BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character display device for displaying a character string supplied by a character code on a display device.

[0002]

2. Description of the Related Art Recently, a communication type karaoke apparatus, which can store many songs and can quickly introduce new songs, is becoming popular in place of a karaoke apparatus using a package medium such as a video disc. This communication-type karaoke device stores accompaniment data and lyrics data of many songs in a center, transmits the accompaniment data and lyrics data of the corresponding song to the requested terminal, and the accompaniment device on the terminal side. It plays music and displays lyrics.

The lyrics data transmitted from the center in this communication type karaoke apparatus is transmitted at the same time as accompaniment data with a character code having a small amount of data due to the limitation that it must be transmitted as fast as possible. Since has a strong entertainment element, there is a demand not only to display lyrics in a single order, but also to display various applications such as shaking ruby (kana).

In the conventional communication type karaoke apparatus, as shown in FIG. 5, when ruby is applied to a kanji whose lyrics are difficult to read, the character string of the ruby part is processed separately from the character string of the lyrics. . That is, the lyrics are displayed by designating the coordinate value (arrow a) of the beginning portion of the character string of the lyrics, and the character string of the ruby portion is the coordinate value of the leading portion ( It is displayed by designating the respective arrows b to e).

[0005]

In order to swing ruby in the conventional communication type karaoke apparatus, it is necessary to specify the display coordinate value for each block of ruby, and the amount of transmitted data is large.

[0006] Further, when considering displaying a chord name such as a guitar chord as one of the applications, the chord name transmitted from the center is displayed using an external character or the like by performing the same processing as that of ruby. You can However, if you change the pitch of the performance on the terminal to change the tonality of the music, or if you want to match the display with the code when you put a capo tasto on the guitar, you need to transpose the displayed code, but The display code could not be transposed by simply displaying the incoming character data.

Therefore, an object of the present invention is to provide a character display device that solves the above problems.

[0008]

As means for achieving the above object, a character string in which first character data and second character data distinguished from the first character data by a control character are mixed By detecting the control character from a center in which a large amount of data is accumulated and the predetermined character string data supplied from this center, the first character data is located at a specific position with respect to the character string composed of the first character data.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A character display device of the present invention is a center in which a large number of character string data in which first character data and second character data distinguished by the first character data and control characters are mixed are stored. By detecting a control character from the predetermined character string data supplied from this center, a plurality of terminals for laying out the second character data on the character string consisting of the first character data and outputting it to the display device can be obtained. It is configured. With this configuration, various applications can be displayed.

Some embodiments of the character display device of the present invention will be described with reference to the drawings.

First, as a first embodiment of the character display device of the present invention, lyrics display is displayed on the terminal side by rubbing ruby (with a kana in kana) on the kanji of a character string such as lyrics supplied from the center. The device will be described.

FIG. 1 is a block diagram showing a lyrics display device which is a first embodiment of the character display device of the present invention. In the communication type lyrics display device, many terminals are connected to one center, but in the figure, only one terminal is shown. In addition, when the lyrics display device is a communication type karaoke device, the structure is almost the same, and in addition to the functions of the terminal and the center shown in FIG. It can be realized by providing related functions.

In FIG. 1, the center 1 is provided with a music database 3 in which lyrics data of many songs are stored in the form of character codes, for example, and the lyrics data of the requested song is requested from the terminal 2. Send to terminal 2.

The terminal 2 includes a ruby information separating unit 4, a character expanding unit 5, font data 6, a character position calculating unit 7, a line layout unit 8, and a temporary storage unit 9. And center 1
The ruby information separating unit 4 detects the ruby control character in the lyrics data (character code) supplied from, and separates it into a character string indicating lyrics and a character string indicating ruby.

The character position calculation unit 7 calculates the start coordinate position of the character string indicating the lyrics based on the information supplied from the ruby information separation unit 4, and the number of ruby control characters and the number of ruby characters before the ruby. And are counted to calculate the display coordinate position of the ruby and output to the row layout section 8.

The character expanding unit 5 expands the character code supplied from the ruby information separating unit 4 into characters by referring to the font data 6, and outputs the characters to the line layout unit 8.

The line layout section 8 outputs the lyrics to the display device 10 while laying out the ruby at an appropriate position using the temporary storage section 9, and displays the ruby-sung lyrics.

With the above configuration, for example, when the character code indicating the lyrics as shown in FIG. 3 is supplied from the center 1, the display shown in FIG. 4 is displayed on the display device 10 connected to the terminal 2. It can be performed.

Among the character strings shown in FIG. 3, <ruby>
The part indicated by is a ruby control character and is a 1-byte code. Then, the ruby is supplied in the form of being sandwiched between the ruby control characters in the character code string indicating the lyrics, and by detecting this ruby control character, control for shaking the ruby is performed on the terminal 2 side.

The character (ruby) sandwiched between the ruby control characters is shaken on the character just before the ruby control character before the ruby, and n ruby control characters before the ruby are continuously supplied. In this case, the ruby is evenly allocated and displayed on the nth character before the character immediately before the ruby control character.

The size of the character used as ruby in FIG. 4 is about 1/4 of the size of the character displaying the lyrics itself. The position of the first character of the character string (display start coordinate of the character string: arrow a) is supplied from the center, but the display position of other characters and ruby in the middle of the character string is not specified, and the character position The display position is determined by the calculation unit 7.

Here, a specific process when the character code as shown in FIG. 3 is supplied from the center 1 to the terminal 2 and the lyrics as shown in FIG. 4 is displayed on the display device 10 will be described.

First, the kanji "heart" is displayed at the beginning position of the character string, and then the ruby control character <ruby> comes. Therefore, it is sandwiched by <ruby> on the kanji "heart". A small character "Kokoro" is displayed as ruby.

[0024] Then, after the character string "is cold night" is displayed, the small character "yo" sandwiched between <ruby> is placed on the character “night” which is the character just before <ruby>. Will be placed. Similarly, after the character string “fog” is displayed, “Kiri” and ruby are shaken on it.

[0025] Furthermore, after the character string "to one person" is displayed, two characters <Ruby> and two characters <Rubi> come after <Ruby>, so the two characters before <Ruby> The ruby “one person” is evenly assigned and displayed on top of “one person”. Finally, when the character string "TATAZUMU" is displayed, the character string as shown in FIG. 4 is displayed.

Here, when the ruby consisting of a plurality of (m) characters is evenly allocated and shaken on one or a plurality (n) of characters, the processing is performed by the number of ruby characters (m) and the distribution. The number of characters to be input (n) is calculated as input, or the start position of ruby and the interval between ruby characters are derived by referring to a table, and even allocation is performed for each number of characters. be able to.

FIG. 2 is a flow chart showing the above processing.
become that way.

First, it is judged whether or not the character code supplied from the center is a ruby control character (step 10).
1). If it is not a ruby control character (step 101 →
N) Since it is a character code indicating normal lyrics, the character corresponding to the character code is displayed as it is (step 11).
1). In the case of ruby control characters (step 101 → Y),
The number of ruby control characters is set to n = 1 (step 102), and it is determined whether or not the next character is a ruby control character (step 10).
3).

If it is a ruby control character (step 103 → Y), the number n of ruby control characters is increased by 1 (step 104), and it is further determined whether or not the next character is a ruby control character (step 103). , When the ruby control character continues, the number n of ruby control characters is increased. If it is not a ruby control character (step 103 → N), since it is a character code representing ruby, the number of characters of ruby is set to m = 1 (step 105), and the character code is stored (step 106). Since it is a character code representing ruby until it becomes a ruby control character, it is determined whether or not the next character is a ruby control character (step 107). If it is not a ruby control character (step 107 → N), ruby control character is displayed. Number of characters m is 1
(Step 108) and the character code is stored (step 106). This is repeated until it becomes a ruby control character. When it becomes a ruby control character (step 107 → Y), it indicates that the ruby part has ended, so m ruby characters are displayed above the last character displayed from the character indicating the last lyrics. Are evenly displayed and displayed (step 109). And until the end of the string
The above process is repeated (step 110).

As described above, in the present embodiment, by using the ruby control character, the ruby is also included in the character string for displaying the lyrics and transmitted. No need to process. In addition, since the character to be rubbed is determined by the number of consecutive ruby control characters, by counting this number and the number of ruby between the ruby control characters, ruby can be shaken at the correct position. Since it is not necessary to specify the display coordinate value for each ruby lump, the transmission data can be reduced. Further, even when it is desired to turn off the display of ruby, it is sufficient to control not to display the ruby between the ruby control characters on the terminal side, and the display / non-display can be easily switched.

Next, as a second embodiment of the character display device of the present invention, code data (chord data) is transmitted from the center together with a character code indicating the lyrics, and the code is transmitted together with the lyrics on the terminal side. A communication-type karaoke device that displays a chord name will be described with reference to the drawings.

FIG. 6 is a block diagram showing the outline of a communication type karaoke apparatus which is a second embodiment of the present invention. In an actual communication type karaoke device, many terminals are connected to one center, but in the figure, only one terminal is shown. Further, among the functions of the terminal and the center, only the parts related to the present invention are shown, and most of the functions related to performance and the like are omitted.

The center 21 is provided with a music database 23 in which a lot of music data including performance data and lyrics data relating to music is accumulated, and the music data of the music requested by the terminal 22 is transmitted to the requesting terminal 22. To do.

The terminal 22 comprises a data analysis section 24, lyrics generation section 25, font data 26, chord generation section 27, pitch change control section 28, chord change control section 29, line layout section 30, performance section 31 and the like. There is.

The data content of the music data supplied from the center 21 is analyzed by the data analysis unit 24,
It is sorted and output according to the type of data.

The lyrics generation section 25 refers to the font data 26, converts the lyrics data supplied from the data analysis section 24 into a character string, and outputs it to the line layout section 30.

The code generation unit 27 uses the font data 26.
With reference to, the code data supplied from the data analysis unit 24 is converted into a code name and output to the line layout unit 30. At this time, the output chord name may be changed (transposed) depending on the tonality supplied together with the chord data and the control signals supplied from the pitch change control unit 28 and the chord change control unit 29.

The line layout section 30 lays out the code name supplied from the code generation section 27 on the lyrics supplied from the lyrics generation section 25 and outputs it to the display device 32 for display. Here, when the chord display OFF is selected, only the lyrics supplied from the lyrics generation unit 25 are output, and when the chord display ON is selected, the y of the display position of each line of the character string for displaying the lyrics is y. The coordinates are modified so that the line spacing can be opened, and the code name is laid out and output between the opened lines. The performance section 31 generates and outputs accompaniment music from the performance data and the like supplied from the data analysis section 24. The pitch can be changed by a control signal supplied from the pitch change control unit 28.

The song data output from the center 21 to the terminal 22 includes at least lyrics data, chord data,
Contains tonality and performance data. Then, as performance data, MIDI (Musical Instrument Digital Inter
face) signal (standard MIDI file) is used, in addition to the MIDI event that stores performance information,
Since it includes a system exclusive event that can store free data and a meta event that stores information other than performance information, it is possible to send data indicating tonality in the meta event.

In the code data indicating the code name, a code control character (<code>), which is a 1-byte code, is described in the character code string that is the lyrics data, and then the code that indicates the code name. Describe the data. In this case, it is not necessary to reserve a special data area to display the code name. Since two or more pieces of code data are not continuously displayed, when the code data is fixed length data as described below, a code control character indicating the end of the code data is used. There is no need to use one code control character only at the beginning of the code data.

The code data supplied from the center 21 and the transposing process performed by the code generator 27 will now be described.

The chord data supplied from the center 21 is, for example, as shown in FIG. 7 (A), a 2-byte code consisting of a 6-bit chord type, a 5-bit bass tone, and a 5-bit chord tone. It is data, and by adopting a data structure as shown in FIG. 9A, it is possible to display a code name as shown in FIG. The transposition performed by the chord generation unit 27 is performed by the control signal supplied from the pitch change control unit 28 or the chord change control unit 29 with respect to the chord data supplied from the center 21.
From the actual tonality supplied by
The code name obtained as a result is displayed.

The karaoke apparatus often has a pitch change function capable of changing the pitch of the accompaniment music to a pitch that is easy for the singer to sing. This pitch change function
Normally, there is an operation button that can be adjusted in the range of -6 to +6, and the pitch of the tone can be changed in semitone steps. Therefore, the tonality display of the chord name needs to be transposed according to this pitch change. In the present embodiment, the pitch change control unit 28 sends a signal to the performance unit 31 to change the pitch of the accompaniment music and a control signal to the chord generation unit 27 to send a chord according to the amount of change in pitch change. The tonality display of the name is also changing.

When playing a guitar or the like, a simple chord may be played using a capo tasto. For example, when the actual chord is E ^b (E-flat), a capote is applied to the 3rd fret and the chord of C is sometimes played.
In this case, it is easier to understand if the C code is displayed instead of ^Eb . Therefore, in the present embodiment, a code change function (capo function) is provided on the terminal 2 side, and a frequency shift amount is designated by the operation button, so that a control signal is output from the code change control unit 29 to the code generation unit 27. , The display is shifted by a frequency with respect to the actual tonality.

Here, a concrete method of transposition performed by the control signal supplied from the pitch change control section 28 and the chord change control section 29 will be described with reference to FIG.

FIG. 8 is a diagram in which chord sounds are digitized in order, and the system of the chord is also shown.

The tonality (original tone) value supplied from the center 21 is added to both the value of the transposition amount supplied from the pitch change control section 28 and the chord change control section 29, and the remainder divided by 12 is transposed. The numerical value of the subsequent chord sound. At this time, whether sharp or flat is used is determined by adding the amount of transposition to the original tonality (however, in the case of minors, add 3 more) if the system shown in FIG. 8 is sharp or flat. It depends on the system.

Further, it is desired that the character strings of the lyrics displayed on the karaoke device display delimiter positions of the clauses at delicate intervals, but in the conventional character code, only full-width and half-width spaces can be designated. could not. Further, since the lyrics displayed on the display device use relatively large characters, the full-width space is rarely used, and it has been desired that the lyrics can be expressed at fine intervals less than the half-width space. Therefore, three types of 8 minutes empty space, 4 minutes empty space, and 2 minutes empty space (half-width space) are prepared, and an individual 1-byte code is assigned to each. Then, by using these spaces in combination as needed, it is possible to express the character string using various intervals.

[0049]

According to the character display device of the present invention, a large number of character string data in which the first character data and the second character data distinguished from the first character data by the control character are mixed are accumulated. The control character is detected from the center and the predetermined character string data supplied from the center, and the second character data is laid out at a specific position with respect to the character string including the first character data, and the display device is displayed. Since it is composed of a plurality of terminals for outputting to, the character string data such as lyrics can be additionally displayed on the terminal side only by transmitting the character code data from the center. In addition, this additional display / non-display switching process can be performed on the terminal side.

Then, the ruby control character is detected from the center in which a large number of character string data in which the character part and the ruby part are mixed and the predetermined character string data supplied from this center are detected, and the ruby part and the ruby part are detected. If it is composed of multiple terminals that output to the display device so that it can be displayed properly by separating it into parts, ruby can be shaken at the appropriate position simply by specifying the beginning part of the character string. .

Further, a center storing a large number of song data including at least lyrics data, chord data and tonality, and a plurality of predetermined song data supplied from this center, outputting plural lyrics and chord names to a display device. In the case of the terminal, the chord name can be displayed between the lines of the lyrics, and the song can be sung while playing with a guitar or the like. In addition, since the display of the chord name can be changed in response to a pitch change, chord change, etc., the chord name sent from the center can be changed and displayed according to the usage situation of the user. There is.
