Abstract
The invention provides a method for amplifying and displaying a menu font of a set top box of a digital television, which is characterized by comprising the following steps of: acquiring a character string of the font to the amplified; calculating the line number and column number of a new dot matrix according to the amplification multiple by extracting the line number and column number of the dot matrix of each character of the character string; and calling an OSD module function to dot and fill color for the line number and column number of the new dot matrix so as to amplify the character. The method can conveniently realize the function of amplifying and displaying the menu font of the set top box, a plurality of sets of font libraries are not needed to be designed and stored in the space of a flash memory FLASH. Therefore, the space of the flash memory FLASH is reduced.
Description
[technical field]
The present invention relates to a kind of digitlization terminal equipment field, especially a kind of menu font of set top box of digital television amplifies the method that shows.
[background technology]
Along with the popularization of digital TV set-top box, TV set-top box is popularized gradually.In the use of set-top box, the client claims to the size of each menu font or title etc. is needed to amplify and shows, needs the character library support of different fonts size this moment.A lot of producers adopt the pre-storing multiple sets font libraries of enlarged fonts; Import font then and amplify order; And amplify order according to described font and from described many cover character libraries, select a cover character library; According to selected character library, show the size of the font that needs amplify then.Reach font in this way and amplify purpose, but this mode takies bigger FLASH space owing to need deposit many cover character libraries.But because the FLASH space is limited, only deposit a kind of character library, want to show that the font of different sizes just is difficult to realize this moment.
[summary of the invention]
The technical problem to be solved in the present invention, be to provide a kind of menu font of set top box of digital television to amplify the method that shows, realized that menu font of set top box amplifies the function that shows, and need not design how the cover character libraries leave in the flash memory FLASH space, thus the space of reducing flash memory FLASH.
The present invention is achieved in that a kind of menu font of set top box of digital television amplifies the method that shows, it is characterized in that, may further comprise the steps:
Step 10, choose character, generate a font character library, and leave in the character library message file after the data transaction of the character boundary chosen being become the data of the discernible character boundary of set-top box, generate a character zone address mapping table with font size;
When step 20, set-top-box opening the font character library in the FLASH flash memory is called in internal memory;
Step 30, a font size options is set in menu, selects the font size that will be provided with for the user as required;
Step 40, obtain the character string of wanting enlarge font;
Step 50, by finding the data of respective symbols size in the character string in the character library of described character zone address mapping table in internal memory;
Step 60, the font size that is provided with by the user contrast with the data of described respective symbols size, and the multiplication factor of enlarge font is wanted in calculating;
The dot matrix line number and the columns of a character of step 70, the described character string of extraction, and line number, the columns of the dot matrix that calculating makes new advances according to multiplication factor;
Step 80, call the OSD functions of modules and get line number, the columns of the new dot matrix of character ready Fill Color, finish the amplification of this character;
Step 90, judging whether characters all in the character string all is exaggerated, do not continue step 70 to step 80, is then to finish.
The present invention has following advantage: can amplify the menu font of set top box size arbitrarily according to client's demand.Need not design many cover character libraries and leave in the flash memory FLASH space, thus the space of reducing flash memory FLASH.
[description of drawings]
Fig. 1 amplifies the method flow schematic diagram that shows for font of the present invention.
[embodiment]
The present invention is described further in conjunction with Fig. 1:
If to deposit the font size of font be No. 12 to character library in the former set-top box, existing its font is amplified to No. 18, specifically realize in the following manner:
Step 10, at first with the character library instrument definition to deposit font size and etc., the character that will have type matrix then generates the font character library of a 512K size (font size of record character library), the font in this moment this character library is exactly the font of set size.And leave in the character library message file after the data transaction of the character boundary chosen being become the data of the discernible character boundary of set-top box, generate a character zone address mapping table.
Step 20, then in set-top box flash memory FLASH, allocation space is used for depositing character library, and character library is write among the flash memory FLASH.
Step 30, when set-top-box opening when reading flash memory FLASH character library called in internal memory, a font size options is set in menu, select the font size that will be provided with for the user.
Step 40, obtain the character string that to amplify demonstration again.
Step 50, in character library, find the data of respective symbols by the character zone address mapping table.
Step 60, the font size that is provided with by the user again follow the font size of the data of respective symbols to contrast, and calculate the multiplication factor of wanting enlarge font, amplify now for No. 12 as the script font to be shown to font No. 18, and font is amplified 1.5 times so.
Step 70, obtain the dot matrix size of a character of character string then, calculate and amplify the back abscissa, the dot matrix of ordinate is the dot matrix of one 18 row 12 row as font originally, and the dot matrix after amplifying so is exactly the new dot matrix of one 27 row 18 row.
Step 80, call the OSD functions of modules again and get line number, the columns of the new dot matrix of character ready Fill Color, just finish the amplification of a character of character string this moment.
Step 90, obtain the dot matrix size of character late and then, calculate and amplify back abscissa, the dot matrix of ordinate, get Fill Color again ready, judge whether characters all in the character string all is exaggerated this moment, do not continue step 70 to step 80, is the amplification of then having finished font.
In a word, the present invention can amplify the menu font of set top box size arbitrarily according to client's demand.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
