Abstract

PURPOSE:To reproduce a requested music at any time while excluding intervention of mechanical constitution to the utmost by digitizing an orchestral accompaniment music requested for many number of times and storing it into a ROM, sending and reproducing other musics from a database of a host computer through a public line at any time and storing them in a RAM at the same time. CONSTITUTION:When an identification code given to a request music from a keyboard 8 is inputted, a CPU 5 controls a memory controller 4, retrieves a ROM 1 to find out a code from the ROM 1, extracts the entire orchestral accompaniment data, which is processed by the CPU 5. That is, song information is displayed on a display device 9, music information is outputted to a synthesizer 12 by a sequencer 11, converted into an analog signal to operate an amplifier 13 and a speaker 14. When the required information does not exist in the ROM 1, a RAM 2 is retrieved, and when the information does not yet exists therein, the CPU 5 retrieves the database of the host computer through a public line 7 immediately, writes the data in the RAM 2, from which the data is reproduced.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention digitally encodes frequently requested karaoke songs and stores them in a semiconductor ROM (hereinafter simply referred to as ROMJ), and other songs are made publicly available. The present invention relates to a karaoke system in which playback is performed directly from a database of a host computer connected via a line, or after data is saved in a semiconductor RAM (hereinafter simply referred to as rRAMJ).

(Prior Art) Conventional karaoke equipment plays commercially available recording tapes, video discs, etc. on which karaoke songs have been recorded in advance using a tape deck, video player, etc., and outputs the voice sung along with the karaoke songs from a speaker along with the performance. That's what I was trying to do.

[Problem to be solved by the invention]

However, the tapes and video discs mentioned above can only record 8 songs for the former and 20 songs for the latter, so y! ! Trying to cover it would require a huge number of volumes, and each time a new song was released, you would have to buy more tapes and discs one after another. Therefore, if you try to prepare the tapes and discs, you will not only have to spend a lot of money and take up a lot of space to store them, but you will also have problems selecting songs for karaoke.

In addition, the above karaoke machines are mostly installed in the water area of restaurants, but because the tapes and discs are taken in and out, the whole machine cannot be sealed tightly, so it can easily fail. There was a risk of malfunction due to the influence of water droplets and humidity that entered the disc, and since the tape was mechanically operated, the tape could stretch, the disc could be damaged, or there was a lot of wear and tear, making maintenance troublesome. was there.

The present invention eliminates mechanical configurations and digitally encodes the songs, lyrics, and search information of karaoke songs that are expected to be requested and stores them in the ROM, while storing songs not recorded in the ROM as a database in the host computer. The present invention attempts to provide a karaoke system in which a favorite karaoke song can be played at any time by downloading it to a RAM.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention provides karaoke songs with M
I D I (Musical In5uturu
The ROM is stored as karaoke data consisting of music information encoded based on the a+enL Digital Interface) standard, lyrics information displayed in text, and search information such as identification codes, and is connected to the CPU via a public line. a host combinator that creates a database of karaoke data other than that stored in the ROM;
A RAM for downloading the karaoke data of this computer, and a ROM and RAM under the control of the CPU.
Memory search device for searching M and arbitrary search conditions for CP
It consists of an input device that inputs into the U, a display that displays the lyrics information processed by the CPU, and a playback device consisting of a sequencer, an electronic musical instrument, an amplifier, a speaker, etc. that plays back the music information processed by the CPU. This is what I did.

Additionally, a method was used in which a bank-up battery was installed in the RAM.

[For production]

When the search conditions for the desired karaoke song, such as the identification code, are input using the input device, the memory search device operates through the CPU to search whether the above identification code is stored in the ROM, and if it is, it is identified. The entire coded karaoke data is read out and processed by the CPU. If the identification code is not stored in the ROM, it is searched to see if it is stored in the RAM, and if it is stored, the karaoke data with the identification code is input to the CPU and processed. Furthermore, the above identification code is RA
If it is not found in M, the CPU determines this and immediately searches the database of the host computer via the public line and sends the karaoke data with the above identification code to the CP.
At the same time, this data is written to RAM and saved.

The lyrics information of the karaoke data processed by the CPU is displayed as characters on the display, and the music information is input as a MIDI signal to the playback device as programmed, and is played back as a karaoke song.

Furthermore, if the RAM is equipped with a backup battery, the saved karaoke data will not be accidentally erased even if the power is turned off.

(Embodiment) Hereinafter, the configuration of the present invention will be described in more detail based on one embodiment. In FIG.
You can input an average of 80KB (kilobytes) of karaoke data for approximately 2,000 songs. The above karaoke data includes song information that digitally encodes karaoke songs that are expected to be requested based on MIDI standards, lyrics information that displays lyrics in text, song title, singer, composer, and lyricist. etc. as keywords,
It also consists of search information using a unique symbol as an identification code. 2 is a semiconductor R that can write or read the karaoke data at any time within a range of about 30 songs.
By adding a backup bath 3 to this AM, the stored contents will not be erased even if the power is turned off.

Note that the ROM and RAM mentioned above are used by connecting existing ones so as to have a predetermined capacity.

Further, 4 is a memory search device for reading out desired karaoke data from the ROMI and RAM 2, and 5 is a CPU that controls the memory search device and processes the searched karaoke data for one to a plurality of songs. 6 more
is a host computer that uses a database of new songs that were released after the ROMI was created, or karaoke songs that were used infrequently and were not stored in the ROMI, and the CPU
5 and a public line 7 such as a telephone line via a modem.

Note that when using 15DN as a public line, an interface is used in place of the modem, since direct digital communication can be performed.

Furthermore, 8 is the condition for searching for the desired karaoke song (r
an input device such as a keyboard for inputting a separate code, keyword, etc.; 9 a display for displaying lyrics information of the karaoke data; 10 a playback device; , music information (MIDI signal) is output to an electronic musical instrument 12 such as a synthesizer, and the music information output as an analog signal from the synthesizer is amplified by an amplifier 13 and then reproduced by a speaker 14 as a karaoke music.

Next, the operation of the above-mentioned karaoke system will be described based on the flowchart shown in FIG. 2. If the search conditions for the requested song are inputted on the keyboard 8, for example, the identification code consisting of symbols attached to all karaoke songs in advance, The CPU 5 controls the memory search device 4 to search the ROM 1,
If the identification code is found among them (YES), the entire karaoke data to which this identification code is attached is extracted and processed by the CPU 5. Of these, the lyrics information is displayed in text on the display 9. On the other hand, the music information is outputted as a MIDI signal by the sequencer 11 to the synthesizer 12 as programmed, where it is converted into an analog signal, and then outputted to the amplifier 13 for amplification.
Furthermore, the song is played back as a karaoke song through the speaker 14.

By the way, the identification code input to the CPU 5 is the ROM.
If the identification code is not found in I (NO), the RAM 2 is searched, and if the identification code is found here (YES), the character information and music information are displayed and reproduced by the above-described operations.

If it is determined that the identification code is not present in both the ROM and RAM memories, the CPU 5 immediately searches the database of the host computer through the public line 7 and transmits the karaoke data to which the identification code has been attached to the CPU 5. This transmitted karaoke data is stored in RAM2
While the song is written and saved, the lyrics are displayed on the display 9 and the song is played back from the speaker 14 in the above-described operation. In this case, if 30 songs have already been registered in RAM2, which is the capacity limit, and there is no free space, please delete songs that have been requested less often and have older registration dates in advance to create more storage space. .

In addition to entering the identification code in the above example, you can also select the desired karaoke song by directly entering a keyword such as a song title on the keyboard 8 and searching for the song name from the search information. According to the input method, the singer name or composition note name given as file information is entered on the keyboard 8, the related song titles are numbered and displayed all at once on the display 9, and the desired song number is entered. You can easily select songs by inputting again, etc.
The search function for karaoke songs will be improved.

In addition, as a means of displaying karaoke lyrics, the entire lyrics may be displayed on the display 9 at once, and the color of the lyrics may be changed according to the progress of the song, or one or two lines of lyrics may be displayed that correspond to the progressing song. One possible method is to display them one by one. In this case, in advance, the display 9 will display music information according to the progress of the music.
By inputting the color change signal output to
It is possible to match the progress of the song with the color changes in the lyrics.

〔Effect of the invention〕

As described above, the karaoke system of the present invention digitally encodes the information of most of the karaoke songs expected to be requested and stores it in a ROM with a large storage capacity so that it can be played back at any time. In addition to not requiring a huge amount of storage space, the requested song can be called up easily and quickly by inputting a keyword such as the identification code or song title of the desired song using an input device.

In addition, new songs or songs that are not recorded in the ROM due to extremely low request frequency are transmitted and played from the host computer's database via public lines at any time.
Since they are stored in RAM at the same time, this system can cover all karaoke songs, reduce the number of times public lines are used, reduce costs, and prevent database calls from becoming concentrated over time. Ta.

Furthermore, this system directly reads the memory and eliminates mechanical components such as disk drives, so the entire terminal can be reliably shielded, preventing failures due to the intrusion of water droplets and moisture. Also, there is no chance of the tape stretching or damaging the disc, destroying the karaoke data. Furthermore, since the mechanical parts do not wear out, the maintenance effort can be simplified.
