In this case, what is emitted in the general karaoke room RM is the parent singing sound, the child singing sound of this karaoke room RM, and the karaoke performance sound. That is, the singing sound of the other karaoke room RM is not emitted. For this reason, the singer of the said karaoke room RM can enjoy a duet song without being confused by the singing sound of other general karaoke rooms RM.

  As can be seen from the above description, the slave side karaoke apparatus 2B (specifically, the set of the slave side karaoke main body 21B, the slave side first communication terminal 27B, the slave side power amplifier 29B, and the slave side speaker 22B) It corresponds to a reproducing means.

  Further, the child-side first communication terminal 27B (child-side signal transmission means) transmits the child-side microphone signal to the parent-side first communication terminal 27A. In addition, the child side 1st communication terminal 27 which other child side karaoke apparatuses 2C and 2D have similarly transmits a child side microphone signal to the parent side 1st communication terminal 27A. The parent-side first communication terminal 27A adjusts the input balance of each received child-side microphone signal according to the control signal from the parent-side karaoke main body 21A, and outputs it to the parent-side power amplifier 29A. Then, the parent power amplifier 29A amplifies the parent microphone signal, the performance sound signal, and the child microphone signal and outputs them to the parent speaker 22A. As a result, the karaoke performance sound, the parent microphone sound, and the child microphone sound are emitted from the parent speaker 22A.

  Here, the child microphone sound is emitted in a state where the volume balance is adjusted (a state where the volume is superior or inferior) based on the control signal from the parent karaoke main body 21A. Thereby, it becomes easy to hear a specific child side singing sound, and a duet singing can be easily performed. Specific control will be described later.

  As can be seen from the above description, the parent-side karaoke apparatus 2A (specifically, a set of the parent-side karaoke main body 21A, the parent-side first communication terminal 27A, the parent-side power amplifier 29A, and the parent-side speaker 22A) It corresponds to a reproducing means.

  Next, the video signal will be described. The parent-side video signal generated by the parent-side microphone-equipped camera 25A is input to the parent-side second communication terminal 28A. Similarly, the child-side video signal generated by the child-side microphone-equipped camera 25B or the like is input to each child-side second communication terminal 28B or the like. Then, the parent-side second communication terminal 28A transmits the parent-side video signal to each child-side second communication terminal 28B or the like, and each child-side second communication terminal 28B or the like transmits the child-side video signal to the parent-side second communication. Transmit to terminal 28A. Furthermore, the parent-side second communication terminal 28A outputs the parent-side video signal and each child-side video signal to the parent-side karaoke main body 21A, and each child-side second communication terminal 28B etc. The side video signal is output to the child side karaoke main body 21B or the like.

  The parent-side karaoke main body 21A combines each child-side video signal with a video signal for one screen, combines the lyrics telop, and outputs it to the parent-side monitor 23A. Thereby, the image | video of the child side singer who sings in each general karaoke room RM is displayed on the parent side monitor 23A. On the other hand, each child side karaoke main body 21B, etc. synthesizes the parent side video signal and its own child side video signal into a video signal for one screen, synthesizes a lyrics telop, and outputs it to each child side monitor 23B. Thereby, the video of the parent singer and the video of itself are displayed on each child monitor 23B and the like. As a result, a communication duet can be realized between the super VIP room and each general karaoke room RM.

  Next, the flow of processing when performing a communication duet will be described with reference to the flowchart of FIG. In this flowchart, steps S11 to S20 are processes of the parent karaoke apparatus 2A, steps S31 to S40 are processes of the child karaoke apparatuses 2B to 2D, and steps S51 to S55 are processes of the host apparatus 1. In addition, since each child side karaoke apparatus 2B-2D is equivalent, it demonstrates collectively.

  In this communication karaoke system, first, the user of the super VIP room or the user of the general karaoke room RM logs in through the parent side karaoke device 2A and the child side karaoke devices 2B to 2D (S11, S31). Thereby, the user ID for identifying each user and the device ID for identifying each karaoke device 2A to 2D are transmitted to the host device 1. The host device 1 receives the user ID and the device ID and stores them in a state of being associated with each other (S51).

  The parent side karaoke device 2A and the child side karaoke devices 2B to 2D monitor whether or not the communication duet has been selected (S12, S32), and if selected, the music ID indicating the target song of the communication duet, The user ID and device ID are transmitted to the host device 1 (S13, S33). When the host device 1 receives the song ID or the like (S52), the host device 1 recognizes the user who performs the duet song, the karaoke devices 2A to 2D, and the karaoke song based on the song ID, the user ID, and the device ID, and is common. Duet GrID is set (S53).

  Along with the selection of the communication duet, the parent side karaoke device 2A and the child side karaoke devices 2B to 2D are communicably connected via the first dedicated transmission path 4B and the second dedicated transmission path 4C (S14, S34). For example, the first dedicated transmission line 4B is connected by making a call from the parent first communication terminal 27A and receiving and off-hooking at the child first communication terminal 27B. Similarly, the second dedicated transmission line 4C is connected by making a call from the parent-side second communication terminal 28A, and receiving and off-hooking at the child-side second communication terminal 28B. In addition, you may call and connect to each parent side karaoke apparatus 2A from each child side karaoke apparatus 2B-2D.

  If the dedicated transmission lines 4B and 4C are connected, sound / video adjustment processing (S15, S35) is performed. In this process, for example, the user adjusts the microphone volume on the room side and the partner side, or performs echo adjustment. In addition, the camera angle, room brightness, and the like are also adjusted.

  When the sound / video adjustment process is completed, it is determined that the communication duet is ready, and a start signal is transmitted from the parent karaoke device 2A (S16), and each child karaoke device 2B to 2D receives the start signal (S36). . Then, the parent side karaoke device 2A transmits the mixed parent side microphone signal and the performance signal to each child side karaoke device 2B to 2D, and each child side karaoke device 2B to 2D receives the child side microphone signal. Duet transmission is started by transmitting to the side karaoke apparatus 2A (S17, S37). During the duet singing, in the super VIP room, duet karaoke main body 21A performs duet partner selection processing (S18). On the other hand, in the general karaoke room RM, as described above, duet singing is performed using the parent-side singing sound, the child-side singing sound of the karaoke room RM, and the karaoke performance sound (S38).

  During the duet singing period, each of the karaoke devices 2A to 2D converts the microphone signal of each karaoke room RM to generate singing voice data, and sequentially stores them in the singing voice data storage area of the main body side storage unit 33. Similarly, the video signal of each karaoke room RM is converted to generate singing video data, and sequentially stored in the singing video data storage area of the main body side storage unit 33.

  Here, selection of a duet partner in the super VIP room will be described. During the duet singing period, the child-side microphone signals from the child-side karaoke devices 2B to 2D are input to the parent-side karaoke device 2A. Here, if each child side microphone signal is mixed and reproduced at the same volume, the sound is mixed in a shifted state due to the difference in transmission delay of each general karaoke room RM or the way of singing for each singer, etc. It is difficult to sing and there is a risk that interest will be impaired.

  Therefore, in this system, in the super VIP room, each child side microphone signal is selected while being switched as appropriate, and only the selected child side microphone signal is reproduced, or the reproduction volume other than the selected child side microphone signal is selected. The playback volume of the side microphone signal is sufficiently low. As described above, the parent-side karaoke apparatus 2A has a plurality of parent-side first communication terminals 27A, each of which can be controlled by a control signal from the parent-side karaoke main body 21A. For example, when only the selected child microphone signal is reproduced, only the selected child microphone signal is fetched into the parent karaoke main body 21A, and the other child microphone signals are not fetched.

  In the example shown in FIG. 11A, the child microphone signal transmitted from the child karaoke device 2B is taken into the parent karaoke main body 21A, and the child microphone signals from the other child karaoke devices 2C and 2D are used. Not taken in. For this reason, in a super VIP room, a communication duet is performed with the singer of the child side karaoke apparatus 2B. Here, a parent microphone signal and a performance sound signal are transmitted to each of the child karaoke apparatuses 2B to 2D. For this reason, in the general karaoke room RM where each child side karaoke apparatus 2B-2D is installed, a communication duet is performed with the singer of the parent side base.

  Similarly, in the example shown in FIG. 11B, a communication duet is performed with the singer of the child karaoke apparatus 2C in the super VIP room, and in the example shown in FIG. 11C, the child side is executed in the super VIP room. A communication duet is performed with the singer of the karaoke apparatus 2D.

  In this example, the singer in the super VIP room performs a communication duet with only the singer in the selected general karaoke room RM, so that the child-side singing sound can be easily heard and the communication duet can be performed in a good manner.

  In the example of FIG. 11, the case where only the selected child side microphone signal is taken into the parent side karaoke main body 21A has been described as an example, but all the child side microphone signals are taken into the parent side karaoke main body 21A, The child microphone signal other than the microphone signal may be reproduced with a volume sufficiently smaller than the selected child microphone signal. If comprised in this way, the singing sound of the selected child side singer will be reproduced | regenerated with a relatively large sound volume compared with the singing sound of another child side singer. That is, since the singing sound of the other general karaoke room RM is reproduced even though the volume is low, it can be sung with other child-side singers or can be sung with a three-dimensional effect.

  Next, duet partner switching processing in the Super VIP room will be described. As shown in FIG. 12, in this system, the skill of singing performed in each karaoke room RM is performed for each of a plurality of sections constituting a certain karaoke piece of music, and the karaoke main body 21 (parent side scoring means, child side scoring means). Will be scored. Therefore, the parent karaoke apparatus 2A (parent reproduction means) selects a duet partner of the section based on the scoring result of the immediately preceding section, and prioritizes the child microphone signal of the selected partner over other child microphone signals. You are playing.

  For example, the duet partner in the section PT2 is the singer of the child side karaoke apparatus 2D that has acquired the highest score in the immediately preceding section PT1, and the duet partner in the section PT3 is the child side that has acquired the highest score in the immediately preceding section PT2. It becomes a singer of the karaoke apparatus 2C. For this reason, the child side karaoke main body 21 of each general karaoke room RM scores the skill of the song performed in the said karaoke room RM for every some area which comprises one karaoke music. Moreover, every time the scoring of a certain section is completed, the child-side karaoke main body 21 (child-side scoring result transmitting means) transmits the scoring result of the section to the parent-side karaoke apparatus 2A.

  In addition, the scoring result is not obtained in the first section PT1. Therefore, zapping is performed in this section PT1. That is, the singer is selected while switching at predetermined time intervals.

  When such control is performed, the parent singer can perform a communication duet in turn with each child singer in the section PT1 by zapping. After the section PT2, a communication duet can be performed with a singer with a good scoring result. That is, the parent singer can perform communication duets with many child singers in the early stage, and thereafter, can perform communication duets with skillful child singers. On the other hand, the higher the scoring result, the more appealing to the parent singer, the more incentive to sing well.

  Although the example which selects a duet partner automatically was demonstrated above, you may make a singer (parent singer) of a Super VIP room select a duet partner. In the example shown in FIG. 13A, the parent monitor 23A is divided into four display areas 23a to 23d, and images of three singers (child singers) are displayed in the display areas 23a to 23c. Is displayed. And the singer of the display area 23a is selected by operation of the parent-side remote control device 26A. Accordingly, as shown in FIG. 13 (b), the child monitor 23 used by the selected child singer displays the image of the parent singer and the image of the child singer in the display area 23e. , 23f, and a message indicating that the parent singer is being selected is displayed in the display area 23g.

  In this process, as shown in FIGS. 11A to 11C, the selected karaoke room indicates that the parent side karaoke apparatus 2A (selected signal transmission means) is selecting a selected karaoke room. Transmitting to RM (any of the child side karaoke devices 2B to 2D), and the child side karaoke devices 2B to 2D (child side notification means) receiving the selected signal, send a message based on the selected signal. This is realized by generating and displaying on the child monitor 23B or the like.

  Returning to FIG. 10, when the duet singing is completed (S19, S39), each of the karaoke apparatuses 2A to 2D transmits the singing voice data and the singing video data generated during the duet singing together with the scoring data to the host apparatus 1 (S20). , S40). The host device 1 receives each data (S54) and stores it in the corresponding storage area of the host-side storage area in association with the duet GrID.

  Next, the host device 1 (moving image data generating means) generates duet song browsing moving image data (duet moving image data) based on the received singing voice data and singing image data (S55). In the present embodiment, a plurality of child video data (singing) acquired in each of a plurality of general karaoke rooms RM with respect to the parent video data (a set of singing voice data and singing video data) acquired in the super VIP room. The video data for browsing is generated by selecting and synthesizing a set of audio data and singing video data. For example, the host device 1 selects, for each section, the child-side moving image data of the section with the best scoring result based on the scoring results for each section with respect to the child-side moving image data, and synthesizes the parent-side moving image data. The generated moving image data for browsing is published by the host device 1 so as to be viewable from the user terminal 3.

  As described above, in this system, the child karaoke apparatuses 2B to 2D reproduce the singing sound (parent microphone sound) of the super VIP room and do not reproduce the singing sound from the other general karaoke rooms RM. Thereby, a duet with the singer of the super VIP room can be performed with good mood. Moreover, 2A of parent | side karaoke apparatuses select and reproduce | regenerate one from the received song sound of each general karaoke room RM so that switching is possible. For example, only the singing sound of the selected general karaoke room RM is reproduced, or the singing sounds of other general karaoke rooms RM are reproduced with a sufficiently small volume. Thereby, it becomes easy to hear the selected child-side singing sound, and a duet singing in the super VIP room is facilitated.

  In this system, a mixed signal of a performance sound signal and a parent microphone signal is transmitted from the parent side karaoke device 2A to the plurality of child side karaoke devices 2B to 2D, and the child side karaoke devices 2B to 2D transmit a performance sound signal. And playing back the parent microphone signal. Thereby, in the general karaoke room RM, duet singing can be performed according to the karaoke performance sound and the parental singing sound at the parental base where the time axis is aligned.

  In this system, the skill of singing performed in the general karaoke room RM is scored for each of a plurality of sections constituting one karaoke piece. Then, based on the scoring result, it is determined whether or not the reproduction is performed at the parent site. Thereby, the incentive to sing well can be given to the singer in the general karaoke room RM. Furthermore, in general karaoke room RM, since it is informing that it is being selected in the super VIP room, this incentive can be given more strongly.

  Further, in this system, due to the parent video data acquired in the super VIP room, a plurality of child video data acquired in each of the plurality of general karaoke rooms RM are selected and combined, thereby allowing duet video data. Is generated. Thereby, duet video data in which the singing video and the singing voice of the general karaoke room RM are switched with respect to the singing video and the singing voice of the super VIP room are generated. As a result, it is possible to generate duet video data with enhanced interest. Furthermore, since the child-side moving image data is selected and synthesized according to the scoring results for each section, it is possible to give an incentive to improve the singing ability to the singers in each general karaoke room RM.
