[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a karaoke device, and more particularly to a karaoke device that reproduces an image in accordance with an accompaniment sound.

[0002]

[Prior art]

 As a conventional karaoke device of this type, for example, a karaoke device including an optical disc and a reproducing device thereof is known. On the optical disc, voice data obtained by sampling accompaniment sounds and image data in which lyrics characters are combined with a background image are recorded for each song. Although the volume of such audio data and image data is extremely large, the storage capacity of an optical disc is generally large, such as several hundred MB, so that one disc contains about 1 hour of content, that is, about 10 songs with video and accompaniment. I was able to record together. Usually, hundreds of these optical discs are arranged so that you can select your favorite song from thousands.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional karaoke apparatus handles hundreds of optical disks, and thus has a problem of poor usability. For example, every time you select a song, you have to find the optical disc containing the song from a large number of discs and replace it with a playback device. There is also 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 in 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.

[0005]

[Means for Solving the Problems]

 As shown in FIG. 1, the karaoke apparatus of the present invention includes a selection means M1 for selecting a desired song from a plurality of songs, and an accompaniment of the selected song from an accompaniment storage medium M2 for storing accompaniment data. The genre data of the selected song is read from the accompaniment playing means M3 for reading and playing the data, and the genre storage medium M4 for storing the genre data of the song, and the video according to the mood of the genre is stored for each genre. The gist of the present invention is to include video reproduction means M6 for reading and reproducing a video corresponding to the read genre data from the video storage medium M5.

[0006]

[Action]

 In the karaoke apparatus of the present invention having the above-mentioned structure, when the selecting means M1 selects a desired song from a plurality of songs, the accompaniment reproducing means M3 reads and reproduces the accompaniment data of the selected song from the accompaniment recording medium M2. To do. Further, the video reproduction means M6 reads out the genre data of the selected song from the genre storage medium M4, and reads out the video along the mood of the read genre data from the video storage medium M5 and reproduces it. In this way, since the video according to the genre of the song is reproduced from the video, for example, even if there are thousands of songs, the karaoke device works with a significantly smaller number of videos than the number of songs. Therefore, the volume of data required for the karaoke apparatus is significantly reduced, and the number of times the accompaniment storage medium M2 and the video storage medium M5 are exchanged is reduced. No replacement is required. In addition, since the accompaniment storage medium M2 and the video storage medium M5 each require a small storage capacity, the storage capacity thereof becomes small.

【Example】

 In order to further clarify the configuration and operation of the present invention described above, a preferred embodiment of the karaoke device 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, the karaoke device includes a selection panel 1, a hard disk 2, a control device 3, a 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 in the song selection along with the song title.

The hard disk 2 has an event data storage area 21 and a genre data storage area 23. As shown in the explanatory diagram of FIG. 3, the event data storage area 21 stores the event data of the accompaniment part of each song published in the song collection in an area corresponding to the selection number of each song in the song collection. There is. The event data of the embodiment corresponds to MIDI signal data. The volume of the event data that constitutes the accompaniment portion of one 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. Genre categories include enka, military songs, classic, rock, and nursery rhymes.

The control device 3 includes a computer having a CPU, ROM, RAM, interface and the like built therein. Focusing on its function, it is roughly divided into an input unit 31, an output unit 33, and a central processing unit 35, as shown in FIG. 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 and 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 disk reproducing device 5 optically reads the data of the set optical disk, converts the data, and outputs a video signal to the CRT. As shown in the explanatory view of FIG. 4, the optical disc has image data for forming a plurality of images recorded therein. Each video is assigned a video number, which is composed of a genre to which the video belongs and a ranking number in the journal, as a number for identifying the video. All 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 machine, the user checks the selection number of the desired song from the song selection and inputs the selection number using the ten-key pad 11 of the operation panel 1. Next, after confirming that the input selection number is correctly displayed on the display unit 15, the start key 13 is pressed.

When the control device 3 executes the initial process after the karaoke device is activated, the control device 3 starts the music selection / playback routine shown in the flow chart 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 is operated to be turned on (S110). Until the start key 13 is turned on, the process of reading the signal from the key switch (S100) is repeated. 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, or immediately if the selection number is listed in the song collection, the accompaniment sound and video playback process described below is started. On the other hand, if the selection number is incorrect (S120), it is skipped to "RTN" and the signal reading process of the key switch (S100) and the process of judging whether the start key 13 is ON (S110) are repeated.

When 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). Then, from among the video numbers belonging to the genre of the genre data read previously, one video number is randomly determined by a random number (S140). Next, the determined video number is output to the optical disc reproducing device 5 to instruct the start of reproduction (S150). By this instruction, the optical disk reproducing device 5 starts reproducing the optical disk. Therefore, the CRT displays an image that matches the atmosphere of the selected song genre.

Subsequently, 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. The amplifier 41 sounds the speaker SP based on the audio signal and starts the operation.

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 is not finished (S180), the above-mentioned processing, that is, the processing of reading the event data from the hard disk 2 in a predetermined amount and outputting it to the synthesizer 4 (S160, 170) is repeated.

When the performance ends while repeating the processing of steps 160 and 170 (S180), the optical disk reproducing apparatus 5 is instructed to end the reproduction (S190), and then the process goes to "RTN" to end the present processing once. . 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 played back, even when about 1000 songs are recorded, the number of songs is remarkably high. The karaoke machine can be configured with a small number of videos, and the following excellent effects are achieved. That is, the number of times of exchanging the optical disc on which the image is recorded is extremely reduced. Or, replacement is unnecessary. The number of video productions can be significantly reduced. Furthermore, since multiple 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, which has the advantage of maintaining freshness.

In addition, since a very large number of songs (thousands of songs) can be recorded on the hard disk 2 by using event data in which the volume of data per song is remarkably small, the storage medium (conventionally several hundreds of optical disks) can be recorded. It has the excellent effect of eliminating the trouble of replacement. Since the installation space for one hard disk is extremely small, storage space will not be a problem.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention. is there. 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 jean 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, and configure the genres and the videos to 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.

[0026]

[Effect of device]

 As described above in detail, according to the karaoke apparatus of the present invention, the karaoke apparatus functions with a video number significantly smaller than the number of songs, and the volume of data required for the karaoke apparatus is significantly reduced. It is possible to reduce the number of times the accompaniment storage medium or the video storage medium is replaced. 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. As described above, the karaoke device of the present invention has an excellent effect that the usability of this type of karaoke device can be significantly improved.
