Description

The present invention relates to a karaoke device.

When karaoke singing is performed by a plurality of users, each user selects a song to be karaoke sung via a remote control device or the like. The karaoke device registers the music selected by the user in the reservation queue and performs the karaoke performance in order.

Here, when a large number of people perform karaoke singing, such as in a karaoke cafe, reservations for karaoke songs are frequently made. Therefore, since the karaoke music reserved by a certain user is registered at the lower level of the reservation queue, it is necessary to wait for a long time before the actual karaoke singing is performed.

In response to such a problem, for example, in Patent Document 1, a user who intends to reserve a new musical piece is reserved based on the performance time information of the music currently registered in the reservation queue. A technique for notifying the scheduled required time until the start of performance of a musical piece or the scheduled start time of performance is disclosed.

Further, Patent Document 2 is used by displaying the time until the start of performance of the music reserved by the user's portable communication terminal and the number of remaining songs based on the performance song information transmitted from the karaoke device. A technique is disclosed that allows a person to grasp information waiting for a performance.

(Software configuration)
FIG. 2 is a diagram showing a software configuration example of the karaoke main body 10. The karaoke body 10 includes a reservation registration unit 100, a total performance time calculation unit 200, a shortening setting unit 300, and a performance processing unit 400. The reservation registration unit 100, the total performance time calculation unit 200, the shortening setting unit 300, and the performance processing unit 400 are realized by the CPU 11a executing a program stored in the memory 11b.

[Reservation Registration Department]
The reservation registration unit 100 performs various processes related to music reservation, such as music reservation registration.

The music registered for reservation is a music that the user wishes to sing karaoke. The music to be reserved and registered is selected by the user using the remote control device 50. The remote control device 50 transmits a music ID or the like corresponding to the selected music to the karaoke main body 10. The karaoke main body 10 registers the received music ID in the reservation queue. The reservation queue is provided, for example, as part of the storage area of storage unit 13. The music ID registered in the reservation queue may be associated with a user ID for identifying the user who selected the music. The user ID is obtained when the user logs in to the karaoke device 1 via the remote controller device 50.

The reservation registration unit 100 reads out the music IDs in the order of registration in the reservation queue and outputs the music IDs to the performance processing unit 400. Then, the reservation registration unit 100 deletes the music ID of the reserved music output to the performance processing unit 400 from the reservation queue.

[Total playing time calculation unit]
Each time a new song is registered in the reservation queue, the total playing time calculation unit 200 calculates the remaining playing time of the currently playing song and / or the playing time of the song already registered in the reservation queue. Calculate the total playing time.

The total playing time corresponds to the real time from the time when a new song is registered in the reservation queue until the karaoke singing of the new song becomes possible (until the karaoke performance of the new song starts). To do.

A specific example of calculating the total playing time will be described with reference to FIG. As shown in FIG. 3, it is assumed that a new song I is reserved in a situation where there is a song A currently being played and songs B to H are registered in the reservation queue.

In this case, the total playing time calculation unit 200 calculates the total playing time (32 minutes 57 seconds) by summing the remaining playing time of the music A (3 minutes 37 seconds) and the playing time of each of the music B to H. ..

In addition, a song that is being played in karaoke when a new song is registered, such as when a new song is registered after the performance of a certain song is completed and before the performance of the next reserved song is started. It may not be there. In this case, the total playing time calculation unit 200 calculates the total playing time by totaling only the playing times of the songs already registered in the reservation queue.

The total playing time calculation unit 200 outputs the calculated total playing time to the shortening setting unit 300.

[Short setting section]
The shortening setting unit 300 compares the preset singing waiting time with the total playing time, and when the total playing time is longer than the singing waiting time, the shortening setting unit 300 is currently playing so that the total playing time is equal to or less than the singing waiting time. Reduce the playing time of existing songs and / or songs already registered in the reservation queue.

The singing waiting time corresponds to the maximum value (threshold value of whether or not to shorten the playing time) of the waiting time from the reservation of the music to the karaoke singing of the music. The singing waiting time is set by, for example, an employee of a karaoke cafe or the like inputting via the remote controller 50 in consideration of the age and gender of the user, the singing tendency so far, and the like. Alternatively, a predetermined time may be preset as a singing waiting time for each karaoke device.

When the total playing time is input from the total playing time calculation unit 200, the shortening setting unit 300 compares the singing waiting time with the total playing time. When the total playing time is shorter than the singing waiting time, the shortening setting unit 300 does not perform any special processing.

On the other hand, when the total playing time is longer than the singing waiting time, the user cannot sing karaoke of the song reserved by himself / herself without waiting for a long time. Therefore, in the present embodiment, the shortening setting unit 300 shortens the playing time of the music currently being played and / or the music already registered in the reservation queue so that the total playing time is equal to or less than the singing waiting time. ..

Here, the process of shortening the playing time will be described with reference to FIGS. 3 to 6. In this example, it is assumed that "30 minutes" is set as the singing waiting time and "32 minutes 57 seconds" is input as the total playing time (see the example of FIG. 3).

In this case, the shortening setting unit 300 determines that the total playing time is "2 minutes 57 seconds" longer than the singing waiting time. Therefore, the shortening setting unit 300 sets to shorten the playing time of the currently played music and / or the music already registered in the reservation queue by at least "2 minutes 57 seconds".

Specifically, the shortening setting unit 300 refers to the performance time shortening information (see FIG. 3) of each song registered in the reservation queue, and identifies a song whose playing time can be shortened. In the example of FIG. 3, among the songs A to H, the songs having a shortenable time are the songs B to D, F, and H.

Then, the shortening setting unit 300 can set to shorten the playing time in order from the music having the longest time by referring to the shortenable time (see FIG. 3) of each specified music.

In the above example, the shortening setting unit 300 selects music D and music H in order from the music having the longest shortenable time so that the playing time can be shortened by "2 minutes 57 seconds" or more, and shortens the playing time for each music. Make the settings.

FIG. 4 is a diagram showing the result of performing the shortening setting. As is clear from this figure, by shortening the playing time of the songs D and H, the total playing time after setting the shortening is shortened by 3 minutes to "29 minutes 57 seconds". In this case, the user who has reserved the music I can sing karaoke within the singing waiting time (30 minutes).

The karaoke device 1 can repeat the same process even when a new song is registered again after the shortening setting is performed.

For example, suppose that after the music I is registered in the reservation queue, a new music J is reserved while the music A is playing (FIG. 5).

In this case, the total playing time calculation unit 200 totals the remaining playing time (1 minute 5 seconds) of the currently playing song A and the playing time of the songs B to I already registered in the reservation queue. The total playing time (31 minutes and 40 seconds) is calculated.

After that, the shortening setting unit 300 sets to shorten the playing time of the songs B to I already registered in the reservation queue so that the total playing time (31 minutes and 40 seconds) is equal to or less than the singing waiting time (30 minutes). I do. At this time, the shortening setting unit 300 selects a music that can be shortened other than the music D and H for which the shortening setting has already been performed, and performs the shortening setting.

In this example, a reduction of "1 minute 40 seconds" is required. Therefore, the shortening setting unit 300 sequentially selects songs B and C having a long shortenable time other than the songs D and H, and sets the playing time for each song to be shortened.

FIG. 6 is a diagram showing the result of performing the shortening setting. As is clear from this figure, by shortening the playing time of the songs B and C, the total playing time after setting the shortening is shortened by 1 minute 57 seconds to "29 minutes 23 seconds". In this case, the user who has reserved the music J can sing karaoke within the singing waiting time (30 minutes).

In the above example, an example of shortening the playing time of a song already registered in the reservation queue has been described, but when the remaining playing time of the currently playing song can be set to be shortened (for example, a follow-up cut). If the setting is possible), the playing time may be shortened for the currently played music.

By the way, even if the shortenable times of the songs registered in the reservation queue are totaled, the shortened time may not be enough.

Therefore, the shortening setting unit 300 sings even if the shortening of the playing time is set for all the songs currently being played and the songs already registered in the reservation queue that can shorten the playing time. When the waiting time becomes longer than the predetermined time, the total playing time after setting the shortening of the playing time can be notified. Such a total playing time corresponds to a singing waiting time.

The total playing time can be notified by various methods. For example, the shortening setting unit 300 notifies by displaying a message such as "You can sing in ●● minutes" on the display screen of the display device 30 or the remote control device 50 at the timing when the music is reserved. Alternatively, the shortening setting unit 300 may emit the above message as a voice through the speaker 20.

In addition to the above-mentioned method of setting the shortening of the playing time in order from the music having the longest shortenable time, various methods can be used.

For example, the shortening setting unit 300 shortens the playing time by selecting a predetermined song from the songs whose playing time can be shortened so that the shortened playing time approximates the difference between the predetermined time and the singing waiting time. It is also possible to make settings.

Similar to the above example, it is assumed that the shortening setting unit 300 determines that the total playing time is "2 minutes 57 seconds" longer than the singing waiting time. In this case, the shortening setting unit 300 selects the music so that the shortened playing time approximates the difference "2 minutes 57 seconds". For example, in the example of FIG. 3, the total shortenable time of the songs B, C, and F is exactly 2 minutes 57 seconds. Therefore, the shortening setting unit 300 selects songs B, C, and F as predetermined songs, and sets each to shorten the playing time.

Alternatively, as another method, the shortening setting unit 300 plays in order from the songs reserved by the user with the most singing times among the songs whose playing time can be shortened based on the number of singing times of each user in a certain period. It is also possible to make settings to shorten the time.

A certain period is a predetermined period for counting the number of singing, and may be a continuous period from the opening of the karaoke cafe to the present time, or has a predetermined range such as every 3 hours or every 6 hours. It may be a period.

Each time a song is registered in the reservation queue in a certain period, the karaoke device 1 refers to the user ID associated with the song and counts the number of singing times of each user.

Then, when the shortening setting unit 300 determines that the total playing time is longer than the singing waiting time, the user ID of the user who sings a large number of times is set based on the number of singing times of each user obtained so far. Identify. Then, when the music associated with the specified user ID is registered in the reservation queue and the music is a music whose playing time can be shortened, the shortening setting unit 300 determines the music. Make settings to shorten the playing time of.

[Performance processing unit]
The performance processing unit 400 performs karaoke performance of the music.

Specifically, when the performance processing unit 400 receives the input of the music ID of the music registered from the reservation registration unit 100, the performance processing unit 400 reads the music data corresponding to the music ID from the storage unit 13 and performs the karaoke performance of the music. For the music for which the shortening setting is made by the shortening setting unit 300, the performance processing unit 400 shortens the playing time and performs karaoke performance. Specifically, the playing time is shortened by executing functions such as 2 chorus fade-out and after-play cut.

== About the operation of the karaoke device 1 ==
Next, a specific example of the operation of the karaoke device 1 in the present embodiment will be described with reference to FIG. 7. FIG. 7 is a flowchart showing an operation example of the karaoke device 1. In this example, an example in which a new song is registered in the reservation queue during a karaoke performance of a certain song will be described.

The reservation registration unit 100 registers the music selected by the user in the reservation queue (music reservation. Step 10).

Each time a new song is registered in the reservation queue, the total playing time calculation unit 200 totals the remaining playing time of the currently playing song and the playing time of the song already registered in the reservation queue. The total playing time is calculated (calculation of the total playing time. Step 11). The total playing time calculation unit 200 outputs the calculated total playing time to the shortening setting unit 300.

The shortening setting unit 300 compares the singing waiting time with the total playing time calculated in step 11 (comparison between the singing waiting time and the total playing time. Step 12).

If the total playing time is longer than the singing waiting time (Y in step 13), the shortening setting unit 300 has already set the total playing time to be less than or equal to the singing waiting time in the currently played song or reservation queue. Make a setting to shorten the playing time of the registered music (setting to shorten the playing time. Step 14).

The performance processing unit 400 performs a karaoke performance of the music registered in the reservation queue (Karaoke performance. Step 15). At this time, if the total playing time is longer than the singing waiting time (in the case of Y in step 13), the performance processing unit 400 shortens the playing time for the music set to shorten the playing time in step 14. Perform karaoke performance. On the other hand, when the total playing time is shorter than the singing waiting time (when N is set in step 13), the performance processing unit 400 performs the karaoke performance with the preset playing time.

As described above, the karaoke device 1 according to the present embodiment is already registered in the reservation queue for the remaining playing time and / or the reservation queue each time a new song is registered in the reservation queue. When the singing waiting time calculation unit 200, which calculates the total playing time of the existing songs, compares the preset singing waiting time with the total playing time, and the total playing time is longer than the singing waiting time, It has a shortening setting unit 300 that sets to shorten the playing time of the music currently being played and / or the music already registered in the reservation queue so that the total playing time is equal to or less than the singing waiting time.

With such a configuration, if it takes a long time to play the reserved song in karaoke, the total playing time can be set to be less than or equal to the singing waiting time by shortening the playing time of the already reserved song. it can. Therefore, according to the karaoke device 1 according to the present embodiment, karaoke singing can be performed within a preset time even when there are many reserved songs. In this case, the user who has reserved the music does not have to wait for a long time before singing the karaoke song, so that the user can enjoy the karaoke singing.

In addition, even if the playing time is set to be shortened for all the songs currently being played and the songs already registered in the reservation queue that can shorten the playing time, the total playing time is the singing waiting time. If it is longer than, the shortening setting unit 300 can notify the total playing time after setting the shortening of the playing time. According to such a karaoke device 1, even if the karaoke cannot be sung within the singing waiting time, the user can grasp the approximate time during which the karaoke song reserved by the user can be sung.
