  In this way, in order to enjoy the singing by simultaneously performing duet songs etc. on separate karaoke performance terminals, the performance start timing at each karaoke performance terminal is set so that the users of each karaoke performance terminal do not feel uncomfortable. It is necessary to approximately match. Furthermore, in each karaoke performance terminal, the music selection reservation is made separately, and when a plurality of karaoke music selection reservations are already made, it is necessary to adjust the performance order of duet music etc. in each karaoke performance terminal. is there.

  For example, when performing duet (network chorus) at two karaoke performance terminals, it is assumed that one karaoke performance terminal has already reserved 5 songs and the other karaoke performance terminal has already reserved 3 songs. In this case, waiting for the performance of the five songs already reserved in one karaoke performance terminal to end, and in both karaoke performance terminals, the duet (network chorus) is started. Nothing can be done for the performance time of about 2 songs, which is the difference in the number of reserved songs. Therefore, it is necessary to adjust the timing for starting a duet (network chorus) so that both karaoke performance terminals do not give the user an unpleasant feeling or frustration.

  The present invention has been proposed in view of the above-described circumstances. When performing network chorus in a karaoke system in which a plurality of karaoke performance terminals are connected to a network, reservation of karaoke music for performing network chorus at each karaoke performance terminal is performed. It is an object of the present invention to provide a performance start synchronization system in network chorus that can efficiently perform network chorus by adjusting the order.

  The performance start synchronization system in network chorus according to the present invention has been proposed to achieve the above-described object, and has the following features. That is, the performance start synchronization system in network chorus according to the present invention simultaneously plays the same karaoke music piece at a plurality of karaoke performance terminals connected to the network, and the singing voice inputted at each karaoke performance terminal is played into other karaoke performances. It has a function of transmitting to a terminal and performing network chorus, and is capable of adjusting the reservation order of karaoke songs in each karaoke performance terminal, and is a system for starting performance of karaoke songs at the same time, reservation management means, A reserved music notification means, a chorus designation music reservation order adjustment means, a chorus mode transition means, a chorus mode transition notification means, and a performance start instruction permission means are provided.

  Each means is a means provided in each karaoke performance terminal. The reservation management means is a means for registering and managing at least the music identification information of the karaoke music in the reservation queue when the user gives an instruction to select an arbitrary karaoke music. The reserved music notification means, when the karaoke music for which the music selection instruction has been performed is a karaoke music (network choral music) for performing network chorus, the music identification information of each karaoke music managed by the reservation management means and its registration It is means for notifying the order to other karaoke performance terminals performing network chorus. In addition, you may include the remaining performance time of the karaoke music piece currently played in the information notified to the other karaoke performance terminal which performs network chorus.

  The chorus-designated music reservation order adjusting means, when registering karaoke music (network choral music) for network chorusing in the reservation management means in the reservation queue, each reserved music managed by its own reservation management means. Based on the reservation order and its performance time, and the reservation order and performance time of each reserved music notified from other karaoke performance terminals, each sum obtained by sequentially adding the performance time of each reserved music on its own karaoke performance terminal Karaoke music (network chorus) that performs network chorusing next to reserved music in which the difference between the performance time and the total performance time obtained by sequentially adding the performance times of each reserved music at other karaoke performance terminals is equal to or less than a predetermined reference value (Music) is a means for registering.

  At this time, the remaining performance time of the karaoke song currently being played is set as the performance time of the karaoke song, and the karaoke song is regarded as the head of each reserved song managed by the reservation management means, and the network chorus is performed. You may adjust the reservation order of the karaoke music to perform.

  The chorus mode transition means waits for a performance start instruction when a karaoke song (network choral song) for network chorus is at the head of the reservation queue, and shifts to a chorus mode for starting the performance of the karaoke song. Means. The chorus mode transition notification means is a means for notifying the transition to the chorus mode by transmitting a chorus mode transition signal to other karaoke performance terminals performing network chorus when the chorus mode transition is performed.

  The performance start instruction permission means permits transmission of a performance start instruction signal for karaoke music (network choral music) for network chorusing after detecting that all karaoke performance terminals performing network chorus have transmitted a chorus mode transition signal. It is a means to do.

  In the performance start synchronization system in network chorus having such a configuration, in order to identify each karaoke performance terminal in advance by agreeing to perform network choral among users of a plurality of karaoke performance terminals connected to the network. The function for performing the network chorus realized by the present invention on the premise that the music identification information for identifying the network choral music is also agreed. Use.

  In addition, the karaoke music selection reservation is performed using a karaoke remote control device, and each karaoke performance terminal is paired with a karaoke remote control device for performing a music selection reservation. Further, each karaoke performance terminal and each karaoke remote control device can communicate with other karaoke performance terminals or karaoke remote control devices via a communication network, and can transmit / receive various data to / from these devices.

  In the performance start synchronization system in the network chorus of the present invention, for example, a music selection reservation is performed using a karaoke remote control device paired with each karaoke performance terminal. In addition, using a function for performing network chorusing, data exchange is performed in advance between karaoke performance terminals connected via a communication network to recognize a karaoke performance terminal (for example, a performance terminal ID) that performs network chorusing. . Furthermore, data exchange is also performed at each karaoke performance terminal for music identification information (for example, music ID) for identifying network choral music.

  In each karaoke performance terminal that performs network chorus, the reserved music is managed in the reserved queue by the function of the reservation managing means. At this time, at least the music identification information of the reserved music is arranged in the reserved order and the reserved queue is generated. . The performance time of each reserved music can be obtained by referring to the music database based on the music identification information, for example, but in the reservation queue, the karaoke music specified by the music identification information in the music identification information The performance time may be associated and managed.

  Then, when the karaoke music for which the music selection instruction has been performed is a network choral music by the function of the reserved music notification means, the music identification information of each karaoke music managed by the reservation management means and the registration order thereof are Notify other karaoke performance terminals performing chorus. Thereby, in each karaoke performance terminal which performs network chorus, the reservation order of the reservation music in another karaoke performance terminal can be acquired. As described above, the performance time of each reserved music can be acquired by referring to the music database based on the music identification information, for example. Further, the remaining notification time of the currently played karaoke song may be included in the information notified by the function of the reserved song notification means.

  And in each karaoke performance terminal which performs network chorus, a reservation order is adjusted when registering a network chorus music in a reservation queue by the function of a chord designation | designated music reservation order adjustment means.

  That is, based on the reservation order and performance time of each reserved music managed by its own reservation management means, and the reservation order and performance time of each reserved music notified from other karaoke performance terminals The arithmetic processing is performed. The difference between each total performance time obtained by sequentially adding the performance times of each reserved song at its own karaoke performance terminal and each total performance time obtained by sequentially adding the performance times of each reserved music at the other karaoke performance terminals is a predetermined value. Next to the reserved music that is below the reference value, the network chorus music is registered (interrupt reservation). At this time, in each karaoke performance terminal, the total performance time may be obtained in consideration of the remaining performance time of the reserved music currently being played.

  For example, the performance times of the reserved music registered in the reservation queue are sequentially added in descending order from the top side, and the total performance time at the own karaoke performance terminal and the total performance time at the other karaoke performance terminals are calculated. When the difference is equal to or less than a predetermined time (for example, 30 seconds or less), the network choral music is reserved for interruption next to the reserved music to which the performance time is added last. In addition, the performance time of all reserved songs at each karaoke performance terminal is added sequentially, and the reservation between the total performance time at one's own karaoke performance terminal and the total performance time at other karaoke performance terminals is minimized. Next to music, network choral music may be reserved for interruption.

  Since the calculation described above is performed using the same algorithm in each karaoke performance terminal, each karaoke performance terminal registers the network choral music in the reservation queue so that the performance waiting time is substantially the same. Can be managed.

  Then, when the network chorus music is at the head of the reservation queue at each karaoke performance terminal, the chorus mode transition means shifts to the chorus mode (single music mode). Note that the chorus mode (unipolar mode) is a mode in which the performance of the karaoke music is started on the condition that a predetermined performance start instruction is given without automatically starting the performance of the karaoke music.

  Thereafter, the function of the chorus mode transition notification means transmits a chorus mode transition signal to other karaoke performance terminals performing network chorus to notify that the transition to the chorus mode has been made. In each karaoke performance terminal that has shifted to the chorus mode (single music mode), the function of the performance start instruction permission means detects that all karaoke performance terminals that perform network chorus have transmitted performance end signals, The transmission of the performance start instruction signal is permitted.

  In this case, the karaoke performance terminal having the initiative to start the performance may be any karaoke performance terminal that performs network chorusing. For example, the karaoke performance terminal that is set in advance as the main karaoke performance terminal (with the initiative) A performance terminal can be determined in advance.

  When the transmission of the performance start instruction signal is permitted and the performance start signal is transmitted, the performance of the network choral music starts simultaneously in all the karaoke performance terminals performing the network chorus.

  According to the performance start synchronization system in the network chorus of the present invention, when registering the network chorus music in the reservation queue, the reservation order and performance time of the reserved music already registered in the reservation queue in each karaoke performance terminal. Based on this, the reservation order is determined so that the difference in performance waiting time is reduced in all karaoke performance terminals performing network chorus.

  Therefore, in each karaoke performance terminal, the difference in waiting time until the network chorus music is played is reduced, and there is no unfairness in waiting time between karaoke performance terminals performing network chorus. In addition, since the reservation order of the network choral music is appropriate, it is possible to further enhance the enjoyment of the network chorus without giving the user unpleasantness and frustration.

<Synchronization procedure of network chorus music reservation order adjustment and performance start>
With reference to FIG. 2 to FIG. 5, a description will be given of karaoke song reservation and performance start synchronization procedures in the performance start synchronization system 10 of the present embodiment. In the following description, it is assumed that a network chorus agreement has been established in the karaoke performance terminal 30 connected to the network. In addition, it is assumed that the karaoke performance terminals 30 performing network choral among users recognize each other's performance terminal information (for example, performance terminal ID) in advance.

  As shown in FIG. 2, in the karaoke remote control device (1) paired with the karaoke performance terminal (1), when karaoke music (network choral music) for network chorus is selected, the karaoke performance terminal (1) is selected. ) And the karaoke performance terminal (2), the music selection reservation information is transmitted (S1).

  When the karaoke performance terminal (1) receives the song selection reservation information (S2), the karaoke performance terminal (1) is currently registered in the reservation queue from the karaoke performance terminal (1) to the karaoke performance terminal (2). The reservation order of reserved music is transmitted (S4). At this time, the information to be transmitted may include the remaining performance time of the currently played karaoke song. In the karaoke performance terminal (2), when the reservation order of the reserved music is received from the karaoke performance terminal (1), it is stored in the RAM or the like together with the performance time of each reserved music (S5).

  Similarly, when the karaoke performance terminal (2) receives the music selection reservation information from the karaoke remote control device (1) (S3), the karaoke performance terminal (1) is notified of the reservation tune currently registered in the reservation queue. The reservation order is transmitted (S6). In the karaoke performance terminal (1), when the reservation order of the reserved music is received from the karaoke performance terminal (2), it is stored in the RAM together with the performance time of each reserved music (S7). Note that either step 4 (S4) and step 5 (S5) and step 6 (S6) and step 7 (S7) may be performed first or may be parallel processing.

  The karaoke performance terminal (1) and the karaoke performance terminal (2) each receive the reservation order of reserved songs and acquire the performance time of each reserved song. The reservation order of the choral music is adjusted and registered in the reservation queue (interrupt reservation) (S8, S9).

  Various algorithms can be used for the calculation for adjusting the reservation order of the network choral music by the chorus designated music reservation order adjusting means 68. For example, the network choral music may be reserved for interruption after the reserved music in which the difference between the total performance times obtained by sequentially adding the performance times of each reserved music is first below the reference value, or the performance of all reserved music The total performance time may be calculated by sequentially adding time, and the network choral music may be reserved for interruption next to the reserved music that minimizes the difference in the total performance time.

  First, an algorithm for interrupt reservation of a network chorus music next to a reserved music in which the difference in total performance time obtained by sequentially adding the performance times of each reserved music first becomes equal to or less than a reference value will be described. In addition, since the algorithm of the reservation order adjustment of the network chorus music in the karaoke performance terminal (1) and the reservation order adjustment of the network chorus music in the karaoke performance terminal (2) are the same, the karaoke performance terminal (1) and the karaoke performance terminal (1) In the performance terminal (2), arithmetic processing is performed in the same procedure.

  As shown in FIG. 4, the performance time (255 seconds) of the music (a1) that is first registered in the reservation queue of the karaoke performance terminal (1) and the reservation queue of the karaoke performance terminal (2). Then, the performance time (185 seconds) of the music (b1) registered and registered first is compared. In this example, the difference in performance time between the music (a1) and the music (b1) is 70 seconds. In this embodiment, since the reference value for permitting interrupt reservation of network chorus music is set to 30 seconds or less, the network chorus music is interrupted at the second rank of music (a1) and music (b1). It cannot be reserved.

  Subsequently, the performance time (255 seconds) of the music (a1) that is first registered in the reservation queue of the karaoke performance terminal (1) and the first in the reservation queue of the karaoke performance terminal (2). Is compared with the total value (345 seconds) of the performance time (185 seconds) of the music (b1) reserved and registered in (2) and the performance time (160 seconds) of the music (b2) registered second.

  In this case, the performance time of the reserved music (a1) registered in the reservation queue of the karaoke performance terminal (1) and the reserved music (b1 and b) registered in the reservation queue of the karaoke performance terminal (2). The difference in the total value (total) of the performance times of b2) is 90 seconds, which exceeds the reference value of 30 seconds, so that the rank (second) of the music (a1) and the music (b1 and b2) It is not possible to make interrupt reservations for network choral music in the second rank (third).

  Subsequently, the performance time (255 seconds) of the music (a1) first reserved and registered in the reservation queue of the karaoke performance terminal (1) and the performance of the music (a2) second reserved and registered. The total value (500 seconds) of the time (245 seconds), the performance time (185 seconds) of the music (b1) first registered in the reservation queue of the karaoke performance terminal (2), and the second The total value (345 seconds) of the performance time (160 seconds) of the music (b2) registered for reservation is compared.

  In this case, the total value (sum) of the performance times of the reserved songs (a1 and a2) registered in the reservation queue of the karaoke performance terminal (1) and the reservation time queue of the karaoke performance terminal (2) are registered. The difference in the total value (total) of the performance times of the reserved songs (b1 and b2) being 155 is 155 seconds and exceeds the reference value of 30 seconds, so the songs (a1 and a2) and the songs (b1 and b2) It is not possible to make an interrupt reservation for each of the network choral music pieces in the second order (b3) of b2).

  Subsequently, the performance time (255 seconds) of the music (a1) first reserved and registered in the reservation queue of the karaoke performance terminal (1) and the performance of the music (a2) second reserved and registered. The total value (500 seconds) of time (245 seconds) and the performance time (185 seconds) of the music (b1) reserved and registered first in the reservation queue of the karaoke performance terminal (2), second The performance time (160 seconds) of the music (b2) registered for reservation and the total value (485 seconds) of the performance time (140 seconds) of the music (b3) reserved and registered for the third time are compared.

  In this case, the total value (sum) of the performance times of the reserved songs (a1 and a2) registered in the reservation queue of the karaoke performance terminal (1) and the reservation time queue of the karaoke performance terminal (2) are registered. The difference in the total value (total) of the performance times of the reserved music pieces (b1, b2, and b3) being set is 15 seconds, which is within the standard value of 30 seconds.

  Therefore, in the karaoke performance terminal (1), the network chorus tune (N1) is reserved for interruption in the subsequent rank (third) of the tunes (a1 and a2), and in the karaoke performance terminal (2), the tunes (b1, b2 and b3) The network chorus music (N1) is reserved for interruption at the subsequent rank (fourth).

  Next, a description will be given of an algorithm for calculating the total performance time by sequentially adding the performance times of all the reserved music pieces, and interrupting reservation of the network choral music next to the reserved music piece that minimizes the difference in the total performance time. . As described above, the algorithm for the reservation order adjustment of the network chorus music in the karaoke performance terminal (1) and the algorithm for the reservation order adjustment of the network chorus music in the karaoke performance terminal (2) are the same. ) And the karaoke performance terminal (2) perform arithmetic processing in the same procedure.

  As shown in FIG. 5, in the reservation queue of the karaoke performance terminal (1), the performance time (255 seconds) of the music (a1) registered and registered first is acquired. Subsequently, the performance time (255 seconds) of the music (a1) first reserved and registered in the reservation queue of the karaoke performance terminal (1) and the performance of the music (a2) second reserved and registered. The total value (500 seconds) of time (245 seconds) is calculated. Then, the performance time of the music (a1), the performance time of the music (a2), the total value (715 seconds) of the performance time of the music (a3), the performance time of the music (a1), and the performance of the music (a2). The total value (875 seconds) of the time, the performance time of the music (a3), and the performance time of the music (a4) is calculated.

  On the other hand, in the reservation queue of the karaoke performance terminal (2), the performance time (185 seconds) of the music (b1) registered and registered first is acquired. Subsequently, the performance time (185 seconds) of the music (b1) first reserved and registered in the reservation queue of the karaoke performance terminal (2) and the performance of the music (b2) second reserved and registered. The total value (345 seconds) of the time (160 seconds) is calculated. Then, the performance time of the music (b1), the performance time of the music (b2), the total value (485 seconds) of the performance time of the music (b3), the performance time of the music (b1), and the performance of the music (b2). The total value (710 seconds) of the time, the performance time of the music (b3), and the performance time of the music (b4) is calculated.

  As described above, the performance times of all the reserved music pieces are sequentially added to calculate each total performance time, and the reserved music whose difference in the total performance times is the minimum value is selected. In the example described above, the minimum value of the difference in the total performance time is (715 seconds−710 seconds = 5 seconds), and the reserved music that minimizes the difference in the total performance time is the music ( a3), and in the karaoke performance terminal (2), it is the music (b4). Therefore, in the karaoke performance terminal (1), the network chorus music (N1) is reserved for interruption in the subsequent rank (fourth) of the music (a3), and in the karaoke performance terminal (2), the lower rank ( (5th) makes an interrupt reservation for the network chorus music (N1).

  Note that the algorithm for the reservation order adjustment is not limited to the one described above, and the network chorus music is registered next to the reserved music in which the difference in the total performance time of the reserved music at each karaoke performance terminal is equal to or less than a predetermined reference value. Any algorithm may be used as long as it is possible.

  Next, a case will be described as an example where the karaoke performance terminal (2) first shifts to the chorus mode (single music mode) and then the karaoke performance terminal (1) shifts to the chorus mode (single music mode). Note that the order of karaoke performance terminals that shift to the chorus mode (single music mode) is determined based on the reservation order and performance time of karaoke songs already reserved and registered in each karaoke performance terminal. It is not restricted to the example shown in.

  As shown in FIG. 3, in the karaoke performance terminal (2), when the performance of the reserved music advances and the network chorus music becomes the head of the reservation queue (S12), the karaoke performance terminal (2) is in the chorus mode (single music mode). (S13). And if a karaoke performance terminal (2) transfers to a chorus mode (single music mode), a chorus mode transfer signal will be transmitted with respect to a karaoke performance terminal (1) from a karaoke performance terminal (2) (S14). When the karaoke performance terminal (1) receives the chorus mode transition signal from the karaoke performance terminal (2), it stores that the karaoke performance terminal (2) has shifted to the chorus mode (S15).

  Similarly, in the karaoke performance terminal (1), when the performance of the reserved music advances and the network chorus music becomes the head of the reservation queue (S16), the karaoke performance terminal (1) shifts to the chorus mode (single music mode). (S17). When the karaoke performance terminal (1) shifts to the chorus mode (single music mode), the karaoke performance terminal (1) transmits a chorus mode shift signal to the karaoke performance terminal (2) (S18). When the karaoke performance terminal (2) receives the chorus mode transition signal from the karaoke performance terminal (1), it stores that the karaoke performance terminal (1) has shifted to the chorus mode (S19).

  In this state, the karaoke performance terminal (1) and the karaoke performance terminal (2) have detected that all karaoke performance terminals performing network chorus have transmitted performance end signals, and each transmits a performance start signal. Is permitted (S20, S21). When a performance start signal is transmitted from the karaoke remote control device (1) paired with the karaoke performance terminal (1) (S22), the karaoke performance terminal (1) and the karaoke performance terminal ( In 2), the performance of the network chorus starts simultaneously (S23, S24).

  In the example shown in FIGS. 2 and 3, the karaoke performance terminal (1) has the initiative to reserve the music selection and start the performance, but the karaoke performance terminal (2) has the initiative to reserve the music selection and start the performance. It may be. Further, either the karaoke performance terminal (1) or the karaoke performance terminal (2) may have a configuration reservation initiative and the other may have a performance start initiative. Furthermore, even when there are three or more karaoke performance terminals 30 performing network chorusing, performance start can be synchronized by the same procedure as described above.
