The present invention relates to the processing of text data, and more particularly, to a method and apparatus for processing text data recorded on an information storage medium in accordance with attributes of the text data.

In an information storage medium storing text data, one text is made of text data encoded in various languages and stored in the information storage medium. The playback apparatus for reproducing the text data reads one of the text data encoded in various languages, renders it through a text generator, and displays the text data on the screen according to a user's selection. Therefore, the information storage medium storing the text data stores text data encoded in various languages, so that if the playback apparatus can process and display the text data created in these languages, it requires a lot of resources of the playback apparatus. Rather, it must separately store information about the languages that the playback device can process.

However, when the playback device is a consumer electronic device with limited resources, a language-only text generator supported by the home appliance is required.

Accordingly, a technical problem of the present invention is to classify a script defined by attribute information indicating how to process text data written in various languages by category, and the playback apparatus processes the text data according to the classified category. To provide a text data processing method and apparatus.

In addition, another technical problem to be solved by the present invention is to provide a playback apparatus for a specific language that processes text data more efficiently.

According to an aspect of the present invention, there is provided a method of processing text data, comprising: (a) extracting script category information classified according to a language attribute of text; And (b) rendering the text data according to the script information included in the extracted category.

The script category information includes a plurality of script information, and a script is preferably a plurality of Unicode symbols are bundled and processed as a unit, and the script is preferably a script used for representing a character set in Unicode.

In addition, the script category information preferably represents information about a language supported by the playback apparatus, and the script category information is particularly preferably stored as a system parameter of the playback apparatus.

On the other hand, according to another field of the present invention, the above technical problem, the text data is encoded in a plurality of languages; And script category information classified according to language attributes of the text data.

On the other hand, according to another field of the present invention, the above technical problem, an apparatus for processing text data, extracting unit for extracting the script category information classified according to the language attribute of the text; And a text generation unit that renders the text data according to the script information included in the extracted category.

On the other hand, according to another field of the present invention, the above technical problem, the text data storage unit for storing the text data encoded in a plurality of languages and the script category information classified according to the attribute of the language; And a text data processing unit which reads the text data and renders the text data in accordance with the script information included in the script category information.

On the other hand, according to another field of the present invention, the above technical problem, (a) extracting the script category information classified according to the language attribute of the text; And (b) rendering the text data according to the script information included in the extracted category on a computer readable recording medium having recorded thereon a program for executing the text data processing method on a computer. Is achieved by

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

FIG. 1A is a diagram for describing that a text generator processes and outputs text data.

Referring to FIG. 1A, it can be seen that the text generator receives text data and font data in order to render and output text data. For example, when the language of the text data is English and the font data uses Arial font, if the text generator processes the text data "Text Data (10-12)" using Arial font, "Text Data (10"). 110) is displayed on the screen. In this case, each component constituting the full text data, for example, '(', 'T', '1', '-', etc. is called a symbol, and depending on how the text data is processed, Scripts exist, for example, a "left to right" script is a script that displays text data from left to right, and an "Arabic" script is a script that means processing units of numbers or symbols at once. That is, the script may be included in the text generator of the playback apparatus in the form of a program describing a method of processing a plurality of symbols having the same attribute, so that the processing unit of the text data varies depending on the script information. Compared to the symbols of the symbol, the script does not apply to multiple symbols with the same property. It is.

In the example of FIG. 1A, text data is rendered in symbol units, and when a specific attribute value is not assigned at the time of manufacture of the text data storage medium, the English text data is a bidirectional attribute value as a "left to right" value. Since "Text Data (10-12)" 110 is output.

FIG. 1B is a diagram illustrating a text data output screen when the bidirectional attribute value is "right to left".

Since the text generator renders in symbols, each symbol is output one by one from right to left, and as shown in FIG. 1B, ") 21-01 (ataD txeT" 120 is output. However, alphabetic data can be processed symbolically, but numeric and symbolic data are not output correctly, so the text generator includes attribute information, or scripts, to correctly display symbols with the same attributes. It demonstrates with reference to 1c.

FIG. 1C is a diagram illustrating rendering text data when the text generator includes information that the "Arabic Script" can be processed to correctly display a bundle of numbers and symbols.

Referring to FIG. 1C, the text generator does not render text data in symbol units, but in script units. In this case, the text generator processes a bundle of numbers and symbols in units of bundles using information called "Arabic Script" and renders them. Accordingly, the word "(10-12)" including a number as shown in FIG. 1C is regarded as a symbol and correctly displayed as rendered, and "(10-12) ataD txeT" 130 is output.

FIG. 1D is a diagram illustrating a text data rendering result when information indicating that "Hebrew Script" can be processed is added.

That is, when the text generator can process information about "Hebrew Script", the numbers 10 and 12 are processed, respectively, so that they are displayed as "(12-10)" rather than as "(10-12)". As a result, "(12-10) ataD txeT" 140 is output.

As described above, when the text generator renders the text data, the text generator renders the data instead of the symbol unit. Therefore, in the present invention, when the text generator indicates specific language information that the text generator can process, text processing of the text generator is performed using category information generated by classifying the script based on the script information without using all the language information that consumes a lot of resources. Find out. In particular, in the case of the text generator using the script category information according to the present invention, the playback apparatus does not need to include all the script information related to all languages, so that the playback apparatus includes only the script information necessary for the specific local language to be supported by the playback apparatus. You can efficiently use limited resources. In other words, it is possible to provide a specific region-specific playback apparatus that supports only a specific region language more efficiently.

2A to 2B are diagrams showing an example of using a script as information representing a language code that can be processed by a text generator in a playback apparatus according to the present invention.

Referring to FIG. 2A, the conventional playback apparatus has language information 200 that can be processed by the playback apparatus for each language. For example, in Korean language, even text data made in Korean language may include English, numbers, symbols, and other Greek characters in the middle. Therefore, the system parameters of the playback apparatus must have attribute information, that is, script information, such as "Arabic", "Hangul", and "Greek" in order to process these various languages. As described above, even text data generally made in one language includes a plurality of script information of about 100 as described above, and thus requires a lot of resources of a playback device. In order to solve this problem, in the present invention, as shown in FIG. 2A, language codes having the same script information are divided into the same category 202.

As a script, a script used to represent a character set in Unicode is used. In the script using the character set in Unicode, there is a script as shown in Figure 2a. When the languages are divided by categories using the same script as described above, the information can be divided into about eight categories as shown in FIG. 2B, and the information indicating that the text generator of the playback apparatus can process at least one category. Is stored in the form of a system parameter. This way you can process all the scripts that fall into the category. Therefore, when an information storage medium storing text data made in a plurality of languages is played by the playback device, if a specific language is selected by the user, the playback device finds a script to use based on the Unicode value in which the text data is created. Then, it is determined by referring to category information stored in system parameters or the like whether the text generator in the playback apparatus can render the script.

In addition, since the script category information corresponding to the language supported by the playback apparatus is specified as a system parameter of the playback apparatus, the text generator included in the playback apparatus may include only the script information corresponding to the specified script category information 202. In addition, a playback device dedicated to a specific local language can be provided using less resources.

3 is a block diagram of a playback apparatus according to the present invention.

The text data processor 320 renders the text data. The text data may be recorded in an information storage medium or in a memory provided in the reproduction device. In FIG. 3, an information storage medium or memory in which text data is recorded is referred to as a text data storage unit 300.

The text data file produced in correspondence with the video being played and the font data to be used for rendering the text data are read from the text data storage unit 300 and stored in the buffer 310. The text data stored in the buffer is transferred to the text data processor 320 to parse information necessary for rendering the text. Subtitle text, font information, and rendering style information necessary for text rendering are also passed to the text data processing unit 320 to render the text data to generate a bitmap image, and to specify an output start time and an output completion time of each item of text. To generate the output data and transmit it to the presentation engine 330. Accordingly, the text data processor 320, the extractor 322 for extracting the script category information classified according to the language property of the text, and the text generator 324 for rendering the text data according to the script information included in the extracted category. It includes.

The presentation engine 330 combines the bitmap text data stored in the text data storage unit 300 and the text data rendered by the text data processing unit 320 to output to the display device.

4 is a flowchart of the text data processing method of the present invention.

Script category information classified according to the language attribute of the text is extracted (S410). It is determined whether the extracted script category is a processable script stored in a system parameter of the playback apparatus (S420), and if it corresponds to a processable script category, the text data is rendered according to the script information included in the extracted category. (S430). If the script category cannot be processed by the playback device, the text data cannot be processed, thus ending.

As described above, according to the present invention, as the language information that the text generator of the playback apparatus can process, the script category information classified by the script is stored and the text data is processed using this information, thereby wasting resources of the playback apparatus. Can be prevented.

In addition, by specifying the script category information corresponding to a specific local language that the playback apparatus should support as a system parameter of the playback apparatus, and including only the script information included in the designated category by the text generator of the playback apparatus, The playback apparatus can provide a text generator for a specific local language. [0026] Meanwhile, the above-described text data processing method can be created by a computer program. Codes and code segments constituting the program can be easily inferred by a computer programmer in the art. In addition, the program is stored in a computer readable media, and read and executed by a computer to implement a text data processing method. The information storage medium includes a magnetic recording medium, an optical recording medium, and a carrier wave medium.

So far I looked at the center of the preferred embodiment for the present invention. Those skilled in the art will appreciate that the present invention can be implemented in a modified form without departing from the essential features of the present invention. Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation.
