In the embodiment of the present invention, when a video disc player of a type in which bit (recess) information formed on the surface of the video disc is reproduced using a microcapacitance electrode provided in a pickup is used as the above-mentioned reproduction device, the reproduction head Two microcapacitance electrodes are used as a component of 1.2.

Hereinafter, the combination of the on-screen circuit 4 (5) and the horizontal scanning counter circuit 6 (7,) will be described as a first setting circuit (second setting circuit).
setting circuit).

Playback device 3 with first and second playback heads 1.2
is a video disc (
(not shown) and plays a certain song. playback head 1
There are two output signals, and the audio signal is supplied to the amplifier 14 and amplified, and then output from the speaker 15.

The composite video signal from the playback head 1 is fed to an on-screen circuit 4. An on-screen circuit 4 for performing various processing on the supplied video signal for one frame (one image) is connected to a horizontal scanning counter circuit 6. The counter circuit 6 counts the horizontal synchronizing signal (hereinafter referred to as H or T1 signal) of the reproduced image.

For example, if the image for one frame consists of 1H to 525H and only the video signal of 1H'-4008 is to be reproduced, the counter circuit 6 counts only 1 to 400, and 40i -525 are not counted.

The composite video signal supplied to the on-screen circuit 4 is
Only the video signals of the images to be reproduced (video signals of 1F1 to 40011) set in advance by the counter circuit 6 are sent to the synchronization separation circuit 8.

The synchronization separation circuit 8 handles the H signal from this composite video signal and supplies only the video signal (first video signal) to the video synthesis device 11.

The composite video signal from playback head 2 is fed to on-screen circuitry 5. The on-screen circuit 5 is connected to a horizontal scanning counter circuit 7.

The composite video signal from the head 2 supplied to the on-screen circuit 5 is converted into a video signal 9 (4011
-1 to 525H video signals) are sent to the synchronization separation circuit 9. The synchronization separation circuit 9 extracts the H signal from this composite video signal and supplies the vertical synchronization signal (V signal) and the video signal (second video signal) to the video synthesis device 11.

Counter circuits 6 and 7 perform complementary counting operations.

For example, in the television system in which one frame of video reproduced by the television device 13 consists of 525 1-(Nobunaga), the counter 6.7 is a 525-decimal counter.

Therefore, while the counter circuit 6 stops counting from 1 to 400, the count circuit 7 stops counting from 1 to 400.
1 to 401 to 52' in response to the count stop of circuit 6
Count up to five.

For example, the video played on the television device 13 is
, the counter circuit 6 counts 1 to 525, and the counter circuit 7
is not counted at all.

The video synthesis device 11 synthesizes the two video signals supplied from the synchronization separation circuits 8 and 9. Here, playhead 1
The playback image of playback head 1 (2) overlaps with the playback image of playhead 2 (, within one frame,
) images are superimposed on areas where the playback head 2(1) does not play back (black images). Therefore, the two images are completely fitted within one frame.

The video synthesis device 11 is connected to an external synchronization generating circuit 12 and a video camera 16.

The video synthesis device 11 adds an external synchronization signal (for example, 525 H signals) to the synthesized video signal, and then sends this synthesized video signal @ (third video signal) to the television device 1.
Send to 3. Television device 13 reproduces this composite video signal.

The video synthesis device 11 is connected to a video camera 16, and a video signal from the camera 16 is supplied.

The audio signal from the microphone 17 is supplied to the amplifier 14 and amplified, and then output from the speaker 15, or mixed with the audio signal from the playback head 1 and output from the speaker 15.

The video disk used in the 8E playback device 3 has a recording portion divided into two parts, a first recording portion and a second recording portion.

On the disc, there is a first recording part (first recording part) and a second recording part (first recording part) on the inner circumference of the disc, and a second recording part (first recording part) on the inner circumference of the disc.
! (recording portion) are formed on the outer periphery of the recording portion (second recording portion) of the thick portion.

What is recorded in the first recording section for each song is the accompaniment melody as an A-dio signal, and a subtitle-only video signal (for example, white text with lyrics on a monochrome (black) background, or Music score).

What is recorded in the second recorded part are videos that are unrelated to the content of the song in the first recorded part, and are a series of videos without subtitles (for example, wind pressure without a story).
This is a video of the group.

Heads 1 + and l reproduce the first recorded portion, and head 2 simultaneously reproduces the second recorded portion.

The playback heads 1 and 2 consist of two playback heads that pick up data in the first and second recording portions, and a first control circuit that transports these heads to a predetermined recording portion, as will be described later. This control circuit is connected to the control device 10 (CPU21), and
A plurality of signals are exchanged between the two.

[J audio signal may be recorded in the second recording portion, but this audio signal is not used here.

Now, the process of requesting a song using the apparatus of the present invention will be described below.

The riffist of the song presses the song selection button on the control device 10 and specifies the chapter number of the requested song. The chapter number is the heading number of the song recorded on the disc.

FIG. 2 is a diagram showing an example of an operation part of the control device 10.

In the figure, reference numeral 18 indicates operation buttons, which include buttons rOJ to "9" for designating chapter 11 and a clear button "C" for canceling the designation. Reference numeral 19 is a disc side display section that displays the Δ and B side of the disc, and 20 is a music selection 7/' performance number display section that displays the chapter number of the designated song.

FIG. 3 is a block diagram illustrating how the control device 10 controls the playback device 1.2.

The control unit E10 includes a control unit (CPU) 21. Operation button 1
8. It consists of a display part 20 for music selection and 'Kinn flute'.

The control device 10 (CPU 21) is connected to the playback heads 1 and 2 and the video composition device 11.

The CPU 21 exchanges information signals (synchronization clock, address information, status information, data) with the reproduction head 1.2.

CPU 211. A control signal (for switching between the video signals from the playback heads 1 and 2 and the video signal from the camera 16) is sent to the J video synthesis device 11.

When making a request, if you specify the chapter number of the requested song using the button 18 (for example, press "2"), this input information is sent to the CPU 21;
1 is detected, a display signal is sent from the CPU 21 to the music selection 7' performance number display section 20, and the display section 20 lights up the designated chapter number M2J).

At the same time, a command code is sent from the CPU 21 to the playback head 1. The playback head 1 receives this command code and is transferred from the standby position of the playback head 1 to the chapter number position of the song from 99121 on the disc, and starts playing the requested song from this position 118.The playback operation of the playback head 1 is performed. In synchronization with this, the playback head 2 is also changed from the standby state to the playback state and starts playback from an arbitrary position on the disc.

In this way, the control unit 10 sends the video synthesis device 11 a message that the two video signals newly supplied from the playback heads 1 and 2 are combined and output instead of the video signal supplied from the video jy camera 16. A control signal is sent.

As described above, the audio Δ output signal from the playback head 1 is outputted from the speaker 15 via the amplifier 1/I, or mixed with the audio signal from the microphone 17 and outputted from the speaker 15.

The composite hitio signal from the playback head 1 (2) is fed to the on-screen circuit 4 (5) and counter circuit 6 (7).
Only the composite video signal of the reproduced image set in advance is sent to the synchronization separation circuit 8 (9), and the pre-synchronization circuit 8
The V signal and video signal from which the 1'' signal is extracted from the composite video signal supplied in step (9) are supplied to the video synthesis device 11. The video synthesis device 11 synthesizes two video signals supplied from the synchronization separation circuit 8.9. Video synthesis device 11
After adding an external synchronization signal to the synthesized video signal,
The synthesized video signal is sent to the preview device 13 and re/1:ed.

The video synthesis device 11 has a function of adding a superimposition effect to the video signal in addition to a function of creating a composite video signal by combining the synchronization of two video signals. The superimpose effect is the process of combining a prop image with an image without subtitles to create a new image with subtitles.

FIG. 4 is a diagram showing an image of the composite video signal synthesized by the image synthesizing device 11, in which the figure (△) shows the image from the playback head 1, the figure (B) shows the image from the playback head 2, and the same figure shows the image from the playback head 2. figure(
C) shows an image obtained by combining the images of playback heads 1 and 2.

As shown in the diagram, the image from Head 1 is black at the top of the screen and a subtitle image at the bottom (character image).
, since the image from Head 2 is an image without subtitles at the top of the screen (manga image) and a black image at the bottom of the screen,
When these images are combined, the upper part of the screen is a new image without the caption (manga image), and the lower part of the screen is a new image with the caption (character image).

What is shown in the diagram is the words "Wow! Woosso" (the text is included at the bottom of the composite screen, but the video containing only the lyrics of the song is composited with the video without the subtitles above). Of course, it would also be a good idea to combine a video containing both text and music with a video without subtitles.

The video synthesized by the video composition device 11 is played back from the television control device 13, and an accompaniment melody is played back from the speaker 15. At this time, if there is an audio signal from the microphone 17, the audio signal mixed with the accompaniment melody is output from the speaker 15.

In this way, a new video with a caption is created by combining a video with just the caption and a video without the caption. By changing the video without the caption as appropriate, it is possible to create a video with the same caption but with a different background image each time a request is made.

? In other words, even if you repeatedly request the same song, each time you request it, the video played by playback head 2 will start playing from a point where a video that is different from the video that was played the last time you requested it is recorded. In addition, it is possible to create videos with the same subtitle but with different background images.

In this way, when the reproduction of the requested song is finished, the playback RAD 1 returns to the end position and sends address information and status information to the CPU 21 indicating that the reproduction of the requested song has ended. In response to this, the CPU 21 selects music and displays the specified chapter number (r2J) on the /Hata number display section 20.
) sends a cancellation signal to cancel the display. Display section 2
0 is the designated ji pig number (r2J)
Cancels the display (turns off). At the same time, the CPU 21 sends a command code to the playback device @1 to stop the playback. After receiving this command code, the playback head 2 stops playback and enters a standby state.

In this way, the playback device 3 (playback heads 1 and 2) enters a standby state for receiving the next quest song. When the head 1.2 is in the standby state, the control unit 21 sends a control signal to the video synthesis device 11 to
A video signal from the camera 16 is sent to the television device 13 via the video composition device 11.

In this way, the video is always played back on the television LL%[13.

(Effects of the Invention) The present invention allows you to change the type of video and play it each time you play the same song.
It is possible to provide an A playback device with features that are not available in conventional video karaoke.
