Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a karaoke system in which karaoke information is compiled into a database using an optical disk such as a CD-ROM.

[Conventional technology]

Conventional karaoke equipment plays back commercially available recording tapes or video discs on which karaoke songs have been recorded using a tape deck or video player, and then outputs the voice sung along with the karaoke songs from a speaker along with the performance. It is.

[Problem to be solved by the invention]

However, since the tapes and video discs mentioned above can only record eight songs for the former and about 20 songs for the latter, it would take an enormous number of volumes to cover all the karaoke songs released in the past. Therefore, not only does it take up a lot of space to store the tapes and disks, but it also takes a lot of time to select songs for karaoke.

The present invention creates a database of music, lyrics, and search information for karaoke songs using optical discs, thereby allowing most of the karaoke songs released in the past to be input into a single disc in a searchable manner and playable. The aim is to provide a system.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention provides karaoke songs that can be
I D I (Musical Instrument
In addition to digitally encoding the music information based on the ENT Digital Interface) standard, and converting the lyrics into text information, the karaoke data is stored on an optical disk, with search information such as the identification code and keywords of the karaoke song, and the database is stored in the CPU. an optical disc drive that is controlled to drive an optical disc; an input device that is connected to the CPU and that specifies search information to search for arbitrary karaoke data; a RAM that stores karaoke data; a sequencer, a synthesizer, which is connected to the CPU and reproduces and performs music information converted into a tIDI signal;
It is composed of a reproduction device consisting of an amplifier, a speaker, etc.

A method was also used in which the CPU of the karaoke system described above was connected to a host computer containing a database of karaoke data not recorded on optical discs through a public line.

[For production]

When you input the search information (identification code, etc.) for the desired karaoke song on the input device, the optical disc drive operates through the CPU to search to see if the input search information has been stored, and if it has, the optical disc drive is activated. The entire karaoke data with search information added to it is sent to R via the CPU.
Load into AM. The text information (karaoke song lyrics) is displayed on the display, and the music information is MIDI.
The signal is input to the playback device as programmed and played back as a karaoke song.

In addition, in a karaoke system connected to a host computer, if the input search information is not retrieved from the optical disk, the CPU determines this and immediately requests the host computer to transmit the desired karaoke data via a public line. The karaoke data is divided into text information and music information, and each is displayed and played back using the procedure described above.

〔Example〕

Hereinafter, the configuration of the present invention will be described in more detail based on an embodiment using a CD-ROM, which is one of the read-only types of optical disks. In FIG. On CD-ROM discs (MB), karaoke songs are digitally encoded based on the MIDI standard as music information, lyrics are converted into text information, and the song title, singer, composer, lyricist, etc. of the karaoke song are used as keywords. In addition, it is possible to input karaoke data of an average of 83 KB (kilobytes) for approximately 6,000 songs, including search information using unique symbols as identification codes. 2
is a CD-ROM that drives the above-mentioned CD-ROM disk 1.
Drive 3 is a CPU connected to the CD-ROM drive, which controls this drive to load karaoke data for one or more retrieved songs into the RAM. 4 is an input device such as a keyboard for inputting search information for a desired karaoke song; 5 is a display for displaying character information (lyrics) of karaoke data; 6
is a playback device, and the sequencer 7 plays a CD-RO
Of the karaoke data input from the M disk l to the CPU 3, the music information (M I DI double signal is output to an electronic musical instrument, for example, a synthesizer 8, and the music information output from the synthesizer 8 as an analog signal is amplified by an amplifier 9. Then, the speaker 10 reproduces the song as a karaoke song.

In addition, 11 is a host computer, which uses a database of new songs released after the creation of the CD-ROM disc 1, or karaoke songs that have been used very infrequently and was not recorded on the disc, and uses it as a database through the CPU 3 and the interface (1/F). It was connected by public line operator 2.

Next, the operation of the above-mentioned karaoke system will be described based on the flowchart shown in FIG. 2, take out the entire karaoke data with the above identification code from CD-ROM disk 1, and
Load into RAM via PU3. Among them, the text information (the lyrics of the karaoke song) is displayed on the display 5. On the other hand, the music information is outputted as a MIDI signal by the sequencer 7 to the synthesizer 8 as programmed, where it is converted into an analog signal, then outputted to the amplifier 9 for amplification, and then played back as a karaoke song through the speaker IO. Ru.

By the way, the identification code input to the CPU 3 is
- If the desired karaoke data is not on the ROM disk 1 (No), the CPU immediately requests transmission of the desired karaoke data to the host computer via the public line.

The karaoke data transmitted to the CPU is thus divided into character information and music information, and each is displayed and reproduced according to the procedure described above to supplement the database of the CD-ROM.

In addition to entering the identification code above, you can also select the desired karaoke song by directly entering a keyword such as the song title on the keyboard and searching for the song name from the search information. According to this method, the singer name or composition note name given as file information is typed into the keyboard 4, the related song titles are numbered and displayed all at once on the display 5, and the desired song number is entered again. The search function for karaoke songs will be improved, allowing you to easily select songs by inputting them.

In addition, as a means of displaying karaoke lyrics, you can display the entire lyrics on the display at once and change the color of the lyrics as the song progresses, or display one or two lines of lyrics that correspond to the progressing song. There are ways to display it. In this case, by inputting in advance into the music information a color change signal that is output to the display as the song progresses, it is possible to make the color change of the lyrics correspond to the progress of the song.

In addition, in the above karaoke system, a CD-ROM disk with a diameter of 12C1l was used as an example of an optical disk serving as a database, but it goes without saying that a larger disk (for example, 30Th) that can store a larger amount of information can be used. do not have.

[Effects of the Invention] As mentioned above, since the karaoke system of the present invention is a database of karaoke data consisting of music, text, and search information using an optical disk, most karaoke songs released in the past can be used. It can be recorded on a single disc and does not require a huge amount of storage space unlike traditional tapes, and it is easy to request songs by entering keywords such as the identification code or song title of the desired song using the keyboard. And it can be called quickly.

In addition, when a host computer is connected, new songs that have been released after the optical disc was created or songs that have been requested at a very low frequency (or songs that were not recorded on the disc) can be stored in a database on the host computer and can be transmitted and played over any public network. , this system can cover all karaoke songs.
