In the present embodiment, transmission of user information from the host 5 to the commander 2 or the remote control device 1 is performed on the assumption that information for specifying a communication partner such as an IP address of each device is stored in advance. As another transmission method, if the remote control device 1 and the commander 2 have a well-known “binding” or “correlation” relationship in karaoke, the host 5 once transmits user information to the logged-in remote control device 1. Then, as necessary from the logged-in remote control device 1 (for example, when a song reservation instruction is given from the remote control device 1 to the commander 2,
It may be retransmitted to the commander 2 of the binding partner (along with the music reservation information), or may be received once by the commander 2 and retransmitted from the commander 2 to the remote control device 1.

On the commander 2 side that has received the user information (S103), various service processes such as a music selection process and a performance process are provided based on the received user information (S104). When logout is requested by the user (S105), the service process is interrupted, and various histories (logs) during the service process or user information reflecting the setting change by the user is transmitted to the karaoke host 5 (S106). Here, as the user information, not only all the information but also the updated difference may be transmitted. The karaoke host 5 updates the database stored in the storage unit 1 based on the received user information (S124).

  The flow from one user authentication process (login) to logout has been described above, but the commander 2 and the remote control device 1 of this embodiment are in a state where a plurality of authenticated users (authenticated users) are logged in at the same time. By using the user interface described with reference to FIG. 2, it is possible to switch and use a user who provides a service (hereinafter referred to as “active user”).

  FIG. 5 is a diagram showing an active user top screen according to the embodiment of the present invention. As shown in this figure, when a plurality of people are logged in, the logged-in user column 103 displays the logged-in images 103a to 103e (face portions in this embodiment) of the logged-in user. In the login user column 103, the user whose background is highlighted at the right end is the active user 103e. In the state shown in the figure, the service for the active user 103e, that is, the user information of the active user 103e is used. The service is running.

  On this active user top screen, by selecting “Search for a song”, a search based on a singer name and a song name can be performed as in the case of a conventional song book. When “My Room” is selected, a music search specialized for the active user can be performed using the My Uta table in the user information.

  FIG. 6 shows a My Room screen that is a screen when “My Room” is selected on the active user top screen. On this My Room screen, as shown in the figure, operation buttons such as My Uta 104, My Artist 105, and Rireki 106 are displayed. By selecting these, various music selection methods using user information are selected. It is possible. When My Uta 104 is selected, music selection referring to the My Uta table is performed. When My Artist 105 is selected, music selection is performed referring to the My Artist table. When Reki 106 is selected, music selection is performed referring to the history table. Is executed. Furthermore, in this embodiment, a recommended music selection field 107 is provided on this My Room screen. The user can select the music to be reserved by selecting the music displayed in this column 107. The selection of music displayed in the column 107 (recommended music selection processing) will be described in detail later.

  FIG. 7 is a diagram showing a my song selection screen when the operation button of the my song 104 is operated on the my room screen of FIG. My song selection refers to the song table in the user information of the active user (in this case, user A) as described above, and the song related information corresponding to the song identifier in the song table is displayed. In this example, the song name and singer name are displayed as the song related information to be displayed. The user can call a previously registered music on this song selection screen, specify a desired music, and reserve a performance.

  FIG. 8 is a diagram showing a music confirmation screen according to the embodiment of the present invention. When a song is designated using an appropriate song selection method such as the My Uta song selection screen in FIG. 7, the song singer name, song name, singing, etc. are displayed to confirm that the song designation is correct. A screen is displayed. If there is no mistake, the reservation button displayed at the lower right of the screen is operated, and the performance reservation for the music is executed.

  Here, in the case of designation by the logged-in user (active user), the music confirmation screen shown in FIG. 8 is displayed. On the right side of the song name column, a “My Uta Registration” operation button is displayed. If the user wants to use the selected music in the future, the user can register the music displayed on the music confirmation screen in the my song table in the user information by operating this operation button. Similarly, a singer can be registered in the My Artist table by operating the “My Artist” operation button displayed at the right end of the singer name column. The singer registered in the my artist table can be called by operating the operation button of the my artist 105 in FIG. 6, and by further reading the singer's song (held song), the singer's song Can be specified.

  Now, a recommendation process for recommending music in the present invention will be described. The recommended processing of the present embodiment is that when a plurality of users gather to perform karaoke, a user with a small number of reservations is determined to be a low tone user (a user who is not excited), and music that is assumed to be of interest to the low tone user Is going to be recommended. The recommended music is displayed in the recommended music selection field 107 in FIG. In particular, in this embodiment, the music corresponding to both the user information of the low tone user and the user information of the other user is displayed as the recommended music, and the music that the low tone user likes or knows is easily played. . By playing the recommended music, it becomes easier for low-key users to participate in the karaoke place, and it is possible to improve the atmosphere of the karaoke place.

  Then, the recommended music selection process which comprises a recommendation process is demonstrated using FIGS. 9-11. FIG. 9 is a flowchart showing recommended music selection processing according to the embodiment of the present invention, FIG. 10 is a flowchart showing low tone user extraction processing according to the embodiment of the present invention, and FIG. It is a figure for demonstrating the low tone user extraction process which concerns on this embodiment.

  The recommended music selection process shown in FIG. 9 is a process started after the commander 2 is started. Note that a program for executing the recommended music selection process may be provided via various recording media or a communication line. First, in step S300, a low tone user extraction process is started, and a user whose number of music reservations is less than a predetermined number is extracted. FIG. 10 shows a flowchart of this undertone user extraction process, and FIG. 11 shows the situation of a plurality of users who log in to the same commander 2 and perform karaoke. When the undertone user extraction process is started, one monitoring target user is extracted from the currently logged-in users (S301). In the present embodiment, immediately after the user starts logging in, the fixed time S is excluded from the monitoring target users, so that a user who has just logged in and has no music reservation is regarded as a low tone user and is erroneously detected.

In FIG. 10, a certain time S after each user logs in is a period for preventing this erroneous detection. For example, the users A, B, and C are logged in at the time T1, but are excluded from the monitoring target users because all the users are in the predetermined time S. At time T2, users D and E are newly logged in. At this time, the users A, B, and C are monitored users because the predetermined time S has ended. On the other hand, the users D and E are excluded from the monitoring target users because they are in the state of the predetermined time S. At time T3, all users A to E are set as monitoring target users.

  In S301, one user is extracted from such monitoring target users. In S302, for the extracted monitoring target user, the number of reserved songs after logging in is acquired. When an active user is reserved in FIG. 8, reservation information including the music identifier of the music to be reserved and the user ID of the active user is stored in the reservation table managed by the commander 2. The commander 2 sequentially executes the music based on the reservation information registered in the reservation table. Based on the reservation table of the commander 2, it is possible to acquire the number of reserved songs of the monitoring target user.

  In FIG. 11, the time indicated by the triangle is the timing at which each user makes a music reservation, and the number of reserved music for user A is 3 and the number of reserved music for user B until time T2 including the user in the monitoring target period. 2 and the number of reserved songs for user C is 0. Until time T3, the number of reserved songs for user A is 4, the number of reserved songs for user B is 2, the number of reserved songs for user C is 2, the number of reserved songs for user D is 2, and the number of reserved songs for user E is 1

  In S303, it is determined whether or not the number of reserved songs of the monitoring target user currently extracted is equal to or less than a predetermined value. In the present embodiment, a user whose reserved music number is 1 or less is determined as a low tone user. The process ends when the processes of S301 to S304 are executed for all the monitoring target users (S305: YES). At time T2 in FIG. 11, the user C is determined as a low-tone user, and at time T3, the user E is determined as a low tone user. In this embodiment, the number of reserved songs after logging in is used for the extraction of undertone users, but in addition to this, the number of reserved songs in a period that goes back a predetermined time from the current time can be used. It is conceivable to use the average number of reserved songs per hour (reservation frequency). Furthermore, in addition to setting the number of reserved songs to be equal to or less than a predetermined number, it is also conceivable to extract a low tone user based on the ranking of the number of reserved songs such as a user having the smallest number of reserved songs.

  Returning to the flowchart of FIG. 9, when a low tone user is extracted in S <b> 300, the process proceeds to the subsequent processing in S <b> 201. In S202, first, user information of the undertone user is extracted. In the example of FIG. 12, there is one undertone user for each of time T2 and time T3, but a plurality of undertone users may be extracted.

  Next, a user other than the low tone user is extracted as a recommended user (S203), and user information of the user is extracted (S204). In S205, the my song table in the user information extracted in S202 is compared with the my song table in the user information extracted in S204, and a matching music piece is extracted. If there is no matching song (S206: No), it is determined whether or not the song of the singer in the my artist table of the target user of the subtone is not in the my song table of the recommended user. If it is not in this determination (S207: No), the music in the my song table of the undertone user is extracted (S208).

  In S209, from the music related to both the low tone user and the recommended user extracted in S206 to S208, or the music described in the My Uta table of the low tone user, the music to be displayed as the recommended music has already been reserved, When the crotch has been played, these music pieces are excluded, and the remaining music pieces are designated as recommended music pieces for the recommended user. If all of the music pieces to be displayed as recommended music pieces have been reserved or played, it is displayed in this case that there is no recommended music piece.

As described above, in the present embodiment, music that has already been reserved and will be played in the future or that has already been played is excluded, so that the music is not played repeatedly. In this embodiment, the music related information of the designated recommended music (in this example, the music name, singer name) is displayed in the recommended music selection field 107 of the recommended target user's My Room screen (FIG. 6). I am going to do that. The processing of S203 to S210 is continued until it is executed for all other users except the low tone user (S211). By repeating the above processing every predetermined time (S212), the extraction of the low tone user and the recommended music are designated regularly.

  In this embodiment, the recommended music is displayed on the My Room screen of the recommended target user. However, the display of the recommended music is not limited to this My Room screen, for example, the top for the guest user in FIG. It may be displayed on the screen, or music related information such as music name, singer name, music identifier, etc. may be displayed on the monitor 4 controlled to be displayed by the commander 2 at the timing of the music performance. .

  In this embodiment, the music that is common between the low tone user and the recommended user is designated as the recommended music for the My Uta table and the My Artist table, but in addition to this, the music stored in the history table is used. Also good. And between a low tone user and a recommendation object user, it is good also as extracting a recommendation music between the tables from which a kind differs.

  As described above, in the present invention, a low-tone user is detected based on the number of music reservations, and music that the low-tone user likes is displayed. In particular, in this embodiment, the music related information of the music that has the same taste as other users is displayed as the recommended music on the other user's My Room screen, and the other user is prompted to reserve the music. It is said. In this way, the low tone user likes and the other user's favorite music is to be designated to other users, and when the recommended music is played, It becomes easy to participate in the karaoke place, and it becomes possible to improve the atmosphere of the entire user who gathers in the karaoke place.

  Note that the present invention is not limited to these embodiments, and embodiments configured by appropriately combining the configurations of the respective embodiments also fall within the scope of the present invention.
