which a certain user performed karaoke singing.

  For example, it is assumed that the extraction unit 30b has extracted the music ID of the recommended music for the user X who uses the karaoke apparatus K1. In this case, the information transmission unit 30c transmits the song ID of the recommended music extracted in association with the user ID of the user X to the karaoke apparatus K1 where the user X performed the karaoke song.

  Then, the user X uses the remote control device 80 to select himself / herself from a plurality of logged-in users, and uses the search function to select the song A to make a reservation for karaoke singing. Thereafter, the user X performs karaoke singing of the music piece A. The calculation unit 100 calculates a scoring result when the user X performs the karaoke singing of the music piece A based on the singing voice signal of the user X input from the microphone 70.

(Judgment part)
The determination unit 200 determines whether the scoring result is a predetermined value or more.

  The predetermined value is a threshold value for extracting a high scoring result from a plurality of scoring results, and is generally a value considered to be a high scoring (for example, 90 points out of 100, the rank of the scoring results) Is A rank).

  The determination unit 200 determines whether the scoring result output from the calculation unit 100 is greater than or equal to a predetermined value. When it determines with a scoring result being more than predetermined value, the determination part 200 will identify the music corresponding to the karaoke song used as the origin of the scoring result, and the identification information which shows the user who performed the karaoke song Is output to the data transmission unit 300.

  For example, in the above example, it is assumed that the scoring value “92 points” when the user X performs the karaoke singing of the music piece A is output from the calculation unit 100. Further, it is assumed that “90 points” is set as the predetermined value. In this case, the determination unit 200 compares the scoring value “92 points” with the predetermined value “90 points” and determines that the scoring result is equal to or greater than the predetermined value. Then, the determination unit 200 outputs the music ID indicating the music A and the user ID indicating the user X to the data transmission unit 300.

(Data transmission part)
The data transmission unit 300 stores high-scoring song data in which identification information indicating a song corresponding to a karaoke song for which a scoring result equal to or greater than a predetermined value is obtained and identification information indicating a user who performed the karaoke song are associated with each other. To device S.

  For example, it is assumed that the music ID indicating the music A and the user ID indicating the user X are output from the determination unit 200. In this case, the data transmission unit 300 associates the music ID indicating the music A with the user ID indicating the user X, and transmits it to the server device S as high-scoring song data.

(Display control unit)
The display control unit 400 performs various display controls in the karaoke apparatus K1. In the present embodiment, the display control unit 400 displays the recommended music on the display unit based on the identification information of the recommended music received from the server device S. The display device 60 and the remote control device 80 according to the present embodiment are examples of a “display unit”.

  For example, in the server device S, the extraction unit 30b extracts the song ID of the recommended song for the user X, and the information transmission unit 30c transmits the identification information to the karaoke device K1 where the user X performed karaoke singing. To do.

  In this case, the display control unit 400 displays the recommended music for the user X based on the received music ID of the recommended music. For example, the display control unit 400 displays the song name corresponding to the song ID of the recommended song and the song ID itself on the display screen of the remote control device 80. The music name of the recommended music can be specified by referring to the attribute information stored in the storage unit 43 based on the music ID of the recommended music.

  There are various timings for displaying recommended music. For example, the display control unit 400 may display the recommended music on the display screen of the display device 60 immediately after the end of the karaoke performance of the music whose scoring value is greater than or equal to a predetermined value. In addition, the display control unit 400 transfers the music ID of the recommended music received from the server device S to the remote control device 80. The display control unit 400 may display recommended music on the display screen of the remote control device 80 at a timing when a certain user selects music.

  Note that music recommended for a certain user may include music that the user has sung in the past. Therefore, the display control unit 400 refers to the singing history for each user managed by the remote control device 80, and displays the singing history included in the recommended singing song except for the singing included in the singing history of a certain user. It is also possible.

== About processing in karaoke system ==
Next, a specific example of processing in the karaoke system 1 according to the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating a processing example in the karaoke system 1. In this example, an example in which the user X performs karaoke singing of the music piece A by the karaoke apparatus K1 will be described. In addition, it is assumed that a plurality of high score singing data is stored in advance in the data storage unit 10a of the server device S.

  User X makes a reservation for song A via remote controller 80 of karaoke device K1 (reservation of song A. Step 10). The karaoke apparatus K1 performs a karaoke performance of the music piece A. User X performs karaoke singing along with the karaoke performance of music A (karaoke singing, step 11).

  The calculation unit 100 calculates a scoring result based on the karaoke song of the user X in Step 11 (calculation of the scoring result. Step 12). The determination unit 200 determines whether or not the scoring result calculated in step 12 is equal to or greater than a predetermined value (scoring result determination, step 13). In this example, it is assumed that the scoring result calculated in step 12 is greater than or equal to a predetermined value.

  Based on the determination result of step 13, the data transmission unit 300 associates the music ID indicating the music A corresponding to the karaoke song in step 11 and the user ID indicating the user X who performed the karaoke song. The score singing data is transmitted to the server device S (transmission of high score singing data. Step 14).

  When the search unit 30a receives the high-scoring song data transmitted in step 14, the search unit 30a refers to the data storage unit 10a and determines whether there is a user ID of another user associated with the song ID of the song A. Search (search for another user ID, step 15). In this example, it is assumed that user IDs of other users are obtained as a result of the search.

  The extraction unit 30b extracts the song ID of the recommended song for the user X based on the song ID of the other song associated with the user ID of the other user searched in step 15 (recommended song of the recommended song). Extraction, step 16).

  The information transmitting unit 30c transmits the music ID of the recommended music extracted in step 16 to the karaoke apparatus K1 where the user X performed the karaoke song (transmits the music ID of the recommended music, step 17).

  The display control unit 400 of the karaoke apparatus K1 displays the recommended music on the display screen of the remote control device 80, for example, based on the music ID of the recommended music transmitted in step 17 (recommended music display; step 18).

  As described above, the server device S according to the present embodiment includes identification information indicating the music corresponding to the karaoke song for which a scoring result equal to or greater than the predetermined value is obtained, and identification information indicating the user who performed the karaoke song. When the data storage unit 10a that stores the associated high-score singing data and, for example, the high-score singing data obtained when the user X sings the song A from the karaoke device K1 is received from the karaoke apparatus K1, the data storage unit 10a is stored. When there is a search unit 30a for searching whether or not there is identification information of another user associated with the identification information of the music A, and identification information of another user associated with the identification information of the music A The extraction unit 30b for extracting identification information of recommended music for the user X based on the identification information of other music associated with the identification information of the other user; Recommend the identification information of the music, having an information transmitting section 30c to be transmitted to the karaoke apparatus K1 that user X makes a karaoke singing.

  It can be considered that users who have obtained a scoring result equal to or higher than a predetermined value for the same music A have similar tendencies for music that can be sung well. Therefore, for example, even if the user X has never performed karaoke singing so far, other users who have similar tendencies of singing karaoke can obtain a scoring result above a predetermined value. If so, there is a high possibility that the user X can aim for a high score. The server apparatus S can extract such music as recommended music and provide it to the karaoke apparatus in which the user X performs karaoke singing. In other words, according to the server device S according to the present embodiment, it is possible to recommend music pieces that are highly likely to have high scoring results to the user.

  Moreover, the search part 30a can search whether the received high score song data is memorize | stored in the data storage part 10a, and when it is not memorize | stored, the said high score song data can be added to the data memory part 10a. . Thus, when new high score song data is received, the variation of recommended music can be increased by adding it to the data storage unit 10a.

  Moreover, the extraction part 30b can count the same music among other music, and can make a predetermined number of music into a recommendation music in order with the number. By counting the same music from among a plurality of other music and setting only a part of the music having a large number as the recommended music, the user can easily select music when performing karaoke singing. In addition, among other music pieces, there are music pieces in which only one user has obtained a high score, and there are music pieces in which a plurality of users have obtained a high score. In this case, it can be said that the music from which a plurality of users obtained a high score is a music that tends to aim for a higher score. That is, according to such a server device S, it is possible to recommend a song with a higher possibility of aiming a high score to the user.

  Furthermore, the karaoke system 1 (recommendation system) according to the present embodiment includes a plurality of karaoke devices and a server device S that can communicate with each karaoke device. The karaoke apparatus includes a calculation unit 100 that calculates a scoring result based on a user's karaoke song, a determination unit 200 that determines whether or not the scoring result is a predetermined value or more, and a karaoke that has a scoring result that is a predetermined value or more. The data transmission part 300 which transmits the high score song data which linked | related the identification information which shows the music corresponding to a song, and the identification information which shows the user who performed the said karaoke song to the server apparatus S. When the server device S receives from the karaoke device K1 the data storage unit 10a that stores the received high score singing data and the high score singing data obtained by the user X singing the tune A, the data storage is performed. The search unit 30a, which searches for whether there is identification information of another user associated with the identification information of the song A with reference to the unit 10a, and identification information of the other user associated with the identification information of the song A If there is, the extraction unit 30b that extracts identification information of recommended music for the user X based on the identification information of other music associated with the identification information of the other user, and the extracted recommended music And an information transmission unit 30c that transmits the identification information to the karaoke apparatus K1 on which the user X performed karaoke singing. Further, the karaoke apparatus K1 includes a display control unit 400 that displays the recommended music on the remote control device 80 or the like based on the received identification information of the recommended music.

  As described above, the server device S provides the extracted recommended music to the karaoke device in which the user X performs karaoke singing. The karaoke device can visually present the recommended music provided from the server device S to the user X. That is, according to the karaoke system 1 according to the present embodiment, it is possible to recommend a song with a high possibility that the scoring result will be a high score to the user.

  Moreover, the display control part 400 can be displayed except the music contained in a user's song history among the music contained in a recommendation music. In this way, by removing music that the user has sung in the past from the recommended music, the user can increase the repertoire of music that is highly likely to be scored high.
