The present invention relates to a multi-code processing system and a method for generating a font image of a multi-code. More particularly, the present invention relates to a multi-code processing system and a font of an area division method, which is easily converted into a code system for use in each set. A multicode processing system for generating font images using a data pool and a method for generating font images of multicodes.

In general, an AV system or the like is provided with a device capable of playing an optical disc such as a DVD title, and subtitles of various languages are provided to the DVD title. These various language subtitles are stored in the optical disc of the DVD in the form of digital data by a constant character code system.

In general, in order to display characters on a digital device such as a PC or a mobile device, a character code system including one byte or two bytes corresponding to each character is provided. In the early character code system, one-byte character code system called ASCII code was mainly used. This ASCII code has a display limit of 256 characters because it displays characters in 1 byte. This display limit has no problem in English or Latin, but has been limited in displaying various characters such as Korean, Chinese, Japanese, and Arabic.

In addition, each country uses a one-byte or two-byte character code system, and the same one-byte character code corresponds to a different character from country to country, which causes a problem in that international data exchange is not smooth.

 To overcome this problem, a Unicode system that displays characters in two bytes, or 16 bits, was born. The Unicode system displays characters in 16-bit, which can correspond to 65,536 characters, which enables the global character code system to be unified by mapping all the characters of the world to one code system. However, in order to display the corresponding character, font data is needed to graphicize the character data to make the font image. High-end systems such as PCs do not have any problems, but in limited-performance systems such as AV systems, the capacity is large in view of memory and processing speed. There is a problem in that not all of the font data can be prepared.

In addition, until the emergence of the Unicode system, each country has used a separate character code system for processing characters in digital devices. High-capacity storage media such as DVD titles are basically provided with subtitles from various countries. The character code system must be processed and displayed. There has been a need for a processing system that processes this process simply and efficiently, and a method of generating font images under various character code systems.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to easily and efficiently convert various character code systems to character code systems used in each set, and to selectively utilize a large amount of font data, thereby enabling low specification. It is to make font image of character data of various character code system in system of.

A multi-code processing system of the present invention for achieving the above object is a character code data input unit for receiving text character code data; A preprocessor for converting the input character code data into a code system of the set when the input character code data is not a code system used in the set; And a post-processing unit for generating a font image by using the plurality of font data pools divided by character regions from the character code data transmitted from the pre-processing unit.

The character code data conversion may be determined by comparing a code parameter included in the input character code data with a set of code parameters.

In addition, the plurality of font data pools may be replaced or added to a font data pool of a predetermined region according to a set environment of use.

In addition, an ID is assigned to each of the plurality of font data pools, and using the ID as an index, the font data corresponding to the character code data transmitted from the preprocessing unit is found to create a font image.

In addition, the code system used in the set is characterized in that the Unicode system.

In accordance with another aspect of the present invention, there is provided a method of generating a font image of a multicode, receiving text character code data, comparing code parameters included in the input character code data with a set of code parameters, and If the code parameters are different in the comparison, the input character code data is converted into a set of code systems using a code conversion table, and a font image is generated using font data corresponding to the converted character code data. .

In addition, the font data is characterized by consisting of a plurality of font data pool (pool) divided into a predetermined area.

In addition, the plurality of blocked font data pools may be replaced or added to a font data pool of another predetermined area according to a use environment of a set.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

1 is a control block diagram of a multicode processing system according to the present invention. The multi-code processing system of the present invention determines which character code system is composed of the character code data input unit 100 and the input character code data for receiving the character code data of various character code systems, that is, a set. Pre-processing for converting a character code system to a set through a code conversion table 120 that defines a correspondence relationship between various character course systems and a code system used in a set when the character code system is not used in the The unit 110 is provided. The converted character data is cut into the basic units of the character code system of the set. For example, in the Unicode system, character data is divided into two bytes. The multi-code processing system of the present invention is characterized by processing by dividing the entire character code used in a set into a predetermined area, and the plurality of divided areas are given a unique ID. The character data divided into basic units is identified by which one of the plurality of divided regions is included, and the ID of the region including the character data is assigned to the character data, and the plurality of divided regions provided for each of the plurality of divided regions using the assigned ID. The font data pool 140 finds a corresponding font data pool and creates a font image by using font data corresponding to the character data, and when the graphic font image of all the character data is created, And a display device 150 for displaying to a user.

Referring to the operation of the multi-code processing system of the present invention by the above configuration, a character code system in various sets may be provided according to the environment in which the set is used. The case where the system is a Unicode system will be described as an example. In the set, character data by various code systems is input. One byte of character data, such as ASCII, may be input, or one + two bytes of character data, such as Shift JIS, may be input. If character data of different lengths is inputted, there may be confusion in the processing of character data, and the character data is converted into a 2-byte character code which is a basic unit of Unicode system. The input character data may include a code parameter indicating which character data is created under the code system. By comparing this code parameter with the code parameters of the set, the code parameter is bypassed to the post-processing unit 130 and the code conversion table ( 120) to set the code system. In this case, due to the limited performance of the set, data for conversion of all codes may not be provided. If conversion is impossible, ID_Invalid is assigned to the character data. The above operation is processed in the preprocessor 110. The processed text data is transferred to the post processor 130.

The post processor 130 receives the character data processed by the pre processor 110 and cuts the character data into two bytes, which are basic units of Unicode. It is determined whether the divided two-byte character data is included in the plurality of divided regions, and the ID of the included region is assigned to the character data. If no area is included or if character data cannot be converted previously, ID_Invalid is assigned. When the ID is assigned as described above, the font data pool corresponding to each ID is found by using the assigned ID as an index, and the font data corresponding to the character data is mapped to generate a graphic font image. The above operation is repeatedly performed until the last character data, and when a font image of the last character data is generated, it is sent to the display apparatus 150 for display.

2 is a control flowchart of a multi-code font image generation process according to the present invention. First, text character code data is input through the character code data input unit 100 (step S200). The character data may have a length of 1 byte, 1 + 2 bytes, or 2 bytes depending on the character code system used. Make it 2 bytes, the basic unit of Unicode. For example, the ASCII code has a length of 1 byte, and the 8-bit 0 is padded to the 2-byte code system (step S210). Comparing the code parameters and the code parameters of the set (step S220) and converts to the code system of the set by using the code conversion table 120 provided in the set (step S230), and bypasses the step S230 if the same. The above is performed in the preprocessor 110 as described above. The character data transferred from the preprocessing unit 110 determines how many total characters of the input character data are, and cuts the data into two bytes of Unicode units (step S240). In step S250, if there is an area including the divided character data, an ID of the corresponding area is assigned (step S260). Using the assigned ID as an index, the font data pool 140 corresponding to the ID is found in the font data pool 140 of the recovery provided in the set, and the font data corresponding to the character data is mapped and graphicized. Step S270) If the character data is not included in the area set in the set in step S250, the character is assigned to the character such as "*" or "#", which is assigned ID_Invalid and assigned to ID_Invalid in advance. The data is graphicized. (S280 and S290) The above steps S250 to S290 are repeated as many as the total number of characters of the inputted character data. (S300) Graphical font images of all the inputted character data are generated. After that, it is sent to the display device 150 to be displayed on a monitor or the like (S310).

3 is a table illustrating an example of a blocked font data pool according to the present invention. In the table of FIG. 3, IDs are assigned to each region in Unicode, which is divided into regions corresponding to ASCII, European codes, Japanese, and Korean completion forms. By dividing the data into certain areas and adding or replacing the corresponding areas according to the environment in which the set is used, an optimized multicode processing system can be created. For example, if a set is sold in Arabic, you can add Arabic instead of Korean and Japanese. In other words, ID3 and ID4 can be removed and new ID ID5 can be added as follows.

ID5: 0x0600 ~ 0x06FF

According to this, the font data is added only to this part and the existing Korean and Japanese font data are extracted and it becomes a multi-code processing system optimized for Arabic.

As described in detail above, the present invention can easily convert any code system that a user wants to use into a code system of a set and display the code system. The code system is divided into a predetermined area according to the environment or purpose for which the set is used. As it can be selectively used, multicode can be efficiently processed under a limited performance system.
