Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video karaoke apparatus in which a reproduced video is used as a background of lyrics display and which can be enjoyed by singing along with accompaniment music.

[0002]

2. Description of the Related Art Conventionally, in a video karaoke apparatus, a video disk or the like in which video data, lyrics contents, and performance data are stored is reproduced for each song, but for commercial use, several thousand songs per apparatus are used. I needed to prepare a large number of video discs because I needed data. Then, a large number of these video discs are stored in a dedicated storage case and are exchanged for discs according to a request using an autochanger or the like. Therefore, an area occupied by a dedicated storage case for storing a large number of discs and an automatic changer becomes large, and there has been a demand for downsizing particularly for commercial use.

What has been realized as a proposal of this compactification is to store video data separately from music data and display it as a background image when the music is played. This background image data is often stored on a video disc. If, for example, one piece of image data contains 2 hours, one piece of image data for an enka will be recorded.
Generally, two types of video data are stored such that the video data for time and pops is one hour.

More specifically, a plurality of edited images are stored for about 4 minutes, which correspond to the songs for enka and pops. Then, the requested song is classified into enka or pop, and the request is enka → enka → pops → enka →
If it is the order of pops, for example, the video data is read and displayed in the order of enka->enka->pops->enka-> pops.

[0005]

However, in the above example, for example, assuming that one song is about 4 minutes, there is only 14 to 15 pieces of video data for each of the enka and the pops. You may get tired of feeling it as a background image. In particular, the images displayed corresponding to the beginning of the song are often impressive, but since there are only 14 to 15 image patterns for enka and pops, the same for karaoke users. There is a high possibility that it will give the impression that there is only video.

As another problem, if there are only two types of enka and pops as described above, the content of the song will
It can be mentioned that some things are not suitable for the taste. Enka is relatively applicable, but pops must include anime songs, nursery rhymes, and foreign folk songs. Also, although it is a winter song, the summer scenery is displayed (the seasonal feeling is not supported), or the idyllic scenery that does not match the speed feeling of the song is displayed.
There is a case where the image pattern of No. 5 cannot handle the image pattern and gives a feeling of strangeness.

In order to deal with this, it is only necessary to divide the contents of those songs into genre-specific images. For example, if the genre is divided into 6 genres, there are only 5 image patterns per genre. It will give people a stronger impression that they always have the same image.

In view of these problems, the present invention has a short total time of the video information stored in the video information source, and therefore has achieved a compact storage space and the like, but karaoke It is an object of the present invention to provide a video karaoke device that can supply a user with a background image that makes the user feel as if there are many kinds of background images and does not get tired.

[0009]

A video karaoke apparatus according to claim 1, which has been made to achieve the above object, has a configuration as shown in FIG.
As illustrated in FIG. 3, selection means M1 for selecting a desired song from a plurality of karaoke songs, tone information output means M2 for reproducing and outputting tone information of the selected karaoke song, and video information are stored. The image information storage means M3, the image information read means M4 for reading the image information from the image information storage means M3, the lyrics information to the image information read by the image information read means M4, and the music information output means M2. Image display means M for displaying in accordance with the output timing of
And a plurality of sets of the above-mentioned video information storage means M3 and video information reading means M4,
The video information of each of the video information storage means M3 is configured as an edited video group consisting of two or more edited videos edited as video content of the same genre, and controls the plurality of video information reading means M4. An edit video read control means M6 is provided which randomly selects and sequentially reads the edit video from the edit video group stored in each of the plurality of video information storage means M3.

The video karaoke apparatus described in claim 2 is different from the video karaoke apparatus described in claim 1 in that
In addition, a broken line portion and the like from the selection means M1 to the edited video read control means M6 are added. Specifically, the video information of each video information storage means M3 is a plurality of edited video groups respectively corresponding to a plurality of genres. The genre determining means M7 configured to determine the genre corresponding to the karaoke piece selected by the selecting means M1 is provided, and the edited video reading control means M6 is the genre determined by the genre determining means M7. The edited video is randomly selected from the edited video group and sequentially read.

[0011]

According to the video karaoke apparatus of the present invention configured as described above, when the desired music is selected from the plurality of karaoke music by the selection means M1, the tone information output means M2 outputs the selected music. The musical tone information of the selected karaoke song is reproduced and output.

On the other hand, the video information of each video information storage means M3 is constituted as an edited video group consisting of two or more edited videos edited as the video content of the same genre, and the edited video read control means M6 is provided with a plurality of videos. The information reading means M4 is controlled to randomly select and sequentially read the edited video from the edited video group stored in each of the plurality of video information storage means M3. Then, the video display means M5 synthesizes the lyrics information with the video information read by the video information reading means M4, and displays the lyrics information corresponding to the output timing from the musical sound information output means M2.

Therefore, the edited images in the plurality of edited image groups are randomly combined in sequence and the background image is displayed. For example, if one edited image is kept for about 30 seconds, six edited images will be combined in a song of 3 minutes, and a series of background images by the combination will be very many types. And since there are as many images as the number of edited images that can be displayed corresponding to the beginning of a song, even though the video information source is the same as a whole, for karaoke users, there are many types of backgrounds. I feel as if there is a video. Therefore, it is possible to supply a background image that the user does not get tired of using a small number of image information sources.

On the other hand, according to the video karaoke apparatus of the second aspect, the video information of the video information storage means M3 has a plurality of genres (for example, Enka winter, non-En winter, pop-up tempo, other than pop-up tempo. , General type, etc.)
It is configured as a plurality of edited video groups each having contents corresponding to. Then, the genre determining means M7 determines the genre corresponding to the karaoke piece selected by the selecting means M1.

The genre determination will be explained more specifically. For example, in the case of enka, the above-mentioned genre examples correspond to those for enka winter only, those for non-enka winter only, and both of them. Can be divided. In addition, other than pop-up tempo and pop-up tempo, those that correspond to only one general genre, those that correspond to two of those three genres,
It can be divided into those corresponding to all three genres.

Then, the edited video read control means M6 randomly selects the edited video from the edited video group of the genre thus determined and sequentially reads it. When the number of genres is increased, as described above, the background image more suitable for the content and taste of the song can be obtained, but the number of edited images in one genre is reduced accordingly. However, according to this device, basically, many kinds of background images can be obtained even by combining edited videos in the same genre, and some songs can be used in edited videos of other genres. By selecting edited videos that span a plurality of genres as well, more types of background videos can be obtained.

Therefore, although the image information sources are the same as a whole, the karaoke user feels as if there are many kinds of background images, and the background images more suitable for the content of the song are displayed. Obtainable. Therefore, it is possible to supply a background image that the user does not get tired of using a small number of image information sources.

This is a modulation / demodulation device that performs demodulation. In the karaoke system of the present embodiment, since new songs are always provided, data of new songs is sent from the host computer (not shown) to the commander 10 through the modem 18 at night over a telephone line. It is stored in the hard disk 20.

The hard disk 20 is a storage device for storing performance data and lyrics data as music data. As performance data, data based on the MIDI (Musical Instrument Digital Interface) standard is stored. The MIDI sound source 22 stores performance sounds of various musical instruments, and is a sound source that generates performance signals of musical instruments based on performance data sent from the hard disk 20. The generated musical instrument performance signal is sent to the amplifier mixer 50.

The video mixer 24 is a hard disk 20.
This is a device for synthesizing the lyrics data sent from the computer and the NTSC video signal sent from the disc player 30. The lyrics data inverts the lyrics in synchronization with the output of the musical instrument to inform the user of the corresponding singing portion.

Next, the disc player 30 will be described with reference to FIG.
Will be described. Disc player 30 is commander 1
The disc player sends a video of the corresponding genre to the commander 10 as an NTSC video signal based on the genre information of the music transmitted from 0. The disc player 30 reproduces a video reproduction disc (not shown) to generate a video signal.

The video reproducing disk used in this embodiment has the following features. Video playback disc is 12c
m is a CD (compact disc) size video disc in which video data is compressed and stored according to the MPEG standard. By being compressed, one CD-size disc stores one hour of video.

Further, the video reproducing disk of the present embodiment has
Images of five genres A to E are stored. Genre A is an image of the content corresponding to songs mainly in winter in the enka system, and Genre B is an image of content corresponding to the songs other than winter in the enka system. In addition, genre C is an image of content mainly corresponding to uptempo songs in pop music, and genre D
Is an image of the content that corresponds to songs other than Apoptempo in pop music. And the genre E is a general type. The general system is a video whose content mainly corresponds to genres other than enka / pops, and is adapted to, for example, animation and nursery rhymes.

Further, the videos of each of the genres A to E are configured as an edited video group consisting of 24 edited videos with one edited video being 30 seconds. That is, in this embodiment, each genre consists of 12 minutes of video. From now on, this 30-second edited video will be referred to as a chapter, and the chapter numbers will be expressed as A-1 to A-24. The 24 chapters in one genre are not associated with stories.

Next, the internal structure of the disc player 30 for reproducing such a video reproducing disc will be described with reference to FIG. As shown in FIG. 3, the disc player 30

The NTSC converter 44 and the like are provided.

The serial input / output circuit (SIO) 32 is an interface circuit for receiving the genre information of the selected music piece sent from the commander 10. First and second
Each of the players 34a and 34b is composed of a known changer section and a well-known player section (both not shown). The changer section is equipped with 10 video playback discs,
The video reproducing disk is replaced in a predetermined order or according to a command from the microcomputer 38. The player section plays back the video playback disc set by the changer section. The processing of selectively reproducing the video reproducing disk by the first and second players 34a and 34b is executed by the microcomputer 38.

The switching circuit 36 includes a first player 34 and a second player 34.
It is a circuit for switching which of the video signals output from a and 34b is sent to the data reading circuit 40. As will be described later in the description of the operation, since chapters of the corresponding genre are sequentially reproduced at random, the first and second players 34a and 34b can be switched and reproduced accordingly.

The microcomputer 38 is a microcomputer that controls the operation of the entire disc player 30. The processing executed by the microcomputer 38 will be described later with reference to FIGS. The data reading circuit 40 includes a sub-microcomputer 41, and is a device for reading an electric signal sent from the switching circuit 36 as digital data. The digital data read by the data reading circuit 40 is sent to the compressed data decoding circuit 42.

The compressed data decoding circuit 42 is an electric circuit for decoding the compressed digital data sent from the data reading circuit 40 into a video signal. The video signal decoded by the compressed data decoding circuit 42 is sent to the NTSC converter 44. The NTSC converter 44 is an electric circuit that converts the video signal decoded by the compressed data decoding circuit 42 into a commercial color television signal (NTSC). The NTSC video signal converted by the NTSC converter 44 is sent to the video mixer 24 of the commander 10.

Next, the video / performance control processing of the video karaoke apparatus thus configured will be described with reference to the flowcharts of FIGS. First, it is determined whether or not there is a genre input (step 100. Hereafter, step is represented as S), and if there is a genre input (S100: YE).
S) and S110. The genre input will be described here. Karaoke user uses remote control 14
When the operation panel 14 is operated using a or the like to select a song,
The controller 12 in the commander 10 determines the corresponding genre of the song and sends it to the disc player 30.
The following processing is performed in response to the transmitted genre.

The corresponding genre indicates which genre of A to E can be used as the background image of the selected song. And in the case of this embodiment,
Genres A to E correspond to only individual video images (denoted as genres A, B, C, D, and E), and one type corresponding to both two genres A and B (genre AB. And 3 types (genre C) corresponding to 2 genres of the 3 genres of pop type and general type.
D, CE, DE) and one type (genre CDE) that corresponds to all three genres of pop type and general type.
It is divided into 10 types in total.

In S110 to S190, it is determined whether the input genre is one of the above 10 types. Then, as a result of each determination, S200 to S1100
As shown in, processing for each genre is executed. In addition,
If it is determined in S190 that it is not the genre DE, it is not necessary to particularly explain the shift to the genre CDE processing (S1100), and thus the description thereof is omitted.

Genre A shown in S200 to S1100,
Of the 10 types of processing for B, C, D, E, AB, CD, CE, DE, and CDE, the processing for genre AB (S700) will be described with reference to FIG. In the process for the genre AB, first, it is determined whether or not a reproduction start command is input from the controller 12 (S710), and if there is a reproduction start command (S710: YES), the first and second players 34a, 34b. The player number P to be reproduced is set to 0 (S720). The player number P has "0" and "1". In the present embodiment, when the player number P = 0, the reproduction is performed by the first player 34a, and when the player number P = 1, the other second player 34b. It is set to play.

When the reproducing player is determined, a random number R is next generated (S730), and it is determined whether the random number R is 1 or more and 48 or less (S74).
0). If 1 ≦ R ≦ 48 (S740: Y
ES)), and the random number R is converted into a reproduction chapter number S (S750).

In the case of the example shown in FIG. 5, since the processing for the genre AB is performed only in the case of 1≤R≤48 in S740, the genres that can be supported are A and B. As described above, the genre A has 24 chapters of the chapter numbers A-1 to A-24, and the genre B also has the chapter number B.
This is because, since 24 chapters of -1 to B-24 are stored, a total of 48 chapters are candidates as reproduction chapters.

Next, the reproduction chapter number S will be described. In a memory (not shown) in the microcomputer 38, a table for associating the chapter numbers (A-1, A-2, etc.) assigned to each edited video for each of the above 10 types of genres with the reproduction chapter number S Is remembered. FIG. 6B shows a genre AB table. In this case, the reproduction chapter numbers S 1 to 24 correspond to the chapter numbers A-1 to A-24 respectively, and the reproduction chapter number S 25 to 25 to the chapter numbers B-1 to B-24. 48 correspond to each.

When only one genre corresponds, for example, as shown in the genre B table shown in FIG. 6 (A), the reproduction chapter number S for the chapter numbers B-1 to B-24. 1 to 24 correspond to each other. When three genres correspond, as shown in the genre CDE table of FIG. 6C, the reproduction chapter numbers S 1 to 24 correspond to the chapter numbers C-1 to C-24, respectively. , Chapter numbers D-1 to D
Reproduction chapter numbers S 25 to 48 correspond to −24, and reproduction chapter numbers S 49 to 72 correspond to chapter numbers E-1 to E-24.

Therefore, the process of S740 in FIG.
Genres A, B, C, D, and E corresponding to only one genre
In the case of the application processing, it is determined whether or not “1 ≦ R ≦ 24”, and in the case of the genre CDE processing corresponding to three genres, it is determined whether or not “1 ≦ R ≦ 72”. Becomes

Returning to FIG. 5, after converting the random number R to the reproduction chapter number S in S750, it is judged whether or not the other player (in this case, the player number P = 1) is reproducing (S760). ), If not playing (S76
0:; NO) Current player number (P = 0 in this case)
Playback of the chapter with the playback chapter number S is started by the player (S770). In the following S780, the playback player is converted. That is, the player number P is
If the present is “0”, it is converted into “1”, and if the present is “1”, it is converted into “0”. Then, the process returns to S730 and the following processes are repeated.

The first time is reproduced by the first player 34a having the player number P = 0 set in S720, and the second time is being reproduced by the other player (in this case, the first player 34a) (S760). : YES),
It is determined whether or not a reproduction end command is input (S79).
0), if the reproduction is not completed (S790: NO), the process returns to S760. Then, when the other player, the first player 34a is not playing (that is, the previous playing has ended) (S760: NO), the second time is played by the second player 34b with the player number P = 1. (S770).

In this way, the reproduction by the first player 34a and the second player 34b is sequentially repeated. If it is determined in S790 that the reproduction has ended, the first and second players 34a. The reproduction is stopped together with 34b (S795), and this processing ends.

By performing the processing of FIG. 5 described above,
Video reproduction discs (discs: 1, discs: 2) that are respectively reproduced by the first and second players 34a, 34b.
The chapters in genres A and B in () are randomly combined in sequence, and the monitor television 56
It is displayed as a background image in (FIG. 2). For example, in a three-minute song, six chapters will be combined.
An example thereof is shown in FIG. In this case, the disc starts from chapter A-2 of disc 1: A-1 of disc: 2; B-3 of disc: 1; A-24 of disc: 2; A-3 of disc: 1; Are sequentially reproduced in the order of B-3.

As described above, a series of background images obtained by combining chapters every 30 seconds are very many kinds. And, even in the same genre (genre AB in this case), the images that can be displayed corresponding to the beginning of the song are the number of corresponding chapters of disc: 1 and disc: 2, that is, 48 × 2 = 96 in this case. Because there is only
Although the video source is the same as a whole,
For karaoke users, it feels as if there are many types of background images. Therefore, with few video information sources,
It is possible to supply a background image that does not make the user tired.

In addition, it is not just a classification such as for enka and for pops, but in this embodiment there are five genres (enka for winter,
Enka is used for non-winter, pop-up tempo, non-pop-up tempo, general system), and the number of genres is increased. Therefore, a background image more suitable for the content and taste of the song can be obtained. When the number of genres is increased, the number of edited videos in one genre is reduced, and in the past, karaoke users had the impression that they always had the same video, but according to this device, it was divided into five. In addition to those that correspond to only one genre of a song, some songs can be used in edited videos of other genres, so by selecting edited videos that span multiple genres, Many kinds of background images can be obtained.

As described above, the present invention is not limited to such embodiments, and can be carried out in various modes without departing from the scope of the present invention. For example, in the above-mentioned embodiment, the genre is divided into five genres, but more genres can be considered. In addition, as shown in FIG. 7, the first player 3
4a and the second player 34b are adapted to play the video playback disc alternately, but they do not necessarily have to be alternate. Since it is only necessary to be able to reproduce at random, for example, even the same video reproduction disc may be continuously reproduced as long as it is a continuous chapter.

In the above embodiment, the first player 34a
And the second player 34b played back from two systems of video sources. However, it has three or more systems of video sources and read-out means (player etc.) so that the reproduced video can be read out randomly and displayed. May be.

Further, in the above embodiment, when the karaoke user operates the operation panel 14 using the remote controller 14a or the like to select a song, the controller 12 in the commander 10 judges the genre corresponding to the song and disc player. Thirty
However, the controller 12 sends only the music selection information to the disc player 30 side, and the disc player 3
The microcomputer 38 in 0 may be configured to determine the genre corresponding to the song.

[0055]

As described in detail above, according to the karaoke apparatus of the present invention, the total time of the video information stored in the video information source is small, and therefore the storage space and the like can be made compact. Regardless, it is possible to provide a karaoke user with a background image that makes the user feel as if there are many types of background images and does not get tired.
