Then, in a communication karaoke apparatus that transmits song data from the center side, a technique of reducing the data size for displaying lyrics is also proposed. With this kind of technology,
The font image data of the character to be displayed is stored in the terminal device side in advance, and the character code designating the font image data to be read is the lyrics data in the song data. Then, in order to reduce the amount of font image data stored in the terminal device side, a technique has been proposed in which font image data of a character that is not generally used is treated as external character font image data. That is, the external character font image data is not stored on the terminal device side, and the external character font image data is included in the music data as necessary and transmitted. Then, the terminal device receiving the song data stores the external character font image data included in the song data, and when the character code is read as the song data is reproduced, the character code corresponds to the external character font image data. If it is, the external character font image data is displayed.

[0003]

However, in such a conventional technique, when the character code corresponding to the font image data previously stored in the terminal device is read out, the registered font image is always registered. The data is displayed. Therefore, the character code in the lyrics data is
When the font image data registered in advance is supported, the registered font is always displayed, so that the lyrics display mode is fixed.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a lyrics display control device for karaoke, which has a high degree of freedom in the lyrics display mode.

The control unit 2 appropriately reads out music piece data from the music piece data memory 1 and performs various controls. The external character font buffer 3 is a buffer memory that stores external character font image data included in the music data. The registered font memory 4 is a memory for storing registered font image data registered in advance in the device. The registered font memory 4 stores in advance a plurality of types of font image data such as Gothic font and Mincho font. Here, the external character font image data is special font image data used when reproducing the music data stored in the music data memory 1. On the other hand, the registered font image data is general-purpose font image data. The font image data corresponds to one character code, and the font image data can be specified by the character code. The search unit 5 searches the font image data stored in the external character font buffer 3 or the registered font memory 4 under the control of the control unit 2, and the display control unit 6 displays the searched font image data on the monitor 7. It controls the output.

1-1-2. Structure of music data Here, FIG. 2 is a diagram showing a structure of music data used in the present embodiment. As shown in the figure, the song data includes font management data, music data, and lyrics data. The font management data is information about font image data when the music data is reproduced, and includes font designation information and external character font image data. The font designation information is data that designates which type of font image data of the plurality of types of font image data stored in the registered font memory 4 is to be used. The external character font image data is the font image data necessary for reproducing the music data. The music data is data necessary for playing a karaoke piece, and is, for example, MIDI (Musical).
Instrument Digital Interface) is created based on the standard. The lyrics data is configured to include a character code indicating a character displayed as lyrics.

1-2. Operation of First Embodiment Next, the operation of the first embodiment will be described with reference to the flowchart shown in FIG. First, the control unit 2 reads the font management data stored in the music data memory 1 and stores the external character font image data in the external character font buffer 3 (S101). Then, the control unit 2
When the process of storing the external character font image data is completed, the reproduction of the song data is started, and the character code in the lyrics data stored in the song data memory 1 is read (S10).
2). Next, the font image data corresponding to the character code read in step S102 is searched from the external character font buffer 3 (S103). Then, it is determined whether or not the font image data corresponding to the character code read in step S102 is stored in the external character font buffer 3 (S104), and when it is determined that it is stored (S104; YES), The retrieved font image data is supplied to the display control unit 6,
The display control unit 6 outputs the supplied font image data to the monitor 7 (S105).

On the other hand, in the determination of step S104,
When it is determined that the font image data corresponding to the character code read in step S102 is not stored in the external character font buffer 3 (S104; N).
O), next, the font image data corresponding to the character code is retrieved from the registered font memory 4 (S10).
6). Here, when searching the registered font memory 4,
The font designating data stored in the music data memory 1 is read, and the font image data of the type designated by the font designating data is searched from the plural types of font image data stored in the registered font memory 4. Then, the retrieved font image data is supplied to the display control unit 6. The display control unit 6 outputs the supplied font image data to the monitor 7 (S1).
05). In this way, from step S102 to step S
In the process of circulating the process of 106, the character codes stored in the music data memory 1 are sequentially read, and the font image data corresponding to the read character code is preferentially retrieved from the external character font buffer 3. Go.

1-3. Specific Example of First Embodiment Here, a specific example of the first embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 shows the registered font memory 4
And the contents of the external character buffer 3 after storing the external character font image data. In the example shown in FIG. 4, the font image data “戀” corresponding to the character code 0001 is the external character font image data. That is, the registered font memory 4 stores "love" as the font image data corresponding to the character code 0001, but the monitor 7 displays an external character to display "戀" instead of "love". As the font image data, the font image data "戀" corresponding to the character code 0001 is attached. In this case, when the reproduction of the song data is started and the character code 0001 is read out, the external character font buffer 3 is preferentially searched as described above (see FIG. 3: step S103), and therefore the character code 0001 is corresponded. Even though the registered font image data “love” is stored, the external character font image data “戀” is searched. Further, here, the font type of the external character font image data is designated by the font designation data. For example, if the font type of the external character font image is "Round Gothic", it is specified that the font image data of "Round Gothic" is searched even when searching the registered font memory. Then, FIG. 5 is a diagram showing lyrics displayed on the monitor 7 in this case. As indicated by C1 in the figure, the external character font image data "戀" is displayed on the monitor 7.

As described above, if the font management data is attached, even the song data having the character code corresponding to the font image data registered in advance can be easily displayed as the external character font image data. Will be able to. Therefore, it is possible to freely change the font display while using the music data created to be reproduced without using the external character font image data.

2. Second Embodiment Next, a second embodiment of the present invention will be described. 2-1. Configuration of Second Embodiment First, the configuration of the second embodiment will be described. The device configuration of the second embodiment is the same as the first embodiment described with reference to FIG.
Since it is the same as the device configuration of the embodiment, the description thereof is omitted.
Here, the structure of the song data of the second embodiment will be described. FIG. 6 is a diagram showing the structure of music data in the second embodiment. As shown in the figure, the song data in the second embodiment includes font management data, music data, and lyrics data. In the second embodiment, unlike the first embodiment, the font management data includes
Contains character code conversion data. The character code conversion data is data that specifies conversion of a specific character code in the lyrics data into another character code, and as shown in the figure, corresponds to the character code string IN in the lyrics data and the corresponding character code string IN. The table TB is composed of a character code string OUT for searching the external character font buffer 3. This character code conversion data is, for example, even if the character code (registered character code) for designating the font image data stored in advance in the registered font memory 4 is read, the character code for designating the external character font image data ( It is used when searching by converting to external character code. A specific example in such a case will be described later.

2-2. Operation of Second Embodiment Next, the operation of the second embodiment will be described. Figure 7
It is a flow chart which shows operation of a 2nd embodiment. First, the control unit 2 reads the font management data stored in the music data memory 1 and stores the external character font image data in the external character font buffer 3 (S20).
1). Then, when the process of storing the external character font image data is completed, the control unit 2 starts the reproduction of the music data and reads the character code in the lyrics data stored in the music data memory 1 (S202). Next, the character code conversion data stored in the song data memory 1 is read out,
It is determined whether the character code read in step S202 is data that requires code conversion (S20).
3). Here, referring to the table TB shown in FIG. 6, if the character code read in step S202 is in the character code string IN, it is determined that the data requires code conversion. In the determination of step S203,
When it is determined that the code conversion is necessary (S203;
YES), the character code read in step S202 is converted into the character code instructed by the character code conversion data (S104). That is, the control unit 2
The character code corresponding to the character code read in step S202 is read from the character code string OUT of the table TB shown in FIG. 6 and used as the character code for searching the external character font buffer 3. Then, the search unit 5 searches the external character buffer 3 for font image data corresponding to the converted character code (S205), and supplies the searched font image data to the display control unit 6. The display control unit 6 outputs the supplied font image data to the monitor 7 (S206).

On the other hand, in the determination of step S203,
If it is determined that code conversion is not necessary (S203;
No), the process proceeds to step S207, and the font image data corresponding to the character code read in step S102 is searched from the registered font memory 4 (S207). Next, the search unit 5 supplies the searched font image data to the display control unit 6, and the display control unit 6
Outputs the supplied font image data to the monitor 7 (S206). Here, when searching the registered font memory 4, the font designation data in the song data stored in the song data memory 1 is read, and from the plural types of font image data stored in the registered font memory 4, Search for font image data of the type specified by the font specification data. When the process of step S206 is completed, the process proceeds to step S202, and the character code to be displayed next is set to the song data memory 1
Is read from (S202). In this way, step S2
In the process of circulating the processing from 02 to step S207, the character codes stored in the music data memory 1 are sequentially read, and the font image data corresponding to the read character codes are output to the monitor 7.

As described above, also in the second embodiment, it is possible to freely change the font display while using the music data created to be reproduced without using the external character font image data. Like

2-3. Specific Example of Second Embodiment Here, a specific example of the second embodiment will be described with reference to FIGS. 6 to 9. FIG. 8 is a diagram showing the contents of the registered font memory 4 and the contents of the external character buffer 3 after storing the external character font image data. In the example shown in FIG. 8, font image data (image data of star marks) corresponding to the character code 1111 is included in the song data as external character font image data. The registered font memory 4 stores registered font image data "star" corresponding to the character code 0002. However, the character code conversion data indicates that the character code 0002 in the lyrics data should be converted to the character code 1111 for retrieval (see TB shown in FIG. 6). By this, the character code 000 from the lyrics data
When 2 is read, not the registered font image data “star” but the external character font image data (image data of star-shaped mark) is searched. Then, FIG. 9 is a diagram showing lyrics displayed on the monitor 7 in this case. As indicated by C2 in the figure, the external character font image data (image data of star marks) is displayed on the monitor 7.

3. Modifications The present invention is not limited to the above-described embodiments, and various modifications as described below are possible.

For example, an operating means may be provided to switch the font type by user operation. Further, only in the case of the title, the lyricist and the composer, the external character font image data may be used, or the display may be changed for each division such as No. 1, No. 2 and the like. in this case,
The font management data may include information indicating the correspondence between the song section and the character code conversion.

The external character font image data may be directly inserted into the lyrics data. For example, when it is desired to output only one of the plural character codes existing in the music as the external character font image data, the external character font image data is directly inserted after the character code at that position. The control unit 2 that has read the character code and the external character font image data controls the search unit 5 to directly supply the read external character font image data to the display control unit 6 without searching the font image data. .

In the above embodiment, the registered font memory 4
Although a plurality of types of registered font image data are stored in, the external character font buffer 3 may also store a plurality of types of external character font image data. In this case, it suffices to be able to select which type of external character font image data is to be searched. The selection may be performed by a user operation, or the control unit 2 may randomly select. Here, as multiple types of external character font image data,
For example, it may be a special typeface such as a so-called circle character or a brush-written character.

Further, when the external character font image data is displayed instead of the registered font image data stored in the registered font memory 4 as in the above-mentioned embodiment, the symbols or characters whose meaning is unknown are used as the external character font image data. , If it is displayed instead of the registered font image data, the user cannot sing unless the lyrics are remembered, and the game is enhanced. Such replacement of font image data may be performed randomly, or may be performed according to a certain regular algorithm.
