Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reproducing apparatus for reproducing an image reproducing disk storing an image used as a background image of an image karaoke apparatus.

[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.

[0004]

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.

In addition, the scenery of summer is projected in spite of the song in winter (the seasonal feeling is not supported), or the idyllic scenery that does not match the speed of the song is projected. There may be cases where the person feels uncomfortable without being overwhelmed. In order to deal with this, it is sufficient to make the video for each genre separated from the contents of those songs, but for example, if it is divided into 6 genres, there are only 5 video patterns per genre, and karaoke users are always It gives an even stronger impression that there are only the same images.

On the other hand, the applicant of the present application filed Japanese Patent Application No. 5-1.
In No. 50866, from the edited video group consisting of two or more edited videos edited as the video content of the same genre,
It was proposed that the edited videos be randomly selected and that the videos that were combined be played in sequence. According to this proposal, 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, which leads to a compact storage space. The above-mentioned proposal produces the above-mentioned effect by devising how to read out the edited video in one disc. However, the present invention focuses on the disc unit to store the storage space. Even though we have achieved compactness such as
Another object of the present invention is to provide a video reproducing apparatus capable of supplying a background video for a long time, which makes the user feel as if there are many types of background video and does not get tired.

[0008]

The invention as set forth in claim 1 for achieving the above object is an image reproducing apparatus for reproducing a plurality of image reproducing disks storing images, wherein the plurality of images are reproduced. A disc selecting means for randomly selecting any one of the reproducing discs from the reproducing discs, and a disc reproducing device for reading and reproducing an image from the reproducing disc selected by the disc selecting means are provided. Characterize.

The invention according to claim 2 is a video reproducing apparatus provided with a plurality of reproduction systems for reproducing a plurality of video reproduction discs storing images, wherein any one of the plurality of reproduction systems is provided. System selection means for selecting a reproduction system, disk selection means for randomly selecting any one video reproduction disk from a plurality of video reproduction disks corresponding to the reproduction system selected by the system selection means, and the disk Disc reproducing means for reading and reproducing an image from the image reproducing disc selected by the selecting means.

According to a third aspect of the present invention, there is provided a video reproducing apparatus having a plurality of reproducing systems for reproducing a plurality of image reproducing discs storing images, wherein one reproducing system is selected from the plurality of reproducing systems. Selecting means, a disk selecting means for selecting any one video reproducing disk from a plurality of video reproducing disks corresponding to the reproducing system selected by the system selecting means, and selecting by the disk selecting means The combination of the disc playback means for reading and playing the video from the played video playback disc and the video playback disc of the above multiple playback systems that starts playback first in each playback system It is characterized in that it is provided with a combination changing means for changing the combination at the time of control.

According to a fourth aspect of the present invention, in the video reproducing apparatus according to the second or third aspect, the system selecting means randomly selects one reproducing system from the plurality of reproducing systems. It is characterized by

According to a fifth aspect of the present invention, there is provided the video reproducing apparatus according to the third aspect, wherein the disc selecting means reproduces any one of the reproducing systems selected by the system selecting means. It is characterized by randomly selecting disks.

The invention according to claim 6 is the above-mentioned claim 1,
2. The video reproducing apparatus described in 2, 4, or 5, wherein the disc selecting means selects all of the plurality of video reproducing discs once at the time of the random selection.
It is characterized in that it is configured to randomly select from the ones that are not selected once.

The invention according to claim 7 is the above-mentioned claims 1 to 6.
The video playback device according to any one of claims 1 to 3, wherein the video is configured as an edited video group including a plurality of edited video, and the disk playback means selects the video selected by the disk selection means. It is characterized in that the above-mentioned edited video is read out randomly from the playback disc and played back.

[0015]

According to the invention described in claim 1, the disc selecting means randomly selects any one of the image reproducing discs storing the image, The reproducing means reads out the video from the video reproducing disk selected by the disk selecting means and reproduces the video.

Conventionally, even if an edited video image is randomly selected within one playback disk, if the playback order is determined on a disk-by-disk basis, a video of a certain type of content is played back for a certain period of time. However, when the image of another kind of content is reproduced for the next fixed time, if the image is captured for a long time (relatively), the order of reproduction content becomes the same.

On the other hand, according to the present invention, the unity of the reproduction contents in the case of capturing for a long period of time is reduced by randomly selecting even the image reproduction disc unit,
Despite the compactness of the storage space, karaoke users can feel as if there are many types of background images and can supply them for a long time without being tired. Of.

It is also conceivable to eliminate the blank at the time of video switching by providing a plurality of playback systems for playing a plurality of video playback discs storing videos. Like, select any one reproduction system from a plurality of reproduction system by the system selection means,
Randomly selecting one of the video playback discs among the multiple video playback discs corresponding to the selected playback system and playing the video is also effective in terms of variation in the video content. is there.

The invention according to claim 3 is also provided with a plurality of reproduction systems, one of the reproduction systems is selected, and a video reproduction disc is selected from a plurality of video reproduction discs corresponding to the reproduction system. However, when the combination changing means performs reproduction control, the combination of the video reproduction discs of the plurality of reproduction systems that starts reproduction first in each reproduction system Change with combination.

Therefore, for example, even if the video reproduction discs are selected in sequence in the reproduction system, the combination of the video reproduction discs which starts reproduction first in each reproduction system is the combination in the previous reproduction control. Therefore, the connection of the video is different from the last time, and it is possible to realize the variation of the video content as a whole.

Also in this case, it is possible to randomly select any one of the video reproducing disks from the reproducing systems selected by the system selecting means as in the third aspect. Contribute to variation. Further, in the video reproducing apparatus according to claim 2 or 3, any one reproducing system is selected from a plurality of reproducing systems, but according to claim 4, the selection is performed at random. For example, if there are three systems, A, B, and C, rather than always A → B → C → A → B → C, for example, A → B → A → C → B → A or B → C. → B
Making the system selection random, such as → A → C → A, contributes to the variation of the video content as a whole.

In the video reproducing apparatus according to claim 1, 2, 4 or 5, when randomly selecting the video reproducing disks, as shown in claim 6, all of the plurality of video reproducing disks are selected once. Until it is done, it is good to select at random from the ones that have not been selected. If this is not the case, the same playback disc may be selected in succession because it is a random selection, so by not selecting the same one until all the discs have been selected once, the overall video content Contribute to the variation of.

Further, the video reproducing apparatus described in claims 1 to 6 relates to a method of selecting a video reproducing disk or a reproducing system, and the video in the reproducing disk is not particularly limited. On the other hand, claim 7
According to the invention described in the above, since the edited video is randomly read out from the edited video group consisting of the plurality of edited video and played back, further video contents are combined with the action and effect by the selection of the video playback disk or playback system. To achieve variations.

Of course, in the video reproducing apparatus according to the above-mentioned claims 1 to 6, even if the reproduction order of the edited video is fixed, the video contents can be varied only by the operation of the selection of the video reproducing disk or the reproducing system. It will happen. Even when the edited video is selected, as in the case of the video playback disc of claim 6, until all the edited videos are selected once, random selection is made from the ones other than the one selected once. It should be set to.

The NTSC video signal converted by the NTSC converter 44 is sent to the video mixer 24 of the commander 10.

Next, the video control processing of the video reproducing apparatus configured as described above will be described with reference to the flowchart of FIG. The user can select and reproduce the song to be sung by operating the operation panel 14 directly or by operating the remote controller 14a. When the user operates the reproduction of the music, a reproduction start command is sent 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 genres (A to E) of the selected music. Sent to.

The microcomputer 38 of the disc player 30 is
When there is a reproduction start command (S10: YES), the reproduction system is initialized to A (S20), and the reproduction drive is randomly selected from the eight drive units A to A in the reproduction system A (S30). Then, it is judged whether or not there are remaining chapters in the video reproducing disk of the current drive (in this case, the drive unit selected in S30) (S40), and if there is no remaining chapter (S40: NO), the reproducing drive is randomly selected again. Is selected (S50). Of course, there are remaining chapters in the first processing of S40 (S
(40: YES), shifts to S60, and randomly selects chapters according to the table. This table is configured to check what has been selected once and clear all chapters once they have been selected.
The selection in S60 is to randomly select from the chapters without this check.

After the chapter to be reproduced is selected in S60, it is judged whether or not reproduction is being performed in another system (system B for system A and system A for system B) (S7).
0), if not being reproduced (S70: NO), S100
Then, the playback of the selected chapter is started by the selected drive unit.

In the subsequent S110, the reproduction system is converted. That is, if the current reproduction system is A, B is set as the next reproduction system, and if the current reproduction system is B, A is set as the next reproduction system. Then, the process returns to S40, and the processes from S40 onward are performed on the reproduction system converted in S110.

When the reproduction is first performed by the reproduction system A, in the next S40, it is judged whether or not the reproduction system B has the remaining chapters in the image reproduction disc of the predetermined drive (S40). If there is none, the reproduction drive is randomly selected again (S50). If there are remaining chapters (S40: YES), chapters are randomly selected according to the table (S60). This table is the same as that in the above-mentioned reproduction system A, and is configured so that once selected, it is checked and all chapters are cleared when they are selected once.

Then, another system (in this case, reproduction system A)
In step S70, it is determined whether or not reproduction is in progress. If reproduction is currently being performed by the reproduction system A, it is determined in S80 whether or not a reproduction end command has come from the commander 10 side, and if not, the process returns to S70. Then, when the reproduction in the reproduction system A ends (S70: NO), in the reproduction system B, the reproduction of the selected chapter is started by the selected drive unit (S100). Then, in S110, the reproduction system is converted to A.

If there is a reproduction end command in S80 (S80: YES), both reproduction systems A and B are processed in S90.
The reproduction is stopped together, and this processing ends. By performing the process of FIG. 4 described above, the drive units to be reproduced are randomly selected in each of the reproduction systems A and B while alternately switching the two reproduction systems of A and B (S50).
Also, the chapters in the video playback disk to be played back in the drive unit are randomly selected. In this way, the images from both playback systems A and B are sequentially combined,
It will be displayed as a background image on the monitor television 56 (FIG. 1).

As described above, according to this embodiment, the drive units are randomly selected so that the video reproduction disc units are also randomly selected, whereby the order of the reproduction contents in the case of capturing for a long period of time is changed. Reduce identity,
Despite the compactness of the storage space, karaoke users can feel as if there are many types of background images and can supply them for a long time without being tired. . In other words, even if the edited video is randomly selected within one playback disc, the playback order is determined for each disc,
Video of a certain type of content is played for a certain period of time,
This is because the same content occurs in the order of the reproduced contents when captured for a long time such that the video of another kind of content is reproduced during the next fixed time, but this problem is solved in this embodiment. it can.

The present invention is not limited to such embodiments as described above, and can be carried out in various modes without departing from the scope of the present invention. For example, in the above embodiment, the number of reproduction systems is A and B, but it may be three or more. In that case, the reproduction system may be randomly selected. For example, if there are three systems, A, B, and C, rather than always A → B → C → A → B → C, for example, A → B → A → C → B → A or B → C. → B → A → C → A
This is because making the system selection random also contributes to variations in the video content as a whole.

On the contrary, even if there is only one reproduction system, it is effective in terms of variation of video contents. Even if only the reproduction system A is used in the above-described embodiment, randomly selecting the drive unit to be reproduced from A to A reduces the identity of the order of the reproduction contents in the case of long-term capture. is there.

As another embodiment, as in the above-mentioned embodiment, the reproducing systems A and B (though three or more may be used, of course) are selected, and the reproducing system is selected to reproduce from a plurality of drive units. However, the combination of the drive units that first start reproduction in each of the reproduction systems A and B during reproduction control may be changed from the combination during the previous reproduction control.

For example, using the example of FIG. 3,
In the reproduction systems A and B, the reproduction order of the drive units is, for example, A → A → A ... A and B → B.
→ B ... Even if it is fixed as B, the combination of the drive units that start reproduction first in each reproduction system is changed from the combination in the previous reproduction control. For example, start with the combination of A and B and then start with A and B.
If the playback ends at the end of, the next playback will not start from A and B, for example A and B
By changing the combination such as starting from A or starting from A and B, the connection of images is different from the previous time, and it is possible to realize variation in the image content as a whole.

Further, when randomly selecting a reproduction drive in S50 of FIG. 4, a table for checking the selected drive unit is provided as in the case of chapter selection in S60, and it is selected once until all are selected once. It is advisable to select at random from the ones excluded. Otherwise, the same drive unit may be continuously selected because it is a random selection.Therefore, by not selecting the same drive unit until all drive units have been selected, the video content as a whole is selected. Contribute to variation.
