Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a karaoke device that uses karaoke information as a database and plays music from the database, and for displaying or controlling lyrics on a display in accordance with the progress of music. The present invention relates to a lyrics display device.

[Conventional technology and its problems]

Generally, at karaoke, songs are played from speakers through an amplifier, and the lyrics corresponding to the songs are sequentially displayed on a display such as a CRT.Currently, however, these are played on PCs stored in compact discs, etc.
In most cases, the M signal is reproduced by an independent device, and in none of them is the M signal processed by encoded digital information.

By the way, in the present invention, a means is also planned to store binary-encoded lyrics information and music information as a database in the host 1 computer and download it over a public line, but this type of technology is not available in the past. 2. Description of the Related Art Means for transmitting visual information and auditory information using a videotex communication network is known. However, with this method, if you try to display or erase one part of one screen at a time, the rewriting speed of display and erasure will be slow, so if you do not rewrite the whole screen at a time. , unable to respond appropriately to the progression of the song. Therefore, there is a drawback in that it is not possible to appropriately erase only the lyrics or change the background color appropriately within one screen unit. Furthermore, since the speed of screen rewriting varies depending on the type of terminal on the user side, it is impossible to synchronize all terminals at a predetermined speed.

The present invention aims to solve such conventional problems, and in a configuration that stores and processes karaoke songs using binary codes, it is possible to store and process lyrics that are displayed on a display after the music has been played. To provide a lyrics display device for a karaoke display capable of erasing parts one by one, appropriately changing the background color of displayed lyrics, and allowing the progression of lyrics accurately corresponding to a song.

[Failure to solve the problem]

In order to achieve the above object, the present invention provides a central control unit (CPU) that calculates and processes specific karaoke information in a karaoke device whose data base is a plurality of karaoke information consisting of binary encoded music information and lyrics information. and,
A sequencer that sequentially plays music based on the information calculated and processed by the CPU and controls the display of lyrics on the display, a video memory that stores lyrics information for one song, and a video memory that stores the lyrics information for one song, and A character control device that controls the memory, a pattern ROM and a color table containing character and symbol patterns displayed on the display, such as kanji and symbols up to JIS level 2, and a plurality of expected background colors. ,
It consists of a character generator that converts arbitrary contents of the pattern ROM into a dot matrix on the display, and a video control device that controls the display, and the lyrics that are displayed on the display in response to music playback. We used a method of advancing the process and changing the background color as appropriate.

In addition, a method was used in which the song information was mixed with a trigger signal for displaying lyrics as the music progressed and for arbitrarily changing the background color.

[For production]

The database contains expected karaoke songs (usually several thousand songs)
The information obtained by binary encoding the songs and lyrics of is accumulated as karaoke information, and the central processing unit specifies specific karaoke information, loads it, and performs calculations and processing. Further, this calculated and processed information is input to a sequencer, and this sequencer has a function of sequentially executing the information for music reproduction and lyrics display.

The pattern ROM holds various characters and symbols as data, and provides characters and symbols that correspond to lyric information.Furthermore, the color table contains data of multiple expected colors, and the background color of the display is based on this color. selected from the table. In addition, the character control device reads the character pattern and background color corresponding to the lyrics information stored in the video memory from the pattern ROM and color table according to the execution signal from the sequencer, and converts the character pattern into a dosomatarisox by the character generator. It has the effect of causing The character generator has a function that converts the data content of the pattern ROM into a dot matrix and makes it displayable on the display.The video control device processes this content to display lyrics on the display and play music. It works by sequentially changing the color of the lyrics and changing the background color as appropriate in response to the progress of the song.

Further, the trigger signal has the function of communicating the progress status of music playback to the lyrics display section and linking the music playback and the progress of the lyrics.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in more detail with reference to a block diagram showing an outline of a lyric display device. Symbol 2 is a host computer installed externally, and is connected to the device of the present invention via a public line.

Reference numeral 2 denotes a communication device, and in the case of a digital line, an interface is used, and in the case of an analog line, a modem is used.

Reference numeral 3 denotes a central control unit for calculating and processing the loaded karaoke information, which includes a CPU, a memory element for storing karaoke information, and an input device for specifying karaoke information.

4 is a sequencer that sequentially outputs processed song information among the karaoke information to a sound source such as a MIDI device, and outputs lyrics information to a subsequent stage separately from the song information. 5, for example, many kanji characters such as JIS level 1 and level 2.
Pattern R that holds patterns such as symbols as data
OM, 6 is a color table that holds a plurality of color designation information as data, 7 is a character control device, which displays the entire lyric information stored in the video memory 8 on a display to be described later, and also corresponds to signals from the sequencer 4. This is used to control the progression of the lyrics and change the background color. 9
10 is a character generator for displaying the character information read from the pattern ROM 5 as a don't matrix on the display, and 10 is a character generator for displaying the character pattern converted by the character generator on the display 11, or for displaying the character information from the character control device 7. This is a video control device for controlling the display 11 using signals from the video controller. In the figure, one arrow indicates a signal controlled by karaoke information, and two arrows indicate a data flow. Of the arrows pointing from the sequencer 4 to the character control device 7, one arrow 12 indicates the music information. The two arrows 13 indicate the data flow of lyrics information, and the trigger signal is used to control the progress of the lyrics by instructing the lyrics display to control the progress of the music playback, or to change the background color. It is.

Next, the operation of this embodiment will be explained. First, the input device of the central control device 3 is operated to call up a desired karaoke using an identification code or the like. Karaoke information is then loaded from the host computer 1 through the public line and stored in the memory element. After this is calculated and processed by the CPU, the music information is transferred to M
Music is played using a unified sound source in the IDI device.

Lyrics information is also input to the character control device 7 via the sequencer 4 and stored in the video memory 8. This stored lyrics information is read out from the pattern ROM 5 by reading the designated lyrics (characters) before playing the music, converted into a dosoto matrix by the character generator 9, and then displayed on the display 11 via the video control device 10. . Subsequently, when music playback starts, the sequencer 4 processes the music information sequentially, and the music information includes a trigger signal indicating the currently playing part at the position where the music playback and the lyrics correspond, and an appropriate message. Display in position 11
Trigger signals for changing the background color of the characters are mixed, and these signals are sequentially input from the sequencer 4 to the character control device 7 as shown by an arrow 12. In this case, the progression of the lyrics is processed by the video control device 10 via the character generator 9, and then the position of the lyrics corresponding to the music playback portion is indicated with an arrow, or the color of the lyrics that has finished is changed. This links music playback and lyrics display. Regarding the background color, the character control device 7 reads the color designation from the color table 6, and the background of the display 11 is changed as appropriate based on this information.

In this way, even if karaoke data is binary encoded and music information and lyrics information are stored in the same file, the progress of music playback and lyrics display will be accurately linked.

In this embodiment, the database depended on an external host computer, but even if the terminal device is equipped with, for example, an optical disk, it is sufficient to omit the communication part in the figure, and the same functions can be achieved. I can cheat.

〔Effect of the invention〕

The present invention separates karaoke information into music information and lyrics information, and uses a built-in pattern ROM to process the lyrics information.
Since we decided to use data from the color table, the amount of lyrics information per unit is relatively small.
We were able to reduce the time required to load data.

In addition, since the lyrics display is progressed by a trigger signal mixed with the song information, music playback and lyrics display can be reliably linked, preventing discrepancies that occur when processing with different accuracy. The effects brought about by this are significant, such as being able to provide a karaoke device that is easy to use.
