Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is to digitally encode a karaoke song frequently requested and store it in a semiconductor ROM (hereinafter simply referred to as “ROM”). The present invention relates to a karaoke system in which a karaoke system is saved directly from a database of a host computer connected via a public line or saved in a semiconductor RAM (hereinafter simply referred to as "RAM") and then played back.

[Conventional technology]

A conventional karaoke apparatus reproduces a commercially available recording tape or video disk containing a karaoke song in advance on a tape deck, a video player, or the like, and outputs a voice sung along with the karaoke song along with the performance from a speaker. It is a thing.

[Problems to be solved by the invention]

However, the above-mentioned tapes and video discs can record at most 8 songs in the former and about 20 songs in the latter, so if you try to cover the karaoke songs published in the past, the number of turns will be huge, and if a new song is announced You have to buy tapes and disks one after another. Therefore, if the above-mentioned tapes and disks are to be arranged, not only is the expense increased, but also not only a lot of space is required for these storage places, but also
There was a problem that it took time to select karaoke songs.

In most cases, the above-mentioned karaoke apparatus is installed around the water in a restaurant, but since this apparatus inserts and removes tapes and disks, the entire apparatus cannot be hermetically sealed and scatters and enters. In addition to the possibility of failure due to the effects of water droplets and moisture, the tape is stretched due to the mechanical operation, the disk is damaged, or there is a lot of abrasion and maintenance is troublesome. Was.

The present invention eliminates the mechanical structure as much as possible and digitally encodes the karaoke song, lyrics, and search information of the karaoke song that is expected to be stored in the ROM, and stores the song not recorded in the ROM as a database in the host computer. Then, by downloading this to a RAM, it is intended to provide a karaoke system in which a favorite karaoke song can be reproduced at any time.

[Means for solving the problem]

The present invention provides a semiconductor ROM,
A karaoke apparatus for reproducing karaoke data including a semiconductor RAM, communication means, control means, and a reproduction apparatus is employed. The karaoke data is composed of MIDI standard music information, lyrics information, and search information. The semiconductor ROM stores karaoke data, the semiconductor RAM stores downloaded karaoke data, and the input device inputs search conditions. , The control unit performs the first to fourth processes. Then, the first processing is to search the search information of the karaoke data of the semiconductor ROM according to the input search condition, and to the fourth processing if the search condition is satisfied, and to the second processing if not. Go on, second
Is to search the karaoke data search information in the semiconductor RAM according to the input search condition. If the search condition is satisfied, the process proceeds to the fourth process. If not, the process proceeds to the third process. Is to access the host computer to the communication means, download the karaoke data matching the search condition to the semiconductor RAM, and proceed to the fourth process. The fourth process reproduces the music information of the karaoke data matching the search condition. Each means is used to cause the apparatus to reproduce and display lyrics information on a display.

[Action]

When a search condition of a desired karaoke song, for example, an identification code is input by an input device, a memory search device is operated through the CPU to search whether or not the identification code is stored in the ROM. The entire karaoke data with the code is read and processed by the CPU. If the above identification code is not stored in ROM,
The karaoke data with the identification code is input to the CPU for processing if it is stored. Further, if the identification code is not in the RAM, the CPU determines this and immediately searches the host computer database through the public line to transmit the karaoke data with the identification code to the CPU, Is written to RAM and saved.

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

〔Example〕

Hereinafter, the structure of the present invention will be described more specifically based on one embodiment. In FIG.
With a ROM board, the data capacity can be increased to about 200 MB (megabytes), and karaoke data of an average of 80 KB (kilobytes) can be input for about 2000 songs. The above-mentioned karaoke data includes song information obtained by digitally encoding a karaoke song to be requested according to the MIDI standard, lyrics information in which lyrics are displayed in characters, song title, singer, composer and lyricist. And the like as keywords and search information using unique codes as identification codes. Numeral 2 is a semiconductor RAM in which the karaoke data can be written or read at any time within a range of about 30 songs. A backup battery 3 is added to the RAM so that the stored contents are not erased even when the power is turned off. It was made.

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

Reference numeral 4 denotes a memory search device for reading desired karaoke data from the ROM1 and RAM2, and reference numeral 5 denotes a CPU for controlling the memory search device, which processes the searched karaoke data for one or more songs. Reference numeral 6 denotes a host computer, which is a database of new songs published after the creation of the ROM 1 or karaoke songs that are rarely used and are not stored in the ROM 1, and are connected to the CPU 5 via a modem and a public line 7 such as a telephone line. It was done.

When ISDN is used as a public line, an interface is used instead of the modem because digital communication can be performed directly.

Further, 8 is an input device such as a keyboard for inputting conditions (identification code, keyword, etc.) for searching for a desired karaoke song, 9 is a display for displaying lyrics information of karaoke data in characters, and 10 is a reproducing device. Of the karaoke data input to the CPU 5 by the sequencer 11, the 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. The music is reproduced as a karaoke song by the speaker 14.

Next, the operation of the karaoke system will be described with reference to the flowchart shown in FIG. 2. If a search condition of a requested song, for example, an identification code consisting of a symbol previously assigned to all karaoke songs, is inputted by using the keyboard 8, When the CPU 5 controls the memory search device 4 to search the ROM 1 and finds the identification code from the ROM 1 (YES), the entire karaoke data with the identification code is taken out, and
Process with U5. The lyrics information is displayed on the display 9 in characters. On the other hand, the music information is output to the synthesizer 12 by the sequencer 11 as programmed as a MIDI signal, where it is converted to an analog signal, output to the amplifier 13 and amplified, and further reproduced as a karaoke music through the speaker 14. You.

If the identification code input to the CPU 5 is not in the ROM 1 (NO), the RAM 2 is searched. If the identification code is found here (YES), the character information and the music information are displayed by the above-described operation. ·Reproduce.

If it is determined that the identification code is not present in both the ROM and the RAM, the CPU 5 immediately searches the database of the host computer through the public line 7 and transmits the karaoke data with the identification code to the CPU 5. The transmitted karaoke data is written to the RAM 2 and saved, while the lyrics are displayed on the display 9 by the above-described operation.
, And the music is reproduced from the speaker 14. In this case, if the capacity limit of 30 songs has already been registered in the RAM2 and there is no free area, songs with a small number of requests and the oldest registration date are deleted in advance so that the storage capacity has a margin. .

As a method of selecting a desired karaoke, in addition to inputting the identification code in the above example, a method of directly inputting a keyword such as a song name using the keyboard 8 and searching for the song name from search information is considered. According to the method of inputting, the name of a singer or a composer given as file information is entered into the keyboard 8 and the related song names are numbered and displayed once on the display 9 once.
The function of searching for karaoke songs is improved, for example, the user can easily select a song by reentering the desired song number.

As means for displaying the lyrics of the karaoke, the entire lyrics are collectively displayed on the display 9 and the color of the lyrics is changed in accordance with the progress of the song, or the lyrics corresponding to the progressing song are displayed in one or two lines. There is a method of displaying each one. In this case, by inputting a color change signal output to the display 9 in accordance with the progress of the music in the music information in advance, the progress of the music can be made to correspond to the color change of the lyrics.

〔The invention's effect〕

As described above, the karaoke system of the present invention digitally encodes information of most karaoke songs for which requests are expected, stores the information in a ROM having a large storage capacity, and can reproduce the information at any time. In addition to the need for an enormous storage space as in the above, the requested music can be called up easily and quickly by inputting an identification code of the desired music or a keyword such as a music title using the input device.

In addition, new songs or songs whose request frequency is extremely low and not recorded in the ROM are transmitted and played back from the host computer database through the public line at any time,
At the same time, the data is stored in RAM, so this system can cover all karaoke songs, reduce the number of times the public line is used, reduce costs, and prevent the centralization of database calls over time. Was.

Further, since the present system directly reads the memory and eliminates the mechanical configuration of the disk drive or the like, the entire terminal can be reliably shielded, and a failure due to intrusion of water droplets or moisture can be prevented. Also, there is no tape expansion or damage to the karaoke data by damaging the disk. Further, since the mechanical parts are not worn, the maintenance work can be simplified.
