Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a karaoke apparatus, and more particularly to a karaoke apparatus for reproducing an image in accordance with an accompaniment sound.

[Prior Art] As a conventional karaoke device of this type, a device including an optical disc and a reproducing device thereof is known. Audio data obtained by sampling accompaniment sounds and image data in which lyrics characters are combined with a background image are recorded for each song on the optical disc. Although the volume of such audio data and image data is extremely large, the storage capacity of an optical disk is generally large, such as several hundred MB, so it is possible to use only one optical disk.
I was able to record the contents of about time, that is, about 10 songs together with the video and accompaniment. Usually, hundreds of these optical disks are prepared so that a favorite song can be selected from thousands.

[Problems to be Solved by the Invention] However, the above-mentioned conventional karaoke apparatus handles hundreds of optical disks, and thus has a problem of poor usability. For example, each time a song is selected, the optical disc containing the song must be searched from a large number of discs and replaced with a playback device. In addition, there is a problem that a large space is occupied to store hundreds of optical disks. In addition, for every one of the thousands of songs, we had to make footage that matched the mood of the song.

It is an object of the karaoke apparatus of the present invention to solve the above problems and improve the usability of this type of karaoke apparatus.

Configuration of the Invention [Means for Solving the Problems] The karaoke apparatus of the present invention, as illustrated in FIG.
Accompaniment storage medium M2 for respectively storing accompaniment data corresponding to a plurality of songs, a genre storage medium M4 for respectively storing genre data corresponding to the plurality of songs, and selecting a desired song from the plurality of songs Selecting means M1 and accompaniment reproducing means M3 for reading and reproducing accompaniment data corresponding to the song selected by the selecting means M1 from the accompaniment storage medium M2.
A video storage medium M5 that stores a plurality of videos for each genre associated with the genre data, and genre data corresponding to the song selected by the selection means M1 from the genre storage medium M4. The gist is to provide a video reproducing means M6 for randomly reading and reproducing a video from a plurality of videos corresponding to the genre related to the read genre data.

[Operation] In the karaoke apparatus of the present invention having the above configuration, the accompaniment storage medium M2 stores accompaniment data corresponding to a plurality of songs,
The genre storage medium M4 stores genre data corresponding to the plurality of songs, and the video storage medium M5 stores a plurality of videos for each genre associated with the genre data. When a desired song is selected from the plurality of songs by the selecting unit M1, the accompaniment reproducing unit M3 reads out and reproduces the accompaniment data corresponding to the selected song from the accompaniment storage medium M2. At this time, from the genre storage medium M4,
The genre data corresponding to the selected song is read out, and the video reproducing means M6 randomly reads out a video from a plurality of videos corresponding to the genre related to the read genre data, and reproduces the video. In this way, since an image according to the genre of the song is reproduced from the image, the karaoke apparatus can function with a significantly smaller number of images than the number of songs even if there are thousands of songs. Therefore, the volume of data required as a karaoke device is greatly reduced,
The number of times the accompaniment storage medium M2 and the video storage medium M5 are exchanged is reduced. Alternatively, replacement becomes unnecessary. Further, since the accompaniment storage medium M2 and the video storage medium M5 each require a small storage capacity, the storage capacity thereof becomes small.

[Embodiment] In order to further clarify the configuration and operation of the present invention described above, a preferred embodiment of the karaoke apparatus of the present invention will be described below.

FIG. 1 is a block diagram of a karaoke apparatus as an embodiment of the present invention.

As shown in the figure, the karaoke device includes a selection panel 1,
Hard disk 2, control device 3, synthesizer 4
And an optical disk reproducing device 5.

The selection panel 1 includes a ten-key pad 11, a start key 13 and a selection number display section 15. The ten-key pad 11 is a key for inputting a song selection number. The start key 13 is a key for instructing the start of karaoke. The selection number will be posted along with the song title in the song collection.

The hard disk 2 has an event data storage area 21
And a genre data storage area 23. As shown in the explanatory view of FIG. 3, in the event data storage area 21, the event data of the accompaniment part of each song published in the song collection is stored in the area corresponding to the selection number of each song in the song collection. ing. The event data of the embodiment corresponds to MIDI signal data. The volume of event data that constitutes the accompaniment part of a song is generally several hundred KB. Therefore, the event data storage area 21 has a storage capacity of about 100 to 200 MB and can store event data of about a thousand songs.

In the genre data storage area 23, as shown in FIG. 3, genre data of each song published in the song selection collection is stored in an area corresponding to the selection number of each song in the song selection collection. The categories of genres are Enka, Military Song, Classic, Rock,
There are nursery rhymes.

The control device 3 includes a computer having a CPU, ROM, RAM, interface and the like. Focusing on its function,
As shown in the figure, the input unit 31, the output unit 33, and the central processing unit 35.
Is roughly divided into A ROM (not shown) pre-stores a procedure for executing music selection / playback processing.

The synthesizer 4 outputs a tone signal of various musical instruments or an audio signal for reproducing a sound effect based on the event data. The audio signal is input to the amplifier 41. A microphone 43 is connected to the input side of the amplifier 41. The output side of the amplifier 41 is connected to the speaker SP.

The optical disc reproducing device 5 optically reads the data of the set optical disc, converts the data, and outputs a video signal.
Output to CRT. As shown in the explanatory diagram of FIG. 4, the optical disc has image data for forming a plurality of images recorded therein. As a number for identifying each video, each video is given a video number that is composed of a genre to which the video belongs and a ranking number in the genre. Videos that are classified into the same genre are videos that follow the mood of that genre.

The karaoke device described above operates as follows. After activating the karaoke apparatus, the user checks the selection number of the desired song from the music selection and inputs the selection number using the ten-key pad 11 of the operation panel 1. Next, confirm that the selection number you entered is correctly displayed on the display unit 15, and then press the start key.
Press 13.

When the control device 3 executes the initial process after the karaoke device is activated, it starts the music selection / playback routine shown in the flowchart of FIG.

When the routine is started, a signal from the key switch of the operation panel 1 is read (S100), and it is determined whether or not the start key 13 has been turned on (S110). Start key
The key switch signal reading process (S100) is repeated until 13 is turned on. When the start key 13 is turned on (S110), it is determined whether the read selection number is correct (S120). If the selection number is correct, that is, if the selection number is listed in the music selection collection, the following accompaniment sound and video reproduction processing is started. On the other hand, if the selection number is incorrect (S120), the process skips to "RTN" and the process of reading the signal of the key switch (S100) and the process of determining whether or not the start key 13 is on (S110) are repeated.

If the selection number is correct (S120), first, the genre data stored in the area corresponding to the selection number is read from the genre storage area 23 of the hard disk 2 (S130).
Next, the video number of the video recorded on the optical disk is read from the optical disk reproducing device 5 (S135). And
From the video numbers belonging to the genre of the genre data that has been read previously, one video number is randomly determined by random numbers (S140). Next, the decided video number is output to the optical disc reproducing apparatus 5 to instruct the reproduction start (S150).
According to this instruction, the optical disk reproducing device 5 starts reproducing the optical disk. Therefore, the CRT projects an image that matches the mood of the selected song genre.

Then, a predetermined amount of event data stored in the area corresponding to the selection number is sequentially read from the event data storage area 21 of the hard disk 2 (S160), and the read event data is output to the synthesizer 4 (S170). The synthesizer 4 synthesizes the audio signal of the accompaniment sound based on the event data and outputs the audio signal to the amplifier 41. Amplifier
41 starts ringing the speaker SP based on the audio signal.

Next, it is determined whether or not the accompaniment performance has ended (S180).
The end of the performance is judged from the event data read in step 160. If the performance has not ended (S180), the above-described processing, that is, the processing of sequentially reading a predetermined amount of event data from the hard disk 2 and outputting it to the synthesizer 4 (S1160, 170) is repeated.

When the performance ends while repeating the processing of steps 160 and 170 (S180), after instructing the optical disk reproduction device 5 to end the reproduction (S190), the process exits to "RTN" and the present processing is temporarily performed.
finish. In response to the reproduction end instruction, the optical disk reproduction device 5 ends the reproduction.

As described above, according to the karaoke apparatus of the present embodiment, since the video according to the genre of the song is selected and reproduced, even when the songs of about 1,000 songs are recorded, the number of the videos significantly smaller than the number of songs. The karaoke device can be configured with the following excellent effects. That is, the number of times of exchanging the optical disc on which the image is recorded is extremely reduced. Alternatively, replacement becomes unnecessary. The number of video productions can be significantly reduced. Furthermore, since a plurality of videos are registered in one genre and the playback video is determined at random, different videos are played back even when the same song is sung, and there is an advantage that freshness can be maintained.

In addition, since the number of songs (around 1000 songs) can be recorded on the hard disk 2 by using the event data whose volume of data per song is remarkably small, it is troublesome to exchange the storage medium (conventionally several hundred optical disks). It has an excellent effect of eliminating the problem. Since the installation space for one hard disk is extremely small, the storage space does not pose a problem.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the scope of the present invention. For example, not the event data but the audio data obtained by sampling the accompaniment sound may be stored in the accompaniment storage medium, and the accompaniment reproduction unit may read the audio data and reproduce the accompaniment sound. As an accompaniment storage medium, a genre storage medium, and a video storage medium, any storage medium such as an optical disk, a magneto-optical disk, a magnetic tape, or a hard disk may be used. In the embodiment, the video to be reproduced is randomly determined from the videos of the same genre, but it may be determined by a cycle. Further, as in the embodiment, it is possible to divide the genre into a plurality of videos without registering a plurality of videos in one genre so that the genres and the videos have a one-to-one correspondence. In this case, there is an advantage that a more accurate image can be reproduced in the mood of the song.

EFFECTS OF THE INVENTION As described in detail above, according to the karaoke apparatus of the present invention, the karaoke apparatus functions with a video that is significantly smaller than the number of songs, and the volume of data required as a karaoke apparatus is significantly reduced. The number of times the accompaniment storage medium or the video storage medium is replaced can be reduced. Alternatively, replacement may be unnecessary. In addition, the number of videos produced can be reduced. The storage space for each storage medium can be reduced. in this way,
The karaoke apparatus of the present invention has an excellent effect that the usability of this type of karaoke apparatus can be significantly improved.
