2. Description of the Related Art Conventionally, a karaoke apparatus reproduces a compact disc or a cassette tape, mixes the reproduced performance with a voice sung by a person, and outputs the resulting sound. There is also known an apparatus that projects an image on a television screen according to a performance in order to excite the mood in the hall. In a karaoke apparatus using this video, an optical disk or the like is used as a storage medium (media). In this optical disc, for each song, performance data, which is information for performing a performance reproduction, and video data for performing a video reproduction corresponding to the performance are stored on tracks of one disk. . The performance / video is reproduced synchronously based on the two data.

[Problems to be Solved by the Invention] In the karaoke apparatus using video as described above, the ratio of video data to data stored on a medium (such as an optical disk) is very high, and the ratio of performance data is very small. It was something. In other words, the performance data that is most important for karaoke is much less than the auxiliary video data stored in one-to-one correspondence. for that reason,
The time that can be played from one media is limited to its storage capacity, and it can be played for about 1 hour, that is, only about 10 songs. To prepare hundreds of songs, the number of media is required And it was. As a result, a large space was required for storing the media. In addition, the media must be replaced frequently, and the replacement work is troublesome.

An object of the present invention is to solve the above problems, reduce the storage space for media, and eliminate the need for frequent media replacement.

Configuration of the Invention [Means for Solving the Problems] In order to achieve the above object, in a karaoke apparatus of the present invention, as shown in FIG. 1, video specifying data is composed of a plurality of screen data, A karaoke apparatus for reproducing music data based on music data composed of a plurality of video specific data synchronized with the progress of the performance data, wherein a selecting means M1 for selecting music data and a plurality of music data are stored. From the music data storage medium D1, the performance data of the music data selected by the selection means M1 is extracted, and the video specific data is read out in synchronization with the progress of the performance data, and a plurality of screen data of the read video specific data is read out. A data extracting means M2 for randomly extracting one from among them; a performance reproducing means M4 for reproducing a performance based on the performance data extracted by the data extracting means M2; From the video data storage medium D2 for storing a plurality of image data corresponding to the data,
Video reproducing means M4 for reproducing the video data of the screen data extracted by the data extracting means M2.

[Operation] In the karaoke apparatus of the present invention having the above configuration,
The video specifying data is composed of a plurality of screen data, and is reproduced based on performance data and music data composed of a plurality of video specifying data synchronized with the progress of the performance data. Then, when the music data is selected by the selection means M1, the data extraction means M2 extracts the performance data of the music data selected by the selection means M1, from the music data storage medium D1 storing a plurality of music data, Video specific data is read out in synchronization with the progress of the performance data, and one is randomly extracted from a plurality of screen data having the read video specific data. The performance reproducing means M4 is provided with a data extracting means M2.
The performance reproduction is performed based on the performance data extracted by. The video reproducing means M4 reproduces the video data of the screen data extracted by the data extracting means M2 from the video data storage medium D2 storing a plurality of video data corresponding to the screen data.

As described above, the song data storage medium D1 stores the video specifying data composed of a plurality of screen data, and the data extracting means M2 randomly extracts one from the plurality of screen data. As a result of this random extraction, even if the same music is selected, video reproduction based on different video data is possible, and the user is not bored.

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

FIG. 2 is a schematic configuration diagram of a karaoke apparatus as one embodiment of the present invention. The karaoke apparatus 1 includes an operation unit 3, a hard disk 5, an electronic control unit 7, a synthesizer 9, an amplifier 11,
It comprises a speaker 13, an optical disk reproducing device 15, and a CRT 17.

As shown in FIG. 3, the operation unit 3 includes a number key switch 31 which is a numeric keypad for the user to select a desired song.
And a start key switch 32 for instructing playback of a song
And a display 33 that displays the number of the selected song,
A signal corresponding to the operation is output to the electronic control unit 7.

The hard disk 5 stores later-described performance data and screen number data (storage capacity 100 megabytes), and outputs both data to the electronic control device 7 based on a signal from the electronic control device 7. The performance data is stored in MIDI (Musical Instrument Digital) which is a unified standard for communication procedures of electronic musical instruments.
Interfase), and the amount of data per song is about 100 kilobytes.

The electronic control unit 7 includes a well-known CPU 71, a RAM 72, a ROM 73, an operation unit interface 74, and a hard disk controller.
75, a synthesizer controller 76, an optical disk controller 77, and a bus 78 for interconnecting these components.

The synthesizer 9 is a sound source that receives performance data corresponding to MIDI from the electronic control unit 7 and converts the data into an audio signal, and outputs the audio signal to the amplifier 11. A microphone 19 is connected to the amplifier 11, and mixes and amplifies a singing voice signal from the microphone 19 and an audio signal from the synthesizer 9 to output a signal to the speaker 13, and
Drive 13

The optical disk reproducing device 15 extracts predetermined video data from the optical disk 16 storing video data composed of a plurality of types of video such as a rain scene, a port scene, etc., according to a signal from the electronic control device 7, and performs various signal processing. A video signal is output to the CRT 17 via the CRT 17.

Next, the audio / video reproduction processing executed by the electronic control unit 7 will be described with reference to the flowchart of FIG.

First, a signal from an operation unit for selecting a song is read (S100). Subsequently, it is determined whether or not the start key switch 32 has been turned on (S110). Start key switch
As long as the start key switch 32 is turned on, the process proceeds to the next process. That is, when the user inputs the song number of the song to be sung and confirms that the entry has been correctly made on the display 3 and presses the start key switch 32, the determination in step 110 becomes "YES" and the following The process moves on.

When the start key switch 32 is turned on, the music data set by the signal from the number key switch 31 is read from the hard disk 5 (S120).

Here, the configuration of data read from the hard disk 5 will be described with reference to FIG.

As shown in the figure, data d for each song stored in the hard disk 5 includes performance data d1 corresponding to MIDI,
It consists of screen number data d2 and is arranged in chronological order.
The screen number data d2 includes a plurality of screen numbers. In this embodiment, as shown in FIG. 5, four screen numbers are included in each screen number data d2. The screen number data d2 is merely for selecting the type of video (still image in the present embodiment) on the optical disk 16, and has a very small data amount. Therefore, it can be said that the screen number data d2 is mixed in the performance data d1. Also,
Since the storage capacity of the hard disk 5 is 100 megabytes in this embodiment, the data d for about 1000 songs can be stored in the hard disk 5.

When the data d is read in step 120, it is determined whether or not the data d is the performance data d1 (S130). When it is determined that the read data d is the performance data d1,
The data d (performance data d1) is output to the synthesizer 9 (S140). At this time, the synthesizer 9 converts the performance data d1 into an audio signal and outputs it to the amplifier 11. Therefore, music flows from the speaker 13. Step 130
In the case of "NO", that is, when it is determined that the screen number data is d2, a random number is extracted from among a plurality of (here, four) screen numbers included in the screen number data d2 using, for example, a random number. One screen number is output to the optical disk reproducing device 15 (S150). At this time, the optical disc reproducing device 15 extracts the video data corresponding to the output screen number from the optical disc 16 and converts the video data into a video signal.
Output to CRT17. For example, as shown in FIG.
In 1, since the read data d is the screen number data d2, the determination in step 130 is “NO”, and the screen numbers included in the screen number data d2 are 3, 5, 13, and 15, The video corresponding to the screen number randomly extracted from the four is output to the CRT 17. For example, if screen number 3 is extracted, the video corresponding to screen number 3
Output to CRT17. At time t2, the performance data d1 is read out, so that the determination in step 130 is "YES", and the performance by the synthesizer 9 is started. Screen number data d2 including four screen numbers 1, 4, 6, and 8 at time t3
Is read, the video data corresponding to one screen number randomly extracted from the four
The video extracted from 16 and displayed on the CRT 17 also switches. Similarly, at time t4, four screen numbers 2, 6, 9, 11
Of the screen number randomly extracted from the
Then, the video of the screen number randomly extracted from the four screen numbers 7, 10, 12, and 14, and at time tn, the four screen numbers 3, 5, and
The video is switched to the video of the screen number randomly extracted from 13,15. Note that even during the period when the screen number data d2 is being read, the performance data d1 is data corresponding to MIDI and the data amount of the screen number data d2 is extremely small, so that the performance is not interrupted at all.

After the processing of step 140 or step 150, it is determined whether or not to end the performance (S160). When an end command based on the data d is input or a stop key (not shown) is operated, this determination becomes “YES” and the process ends. End the routine. If “NO” is determined, the process returns to step 120, and the above process is repeated.

According to the karaoke apparatus 1 of the present embodiment described above, the data stored in the hard disk 5 is configured in a time-series manner by the performance data d1 and the screen number data d2 for simply specifying the type of video. Types of songs can be stored at once. Furthermore, screen number data d2
There are four screen numbers in it, and the video corresponding to one screen number randomly extracted from them is displayed, so the screen displayed even if the same song is selected differs from the previous People will never get tired. In other words, there are many variations when viewed as a whole video constituting one song. Further, since the image displayed on the CRT 17 is a still screen, a huge variety of screens can be stored on the optical disc 16. Therefore, it is possible to memorize many kinds of songs,
It is no longer necessary to replace the media as in the related art, and the storage space for the media is not required. Furthermore, although the screens are still images, the combination (switching) of the images enables creation of a wide variety of images, which is interesting for users and viewers. Further, since the performance data d1 is compatible with MIDI, it is possible to change the pitch, tempo, and the like.

Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments at all. For example,
Instead of the screen number data d2, a configuration may be employed in which a command to the optical disk reproducing device 15 is directly stored to reverse the screen color. Also, instead of a static screen,
Obviously, the present invention can be implemented in various modes without departing from the scope of the present invention, even if a screen such as a computer graphic can be used. The performance data d1 is the MI
Instead of supporting DI, digital recording data may be used. In the case of using a moving image plane, the data amount is large, but even for different songs, by using the same video data in the middle of the song or for the entire song, many types of songs can be stored in a small amount of video data. It is possible to correspond to.

Effect of the Invention As described in detail above, according to the karaoke apparatus of the present invention, since the video specifying data for specifying the video data is used, the data amount is reduced and the number of media can be reduced. Therefore, there is an excellent effect that it is possible to reduce the troublesome work of exchanging media and to reduce the storage space for media. Further, a plurality of video specifying data are stored in association with one performance data,
Since one of the plurality of video specifying data is randomly extracted, even when the same music piece is selected, the video can be reproduced based on different video data. Do not get tired of.
