The central processing means designates specific karaoke information and loads it. , And perform operations and processing. The calculated and processed information is input to a sequencer. The sequencer has a function of sequentially executing the information for music reproduction and lyrics display.

The pattern ROM of the character generation means holds various characters and symbols in the data, provides the characters and symbols corresponding to the lyrics information, and furthermore, the color table stores the expected plural colors as data, and the display background The colors are selected from this color table. In the character generation means, the character control device reads a character pattern and a background color corresponding to the pixel information stored in the video memory from the pattern ROM and the color table in response to an execution signal from the sequencer. It has the effect of converting In this character generator, the pattern RO
It has a function to convert the data content of M into a dot matrix and make it displayable on the display, and the video controller processes this content to display lyrics on the display and to respond to the progress of music playback. To change the color of the lyrics one by one or change the background color as appropriate.

The trigger signal mixed with the music information has the function of reporting the progress of music playback to the lyrics display portion and linking the music playback with the progress of lyrics.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in more detail with reference to a block diagram schematically showing a lyric display device. Reference numeral 1 denotes a host computer provided outside, which is connected to the present invention device by a public line. Reference numeral 2 denotes a communication device, which uses an interface for a digital line and a modem for an analog line. Reference numeral 3 denotes a central control device for calculating and processing the loaded karaoke information, and includes a storage element for storing the karaoke information together with the CPU and an input device for designating the karaoke information. Reference numeral 4 denotes a sequencer which sequentially outputs the processed music information of the karaoke information to a sound source such as a MIDI device, and outputs the lyrics information separately from the music information to a subsequent stage. Reference numeral 5 denotes a pattern ROM for storing a large number of patterns of kanji and symbols such as JIS first and second levels as data, 6 a color table for storing a plurality of color designation information as data, and 7 a character control device. The entire lyrics information stored in the video memory 8 is displayed on a display, which will be described later, and the progress of the lyrics and the change of the background color are controlled in accordance with the signal from the sequencer 4. Reference numeral 9 denotes a character generator for displaying the character information read from the pattern ROM 5 as a dot matrix on a display. Reference numeral 10 denotes a character pattern converted by the character generator on the display 11 or a character generator from the character controller 7. This is a video control device for controlling the display 11 by a signal. In the drawing, a single arrow indicates a signal controlled by karaoke information, a double arrow indicates a flow of data, and a single arrow 12 of the arrow from the sequencer 4 to the character control device 7 indicates music information. A trigger signal for controlling the progress of the lyrics by instructing the progress of the music reproduction toward the lyrics display and changing the background color, and a double arrow 13 indicates the data flow of the lyrics information. It is.

Next, the operation of the present embodiment will be described. First, the user operates the input device of the central control device 3 to call a desired karaoke using an identification code or the like. Then, the karaoke information is loaded from the host computer 1 through the public line and stored in the storage element. After this is calculated and processed by the CPU, the music information is transmitted to the MI via the sequencer 4.
Music is played back by the sound source unified with the DI device. The lyrics information is input to the character control device 7 via the sequencer 4 and stored in the video memory 8. The stored lyrics information is read out from the pattern ROM 5 for the designated lyrics (characters) prior to the reproduction of the music, converted into a dot matrix by the character generator 9, and then displayed on the display 11 via the video controller 10. Subsequently, when music playback is started, the sequencer 4 sequentially processes the music information. The music information includes a trigger signal indicating a part currently playing at a position corresponding to the music playback and the lyrics, and further, an appropriate signal. A trigger signal for changing the background color of the display 11 is mixed in the position, and this signal is sequentially input from the sequencer 4 to the character control device 7 as shown by an arrow 12. In this case, after the progress of the lyrics is processed by the video controller 10 via the character generator 9, the position of the lyrics corresponding to the music playback portion is indicated by an arrow, or the color of the finished lyrics is changed. Thus, the music reproduction and the display of the lyrics are linked. For the background color, the character control device 7
The color designation is read from the color table 6, and the background of the display 11 is appropriately changed based on this information.

In this way, even if the karaoke data is binary-coded and the music information and the lyrics information are stored in the same file, the music reproduction and the progress of the lyrics display are accurately linked.

In this embodiment, the database depends on an external host computer. However, even when the terminal device is equipped with, for example, an optical disk, a configuration in which the communication part in the figure is omitted is sufficient, and the same function can be exhibited. .

〔The invention's effect〕

According to the present invention, the display of the lyrics is advanced in synchronization with the trigger signal mixed with the music information, so that the music reproduction and the lyrics display can be reliably linked to each other. It was possible to provide a user-friendly karaoke apparatus by preventing the deviation.

In addition, since the music information is sequentially extracted and reproduced while controlling the timing, it is possible to start the reproduction even if the data is not completed up to the final part, thereby shortening the time until the start of the reproduction. .

Furthermore, since the karaoke information is divided into song information and lyrics information and the data of the built-in pattern ROM and color table are used when processing the lyrics information, the data amount of the lyrics information per unit is relatively small. To reduce the time it takes to load data,
The effects they bring are immense.
