The video selection circuit 22 shown in FIG. 2 can be configured by, for example, a microcomputer. The CD player is equipped with an auto changer.

In the present embodiment, the method of determining the image from the selected song is, for example, by selecting the image of the motif suitable for the theme of each song. The content of each of the plurality of songs recorded on the CD is analyzed in advance, and a predetermined theme is given to each song. The contents of a plurality of images recorded on the LD are also analyzed in advance, and a predetermined motif is given to each image. As a result, the plurality of songs recorded on the CD are divided into themes, and the plurality of images recorded on the LD are divided into the motifs.

Each theme is coded and given a code corresponding to each song, and this code is recorded in a subcode of the CD for each song. Then, each motif is also coded, and the code corresponding to each video is given. This code is recorded in the LD subcode for each video.

A predetermined relation is designed in advance between the theme code and the motif code so that the image of the motif suitable for the theme of the song is selected, and the relation is a predetermined storage area of the image determination circuit. It is recorded in the form of a memory table.

The video is divided into, for example, the following 15 motif genres. ● Japanese flower and bird Fugetsu ● Bright southern sea ● Dark northern sea ● Festival ● Memories of youth (love record) ● Plateau / ranch / meadow ● Sweetheart ● Sweet image ● Large city image ● Hometown / country ● Travel ● Rain ● Tavern ● Youth setback ● Living alone.

The songs are divided into, for example, the following 13 theme genres. ● Patriotism ● Power / Inase (support song) ● Youth ● Unrequited love (first love) ● Burning love ● Sweet love song ● Hometown (memories) ● Nozomi (mother) ● Sorrow ● Sentiment ● Urban ● Farewell ● Tradition.

To determine the theme of a song, the brightness and darkness of the song are set on the X-axis, the energy level of the song is set on the Y-axis, and (X, Y) of each song is the voice of the song. And the lyrics thereof, and by applying this value to the image vector of FIG. 3, the theme of the song can be determined. Then, the same motif can be used to determine the motif of the image from the image vector of FIG.

By superimposing the image vector of FIG. 3 and the image vector of FIG. 4, the motif of the image can be determined from the theme (13 types) of the selected song as follows.

(1) Patriotism ● Japanese flower and bird Fugetsu, festivals,
(2) Power / Inase (supporting song) ● Festival, (3) Youth ● Bright South Sea ● Festival ● Memories of youth (love record) ● Plateau
Ranch / grassland ● Lover, (4) Unrequited love (first love) ● Bright southern sea ● Memories of youth (love record) ● Plateau / ranch / meadow ● Lover, (5) Burning love ● Lover ● Sweet image ● In a big city Image ● Rain ● Tavern ● Living alone, (6) Sweet love song ● Memories of youth (love record) ● Bright South Sea ● Highlands
Ranch / meadow ● Lover ● Sweet image ● Large city image,
(7) Hometown (memories) ● Japanese flower and bird Fugetsu ● Festival ● Plateau
Ranch / meadow ● Hometown / Countryside ● Travel, (8) Nostalgia (mother) ● Japanese flower and bird Fugetsu ● Dark North Sea ● Festival ● Highlands / ranch. Meadow ● Lover ● Sweet image ● Hometown / Country ● Travel ● Rain ● Living alone,
(9) Sorrow ● Dark North Sea ● Lover ● Big City Image ● Hometown / Country ● Travel ● Rain ● Tavern, (10) Sentiment ● Dark North Sea ●
Lovers ● Image of a big city ● Travel ● Rain ● Tavern ● Youth setback ●
Living alone, (11) City ● Lover ● Sweet image ● Large city image ● Rain ● Tavern ● Youth setback ● Living alone, (1
2) Farewell ● Dark North Sea ● Lover ● Big city image ● Rain ● Tavern ● Youth setback ● Living alone, (13) Tragic love ● Dark North Sea ● Lover ● Metropolitan image ● Rain ● Tavern ● Living alone.

Next, the operation of this embodiment will be described with reference to the flowchart shown in FIG. First, in step 500, when the desired song number is input to the CD player 18,
The digital signal of the selected song is output to the separation circuit 28 of the selection circuit 22. The signal separation circuit 28 separates the theme code recorded in the subcode of the selected song and outputs it to the video determination circuit 34 (step 501).

Next, in step 502, the image determination circuit 34 determines a motif code suitable for the theme code of the selected song, based on the storage table. Then, in step 503, this motif code is transmitted to the light receiving portion of the LD player 20 via the infrared remote controller 36 as the image selection control signal S5.

The process proceeds to step 504, and the LD player 2
0 determines the address of the subcode in which this motif code is recorded from the transmitted motif code.
In step 505, the signal of the video recording area including the subcode of the corresponding address is read out, and this video signal S6 is read.
Is output to the spar imposer 32 of the selection circuit 22.

Next, in step 506, the signal separation circuit 28 separates the character signal from the digital signal of the CD and outputs it to the character generator 30. In step 507, the character generator forms a character font from the character signal, superimposes the character font signal on the video signal from the LD player 20, and the superimposed video signal S4.
Is output to the television receiver 14. The television receiver 14 displays an image in which lyrics subtitles are formed.

On the other hand, the music signal S2 of the CD is output from the CD player 18, amplified by the amplifier circuit 16, and then synchronized with the video signal S4 and output from the speaker (step 508). The video is faded in (the video is gradually displayed on the screen of the television receiver), and at the same time, the character character is displayed overlaid on the video.

If the motif image being reproduced is shorter than the length of the music, the length of the image is adjusted by the following three methods, for example. The first method is that if the length of the motif image is shorter than the song by a predetermined time (for example, 10 seconds or more),
Fade out the end of the motif image being played (the image gradually disappears from the screen of the TV receiver),
Access the video of another motif that corresponds to the theme of this song, and play the video of this motif continuously with fade-in. For example, assuming that the theme of the song is (3) youth, and the first selected image has a bright southern sea motif, then: ● Memories of youth (record of love) ● Plateau, ranch, grassland ● Selected from lovers.

In selecting an image, in addition to a method of randomly selecting a specific image from an image group of motifs corresponding to the theme of a song, an image of a desired motif can be selected. A certain priority (priority) may be given to the motif image in advance, or the number of selections in the past may be recorded and the motif image with a large number of selections may be selected.

Next, the second method for adjusting the image length is
When the image is shorter than the song by a predetermined time (for example, 5 to 10 seconds) or when there is no other motif image shared by the theme of the song, the same motif image is returned to the beginning and reproduced. Then, in the third method, when the image is slightly shorter than the music (for example, less than 5 seconds), the end of the image being reproduced is the still screen. In the first to third methods, the length of each music piece and motif image is recorded in the CD and LD subcodes, respectively. The CPU of the image determination circuit 34 can perform such an operation by reading the lengths of the song and the image and comparing them. Then, the video is faded out at the end of the reproduction of the song. In the third method, the still point of the image may be a single point or a plurality of points in the middle of the screen.

The subcode in which the motif code or the theme code is recorded can be separated from the CD or LD by frame synchronization and then read by the software design of the control circuit. A user mode or reserve mode of R to W channels can be used as a subcode capable of recording the motif and theme.

According to the present embodiment, a plurality of songs having the same theme or different themes share the same motif image, so that the recording amount of the image can be significantly reduced, and as a result, the total capacity of the recording medium can be reduced. Is significantly reduced, and the drive unit and the like of the recording medium are reduced, so that the entire apparatus can be made compact. That is, one image may be prepared for each of the 15 motifs, and this image may be shared by a plurality of songs, and it is not necessary to record an image for each song. The music themes shared for each image of each motif are listed below based on FIGS. 3 and 4.

● Japanese flower and bird Fugetsu (1) Patriotism (7) Hometown (memories) (8) Boukyo (mother), ● Bright Southern Sea (3) Youth (4) Unrequited love (first love) (6) Sweet love song, ● Dark North Sea (8) Boukyo (mother) (9) Sorrow (10) Sentiment (1
2) Farewell (13) Tragedy, ● Festival (1) Patriotism (2) Power / Inase (support song) (3) Youth (7) Home (memory)
(8) Bokyo (mother) ● Memories of youth (record of love) (3)

Sweet Love Song (7) Hometown (memories) (8) Boukyo (Mother) ● Lover (3) Youth (4) Unrequited love (5) Burning Love (6) Sweet Love Song (8) Boukyo (Mother) (9) Sorrow (1)
0) sentimental (11) city (12) farewell (13) tragic love, ● sweet image (5) burning love (6) sweet love song (8) Bokyo (mother) (9) sadness (11) city, ● big city image ( 5) Burning love (6) Sweet love song (8) Bokyo (9) Sorrow (10) Sentiment (11) City (12) Farewell (13) Tragic love, ● Hometown / Countryside (1) Hometown (memories)
(8) Boukyo (mother) (9) Sorrow, ● Trip (7) Hometown (memory) (8) Boukyo (mother) (9) Sorrow (10) sentimental, ● Rain (5) Burning love (9) Sorrow (10) ) Sentiment (11) City (12) Farewell (13) Tragedy, ● Bar (5) Burning love (9) Sorrow (10) Sentiment (11) City (12) Farewell (1)
3) Tragedy, ● Youth failure (10) Sentiment (11) City (1
2) Farewell ● Living alone (5) Burning love (8) Bokyo (mother) (10) Sentiment (11) City (12) Farewell (13)
Tragic love.

In the conventional device, an image is recorded for each music piece, and the recording portion of the image in the LD is much larger than the recording portion of the audio, so that the total capacity of the recording medium is enormous. However, according to the present invention, the video recording portion of the recording medium can be significantly reduced by sharing the image of one motif among a plurality of songs, and the total capacity of the recording medium can be significantly reduced. Specifically, the recording amount of the image is 1/200 (it was calculated that the conventional image is 3000 images and the image of this embodiment is 15 images). As a result,
The volume of the entire device can be reduced to a fraction of the conventional volume. Then, if the motif is made as few as possible within the range where there is no practical problem in karaoke, all songs can be dealt with, so there is no harmful effect due to the limitation of the number of recorded images.

Further, according to the above-described embodiment, since the image of the motif suitable for the theme of the music is selected, it becomes possible to easily select the image.

In the present embodiment, since the analog video signal and the digital voice / character signal are separated and both are recorded in different recording media, the digitally recorded voice / character signal is recorded.
The character signal can be code-compressed. As a result, a larger amount of voice / character signals can be recorded on one CD, and the total capacity of the CD can be further reduced. And because the audio / character part and the video part are separated, it can be compressed with the most suitable compression method,
Very efficient.

Conventionally, it was possible to record a digital audio signal in the LD, but the difference in the information amount between the video signal and the digital audio signal is enormous, and even if the audio signal is compressed, it is recorded depending on the amount of the video signal. It is desirable to separate and compress the audio and video signals, as the total amount of possible signals will be determined.

ADPCM (adaptive differential pulse code modulation) encoding method, ADM (adaptive delta modulation) encoding method, and APC-AB (adaptive bit allocation predictive encoding) known as compression methods for digitally recorded voice / character signals. ) A coding method or the like can be applied. When the video signal is digitally recorded, it is desirable that the video signal be code-compressed using a VDI (video digital interactive) system or the like. Further, in this embodiment, analog recording of voice / character signals is not hindered.

The advantages of recording the audio / character signal and the video signal on different media will become apparent in the following cases. That is, when the audio / character signal and the video signal are recorded on the same medium as in the conventional case and the image is updated, a medium on which the audio / character signal and the video signal are recorded must be created again. I have to
The recording medium for the video portion may be recreated by recording the audio / character signal and the video signal on different media. As a result, it is extremely advantageous in terms of cost. Also,
You can also add songs and videos separately.

In this embodiment, the first recording medium is DVI, CD-ROM, CDI, I in addition to CD.
A recording medium having a short access time such as a C memory card can be used. As the second recording medium, in addition to the LD, a recording medium having a short access time such as an IC card, an optical card, a magneto-optical disk, a mini disk can be preferably used. Further, the image recorded on the second recording medium may be a still image in addition to the moving image.

Further, in the present embodiment, it is possible to select images of different motifs for each singular piece or for desired plural chapters. It is also possible to select a video motif and play a theme song that matches this motif. When selecting a song having a specific theme from the video motif, the determining circuit 34 determines the code of the specific theme from the code of the selected video motif based on a predetermined storage table, and the theme code Should be output to the CD player 18.

In the present embodiment, the manner of categorizing the themes and motifs is of course not limited to the description, and the criteria for associating the music and the video are not limited to the themes and motifs. Of course, other criteria could be used instead. As such a standard, for example, songs and videos can be divided by stars, regions, and the like. It should be noted that a plurality of criteria can be combined as the criteria for categorizing.

Further, although the case where lyrics are recorded on the CD has been described in the present embodiment, recording of lyrics can be omitted. Furthermore, when selecting an image from a song, a desired image can be selected regardless of the theme or motif. Further, in the above embodiment,
The control signal S5 from the image determination circuit is the infrared remote controller 36.
Is output to the player 20 via the control signal S
It is also possible to output 5 directly to the player 20.

In addition, enteral active programs such as DVI and CDI. When using media, this system is used interactively by using a touch panel system such as a television. Further, although the theme code and the motif code are stored in the recording medium in the above-mentioned embodiment, it goes without saying that the theme code and the motif code may be stored in the storage device of the computer.

[0051]

As described above, according to the playing device of the present invention, a predetermined image is selected from a plurality of images on the second recording medium in accordance with the selected song. Therefore, it is possible to make the playing device compact by significantly reducing the total capacity of the playing device on which the medium for recording images is occupied, without reducing the number of songs that can be played.

Since the music and the video are divided into genres according to the theme of the music and the motif of the video, and the motif video suitable for the theme of the selected music is selected, the music and the video are suitable for the content of the music. You can select the video. Since the motif of the image is determined from the theme of the song, the image for the song can be easily selected.

Furthermore, by separating the video signal and the audio signal, which are enormous amounts of information, and compressing the audio signal as a digital signal and recording it on a medium different from the video signal, the recording amount of the audio signal can be increased. Can be increased.
