The channel selection means provided in the output terminal device selects one channel from the multi-channels according to the notification from the channel notification means.

Since a channel is assigned to each information providing device, external output can be independently obtained by the same number of output terminal devices as the information providing devices. When the information providing device is the karaoke playing device and the output terminal device is the karaoke terminal device as described in claim 3, karaoke can be simultaneously enjoyed by the same number of karaoke terminal devices as the karaoke playing device. Further, even if there is a karaoke terminal device that waits for the karaoke playing device to be available, it is sufficient to wait for one of the plurality of karaoke playing devices to finish playing, so that the waiting time can be shortened.

In the information communication system according to claim 3, the storage means stores the karaoke piece data as the common data, and in the karaoke performance apparatus as the information providing apparatus, the information processing means stores the karaoke pieces in the storage means. Use the song data to create karaoke performance information. In addition,
This karaoke performance information corresponds to the external output information described in claim 1.

In the karaoke terminal device as the output terminal device, the command sending means sends the music command input through the input means, and the information output means outputs the karaoke performance information by voice. In the karaoke central control device as the central control device, when the command acquisition means acquires the music command, the instruction means instructs the karaoke performance device to create karaoke performance information of the music corresponding to the music command.

For this reason, for example, in accommodation facilities such as hotels and restaurants having a large number of private rooms, karaoke terminal devices are installed in each room, and a central control device and karaoke performance device are installed in, for example, a management room. Then you can enjoy karaoke in each room. At this time, all of the installed karaoke terminal devices do not simultaneously send the music command, and a karaoke playing device that is less than the karaoke terminal devices can be sufficiently used. Therefore, it is possible to enjoy karaoke in each room without installing the karaoke playing device and the karaoke terminal device in a one-to-one relationship, which is also excellent in cost effectiveness.

A flowchart of interrupt processing executed by the PU 91,
FIG. 7 is a flow chart of processing executed by the CPU 52 of the karaoke playing device 5, and FIG.
It is an explanatory view of the structure of the cue table stored in the AM 93, but the processes executed by the central control device 9, the karaoke playing device 5, and the karaoke terminal device 19 are closely related to each other, and therefore, in the following description, any time. Refer to these figures.

First, the explanation will be started from the processing in the karaoke terminal device 19. As shown in FIG. 4, the terminal control device 21 of the karaoke terminal device 19 waits for a request to be input by operating the operation panel 24 or the remote controller 25 (S101), and if there is a request input (YES in S101), The requested song number is transmitted to the central controller 9 (S102).

The CPU 91 of the central controller 9 normally executes the processing of the main routine shown in FIG. 5, but if there is communication from the karaoke terminal device 19 as described above, this is caused. And executes the interrupt processing shown in FIG. The interrupt process is also executed when the communication from the karaoke playing device 5 is received.

As shown in FIG. 6, when the interrupt processing is started, the CPU 91 determines whether the communication that triggered the start of the interrupt processing is a notification of the end of the performance from the karaoke playing device 5 (S301). Here, an affirmative judgment (S301
If YES), the CPU 91 causes S302 to S30.
The process proceeds to No. 4, but here, the case of communication from the karaoke terminal device 19 (NO in S301) will be described.

If a negative determination is made in S301, C
The PU 91 proceeds to S305 to determine whether the request is a song from the karaoke terminal device 19, and if the determination is negative, terminates this interrupt processing and returns to the main routine.
On the other hand, if the request is for a song from the karaoke terminal device 19 (YES in S305), the CPU 91 proceeds to S306 and sends the request in S305 to the queue of the karaoke playing device 5 having the smallest number of waiting songs. The room number of the room in which the device 19 is installed and the requested song number are written, and the process returns to the main routine.

Here, the queue for each karaoke playing device 5 provided in the RAM 93 of the central controller 9 is shown in FIG.
Will be described with reference to. As shown in FIG. 8, in the cue table 96 formed in the RAM 93, each karaoke playing device 5a, 5b, ... 5x (each karaoke playing device 5
Queue columns 97a, 97b ... 97x are formed for each of the subscripts a, b ... Each cue column 97a to 97x is provided with a plurality of cue entry frames 98a, 98b ... 98x, and the requested song number and room number from the karaoke terminal device 19 are written in each cue entry frame 98a to 98x. The cue entry frames 98a to 98x correspond to the performance order of the karaoke performance devices 5a to 5x. The cue entry frame 98a is provided with the song number to be played next and the karaoke terminal device 19 requesting the song. The room number is written in the queue entry frame 98b and the queue entry frame 98c is written next in the queue entry frame 98c.

The new request is sent from the cue column 97a of the karaoke playing device 5a-5x having the smallest number of waiting songs.
It is written in 97x, but this writing will be described with a specific example. For example, a karaoke performance device 5a-
If the song to be played next is already written in the 5x cue entry frame 98a, and the next song to be played next is written in the cue entry frame 98b of the karaoke playing devices 5b to 5x, the waiting song. Since the karaoke playing device 5a has the smallest number (there is no next one), the song number and room number of the new request are the karaoke playing device 5a.
Will be written in the queue entry frame 98b. That is, the CPU 91 of the central controller 9 causes the queue entry frame 98
Search in order whether there is space in a, whether there is space in the queue entry frame 98b, or there is space in the queue entry frame 98c,
If a free space is found at an earlier stage, a new request is written in the queue entry frame 98a to 98x. In addition, the cue table is a karaoke performance device 5a ~.
It is updated each time one piece of music is completed in 5x, and the processing of S302 to S304 including it is described below.

When the affirmative determination is made in S301, the CPU 91 stores in the RAM 93 that the karaoke playing device 5 with which it has communicated is not playing (S30).
2). Subsequently, the CPU 91 notifies the karaoke terminal device 19 that has requested the song played by the karaoke playing device 5 that has notified the end of the song in S301, that the song has finished (S
303). Next, the CPU 91 instructs the RAM 93 to update the queue table 96.

The update of this queue table will be described with reference to FIG. For example, if the karaoke playing device 5a notifies the end of playing in S301, the CPU 91 instructs the RAM 93 to transfer the contents of the cue entry frames 98b to 98x of the cue column 97a to the upper cue entry frames 98a to 98w, respectively. To do. Thereby, for example, the contents of the queue entry frame 98b are transferred to the queue entry frame 98a, and the contents of the queue entry frame 98c are transferred to the queue entry frame 98a.
It is transcribed to b and the order of each request is advanced by one.

After executing such interrupt processing, C
The PU 91 returns to the processing of the main routine. Next, the processing of the main routine executed by the CPU 91 will be described with reference to FIG. As shown in FIG.
The U 91 searches for the karaoke playing device 5 that is not currently playing based on the contents stored in the RAM 93 in S 302 of the interrupt process (S 201). If there is a karaoke playing device 5 that is not playing here (YES in S201), C
PU91 advances to S202, and the karaoke playing device 5
Cue column 97a to 97x cue entry frame 98a
It is determined whether the song number and the room number are entered in (see FIG. 8). If there is a music application and room number in the corresponding cue entry frame 98a (YES in S202), the CPU 91
Displays the song number and room number in the queue table 96 (see FIG. 8).
Reference) (S203). Then, the CPU 91
Instructs the karaoke playing device 5 (not playing) detected in S201 to play the karaoke piece having the song number read in S203 (S204). In addition, the CPU 91
Notifies the karaoke terminal device 19 of the room number read in S203 of the channel number assigned to the karaoke playing device 5 instructed to perform in S204 (S20).
5) Return to S201.

Next, the processing executed by the karaoke playing device 5 instructed by the central control device 9 to play a karaoke piece (see S204 in FIG. 5) will be described with reference to FIG. As shown in FIG. 7, C of the karaoke playing device 5
The PU 52 (see FIG. 2) waits for a performance instruction from the central controller 9 (S401), and if there is a performance instruction (YES in S401), acquires the song number of the song to be performed from the central controller 9 (S402). ). Next, the CPU 52 transmits the song number acquired in S402 to the communication server 3 through the LAN interface 51, requests transmission of the karaoke song data of the song number, and receives the karaoke song data if it is transmitted. Then, it is stored in the RAM 53 (S403).

Subsequently, the CPU 51 reads the karaoke piece data from the RAM 53 and executes the processing for karaoke performance (S404). Specifically, the CPU 51 transfers the performance data included in the karaoke piece data to the sound source 56, converts the digital performance data into an analog performance voice signal, and outputs the analog performance voice signal to the modulator 15. In addition to this, C
The PU 51 transfers the lyrics data to the video synthesizing device 55 in synchronization with the performance data, and synthesizes (superimposes) the lyrics data and the background video signal output from the video device 7 into an analog display signal. It is sent to the modulator 15. The modulator 15 performs a predetermined high frequency modulation on the performance audio signal and the display signal and sends them to the head amplifier 13. Further, in the head amplifier 13, the high frequency signal input from the modulator 15 is sent to the trunk line 17 through the channel assigned to the karaoke playing device 5.

After completing the processing of S404, the CPU 51 notifies the central controller 9 of the end of the performance (S4).
05). Upon receiving this notification, the central controller 9 executes the above-described processing of S301 to S304 (see FIG. 5). Here, returning to the description of the processing executed by the karaoke terminal device 19.

As shown in FIG. 4, the karaoke terminal device 19
When the request is input to the terminal control device 21 of (S1
(YES in 01), the request music number is transmitted to the central control unit 9 (S102), and then the notification of the reproduction channel from the central control unit 9 is acquired (S103). This S1
The process of 03 corresponds to the process of S205 (see FIG. 5) by the CPU 91 of the central control device 9 described above.

Subsequently, the terminal control device 21 operates the tuner 23.
To select the channel acquired in S103 (S104). As a result, the modulator 15, the head amplifier 13, and the main line 1 are output from the karaoke playing device 5.
The high-frequency signal of the video signal and the audio signal corresponding to the requested music, which is carried by the device 7, is received and demodulated. The video signal demodulated by the tuner 23 is transferred to the display control device 28, and the audio signal is transferred to the amplifier 26.
Further, the video signal is displayed on the monitor 29 in a form in which the lyrics image is superimposed on the background image, and the user can sing while referring to the lyrics image. In addition, after the audio signal is amplified by the amplifier 26, the speaker 27L,
Sound output at 27R. At this time, the microphone 3
If the user's singing sound signal is input from 0, the amplifier 26
Are mixed with the audio signal at the speakers 27L, 27
Sound is output from R.

Next, the terminal control unit 21 receives the notification of the end of the music (see S303 in FIG. 6) from the central control unit 9 (S303) and returns to S101. As described above, in the karaoke information communication system 1 of the present embodiment, channels are assigned to each karaoke playing device 5, so that the same number of karaoke terminal devices 19 as the karaoke playing devices 5 can independently enjoy karaoke. . Further, even if there is a karaoke terminal device 19 waiting for the karaoke playing device 5 to be available, it is sufficient to wait for one of the plurality of karaoke playing devices 5 to finish playing, so that the waiting time can be shortened.

In this karaoke information communication system, for example, in an accommodation facility such as a hotel or a restaurant having a large number of private rooms, a karaoke terminal device 19 is installed in each room,
For example, if the central control device 9, the karaoke performance device 5, the communication server 3, etc. are installed in the management room,
You can enjoy karaoke in each room. At this time, all of the installed karaoke terminal devices 19 rarely send out song commands all at once, so the karaoke terminal devices 19
The number of karaoke playing devices 5 is less than that required.
Therefore, the karaoke playing device 5 and the karaoke terminal device 1
It is possible to enjoy karaoke in each room without installing 9 and 9 one by one, which is also excellent in cost efficiency. Moreover, since the lyrics are displayed on the monitor 29 together with the voice output of the karaoke performance, the user can enjoy karaoke while referring to the lyrics.

Although the present invention has been described above according to the embodiments, it is needless to say that the present invention is not limited to such embodiments and can be variously implemented without departing from the scope of the present invention. For example, the application of the information communication system is not limited to karaoke, but can be applied as long as it is a system in which an output terminal device separate from the information providing device is installed in a room or place where the use is expected.

[0050]

As described above, in the information communication system according to the first aspect, although there are more output terminal devices than the information providing devices, for example, accommodation facilities such as hotels and restaurants equipped with many private rooms. In the karaoke output terminals and the like installed in each room and the like, these are rarely operated all at once, and all the output terminal devices rarely simultaneously send out commands. Therefore, less information providing devices than output terminal devices can be used sufficiently, and it is sufficient to obtain external output in each room or place without installing one information providing device for each expected room or place. It is possible and cost effective.

In the information communication system according to the second aspect, since the channels are assigned to the respective information providing devices, it is possible to independently obtain the external output by the same number of output terminal devices as the information providing devices. When the information providing device is the karaoke playing device and the output terminal device is the karaoke terminal device as described in claim 3, karaoke can be simultaneously enjoyed by the same number of karaoke terminal devices as the karaoke playing device. Further, even if there is a karaoke terminal device that waits for the karaoke playing device to be available, it is sufficient to wait for one of the plurality of karaoke playing devices to finish playing, so that the waiting time can be shortened.

In the information communication system according to the third aspect of the present invention, for example, at an accommodation facility such as a hotel or a restaurant having a large number of private rooms, a karaoke terminal device is installed in each room, and a central control device is installed in, for example, a management room. By installing a karaoke performance device, you can enjoy karaoke in each room. At this time, all of the installed karaoke terminal devices do not simultaneously send the music command, and a karaoke playing device that is less than the karaoke terminal devices can be sufficiently used. Therefore, it is possible to enjoy karaoke in each room without installing the karaoke playing device and the karaoke terminal device in a one-to-one relationship, which is also excellent in cost effectiveness.

In the karaoke communication system according to the fourth aspect, the lyrics are displayed together with the voice output of the karaoke performance, and the user can enjoy the karaoke while referring to the lyrics.
