The karaoke main body 10 performs various controls related to karaoke performance and karaoke singing, such as performance control of selected songs, display control of lyrics and background images, and processing of audio signals input through a microphone 40. The speaker 20 is configured to emit sound based on the sound emitted signal from the karaoke main body 10. The display device 30 is configured to display an image or an image on the screen based on the signal from the karaoke body 10. The microphone 40 is configured to convert the user's singing voice into an analog voice signal and input it to the karaoke main body 10. The remote control device 50 is a device for performing various operations on the karaoke main body 10.

As shown in FIG. 2, the karaoke main body 10 according to the present embodiment includes storage means 10a, communication means 10b, input means 10c, and control means 10d. Each configuration is connected to bus B via an interface (not shown).

[Memory means]
The storage means 10a is a large-capacity storage device that stores various types of data, such as a hard disk drive. The storage means 10a stores a plurality of music data for performing karaoke performance by the karaoke device K.

Music identification information for identifying individual music is added to the music data. The music identification information is information unique to each music, such as a music ID for identifying the 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 a user. The playing time of the karaoke performance is preset for each song.

Further, the storage means 10a according to the present embodiment stores table data related to the shortened performance mode (details will be described later).

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

[Control means]
The control means 10d performs various controls on the karaoke device K. The control means 10d includes a CPU and a memory (neither of which is shown). The CPU realizes various functions by executing a program stored in the memory.

In the present embodiment, the control means 10d functions as a login processing unit 100, an acquisition unit 200, a selection unit 300, and a performance control unit 400 by executing a program stored in the memory by the CPU.

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

For example, the user inputs the user identification information via the remote control device 50 of the karaoke device K. The user identification information is a unique identifier for identifying the user, such as a user ID. Based on the operation input from the user, the login processing unit 100 completes the login of the user to the karaoke device K by storing the user identification information in the storage means 10a. In the present embodiment, it is assumed that a plurality of users are logged in to the karaoke device K.

Here, the logged-in user makes a reservation for a song to be sung by the karaoke via the remote controller 50. The storage means 10a associates the user ID of the user who reserved the music with the music ID of the music and stores it in the reservation queue.

On the other hand, when the logged-in user stops using the karaoke device K, an operation input (log-out operation input) to delete his / her own user identification information is performed via the remote control device 50. Based on the operation input from the user, the login processing unit 100 completes the log-out of the user to the karaoke device K by deleting the user identification information of the user stored in the storage means 10a.

(Acquisition department)
The acquisition unit 200 acquires the number of users, which is the number of users who use the karaoke device K. The number of users can be obtained by various methods.

As an example, the acquisition unit 200 acquires the number of logged-in users as the number of users. In this case, the acquisition unit 200 can acquire the number of users each time there is a login or logout.

For example, suppose that the user U1 to the user U4 are logged in to the karaoke device K, and the user U5 inputs a login operation to the karaoke device K. In this case, the login processing unit 100 completes the login of the user U5 to the karaoke device K.

At this time, the acquisition unit 200 counts the number of user identification information stored in the storage means 10a, and acquires "5 people" as the number of users.

On the other hand, it is assumed that the user U1 to the user U5 are logged in to the karaoke device K, and the user U1 inputs a logout operation to the karaoke device K. In this case, the login processing unit 100 completes the logout of the user U1 to the karaoke device K.

At this time, the acquisition unit 200 counts the number of user identification information stored in the storage means 10a, and acquires "4 people" as the number of users.

Alternatively, the acquisition unit 200 is a user who is logged in at that time immediately before the karaoke performance of the first reserved song is started, or when the user gives an instruction to start the karaoke performance of the song. The number of users may be obtained as the number of users. The user gives an instruction to start the karaoke performance by operating the remote controller device 50.

Further, as another example, the acquisition unit 200 is based on the user identification information included in the reservation queue that links the user identification information indicating the user who is reserving the music and the music identification information indicating the music. The number of users can be obtained.

For example, it is assumed that five users U1 to U5 are logged in to the karaoke device K. On the other hand, it is assumed that the reservation queue of the storage means 10a includes only the music reserved by the users U1 to U3 and the music reserved by the user U5. That is, the user U4 is logged in to the karaoke device K, but the music is not reserved. Therefore, it is not necessary to consider the singing waiting time for the user U4.

Therefore, the acquisition unit 200 acquires "4 people" as the number of users based on the user IDs of the users U1 to U3 and the user U5 included in the reservation queue.

(Selection part)
The selection unit 300 selects the shortened performance mode when the acquired number of users satisfies the predetermined condition, and selects the normal performance mode when the acquired number of users does not satisfy the predetermined condition.

The shortened performance mode is a mode for shortening the playing time of a karaoke performance preset for each song. How to shorten the playing time is preset, for example, "after 2 choruses, fade out", "interlude cut", and the like. Further, as the performance shortening mode, one mode may be set, or a plurality of modes having different shortened playing times may be set. When having a plurality of shortened performance modes, each shortened performance mode is set according to the number of users.

The normal performance mode is a mode in which a karaoke performance is performed at a performance time preset for each song.

The predetermined condition is a condition that serves as a reference for selecting either the shortened performance mode or the normal performance mode. Predetermined conditions are determined based on the number of users. For example, in the case of a predetermined condition that "the number of users is 3 or more", the selection unit 300 selects the shortened performance mode when the number of acquired users is 4, and the number of acquired users is 2. In the case of, select the normal performance mode.

Further, when a plurality of shortened performance modes are set, the selection unit 300 selects one shortened performance mode from the plurality of shortened performance modes according to the number of users when the acquired number of users satisfies a predetermined condition. select.

For example, it is assumed that the storage means 10a stores the table data shown in FIG. The table data shown in FIG. 3 defines the relationship between the shortened performance mode in which the karaoke device K can be executed and the number of users. According to the example of FIG. 3, as the number of users increases, the playing time of one song becomes shorter. Further, it is assumed that "the number of users is 3 or more" is set as a predetermined condition. In this example, "2 chorus fade-out" is shorter than the normal performance mode because the prelude, 1st, interlude, and 2 are played to fade out, and "2 chorus fade-out and interlude cut" is the prelude, 1 The playing time is even shorter than "2 chorus fade-out" because the number 2 is played and faded out without playing the interlude after playing the number. The performance time of "1 chorus fade-out" is even shorter than that of "2 chorus fade-out and interlude cut" because the prelude No. 1 is played to fade out.

Here, when the acquired number of users is "5", the selection unit 300 refers to the table data of FIG. 3 and selects "2 chorus fade-out and interlude cut" as the shortened performance mode. On the other hand, when the acquired number of users is "8", the selection unit 300 refers to the table data of FIG. 3 and selects "1 chorus fade-out" as the shortened performance mode. In this example, when the number of acquired users is two or less, the selection unit 300 selects the normal performance mode.

(Performance control unit)
The performance control unit 400 performs karaoke performance based on the accompaniment data of the music. Specifically, the performance control unit 400 reads the accompaniment data from the storage means 10a, generates a performance sound based on the accompaniment data, and emits the sound from the speaker 20.

The performance control unit 400 according to the present embodiment has different performance modes (shortened performance mode and normal performance mode), and performs karaoke performance based on the selected shortened performance mode or normal performance mode.

Further, when there are a plurality of shortened performance modes as described above, the performance control unit 400 can perform karaoke performance in a plurality of shortened performance modes having different shortened playing times.

For example, it is assumed that the shortened performance mode is selected by the selection unit 300. In this case, the performance control unit 400 shortens the playing time for all the karaoke performances of the music reserved by the user and performs the karaoke performance.

== Processing in karaoke equipment ==
Next, the process in the karaoke device K according to the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing processing in the karaoke device K. In this example, it is assumed that a group of users who have entered a karaoke store uses one karaoke device K in the karaoke room.

After logging in, each user makes a reservation for a song for which he / she sings karaoke. In addition, each user inputs a log-out instruction when stopping the use of the karaoke device K.

The acquisition unit 200 acquires the number of users who use the karaoke device K according to the login or logout of the user (acquisition of the number of users. Step 11).

The selection unit 300 determines whether or not the number of users acquired in step 11 satisfies a predetermined condition.

When the acquired number of users satisfies a predetermined condition (Y in step 12), the selection unit 300 selects a shortened performance mode for shortening the playing time of the karaoke performance for each song (selection of the shortened performance mode. Step. 13). On the other hand, when the acquired number of users does not satisfy the predetermined condition (when N in step 12), the selection unit 300 selects a normal performance mode in which the karaoke performance is performed at the performance time of each song (selection of the normal performance mode). Step 14).

After that, it is assumed that one user inputs an instruction to start karaoke performance via the remote control device 50 (instruction to start karaoke performance. Step 15).

The performance control unit 400 performs a karaoke performance based on the performance mode selected in step 13 or 14 (Karaoke performance based on the selected performance mode. Step 16).

The karaoke device K repeats the processes of steps 10 to 16 until all users log out (in the case of Y in step 17).

As is clear from the above, in the karaoke device K according to the present embodiment, the acquisition unit 200 for acquiring the number of users, which is the number of users using the karaoke device K, and the acquired number of users satisfy a predetermined condition. In this case, a shortened performance mode that shortens the playing time of the karaoke performance preset for each song is selected, and if the acquired number of users does not meet the predetermined conditions, it is preset for each song. A selection unit 300 for selecting a normal performance mode for performing karaoke performance according to the playing time, and a performance control unit 400 having a shortened performance mode and a normal performance mode for performing karaoke performance based on the selected shortened performance mode or normal performance mode. Have.

According to such a karaoke device K, when the number of users is large, the playing time for each song can be shortened. Therefore, even if the number of users is large, the singing waiting time does not become long. On the other hand, when the number of users is small, the karaoke performance is performed at a preset performance time, so that the performance time is not shortened even when the number of music reservations increases. That is, according to the karaoke device K according to the present embodiment, the singing waiting time can be shortened according to the number of users.

Further, the performance control unit 400 in the karaoke apparatus K according to the present embodiment has a plurality of shortened performance modes having different shortened playing times, and the selection unit 300 determines that the acquired number of users satisfies a predetermined condition. One shortened performance mode can be selected from a plurality of shortened performance modes according to the number of users. By selecting the shortened performance mode according to the number of users in this way, the karaoke device K can set the singing waiting time more finely.

Further, the karaoke device K according to the present embodiment has a login processing unit 100 for logging in to the karaoke device K, and the acquisition unit 200 acquires the number of logged-in users as the number of users. .. By using the login information by the user in this way, the karaoke device K can easily grasp the number of users.

Further, the acquisition unit 200 in the karaoke device K according to the present embodiment is a user included in a reservation queue in which user identification information indicating a user who is reserving a song and music identification information indicating the song are linked. The number of users can be obtained based on the identification information.
