Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides background video (BGV) on a TV monitor or the like.
The present invention relates to a karaoke device that outputs a performance from a speaker while displaying lyrics video together with a ground video.

[Prior Art] Conventionally, when singing along with a performance of a song in a karaoke machine, it is often the case that the lyrics are checked one after another while singing. I was using it.

Conventionally, lyrics data to be displayed on a TV monitor has been stored together with background image data on a video disc (VD) or the like. On the other hand, the music data that is the source of the performance output from the speakers is stored on a compact disc (
recorded on the CD).

[Problems to be Solved by the Invention] However, since background video data and lyrics data are mixed and stored on the same video disc,
When a karaoke user sings while looking at the lyrics of a certain song, the same background image is always displayed for the same lyrics, making it impossible to sing while looking at different background images. This was a major constraint on enjoying karaoke.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to enable a background image to be arbitrarily selected for displaying the same lyrics.

[Means for Solving the Problems] In order to achieve this object, the karaoke device of the present invention has the following features:
As illustrated in FIG. 1, there is a performance/lyrics data storage means M1 that stores performance data D1 and corresponding lyrics data D2 for each of a large number of songs, and background video data D3 regarding images that are the background of the lyrics. Performance data D1 and lyrics data D2 for one song are read out in synchronization with each other from the plurality of background video data storage means M2 and the performance/lyrics data storage means M1, and at the same time, one of the background video data storage means M2 is read out. A control means M3 for reading out the background video data D3, a performance playback means M4 for playing back the performance data D1 read out by the control means M3, and lyrics data D2 and background video data D3 read out by the control means M3. and a display means M6 for displaying the synthesized image data D4.

[Function] The karaoke apparatus of the present invention having the above-mentioned configuration has performance data D1 and lyrics data D2 corresponding to this performance data D1.
A large number of background image data D3 are stored in the background image data storage means M2, and are read out from the performance/lyrics data storage means M1 by the control means M3. The played performance data D1 is sent to the performance playback means M4, while the control means M
3, the lyrics data D2 read from the performance/lyrics data storage means M1 and the background video data D3 read from the background video data storage means M2 are superimposed by the video composition means M5, and the composite video data D4 is displayed by the display means M6. Send to.

That is, of the lyrics data D2 and background video data D3 that are displayed in a superimposed manner, the negative lyrics data D2 is stored in the performance/lyrics data storage means M1, and the other background video data D3 is stored in the background video data storage. The means M2 stores both data D2. Since the DBs are stored separately from each other, it is possible to handle the background video data D3 independently of the lyrics data D2.

[Example] Hereinafter, an example embodying the present invention will be described with reference to the drawings.

The mixing amplifier 4 also receives the singing audio signal S2 that the singer inputs from the microphone 13, and the mixing amplifier 4 mixes and amplifies the performance audio signal S1 and the singing audio signal S2. A synthesized audio signal S is input to the speaker 5, and the speaker 5 outputs the sound. The music reproduction device 3, the mixing amplifier 4, the microphone 13, and the speaker 5 correspond to the performance reproduction means M4 in the configuration of the invention.

The video disc (VD) 10 loaded into the video disc player 10a stores background video data D3, and the background video signal S4 read from this video disc 10 and converted into an analog signal is sent to the sync separation circuit 9. and a video synthesis circuit 11. This video disc 10 corresponds to the background video data storage means M2 in the configuration of the invention.

The synchronization separation circuit 9 separates horizontal and vertical synchronization signals from the background video signal S4, and is configured to output the synchronization signals to the synchronization adjustment section 8. Synchronization adjustment section 8
controls the VRAM 6 and the character generator (CG) 7 based on the synchronization signal, reads out the lyrics data 20 written in the VRAM 6, transfers it to the character generator 7, and also reads out the characters in the lyrics data 20 in the character generator. It is configured to generate a lyrics video signal S5 from the data 21.

The video composition circuit 11 is configured to superimpose the background video signal S4 inputted from the video disc 10 and the lyric video signal S5 inputted from the character generator 7, and guide the composite video signal S6 to the TV monitor 12. There is. The video composition circuit 11 corresponds to the video composition means M5 in the configuration of the invention, and the TV monitor 12 corresponds to the display means M6.

Next, the operation of the karaoke apparatus configured as described above will be explained.

The central control device 2 executes the processing operations shown in the flowchart shown in FIG.

The central control device 2 reads out the music data 14 from the compact disc 1 (S1), and determines whether or not what has been read out is the lyric display ON code 15 (S2). If the lyrics display ON code is not 15, the reading of the music data 14 is continued until the lyrics display ON code 15 is read (
S2-5l).

When the lyrics display ON code 15 is read, the next lyrics data index number 16 is read (S3), and the corresponding lyrics data index number 16 is read from the compact disc 1 based on this lyrics data index number 16.
(S4)
).

On the other hand, the synchronization separation circuit 9 separates a synchronization signal from the background video signal S4 output from the video disc 10, and outputs it to the synchronization adjustment section 8. Based on the synchronization signal, the synchronization adjustment section 8 sequentially reads out the lyric data 20 written in the VRAM 6 and transfers it to the character generator tofu. The character generator 7 generates a lyric video signal S5 based on the character data 21 in the input lyric data 20,
It is output to the video synthesis circuit 11.

The video synthesis circuit 11 synchronously superimposes the background video signal S input from the video disc 10 and the lyric video signal S input from the character generator 7, and sends the composite video signal S6 to the TV monitor 12. do. As a result, a composite image of the background image and lyrics image that are synchronized with each other is displayed on the screen of the TV monitor 12 (S
5).

The central control unit 2 moves on to reading the next pointer on the lyrics data 20 (S6) and determines whether the pointer is the lyrics data end code 22 (S7). If the lyrics data end code is not 22, the lyrics data 20 in the same block is further read from the compact disc 1 and written to the VRAM 6 (S4), and its character data 21 is read.
After generating a lyrics video signal S from the 3D lyrics video signal S, a composite video of the background video and the lyrics video is displayed (S5), the next pointer is read (S6), and the lyrics data end code 22 is determined (S5).
S7) is performed.

When the lyrics data end code 22 is read, the VRAM
6, all the lyrics data 20 for one block is written, and the lyrics image for one horizontal line is displayed on the screen of the TV monitor 12 together with the background image.

When the central control unit 2 determines that the lyric data end code 22 has been read, the central control unit 2 reads out the performance data 17 in the music data 14 from the compact disc 1 in order from the beginning (
S8). Then, the performance data 17 is sequentially sent to the music reproduction device 3 (S9). The music playback device 3 converts the performance data 17 into an analog performance audio signal S, and outputs it to the mixing amplifier 4. The mixing amplifier 4 amplifies the performance audio signal S1 and outputs it to the speaker 5. Performance output is performed.

The central control device 2 moves on to reading the next pointer on the music data 14 (510) and determines whether the pointer is the lyrics display OFF code 18 (S11). If the lyrics display OFF code is not 18, the next performance data 17 in the music data 14 in the same block is further read out from the compact disc 1 (S8), and the music playback device 3
Send to S9) and read the next pointer S10
) and determines the lyrics display OFF code 18 (Sll).

When the lyrics display OFF code 18 is read out, the video display on the screen of the TV monitor 12 is to be erased.S12)
Then, the next data read is the song end code 19.
It is determined whether or not (S13).

If the song end code is not 19, the process advances to reading the next phrase (block) in the music data 14 and repeats the above operations (81-813).

Through the above processing, the lyrics image displayed on the TV monitor 12 and the performance from the speaker 5 are organically linked. Furthermore, only the background video data D3 is stored on the video disc 10, and this background video data D3 is separated from the lyrics data 20.
The background image displayed on the TV monitor 12 has no direct relationship with the lyrics image and the performance output. Therefore, by exchanging the video disc 10, a different background image can be arbitrarily selected for the same lyrics image.

Note that the central control device 2 ends the process when it reads out the song end code 19.

[Effects of the Invention] As is clear from the detailed description above, according to the present invention, of the lyrics data and background video data that are superimposed and displayed, the lyrics data is stored in the performance/lyrics data storage. Since the background video data is stored in the background video data storage means and the lyrics data and background video data are separated, any arbitrary data unrelated to the lyrics data can be used as the background video data. This makes it possible to display different background images for the same lyrics image, thereby increasing the entertainment value of karaoke.
