Description

  The present invention relates to a karaoke apparatus.

  When performing karaoke singing 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 karaoke performance in order.

  Here, for example, when performing karaoke singing in large numbers like karaoke cafes, reservation of karaoke music is frequently performed. Therefore, since a karaoke piece reserved by a certain user is registered in the lower part of the reservation queue, the user waits for a long time before performing an actual karaoke song.

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

  Further, in Patent Document 2, based on the performance music information transmitted from the karaoke device, the time until the performance start of the music reserved at the user's portable communication terminal and the number of remaining music are displayed. A technique for allowing a user to grasp performance waiting information is disclosed.

  In addition to the main invention described above, at least the following matters will become apparent from the description of the specification and drawings described below.

  That is, the karaoke apparatus in which the shortening setting unit performs the setting for shortening the performance time in order from the music having the longest possible shortening time among the music whose performance time can be shortened becomes clear. By performing the setting for shortening the performance time in this way, karaoke singing can be reliably performed within a preset singing waiting time.

  In addition, the shortening setting unit selects and plays a predetermined piece of music from among the pieces of music that can shorten the performance time so that the performance time to be shortened approximates the difference between the singing waiting time and the expected waiting time. A karaoke device that makes settings for shortening the time becomes clear. By performing the setting for shortening the performance time in this way, the performance time is not shortened more than necessary.

  In addition, based on the number of singing times of each user in a certain period, the shortening setting unit sets the performance times in order from the music reserved by the user with the highest number of singing times among the songs whose performance time can be shortened. A karaoke device with a setting for shortening becomes clear. By performing the setting for shortening the performance time in this way, it is possible to equalize the singing time for each user.

  In addition, the shortening setting unit performs the setting for shortening the performance time for all the songs that can be shortened in the performance time among the currently played music and the music already registered in the reservation queue. However, when the expected waiting time is longer than the singing waiting time, a karaoke device that notifies the expected waiting time after setting the shortening of the performance time becomes clear. According to such a karaoke apparatus, it can notify a user that karaoke singing cannot be performed within a singing waiting time.

  Alternatively, in a state where the first music set for shortening the performance time is registered in the reservation queue, the reservation of the second music registered after the first music is canceled. In this case, the first comparison unit that compares the shortenable time of the first music and the performance time of the second music, and the performance time of the second music is shortened. When it is longer than the possible time, for the music reserved between the first music and the second music, the expected waiting time when the shortening setting is canceled is compared with the singing waiting time. And the shortening setting unit has an expected waiting time when canceling the shortening setting for all the songs reserved between the first song and the second song. If it is less than the singing waiting time, the first music piece Karaoke apparatus for releasing a shortened setting becomes apparent. According to such a karaoke device, when the reservation is canceled, it is possible to perform karaoke singing within the singing waiting time set in advance for all the remaining reserved music while returning the shortened performance time to the original. can do.

<First Embodiment>
With reference to FIGS. 1-8, the karaoke apparatus 1 which concerns on 1st Embodiment is demonstrated.

== Karaoke equipment ==
The karaoke apparatus 1 is an apparatus for performing karaoke performance and karaoke singing by a user. The karaoke apparatus 1 registers the music pieces selected by the user in the reservation queue and performs karaoke performances in order. As shown in FIG. 1, the karaoke apparatus 1 includes a karaoke main body 10, a speaker 20, a display device 30, a microphone 40, and a remote control device 50.

  The speaker 20 is configured to emit sound based on the sound emission signal from the karaoke main body 10. The display device 30 is configured to display a video or an image on the screen based on a signal from the karaoke main body 10. The microphone 40 is configured to convert a user's singing voice (input voice from the microphone 40) 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. The user can use the remote controller 50 to select a song (reservation) or the like for a song for which karaoke singing is desired. Icons or the like for inputting instructions for various operations are displayed on the display screen of the remote control device 50.

  The karaoke main body 10 performs various controls related to karaoke singing, such as karaoke performance control of the selected music, display control of lyrics and background images, and processing of audio signals input through the microphone 40. As shown in FIG. 1, the karaoke main body 10 includes a control unit 11, a communication unit 12, a storage unit 13, an acoustic processing unit 14, a display processing unit 15, and an operation unit 16. Each component is connected to the bus B via an interface (not shown).

  The control unit 11 includes a CPU 11a and a memory 11b. The CPU 11a implements various control functions by executing the operation program stored in the memory 11b. The memory 11b is a storage device that stores a program to be executed by the CPU 11a and temporarily stores various types of information when the program is executed.

  The communication unit 12 provides an interface for connecting the karaoke main unit 10 to a communication line via a router (not shown).

  The storage unit 13 is a large-capacity storage device that stores various data, and is, for example, a hard disk drive. The storage unit 13 stores a plurality of pieces of music data for performing karaoke performance by the karaoke apparatus 1.

  The music data is given a music ID for specifying individual music. The music data includes accompaniment data, reference data, guide melody data, and the like. Accompaniment data is data that is the source of karaoke performance sounds. Reference data is data used as a reference when scoring a karaoke song by a user. The guide melody data is data constituting a guide melody that supports the user's karaoke singing.

  The storage unit 13 also includes lyrics telop data for displaying the lyrics telop corresponding to each piece of music on the display device 30, background image data such as a background image displayed on the display device 30 during karaoke performance, Performance time data indicating the karaoke performance time and music attribute information (information on the music such as singer name, lyrics / composer name, genre, etc.) are stored.

  Furthermore, the storage unit 13 according to the present embodiment stores performance time shortening information for each piece of music. The shortening information includes information indicating whether or not the karaoke performance time indicated by the performance time data can be shortened, and when the karaoke performance time can be shortened, includes a time that can be shortened (a shortenable time). The shortenable time corresponds to a time that is shortened when, for example, 2 chorus fade-out, sequel cut, fast-forwarding of a non-singing section, etc., which are functions provided in the karaoke apparatus 1 are executed.

  Based on the control of the control unit 11, the sound processing unit 14 controls karaoke performance for music and processes a singing voice signal input through the microphone 40. The acoustic processing unit 14 includes, for example, a MIDI sound source, a mixer, and an amplifier (all not shown). The MIDI sound source generates a musical sound signal based on the music data. The mixer mixes the music signal and the audio signal output from the microphone 40 at an appropriate ratio and outputs the mixed signal to the amplifier. The amplifier amplifies the mixing signal from the mixer and outputs the amplified signal to the speaker 20 as a sound emission signal. Thereby, the karaoke performance sound based on the sound emission signal and the singing voice from the microphone 40 are emitted from the speaker 20.

  The display processing unit 15 performs processing related to various displays in the display device 30 and the remote control device 50 based on the control of the control unit 11. For example, the display processing unit 15 controls the display device 30 to display a video in which lyrics telop and various icons are superimposed on a background video during karaoke performance. Alternatively, the display processing unit 15 displays various icons for operation input on the display screen of the remote control device 50.

  The operation unit 16 includes a panel switch and a remote control receiving circuit. The operation unit 16 sends operation signals such as a music selection signal and a performance stop signal to the control unit 11 according to the operation of the panel switch of the karaoke device 1 or the remote control device 50 by the user. Output. The control unit 11 detects an operation signal from the operation unit 16 and executes a corresponding process.

(Software configuration)
FIG. 2 is a diagram illustrating a software configuration example of the karaoke main body 10. The karaoke main body 10 includes a reservation registration unit 100, an expected waiting time calculation unit 200, a shortening setting unit 300, and a performance processing unit 400. The reservation registration unit 100, the expected waiting 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 that is reserved and registered is a music that the user desires to sing karaoke. The user selects a song to be reserved and registered using the remote controller 50. The remote control device 50 transmits the song ID corresponding to the selected song 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 as a part of the storage area of the storage unit 13, for example. 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 into the karaoke apparatus 1 via the remote control device 50.

  The reservation registration unit 100 reads out the music IDs and outputs them to the performance processing unit 400 in the order registered in the reservation queue. Then, the reservation registration unit 100 deletes the music ID of the reserved music for which the performance by the performance processing unit 400 has been completed from the reservation queue.

[Expected waiting time calculator]
Each time a new song is registered in the reservation queue, the expected waiting time calculation unit 200 performs the performance start time of the currently played song, the reservation time of the song already registered in the reservation queue, An expected waiting time is calculated on the basis of the playing time of the music being played and the remaining waiting time obtained by adding up the playing times of the music already registered in the reservation queue.

  The expected waiting time is the prediction of the waiting time from when a new song is registered in the reservation queue until karaoke singing of the new song becomes possible (until the karaoke performance of the new song starts). Value.

  Specifically, the expected waiting time is the sum of the fixed waiting time and the remaining waiting time. The fixed waiting time is a time corresponding to the difference between the performance start time of the currently played music and the reserved time of the new music. The remaining waiting time is the sum of the performance time of the currently played music and the performance time of the music already registered in the reservation queue. The remaining waiting time varies depending on the presence or absence of the music shortening setting. That is, the expected waiting time also varies depending on the presence or absence of the music shortening setting (details will be described later).

  A specific example of calculating the expected waiting time will be described with reference to FIGS. 3 and 4A. 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. Note that at the time of reservation of the music H (11:54:00), the performance of the music A has not started, the music reserved before the music A is being played, and the music A is reserved before the performance. Registering. After that, 1 minute and 30 seconds elapse after the reservation of the music H, and the performance of the music A is started. FIG. 3 shows a situation at any point in time from the start of the performance of the music A until the music I is reserved (11:55:30 to 11:55:00). is there.

  In this case, the expected waiting time calculation unit 200 obtains a difference between the performance start time of the music piece A (11:55:30) and the reservation time of the music piece I (11:56:00), -30 seconds). The expected waiting time calculating unit 200 adds the performance time of the music piece A (06:00) and the performance times of the music pieces B to H, and calculates the remaining waiting time (30 minutes and 40 seconds). Then, the expected waiting time calculation unit 200 calculates an expected waiting time (30 minutes and 10 seconds) that is the sum of the determined waiting time (−30 seconds) and the remaining waiting time (30 minutes and 40 seconds) (see FIG. 4A). The expected waiting time calculation unit 200 outputs the calculated expected waiting time to the shortening setting unit 300. The reason why the waiting time for the confirmation of the music I is negative is that the music I is a music reserved 30 seconds after the performance start of the music A.

[Speed setting section]
The shortening setting unit 300 compares the singing waiting time set in advance with the expected waiting time, and when the expected waiting time is longer than the singing waiting time, the shortening setting unit 300 is currently played so that the expected waiting time becomes equal to or less than the singing waiting time. The performance time of the existing music and / or music already registered in the reservation queue is shortened.

  The singing waiting time corresponds to the maximum time (threshold for whether or not to shorten the performance time) to wait until the karaoke singing of the music after the music is reserved. The singing waiting time is set, for example, when a karaoke cafe employee or the like inputs it via the remote control device 50 in consideration of the age and sex of the user, the singing tendency so far, and the like. Or predetermined time may be preset as a singing waiting time for every karaoke apparatus.

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

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

  Here, the performance time shortening process will be described with reference to FIGS. 4A to 7. In this example, when “30 minutes” is set as the singing waiting time, it is assumed that “30 minutes and 10 seconds” is input as the expected waiting time (see FIG. 4A).

  In this case, the shortening setting unit 300 determines that the expected waiting time is “10 seconds” longer than the singing waiting time. Therefore, the shortening setting unit 300 performs setting so as to shorten the performance time of the currently played music and / or the music already registered in the reservation queue by at least “10 seconds”.

  Specifically, the shortening setting unit 300 refers to the performance time shortening information (see FIG. 4A) of each music registered in the reservation queue, and identifies the music that can shorten the performance time. In the example of FIG. 4A, of the songs A to H registered in the reservation queue before the song I, the songs having the time that can be shortened are the song C and the song F.

  And the shortening setting part 300 can perform the setting which shortens performance time in an order from the music with long shortenable time, for example with reference to the shortenable time (refer FIG. 4A) of each specified music.

  In the above example, the shortening setting unit 300 selects the music piece C having a longer shortenable time so that the performance time can be shortened by “10 seconds” or more, and performs the setting to shorten the performance time.

  FIG. 4B is a diagram illustrating a result of performing the shortening setting. As is apparent from this figure, by shortening the performance time of the music piece C, the expected waiting time (remaining waiting time) of the music pieces D to I reserved thereafter is reduced by 2 minutes. For example, the expected waiting time for the music piece I is “28 minutes and 10 seconds”. In this case, the user who reserved the music I can perform karaoke singing within the singing waiting time (30 minutes).

  Note that the karaoke apparatus 1 can repeatedly perform the same processing even when there is a reservation registration of further music after performing the shortening setting.

  For example, it is assumed that a new song J is reserved during the performance of song A. In this case, the expected waiting time calculation unit 200 obtains the difference between the performance start time of the music piece A (11:55:30) and the reserved time of the music piece J (11:57:00), thereby determining the waiting time ( -01 minutes 30 seconds). Further, the expected waiting time calculation unit 200 adds the performance time of the music piece A (06 minutes 00 seconds) and the performance times of the music pieces B to I, and calculates the remaining waiting time (32 minutes and 10 seconds). Then, the expected waiting time calculation unit 200 calculates an expected waiting time (30 minutes and 40 seconds) that is the sum of the fixed waiting time (−01 minutes and 30 seconds) and the remaining waiting time (32 minutes and 10 seconds) (see FIG. 5A). ). The expected waiting time calculation unit 200 outputs the calculated expected waiting time to the shortening setting unit 300. The reason why the waiting time for confirmation of the music J is a negative value is that the music J is a music reserved 1 minute 30 seconds after the performance start of the music A.

  Thereafter, the shortening setting unit 300 shortens the performance time of the songs B to I registered in the reservation queue so that the expected waiting time (30 minutes and 40 seconds) of the song J is equal to or less than the singing waiting time (30 minutes). Set to At this time, the shortening setting unit 300 selects a song that can be shortened other than the song C that has already been shortened, and performs the shortening setting.

  In this example, shortening of “40 seconds” is required. Therefore, the shortening setting unit 300 selects a song F other than the song C that can be shortened and performs a setting to shorten the performance time.

  FIG. 5B is a diagram illustrating a result of performing the shortening setting. As is apparent from this figure, by shortening the performance time of the music F, the expected waiting time (remaining waiting time) of the music G to music J reserved thereafter is shortened by 1 minute 30 seconds. For example, the expected waiting time of the music piece J is “29 minutes 10 seconds”. In this case, the user who reserved the music J can perform karaoke singing within the singing waiting time (30 minutes).

  Similarly, it is assumed that a new song K is reserved during the performance of song A. In this case, the expected waiting time calculation unit 200 obtains the difference between the performance start time of the music piece A (11:55:30) and the reserved time of the music piece K (11:58:00), thereby determining the waiting time ( -02 minutes 30 seconds). The expected waiting time calculating unit 200 adds the performance time of the music piece A (06:00) and the performance times of the music pieces B to J, and calculates the remaining waiting time (32 minutes and 40 seconds). Then, the expected waiting time calculation unit 200 calculates an expected waiting time (30 minutes and 10 seconds) that is the sum of the determined waiting time (-2 minutes and 30 seconds) and the remaining waiting time (32 minutes and 40 seconds) (see FIG. 6A). ). The expected waiting time calculation unit 200 outputs the calculated expected waiting time to the shortening setting unit 300. The reason why the waiting time for determining the music K is negative is that the music K is a music reserved 2 minutes and 30 seconds after the music A starts playing.

  Thereafter, the shortening setting unit 300 shortens the performance time of the songs B to J registered in the reservation queue so that the expected waiting time (30 minutes and 10 seconds) of the song K is equal to or less than the singing waiting time (30 minutes). Perform the settings to be performed. At this time, the abbreviated setting unit 300 selects the music that can be abbreviated other than the music C and F that have already been abbreviated and performs the abbreviated setting.

  In this example, it is necessary to shorten “10 seconds”. Therefore, the shortening setting unit 300 selects a song I that can be shortened other than the songs C and F, and performs settings for shortening the performance time.

  FIG. 6B is a diagram illustrating a result of performing the shortening setting. As is apparent from this figure, by shortening the performance time of the music I, the expected waiting time (remaining waiting time) of the music J and the music K reserved thereafter is reduced by 1 minute 25 seconds. For example, the expected waiting time for the music piece K is “28 minutes 45 seconds”. In this case, the user who reserved the music K can perform karaoke singing within the singing waiting time (30 minutes).

  On the other hand, it is assumed that a new song L is reserved during the performance of the song A. In this case, the expected waiting time calculation unit 200 obtains the difference between the performance start time of the music piece A (11:55:30) and the reserved time of the music piece L (12:00:00), and a fixed waiting time ( -04 minutes 30 seconds). The expected waiting time calculating unit 200 adds the performance time of the music piece A (06 minutes 00 seconds) and the performance times of the music pieces B to K, and calculates the remaining waiting time (33 minutes and 45 seconds). Then, the expected waiting time calculation unit 200 calculates an expected waiting time (29 minutes 15 seconds) that is the sum of the determined waiting time (−04 minutes 30 seconds) and the remaining waiting time (33 minutes 45 seconds) (see FIG. 7). ). The expected waiting time calculation unit 200 outputs the calculated expected waiting time to the shortening setting unit 300. The reason why the waiting time for confirmation of the music L is a negative value is that the music L is a music reserved 4 minutes and 30 seconds after the performance start of the music A.

  Here, the expected waiting time (29 minutes 15 seconds) of the music L is equal to or shorter than the singing waiting time (30 minutes). Therefore, the shortening setting unit 300 does not perform special processing.

  As described above, in this embodiment, during the performance of the music A (between 11:55:30 and 12:01:30), the music I, the music J, the music K, and the music L are reserved and registered. Explained the case. In the above example, the example in which the performance time of the music already registered in the reservation queue is shortened has been described. However, when the remaining performance time of the currently played music can be shortened (for example, after performance) If the cut can be set), the performance time may be shortened for the currently played music.

  By the way, even if the time that can be shortened for the music registered in the reservation queue is totaled, it may be less than the time required for shortening.

  Therefore, even if the shortening setting unit 300 performs the setting for shortening the performance time for all the music that can be shortened in the performance time among the currently played music and the music already registered in the reservation queue, When the waiting time is longer than the expected waiting time, the expected waiting time after performing the setting for shortening the performance time can be notified. Such an expected waiting time corresponds to a singing waiting time.

  The notification of the expected waiting time can be performed 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 message as sound through the speaker 20.

  The performance time can be shortened by various methods other than the above-described method of setting the music piece in order from the music with the longest possible shortening time.

  For example, the shortening setting unit 300 shortens the performance time by selecting a predetermined piece of music from which the performance time can be shortened so that the performance time to be shortened approximates the difference between the expected waiting time and the singing waiting time. It is also possible to make settings.

  Similarly to the above example, it is assumed that the shortening setting unit 300 determines that the expected waiting time is “10 seconds” longer than the singing waiting time. In this case, the shortening setting unit 300 selects the music so that the performance time to be shortened approximates the difference “10 seconds”. For example, in the example of FIG. 3, the shortenable time of the music F is closer to the difference “10 seconds” than the music C. Therefore, the shortening setting unit 300 selects the music F as the predetermined music and performs setting for shortening the performance time.

  Alternatively, as another method, the shortening setting unit 300 performs in order from the music reserved by the user with the highest number of singing among the music whose performance time can be shortened based on the number of times each user sings in a certain period. It is also possible to set to shorten the time.

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

  The karaoke device 1 refers to the user ID associated with the music every time the music is registered in the reservation queue in a certain period, and counts the number of times each user sings.

  When the shortening setting unit 300 determines that the expected waiting time is longer than the singing waiting time, based on the number of singing times of each user obtained so far, the user ID of the user who has a large number of singing times is obtained. Identify. Then, if the music associated with the identified user ID is registered in the reservation queue, and the music is a music capable of shortening the performance time, the music setting section 300 Set to shorten the performance time.

[Performance processing section]
The performance processing unit 400 performs karaoke performance of 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 out the music data corresponding to the music ID from the storage unit 13 and performs the karaoke performance of the music. For music pieces that have been shortened by the shortening setting unit 300, the performance processing unit 400 performs a karaoke performance by shortening the performance time. Specifically, the performance time is shortened by executing functions such as 2-chorus fade-out and post-performance cut.

== About the operation of the karaoke apparatus 1 ==
Next, a specific example of the operation of the karaoke apparatus 1 in the present embodiment will be described with reference to FIG. FIG. 8 is a flowchart showing an operation example of the karaoke apparatus 1. In this example, an example will be described in which a new music is registered in the reservation queue during a karaoke performance of a music.

  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 expected waiting time calculation unit 200 is determined based on the performance start time of the currently played song and the reservation time of the song already registered in the reservation queue. The waiting time is obtained (calculation of the fixed waiting time. Step 11). Further, the expected waiting time calculation unit 200 calculates the remaining waiting time by calculating the remaining waiting time by adding the playing time of the currently played music and the playing time of the music already registered in the reservation queue. Step 12). Steps 11 and 12 may be performed in the reverse order or in parallel.

  The expected waiting time calculation unit 200 calculates the expected waiting time based on the determined waiting time calculated in step 11 and the remaining waiting time calculated in step 12 (calculation of the expected waiting time; step 13). The expected waiting time calculation unit 200 outputs the calculated expected waiting time to the shortening setting unit 300.

  The shortening setting unit 300 compares the singing waiting time with the expected waiting time calculated in step 13 (comparison between the singing waiting time and the expected waiting time. Step 14).

  If the expected waiting time is longer than the singing waiting time (in the case of Y in step 15), the shortening setting unit 300 has already placed in the currently played song or reservation queue so that the expected waiting time is less than or equal to the singing waiting time. Setting is made to shorten the performance time of the registered music (performance time shortening setting, step 16).

  The performance processing unit 400 performs karaoke performance of the music registered in the reservation queue (karaoke performance, step 17). At this time, if the expected waiting time is longer than the singing waiting time (in the case of Y in step 15), the performance processing unit 400 shortens the performance time for the music set to shorten the performance time in step 16. Perform karaoke performance. On the other hand, if the expected waiting time is shorter than the singing waiting time (N in step 15), the performance processing unit 400 performs the karaoke performance with the preset performance time.

  As described above, the karaoke apparatus 1 according to the present embodiment, every time a new music is registered in the reservation queue, the performance start time of the currently played music and the music already registered in the reservation queue. The estimated waiting time is calculated based on the reserved time, the remaining playing time of the performance time of the currently played music and the playing time of the music already registered in the reserved queue. If the expected waiting time is longer than the singing waiting time by comparing the part 200 with a preset singing waiting time and the expected waiting time, the music currently being played so that the expected waiting time is less than or equal to the singing waiting time And / or a shortening setting unit 300 for performing a setting for shortening the performance time of the music already registered in the reservation queue.

  With such a configuration, when it takes a long time to karaoke a reserved song, the expected waiting time can be made equal to or less than the singing waiting time by shortening the playing time of a reserved song or the like. it can. Therefore, according to the karaoke apparatus 1 according to the present embodiment, karaoke singing can be performed within a preset time even when there are many reserved music pieces. In this case, since the user who reserved the music does not have to wait for a long time before performing the karaoke singing, the user can enjoy the karaoke singing.

  Moreover, even if the performance time is set to be shortened for all the songs that can be shortened among the songs that are currently being played and the songs that are already registered in the reservation queue, the expected waiting time is the singing waiting time. If it becomes longer than this, the shortening setting unit 300 can notify the expected waiting time after setting the performance time to be shortened. According to such a karaoke apparatus 1, even if it is a case where karaoke singing cannot be performed within a singing waiting time, the user can grasp | ascertain the approximate time when the karaoke singing of the music which he reserved can be understood.

Second Embodiment
Next, with reference to FIGS. 9-12, the karaoke apparatus 1 which concerns on 2nd Embodiment is demonstrated.

  After making a reservation for a song, the reservation may be canceled for the convenience of the user. Here, after the shortening setting described in the first embodiment is performed, if cancellation of a reservation for a certain music is performed, all reserved music is within the singing waiting time without performing the shortening setting. Karaoke singing may be possible. In the present embodiment, an example will be described in which the shortening setting is canceled when the reservation of the music registered in the reservation queue is canceled. Detailed description of the same configuration as that of the first embodiment will be omitted.

(Software configuration)
FIG. 9 is a diagram showing a software configuration example of the karaoke main body 10 according to the present embodiment. The karaoke main body 10 includes a reservation registration unit 100, an expected waiting time calculation unit 200, a shortening setting unit 300, a performance processing unit 400, a first comparison unit 500, and a second comparison unit 600. In the reservation registration unit 100, the expected waiting time calculation unit 200, the shortening setting unit 300, the performance processing unit 400, the first comparison unit 500, and the second comparison unit 600, the CPU 11a executes a program stored in the memory 11b. Is realized.

[First comparison unit]
The first comparison unit 500 reserves the second music registered after the first music in a state where the first music for which the performance time has been shortened is registered in the reservation queue. Is canceled, the shortenable time of the first music is compared with the performance time of the second music.

  For example, in the example of FIG. 7, music C, music F, and music I are set to shorten the performance time. In this case, each of the music piece C, the music piece F, and the music piece I corresponds to a “first music piece”. Here, it is assumed that the reservation of the music K registered after the music C, the music F, and the music I is canceled. The music K in this case corresponds to “second music”. In order to cancel the reservation, the user selects a music piece whose reservation is to be canceled via the remote controller 50 or the like. The remote control device 50 transmits the song ID of the selected song to the karaoke main unit 10 in association with the reservation cancellation signal. The reservation registration unit 100 cancels the music by deleting the music corresponding to the music ID from the music registered in the reservation queue.

  In this case, for example, the first comparison unit 500, for example, the shortenable time (02 minutes 00 seconds) of the song C with the earliest reserved time among the shortened songs and the performance time of the song K (02 minutes 30 seconds). And compare. The first comparison unit 500 outputs the comparison result to the second comparison unit 600.

[Second comparison unit]
When the performance time of the second music is longer than the time for which the first music can be shortened, the second comparison unit 600 sets the shortening setting for the music reserved between the first music and the second music. Compare the expected waiting time when singing is canceled and the singing waiting time.

  For example, in the above example, when the performance time of music K (02 minutes 30 seconds) is compared with the shortenable time of music C set to be shortened (02 minutes 00 seconds), the performance time of music K is longer. .

  In this case, the second comparison unit 600 determines the expected waiting time when the shortening setting is canceled for each of the songs reserved between the songs C and K, that is, the songs D to J, and the song waiting time. And compare.

  Specifically, when the shortening setting of the music C is canceled, the remaining waiting time of the music D to the music J is increased by 2 minutes, respectively, and as a result, the expected waiting time is also increased by 2 minutes (see FIG. 10). Therefore, the second comparison unit 600 compares the expected waiting time of the music D to the music J when the shortening setting of the music C is canceled with the singing waiting time (30 minutes). The second comparison unit 600 outputs the comparison result to the shortening setting unit 300.

  In addition, the remaining waiting time (expected waiting time) of the music reserved before the music C, that is, the music B is not affected by the cancellation of the shortening setting of the music C or the cancellation of the reservation of the music K. The above comparison is not necessary. The remaining waiting time (expected waiting time) of the music reserved after the music K, that is, the music L is the comparison result output by the first comparison unit 500 (the performance time of the music K is shorter than the music C. Again, the above comparison is not necessary because it is not longer than 29 minutes 15 seconds.

[Speed setting section]
When the shortening setting unit 300 according to the present embodiment cancels the shortening setting for all the songs reserved between the first song and the second song, the waiting time is equal to or less than the singing waiting time. Cancel the shortening setting of the first music.

  For example, in the example of FIG. 10, the expected waiting times of the music D to the music J when the shortening setting is canceled are all equal to or shorter than the singing waiting time. In this case, the shortening setting unit 300 cancels the shortening setting of the music piece C (see FIG. 11).

  When there are a plurality of music pieces corresponding to the first music piece as in the example of FIG. 7, it is possible to determine whether or not the shortening setting can be released for the music piece F and the music piece I other than the music piece C for which the shortening setting has been released. Is possible.

  For example, an example in which it is determined whether or not the shortening setting of the music F can be canceled in the example of FIG. In this case, the first comparison unit 500 performs the performance time of the music piece K (02 minutes and 30 seconds) and the shortenable time of the music piece C and the music piece F that have been shortened (02 minutes 00 seconds + 01 minutes). 30 seconds = 03 minutes 30 seconds). In this case, the performance time of the music piece K is shorter than the possible reduction time. The first comparison unit 500 outputs a comparison result to that effect to the second comparison unit 600. In this case, the second comparison unit 600 does not perform subsequent processing.

  That is, if the performance time of the second music is shorter than the time that can be shortened for the first music (the time when the music can be shortened when there are a plurality of first music), the shortening setting unit 300 does not cancel the shortening setting.

  Similarly, the shortening setting unit 300 also applies to a part of the music reserved between the first music and the second music when the expected waiting time when the shortening setting is canceled exceeds the singing waiting time. , Do not cancel the shortened setting.

== About the operation of the karaoke apparatus 1 ==
Next, a specific example of the operation of the karaoke apparatus 1 in the present embodiment will be described with reference to FIG. FIG. 12 is a flowchart illustrating an operation example of the karaoke apparatus 1. In this example, it is assumed that the music V, the music W, the music X, the music Y, and the music Z are registered in the reservation queue in that order, and the music W is set to be shortened. Then, it is assumed that the user cancels the reservation of the music Y via the remote control device 50.

  In this case, the reservation registration unit 100 deletes the song Y selected by the user from the reservation queue (reservation cancellation, step 20).

  When the reservation is canceled, the first comparison unit 500 compares the performance time of the music Y with the shortenable time of the music W set to be shortened (compare the performance time with the shortenable time, step 21).

  When the performance time of the music Y is longer than the time that the music W can be shortened (in the case of Y in step 22), the second comparison unit 600 reserves the music reserved between the music W and the music Y that are set to be shortened. For X, the expected waiting time when the shortened setting is canceled is compared with the singing waiting time (the expected waiting time when the shortened setting is canceled is compared with the singing waiting time. Step 23).

  For the music X reserved between the shortened music W and the music Y, if the expected waiting time when canceling the shortening setting is equal to or shorter than the singing waiting time (in the case of Y in step 24), the speed setting unit 300 cancels the shortening setting of the music W that has been shortened (cancels the shortening setting. Step 25).

  As described above, the karaoke apparatus 1 according to the present embodiment is registered after the first music in a state where the first music for which the performance time is set to be shortened is registered in the reservation queue. When the reservation of the second music is canceled, the first comparison unit 500 that compares the shortenable time of the first music and the performance time of the second music, and the performance time of the second music Is longer than the shortenable time of the first music, the expected waiting time when the shortening setting is canceled and the singing waiting time for the music reserved between the first music and the second music. A second comparison unit 600 for comparison. And the shortening setting part 300 which concerns on this embodiment is the waiting time below a song waiting time when the shortening setting is cancelled | released about all the music reserved between the 1st music and the 2nd music. In this case, the shortening setting of the first music is canceled.

  Therefore, when the music reservation is canceled after performing the shortening setting, the performance time can be restored by canceling the shortening setting, and the karaoke singing time can be secured. Also, karaoke singing can be performed within a preset time for all the remaining reserved music pieces.
