2. Description of the Related Art Conventionally, in a video karaoke system, video data and the contents of lyrics and performance data are recorded and reproduced for each song on a video disk, but for commercial use, several thousand per system. Since data for songs is required, it is necessary to prepare many video discs. For this reason, all the video discs are stored in a dedicated storage case and the video discs are manually replaced when necessary, or the discs are exchanged by using an auto changer.

[0003]

However, a karaoke system is often installed in a store having a relatively small area, and an automatic changer or a dedicated storage case for storing a large number of discs may put pressure on the operating area of the store. In addition, the manual operation of changing disks requires frequent manual operations to change the disks, which requires a lot of time and effort.

Another problem is that the background image displayed for the reproduced song is always the same, which is not interesting when the user repeatedly sings as a song. there were.

The present invention has been made in order to solve the above-mentioned problems, and paying attention to the fact that the ratio of the video data in the song data is extremely high, the video data is prepared on the karaoke system side. The purpose is to provide high quality, fresh images by eliminating the problems, reducing the load on the storage medium, reducing the size of the device, and avoiding the same image always being the same image.

[0006]

In order to achieve this object, the video karaoke system of the present invention has a receiving means for receiving video data distributed from a sender, musical tone information of a song, lyrics of a song, and the like. A read-out means for reading out arbitrary music piece data from a storage medium in which music piece data including a set of video signals is stored, a video signal output from the receiving means, and a video signal read out from the read-out means And combine,
And a video composition display control means for displaying on the display means.

[0007]

The receiving means receives the video data distributed from the transmission source, and the reading means arbitrarily selects from the storage medium storing the music data of the music and the music data which is a set of video signals such as the lyrics of the music. The video composition display control means synthesizes the video signal output from the receiving means and the video signal read from the reading means, and causes the display means to display.

A microphone 36 for the singer to input a singing sound is connected to the other audio input terminal of the audio amplifier 38. The audio amplifier 38 mixes the performance signal 34a and the singing signal 36a and outputs an acoustic signal 38a to the speaker 40. ..

FIG. 3 shows a CD to be inserted into the CD player 18.
32 shows a structure of music data 18c for one music. The music data 18c is composed of music data 50, lyrics data 18a and performance data 18b arranged in time series. The shaded portions in the figure correspond to the prelude portion 56, the interlude portion 58, and the rear performance portion 60, respectively, and indicate that there is no lyrics data in this portion. Immediately after the prelude section 56 is a singing section 56a.

FIG. 4 shows the musical tone contents defined by the musical tone data 50 and the channels (A to A) of the CATV tuner 24.
The correspondence table of C) is defined in the ROM 12.

Next, the operation of the karaoke system of this embodiment will be described with reference to FIGS.

The CATV broadcast 20 has three channels for background video dedicated to karaoke and always broadcasts. The contents of each channel can be adapted to various tunes of various karaoke genres. For example, in the present embodiment, as shown in FIG. 4, the channel has three types of enka style, new music style, and rock style for each musical style content.
One is prepared.

When the CPU 10 receives a performance instruction 16a for a song from the operation panel 16, it gives the CD player 18 an instruction 10a for reading out the content of the corresponding song.
The CD player 18 follows the read instruction 10a and reads C
The song data 18c is read from D32, and RAM14
The contents are once stored in. After that, the CPU 10
The content of the tone data 50 at the beginning of the song data 18c is confirmed, and an image corresponding to that is selected by the channel selector 2
The channel is designated to the CATV tuner 24 through 2. For example, when the tone data 50 is "2", it is found from the table of FIG. 4 that the tone is in lock, so the CPU 10 instructs the channel selector 22 to select channel C. In response to this instruction, the CATV tuner 24 starts outputting the lock-tone background video signal 24a.

Next, in order to start the performance, the performance data 18b in the music data 18c stored in the RAM 14
Are sequentially sent to the D / A converter 34, and the performance signal 34a
Convert to. The audio amplifier 38 uses the performance signal 34a.
Is amplified and a performance sound is generated by the speaker 40. When the performance data 18b reaches the beginning singing section 56a of the singing section, the CPU 10 transfers the lyrics data 18a to the video control section 26.
To generate the lyrics video signal 26a
The background image signal 24a output from the tuner 24 is combined with the image combining unit 28, and the output video signal 28a
Is output to the monitor receiver 30, and the content of the lyrics is displayed on the background image. When the lyrics display starts on the monitor receiver 30, the singer starts blowing the singing voice into the microphone 36. The singing sound that has entered the microphone 36 becomes a singing signal 36a, and the audio amplifier 38 plays the performance signal 34a.
Is mixed into a sound signal 38a, which is output as sound from the speaker 40.

Thereafter, the CPU 10 synchronously controls the sending out of the lyrics data 18a and the performance data 18b to generate the image content of the monitor receiver 30 and the performance sound of the speaker 40.

The present invention is not limited to the embodiments described in detail above, and various modifications can be made without departing from the spirit of the invention.

For example, the song data 18c is replaced by the tone data 50.
The same effect can be obtained by directly inserting the channel number of CATV instead of putting. In that case,
It is not necessary to have the table of FIG. 4 in the ROM 12.

Further, instead of automatically selecting the selection of the video signal 24a according to the tone, it is possible to provide a channel switch on the operation panel and select the channel as desired by the user.

Although there are three CATV channels in FIG. 4, the number may be one. At that time, although you cannot select the image depending on the tone, you can always enjoy the song with a new image.

Also, the music data 18 stored in the CD 32
About lyrics data 18a of c Lyrics video signal 26
If a is stored in the storage medium as it is, the video control unit 26 can be removed and directly input to the image synthesis unit 28.

Although the video source is CATV, terrestrial broadcasting or satellite broadcasting transmitted by public / private broadcasting institutions,
Furthermore, video data transmitted by a high-speed communication network such as an optical fiber can be used, and on the other hand, it can also be used in a private premises broadcasting network system.

[0026]

As is clear from the above description,
Since the video karaoke system of the present invention superimposes the lyrics display signal from the system side on the video signal obtained from the receiving device through broadcasting, it is necessary to provide a huge amount of video data for each song as compared with the conventional device. Therefore, the external shape of the device can be kept small, and various images at each time can be enjoyed by the user.
