DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video reproducing apparatus for reproducing a video reproducing disk on which a video such as a background video of a karaoke apparatus is stored.

[0002]

2. Description of the Related Art Conventionally, in a video karaoke apparatus, a video disk or the like in which video data, the contents of lyrics and performance data are stored for each music piece is reproduced. Because of the need for data, it was necessary to prepare a large number of video discs. Since a large number of video discs are stored in a dedicated storage case and replaced with a disk according to a request using an autochanger or the like, the area occupied by the dedicated storage case for storing many disks and the autochanger is large. In particular, compactness has been demanded especially for business use.

[0003] As one of the ideas for compactness, video data is stored separately from music data, and is displayed as a background image when the music is played. The video data serving as the background image is often stored on a video disc. For example, if one video data contains 2 hours, the video data for enka is 1 video data.
Generally, two types of video data are stored in such a manner that video data for time and pop is one hour.

[0004] More specifically, a plurality of edited videos which correspond to each of enka and pop are stored in about 4 minutes and are separated. Then, the request music is classified into enka or pop, and the request is enka → enka → pops → enka →
If the order is pops, for example, video data is read and displayed in the order of enka → enka → pops → enka → pops.

[0005]

However, in the above example, for example, one song is about 4 minutes, and there are only 14 to 15 pieces of video data for enka and pop songs. You may feel tired of feeling a background image. In particular, images that are displayed corresponding to the beginning of the song often remain impressive, but there are only 14 to 15 image patterns for enka and pop, which are always the same for karaoke users. There is a high possibility that the impression that there is only video is given.

Accordingly, the present invention has been made in view of such a problem, and a plurality of edited videos are combined to form a predetermined length.
Of multiple categories, assuming that
By combining edited images, images that make users feel as if there are many types of images and do not make users tired
And to provide an image reproducing apparatus capable of the test sheet.

[0007]

[0009] According to a third aspect of the invention, together with the edited video group is classified on the basis of the genre in addition to the above categories, the selection control means, in the editing image group corresponding to the genre of the designated tune there are, choose not to consecutive same category, to read the edited video from within the selected edited image group, which is a video reproducing apparatus according to claim 1 or 2, characterized in.

When the present invention is applied to a video karaoke apparatus, a video as a background video of the video karaoke apparatus is stored as an edited video stored on the video reproduction disk. It is preferable that each of the edited videos is configured to have a length of about 30 seconds so that a series of edited videos corresponding to one general karaoke song is at least four or more. In other words, "video of predetermined length"
Background video of one karaoke song (for example, about 4 minutes)
By combining four or more edited videos
Therefore, each edited video is set to about 30 seconds.

Further, in the above-mentioned inventions, it is conceivable that the categories are classified according to, for example, persons and landscapes. further,
When the invention according to claim 3 is used for a video karaoke apparatus, the genre is not limited to a rough classification such as enka or pops, but also to a season such as spring, summer, autumn and winter according to the content and taste of the karaoke song. Or may be finely classified according to the type of landscape or the like.

Such control is performed. That is, the same category is not consecutive
Select the edited video group as shown in the
Combine multiple edited videos read from
It is controlled so that an image is composed.

More specifically, this category can be divided into categories corresponding to, for example, persons and landscapes. If one edited video is set to about 30 seconds, a three-minute tune will be combined with three edited videos from two categories, for a total of six edited videos. Thus, despite the fact that the image information sources are the same as a whole, the karaoke user feels as if there are many types of background images. Also, since the same category is selected so as not to be consecutive by the selection control means, the video data to be reproduced is changed every 30 seconds from person → scenery →
The image is read out and displayed in the order of person → scenery → person, and a similar image does not continue for 30 seconds or more, and a background image that does not let the user get bored can be supplied with a small number of image information sources. Of course, there may be three or more categories.

Further, the present invention shown in Claim 2, 1 video
Playback discs store edited video groups of one category
And stored on multiple video playback discs
The edited video group is divided into multiple categories as a whole
It is configured. In addition, multiple video playback discs
Correspondingly, a plurality of disk reproducing means are provided.

[0015] The selection control means controls the plurality of images.
The disk reproducing means provided in correspondence to the playback disc
Select as the video playback disk that stores the edited video group of the same category is not continuous, disk re-has been the selection
The edited video is read from the edited video group on the video playback disc by the raw means . As a result, the edited movie
Video image is displayed in combination is consists of edited video same category is selected so as not to continuously Runode, when used as a background image of karaoke described above
In this method, a similar image does not last for 30 seconds or more, and a background image that does not cause the user to get bored can be supplied with a small number of image information sources. In addition, since playback is performed by a plurality of disk playback units, video switching can be performed quickly, which is preferable in terms of video continuity.

According to a third aspect of the present invention, the edited video group is classified based on a genre in addition to the category, and the selection control means is an edited video group corresponding to the genre of the designated music, The same category is selected so as not to be continuous, and the edited video is read from the selected edited video group. When playing a video along with a song, it is still preferable to use a video that matches the genre of the song. In particular, in a video karaoke apparatus, if a video of a genre corresponding to a specified karaoke song is played, the content is more suitable for the content of the song. Images can be displayed.

To further describe the genres corresponding to karaoke songs, if there are only two major categories, such as enka and pop, for example, some songs are unsuitable for the content and taste of the songs. For example, incongruity may occur due to incompatibility with the sense of the season or a tranquil scenery that does not match the speed of the song. In order to cope with this, it is only necessary to make a video for each genre that is further divided from the contents of the songs. However, when the number of genres is increased, the number of video patterns in one genre tends to decrease.

In this case, according to the present invention, in the genre, for example, as described above, person → scenery → person → scenery →
By combining images of a plurality of categories, such as by reading in the order of persons, it is possible to supply background images that will not let the user get bored even with a small amount of image information sources in genre units. This is very effective in a video karaoke apparatus.

The video reproduction disc of this embodiment stores videos of five genres A to E, respectively. The genre A is an image of content corresponding to mainly winter songs in an enka system, and the genre B is an image of content corresponding to songs other than winter in an enka system. The genre C is a video of a pop type mainly corresponding to an up-tempo song, and the genre D is a video of a pop type corresponding to a non-up-tempo song. Genre E is general. The general system is a video having a content corresponding to a genre other than enka / pops, and is adapted to, for example, an animation or a nursery rhyme.

Further, the videos of each of the genres A to E are configured as an edited video group including 24 edited videos, where one edited video is 30 seconds. In the future, the edited video of 30 seconds will be referred to as a chapter, and will be represented as chapter numbers A-1 to A-24. The video playback discs are classified into two categories. Category α is a video playback disc of person video data, and category β is a video playback disc of landscape video data. Each category α and β has five discs, that is, a total of ten discs.

Next, the internal structure of the disk player 30 for reproducing such a video reproduction disk will be described with reference to FIG. As shown in FIG.
Is a serial input / output circuit (SIO) 32, a first disc changer player (hereinafter, referred to as a first player) 3
4a, a second disc changer player (hereinafter referred to as a second disc changer player);

8, data reading circuit 40, compressed data decoding circuit 42,
An 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 sent from the commander 10. 1st, 2nd
The players 34a and 34b each include a well-known changer unit and a player unit (both not shown). The changer unit replaces five video playback disks of each of the categories α and β in a predetermined order or according to a command from the microcomputer 38. In this embodiment, the first disc changer 34a stores a video playback disc of category α,
Changer 34b selects a video playback disk of category β. The player section reproduces the video reproduction disc set and replaced by the changer section.
The process of selecting and reproducing the video reproduction 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.
This is a circuit for switching which one 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, the chapters of the corresponding genre are reproduced at random, so that the first and second players 34a and 34b are 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 FIG. The data reading circuit 40 includes a sub-microcomputer 41
And 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 a 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.

In this embodiment, the player 34
The changer sections a and 34b function as selection control means, and the player sections of the players 34a and 34b function as disc playback means. Next, the video playback control process in the video karaoke apparatus equipped with the video playback apparatus configured as described above will be described with reference to the flowchart of FIG.

The user can operate the operation panel 14 directly or the remote controller 14a to select and reproduce a song to be sung. When the user operates the reproduction of the music, the reproduction start command is transmitted from the serial input / output circuit 16 of the commander 10 to the serial input / output circuit 32 of the disc player 30 together with the genre (A to E) of the selected music. Sent to.

On the disc player 30 side, FIG.
As shown in (1), the system waits for the reproduction start command (Step 10; hereinafter, the steps are simply referred to as S). When the reproduction start command is issued (S10: YES), the first and second players 34a and 34b receive the reproduction start command. The player number P to be reproduced is set to 0 (S20). The player number P includes “0” and “1”. In this embodiment, when the player number P = 0, the reproduction is performed by the first player 34a, and when the player number P = 1, the reproduction is performed by the other second player 34b. It is set to play.

When the reproduction player is determined, a random numerical value is next generated to determine a reproduction chapter number S (S
30). If a genre is specified at the start of reproduction, the chapter number S is determined from the edited video group of the genre at this time. After the chapter number S is determined in S30, the other player (the player number P = 1 in this case)
(S40: NO). If not (S40: NO), the player of the current chapter number S is reproduced by the player of the current player number (P = 0 in this case). The reproduction is started (S50). The following S
At 60, the playback player is converted. That is, the player number P is converted to “1” if the current time is “0”, and is converted to “0” if the current time is “1”. And the S3
Returning to 0, the following processing is repeated.

The first time is reproduced by the first player 34a with the player number P = 0 set in S20, and the second time is when the other player (in this case, the first player 34a) is reproducing (S40). : YES), it is determined whether or not a reproduction end command has been input (S70). If the reproduction has not been completed (S70: NO), the process returns to S40. Then, the first player 34a as the other player
Is not being reproduced (that is, the previous reproduction has ended) (S40: NO), the second reproduction is performed by the second player 34b with the player number P = 1 (S50).

In this way, the reproduction by the first player 34a and the second player 34b is sequentially repeated. If it is determined in S70 that the reproduction has been completed,
First and second players 34a. The reproduction is stopped in both cases (S80), and the process ends.

By performing the processing of FIG. 3 described above,
Video playback disks (disc: 1, disc: 2) reproduced by the first and second players 34a and 34b, respectively.
To distinguish them. In this case, the disc 1 is a category α, and the disc 2 is a category β. )
The chapters of the corresponding genre are randomly and sequentially combined and displayed as a background image on the monitor television 56 (see FIG. 1). For example, in a three-minute song, three chapters from two categories are combined, for a total of six chapters. An example when the genre is C is shown in FIG. In this case, Disc 1 starts with chapter C-2,
The discs are sequentially reproduced in the order of C-1 of the disc 2, C-20 of the disc 1, C-15 of the disc 2, C-16 of the disc 1, and C-5 of the disc 2. As described above, since the category α is the person video data and the category β is the landscape video data, in this case, the reproduction is performed in the order of person → landscape → person → landscape → person → landscape.

As described above, since the video contents of the two categories α and β are switched at a fixed time (in this case, 30 seconds), the same video does not continue for more than 30 seconds. That is, a video of only a person or a video of only a landscape does not continue, and a background video that does not make the user tired can be supplied for a long time with a small number of video information sources.

Also, the pattern of a series of background images formed by combining chapters every 30 seconds is very large, and the karaoke user feels as if there are many types of background images. In addition, since the video playback disk of the embodiment uses a data compression technique, a one-hour video is stored on a CD-size disk.
Compared with the conventional video disc, the disc player 30
Has the advantage of being small. However, the same effect as that of the present invention can be obtained by preparing a plurality of categories of discs even for a conventional video disc.

In this embodiment, five genres (for enka winter, for enka winter,
For non-enka winter, pop-up tempo, other than pop-up tempo, general system) is provided to increase the number of genres. Therefore, a background video more suitable for the content and taste of the music can be obtained. When the number of genres is increased, the number of video patterns in one genre tends to be reduced. However, by combining videos of a plurality of categories, a background video that does not cause the user to get bored is provided by a video information source with a small number of genres. Therefore, it is possible to perform finer categorization, which is very effective in a video karaoke apparatus.

As described above, the present invention is not limited to such an embodiment, and can be implemented in various modes without departing from the gist of the present invention. For example, in the above embodiment, the first player 34a and the second player 34b
I played from the video playback disc of the category,
It is also possible to have video playback disks and disc playback means (players, etc.) of more than one category, and read and display the playback video so that the same category does not continue from those three or more categories.

In the above embodiment, one video playback disk stores edited video of only one category. However, for example, edited video of two categories α and β is stored in each video playback disk. You may keep it. In that case,
At the time of determining the playback chapter in S30 of FIG. 3, it is preferable to select an edited video belonging to a category different from the category reproduced immediately before by the other player. For example, when random numbers are generated with chapter numbers 1 to 12 as categories α and 13 to 24 as categories β, the method can be easily implemented if restrictions are provided.

It should be noted that this video reproducing apparatus is applied to
As described in the above embodiment, the video karaoke apparatus is mainly used, but the present invention is not limited to this. For example, the same can be applied to a case where BGM and BGV are simultaneously played in a restaurant or various event spaces.

[0051]

As described above, according to the video reproducing apparatus of the present invention, a plurality of edited videos are combined with each other.
Assuming that fixed-length video is played,
By combining the edited video of Gori, a bored to the user feel as if or else a large number there is a type of depression image
There is an effect that it is possible to supply feed video.

Further, if the reproduction is performed by a plurality of disk reproducing means, the video can be quickly switched, which is preferable in terms of the continuity of the video. Furthermore, according to the third aspect, an edited video group classified based on a genre in addition to a category,
Since the same category is selected so as not to be consecutive, especially when the video playback device is applied to a video karaoke device, if a video of a genre corresponding to the designated karaoke song is played, the content of the song can be further improved. An appropriate image can be displayed. When the number of genres is increased, the number of video patterns in one genre tends to be reduced. However, by combining videos of a plurality of categories, a video information source can be reduced in units of genres.
Since it is possible to supply a background video that does not cause the user to get bored, it is possible to perform finer categorization, which is very effective in a video karaoke apparatus.
