Thus, the karaoke machine with a display of the background video image, a song and music score or the like is realized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound reproducing method with video for displaying video together with, for example, karaoke.

[0002]

2. Description of the Related Art In recent years, there has been a strong tendency to view images and music in combination, and a typical example thereof is karaoke with images. For example, as shown in FIG. 1, the music for karaoke is reproduced from the speaker 1, and at the same time, the score and lyrics 21 of the song are displayed on the screen of the receiver 2, and further, as a background thereof, the music related to the song is related. The image 22 is displayed.

In order to realize this, conventionally, a background image in which lyrics are superimposed and music are produced for each karaoke piece and recorded on a video disc.

[0004]

However, in general, this kind of music has a relatively short life, and the product price is almost gone in a few years. Therefore, producing a karaoke video for each song as described above is extremely burdensome in terms of cost.

For this reason, the present invention is intended to realize karaoke on which a background image, lyrics, and score are displayed at a low cost for both the manufacturer and the user.

[0006]

[Means for Solving the Problems] Since the playing time of a song sung in karaoke is generally around 3 minutes, if different still images are displayed every 5 seconds during one song, 36 pieces per song are displayed. Still images are required. Further, if the still images are continuously reproduced and displayed, 30 still images are required per second, so that 5400 still images are required for one song. Then, in an optical video disc having a diameter of 30 cm, in a mode in which random access is possible, that is, in the CAV mode, since the reproduction time is 30 minutes on one side at maximum, 54000 still images can be recorded.

Therefore, when displaying still images that differ by 5 seconds during one song, if 54000 still images are assigned to the blocks dedicated to each song, 54000/36 = 15.
It will be for 00 songs. In other words, one video disc is 15
Images of 00 songs can be recorded, and 540
When 00 still images are continuously reproduced and displayed as a moving image, if the performance time per song is 3 minutes, images for 10 songs can be recorded.

[0008] However, in general, most of the music to be karaoke (there is a lot of enka) have similar contents, so that there are quite a few background images that can be shared even if the songs are different. Conceivable.

Therefore, it is possible to allow redundant use from among the background images recorded on one video disc and to extract an image corresponding to the content of each song for one song and use it as a background image. And if you do that, 1
The background image file formed on one video disk enables the background image for karaoke music to be supplied according to genres such as enka and pops.

On the other hand, to record the lyrics of karaoke, there are a character code mode for recording the digital code of each character of the lyrics and a graphic mode for recording the image data of the screen on which the lyrics are written. And the CD
The (compact disc) is a medium for digitally recording 2-channel high-quality music signals, but in addition to music signals, data such as characters and graphics can be digitally recorded in user bits.

Therefore, the karaoke lyrics can be recorded on the CD at the same time as the karaoke music signal in any of the above modes.

Further, the CD contains data about which of the still picture frames on the video disc is to be accessed and displayed in what order and at what timing. It can be written in the interval or in the recorded part of the song. And
Since it is considered that the data required to access the background still image for one song is about 100 bytes at most, it can be easily recorded between the songs of the CD.

Therefore, in the present invention, the background video signal is reproduced from the first medium in which the video signal as the background video is recorded, and the music signal of a plurality of music and the display signal of the lyrics corresponding to the music signal are reproduced. Reproduces the music signal and the lyrics display signal from the second medium recorded for each song, and superimposes the reproduced lyrics display signal on the video signal to monitor the background image together with the lyrics. The display of the background image is controlled by the specified signal supplied.
Control is performed to select and reproduce a predetermined background image on the first medium corresponding to each song of the music signal reproduced from the second medium, and the background image reproduced by this selection is the lyrics. The display signal is superposed and reproduced together with the music signal.

[0014]

According to the reproducing method of the present invention, the background image specified by the specifying signal is reproduced from the first medium at the same time as the music signal from the second medium and the display signal of the lyrics thereof are reproduced. And the lyrics are superimposed and displayed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 2, reference numeral 3 denotes a CD player, and the player 3 records the above-mentioned CD, that is, the music signal S _m of karaoke of, for example, 20 songs, and the music signal of each song is recorded in the player. The corresponding user's bit is set to the CD in which the code signal S _c of the lyrics of the karaoke and the page signal S _p designating the page (track) of the video signal as the background image on the video disc are set. There is. The signal S _c is recorded so that the lyrics are sequentially displayed as the music progresses, and the signal S _p is recorded so that the background image is updated every 5 seconds, for example.

Reference numeral 6 designates a video disc player, in which a still image suitable as a background image of karaoke is recorded, for example, over 54000 pieces and in the player 6 so as to be randomly accessible. A disc is set.

Further, 4 is an audio amplifier, 5 is a microphone, 7 is a video amplifier, and 8 is a graphic display processor.

When an arbitrary karaoke song is designated on the CD player 3, the karaoke music signal S _m is specified.
Is reproduced, and the code signal S _c of the lyrics of the karaoke and the page signal S _p designating the background image of the karaoke are reproduced. Then, the music signal S _m is supplied to the amplifier 4, and the voice signal S _a of the singing voice from the microphone 5 is supplied to the amplifier 4 and mixed with the signal S _m , and after power amplification, the speaker 1 is supplied. Supplied.

Further, a page signal S _p is supplied from the player 3 to the player 6, and a video signal S of a still image which becomes a background image of the karaoke from the page designated by the signal S _p.
v is reproduced, and this signal S _v is supplied to the amplifier 7.
Further, the code signal S _c from the player 3 is supplied to the processor 8, the signal S _c is decoded into a display signal (video signal) S _d for displaying lyrics, and this signal S _d is amplified by the amplifier 7.
To be superimposed on the signal S _v , for example.

Then, the signal S _v having this signal S _d is supplied to the monitor receiver 2.

Therefore, the karaoke singing voice is reproduced from the speaker 1, and the lyrics 21 are superimposed and displayed on the still image 22 of the background image corresponding to the karaoke song on the receiver 2. To be done. Then, the still image and the lyrics of the background image change as the song progresses.

Thus, according to the present invention, it is possible to realize karaoke with images. In this case, in particular, according to the present invention, a large number of background images are recorded on the video disc, the music signal and the lyrics are recorded on the CD, and the background image corresponding to the music signal is recorded from the video disc. Since it is selected and played, the maker does not need to create the background image software for each song, which is much lower cost. Also, for users, karaoke with images of abundant songs can be realized at low cost simply by purchasing a CD.

Furthermore, since the video disc can handle a large number of karaokes, there is almost no need to replace it, and only a few compact and lightweight CDs need to be prepared, which is convenient for handling and has a small storage volume. I'm sorry. Also, an autochanger can be implemented more easily than with a video disc.

In the above description, for example, as shown in FIGS. 3A and 3B, the signal S _v of the still image 22 such as various photographs and pictures is recorded on the video disk as an image, and one CD is shown in FIG. 21 characters displayed in English as shown in
A code signal S _c of, together with previously recorded and a sound signal S _m of the utterance in English, the code signal S _c of characters 21 to be displayed in Japanese, as shown in FIG. 3B the other CD,
If you record the voice signal S _m of Japanese utterance,
It can be used for teaching English and Japanese simply by exchanging CDs.

Data for image access is not recorded on the CD, but it is recorded in an external ROM or the like, and the corresponding data in the ROM is read from the song name data on the CD to read the data in the video disc player. Can also be controlled. In this case, for example, a 1M-bit mask RO
With M, it is possible to control over 45,000 background images. In addition, this system has a feature that even if the version of the video disk for background video is changed, it can be easily coped with by changing the ROM.

Further, in the above description, the video disk is an optical type and the CD is also an optical type, but a capacitance type video disk and a DAD may be used.

[0027]

EFFECTS OF THE INVENTION Karaoke with video and music with video can be easily realized by using a medium (for example, a CD) in which music signal and lyrics data are recorded. Moreover, the cost in that case is much lower than that in the case where new video software is created for each music. Also, for users, karaoke with a variety of song images can be realized at low cost, which is a great advantage. Further, compared to media such as video discs that record images, media such as CDs that do not record images are compact and lightweight, which is convenient in handling and requires a small storage volume. Also,
This is easier to achieve than if the autochanger were a video disc.
