DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a centralized management device according to the present invention.

The control unit 10 controls the entire central management apparatus, and includes a well-known CPU, ROM, and RAM (not shown). Six video disks 12 are connected to the control unit 10.

[0013] The six video discs 12 are for the genre of songs such as enka, pops and new music.
The video data divided by is reproduced. In this embodiment, two video discs 12 are assigned to these three preferences.

Each of the six video disks 12 is connected to a modulator 20. Since the video data reproduced on the video disk 12 is a standard NTSC video signal, the modulator 20 converts the data into a frequency band of each channel and outputs an RF signal.

Each modulator 20 is connected to a head amplifier 24. The head amplifier 24 multiplexes an RF signal output from the modulator 20 and an RF signal output from a demodulator 22, which will be described later. Further head amp 2
4 is connected to the coaxial cable 26. Therefore, the video data reproduced from each video disk 12 is supplied to the coaxial cable 26 at different frequencies. On the coaxial cable 26, not only information transmitted from the central control device but also information transmitted from each karaoke terminal to the central control device is assigned a specific channel frequency.

The music data storage device 16 stores music data such as karaoke sound data, music titles, lyrics, and tunes. The music data is read out in accordance with the music selection information from the karaoke terminal, and transmitted to the karaoke terminal through the data input / output unit 14, the demodulator 22, the head amplifier 24, and the coaxial cable 26.

FIG. 2 is a block diagram showing the configuration of a karaoke terminal which is an audio device according to the present invention. One centralized management device includes a plurality of karaoke terminals and a coaxial cable 2

The demodulator 30 receives the music data transmitted from the central control device of FIG. 1 through the coaxial cable 26. In addition, music selection information to be described later is transmitted to the central control device of FIG.

The CPU 32 controls the entire karaoke terminal. An input device 34, a channel selection device 35, and a ROM 36 are connected to the CPU 32. The input device 34 is composed of, for example, a key panel, and is used to input a music number desired to be played. The music number input by the input device 34 is output as music selection information, and is transmitted to the central control device via the demodulator 30 and the coaxial cable 26. The channel selection device 35 outputs a channel selection signal for selecting one of the video signals flowing through the coaxial cable 26, based on the tune data of the music data received through the demodulator 30. . The ROM 36 stores programs and the like for controlling the karaoke terminal.

The video tuner 38 is a coaxial cable 2
6 is being received. The video tuner 38 is also connected to the channel selection device 3 via the CPU 32.
5 receives the channel selection signal, selects the video data flowing through the coaxial cable 26 in the channel from the video data on the coaxial cable 26, and outputs the selected video data to the video synthesizing circuit 52.

[0021] The memory 40 stores the music data received by the demodulator 30. Of the stored music data, the sound data is sent to the sound source 44 and converted into a sound signal,
Output. A microphone 46 for singing is also connected to the audio amplifier 48, and when audio is input from the microphone 46, the audio is mixed by the audio amplifier 48 and output from the speaker 50.

The music title and the lyrics data among the music data stored in the memory 40 are converted into lyrics video data by the video video circuit 42 and output to the video synthesis circuit 52. In the video synthesizing circuit 52, the video data output from the video tuner 38 and the lyric video data output from the video video circuit 42 are synthesized and output to the monitor receiver 54. The performance of the sound data and the display of the lyrics data in the sound source 44 are synchronized by the CPU 32.

Further, the tune data out of the music data stored in the memory 40 is used by the channel selection device 35 as described above.

FIG. 3 shows the music data storage device 1 shown in FIG.
FIG. Music data is track number 60a
, Song name 60b, tune code 60c, and sound data 6
0d and lyrics data 60e. The music selection information sent from the karaoke terminal is transmitted to the coaxial cable 2
6 is read into the control unit 10 of the central control device via the head amplifier 24, the demodulator 22, and the data input / output unit 16. The control unit 10 determines the music number 60a of the music data to be transmitted based on the music selection information, and
Name 60b, tune code 60c, music data 6 corresponding to
0d, the lyrics data 60e is transmitted to the karaoke terminal device as described above.

FIG. 4 is a flow chart and a diagram for explaining the operation of video data selection in the channel selection device 35 of the karaoke terminal. FIG. 4B is a table showing the correspondence between each channel of the video signal and the content of the video. As shown in FIG. 4 (b), an enka image is assigned to channels 1 and 2, a pop image is assigned to channels 3 and 4, and a new music image is assigned to channels 5 and 6. I have. Then, another video is flowing from channels 1 and 2, another video is flowing from channels 3 and 4, and another video is flowing from channels 5 and 6.

The operation of selecting video data corresponding to a music piece will be described below with reference to the flowchart shown in FIG.

The channel selection device 35 has a counter for counting the number of times the music is played for each music tone code.
The count value of the counter is reset to 0 when the operation of the karaoke terminal starts. In the present embodiment, there are three types of counters, a song counter that counts the number of performances of an enka, a pop counter that counts the number of times of pop music, and a new music counter that counts the number of times that new music is played.

First, when the karaoke terminal receives music data from the central control device, the tune data of the music data is read into the channel selection device 35 (S).
1). If the tune code is 0 (S2; Yes), the performance counter of the enka is incremented by 1 (S3). Subsequently, it is determined whether the performance counter of the enka is an odd number or an even number. If it is an odd number (S4; Yes), the video data of channel 1 is selected (S5). In the case of an even number (S4;
No), the video data of channel 2 is selected (S
6).

If the tune code is not 0 (S2; N)
o), the process proceeds to a determination as to whether or not the tune code is 1; if it is 1, (S7; Yes), the pop performance counter is incremented by 1 (S8). Subsequently, it is determined whether the performance counter of the pop is odd or even. If the counter is odd, (S9; Y
es), the video data of channel 3 is selected (S1)
0). If the number is even (S9; No), the video data of channel 4 is selected (S11).

Further, if the tune code is not 1 (S7; No), the process proceeds to a determination as to whether the tune code is 2, and if it is 2 (S12; Yes), the new music performance counter is incremented by one. (S13). Subsequently, it is determined whether the performance counter of the new music is odd or even. If the performance counter is odd (S14; Yes),
The video data of channel 5 is selected (S15). If the number is even (S14; No), the video data of channel 6 is selected (S16).

When the tune code is not 0, 1, or 2 (S12; No), no video data is selected, but this is not possible in the present embodiment.

In this way, for example, even if only enka is performed continuously, the video data is switched every time the music is played, so that the same video data continues to flow even after the next music is played. Nature is eliminated.

As described above, according to the present embodiment, the video corresponding to the tune of the music piece is selected from the six types of video data stored in the six video discs 12.
There is no need to have video data for each music piece as in the prior art. For this reason, the amount of data required per song can be significantly reduced.

In this embodiment, three tune codes are used,
Although two types of video data are provided for one tune, this number can be arbitrarily changed. For example, when three types of video data are provided for one tune,
The processing in 4, S9, and S14 may be branched into three types depending on the number of remainders obtained by dividing the value of the counter by 3.

In this embodiment, a video disk is used as a recording medium for video data. Instead of the video disk, various types of image memories such as a hard disk (CD-ROM) and a video tape can be used.

Also, music data may be stored as data conforming to the MIDI standard, and may include information for displaying lyrics in addition to music information. By constructing music data in this way, it is possible to construct a system in which music data is externally downloaded using a communication line, and the data is read and reproduced. If the present invention is constructed in such a system, new music data can be easily supplied at a relatively low running cost.

[0037]

As is apparent from the above description,
According to the centralized management system for audio devices of the present invention, when music pieces having the same taste are successively selected, the same taste and different video data are selected. Even if it is performed, the unnaturalness that the same image continues to flow is eliminated.
