ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an improved method and apparatus for displaying subtitles by a multination language human-machine interface, and more particularly, to an improved method and apparatus for displaying subtitles by a multination language human-machine interface that having small memory space occupation and conveniently for program maintenance.
2. Description of the Prior Art
FIG. 1
shows the technological flowchart for displaying the subtitle of multination language human-machine interface by the conventional monitors. First of all, the basic concept would be gradually setting up the string (step
110
) and the location of the string list (step
120
) for every different country, and then forming as a bitmap file (step
130
). Finally, the above bitmap file is transferred to 80c51xa assembly language, where the assembly language used by chips will be programmed (step
140
) and also provide the use of controlling program for the screen displaying control. Wherein the string been displayed on monitors is handled by the method of uniformly lining up to the left of the list.
Three sorts of different language subtitle, such as English, Germany and French, been displayed on monitors are shown in
FIGS. 2
,
3
and
4
respectively. The conventional method for displaying the synonymous string of the same list in those three figures, such as “SETUP” in English, “CONFIG.” in French, and “EINRICHT” in German, is firstly to edit the character strings of those three languages individually. Each character string will be uniformly lined up to the left of the list and drawn to its bitmap file, as well as transferred to its 80c51xa assembly language relatively. Therefore, there is a need to draw a relative bitmap file for every different country and for every different string list. Hence, at least two drawbacks have been introduced by the conventional method: (1) A huge bitmap file database for the strings consumes a large amount of the programmed memory; and (2) any addition or correction of a string in the list would result in a redraw of the relative bitmap file, hence making a hassle to the program maintenance. Consequently, an improved method and apparatus for displaying subtitles of multination language human-machine interface that substantially occupies smaller memory space and easy for program maintenance is provided.
SUMMARY OF THE INVENTION
An objective of the present invention is to transfer the requiring characters, figures, and symbols to a character database, that is provided to be called by a controlling program and been used in a combination in achieving the target of saving memory space. In another objective of the present invention, as referring to a same meaning of multination language strings in different lengths, and in accordance with the character number of the “string combination code of multination language”, the combination of the relative string length and the calling usage for the character database can be adjusted elastically. In a further objective of the present invention, a fixed information structure of strings makes maintenance and adjustment easier. In a last objective of the present invention, the controlling program and the information structure are easy to be adjusted while the microprocessor is been replaced.
The principle technological thoughts of the present invention are: (1) A country selection program is designed within the human-machine interface system, which is capable in transferring the subtitle into the relative different nation's language. (2) Characters used by many different nations' language, such as English, French, German, etc., are repeated in a great amount, this characteristic can be specified as to provide repeats in calling usage for the controlling program while building up the character database.
The present invention relates to a method and apparatus for displaying subtitles by a multination language human-machine interface. First of all, a character database is been edited, and in accordance with the character size to edit the bitmap file for each individual character. The bitmap file is then transferred to 80c51xa assembly language and stored in the character database. Then, the “string code”, the “string combination code”, and the “string combination code of multination language” of the controlling program are established, and the content of the character database is been called. During a practical usage, the desired string is been called by the controlling program, then carried out the language judgement of the exercising nation. Next, in accordance with the characters included in the desired string, extracting from the character database, drawing the string and showing on the screen eventually.
