BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for playing a Divix text file. For example, a video and audio data of a Divix (DVIX) file can be reproduced with high quality video and high quality audio, and the text data can be subtitled. The present invention relates to a method for playing a Divix text file in a digital device to be played back.

DIVX files, which are widely used in recent years, are designed to freely use MPEG-4 codec developed by Microsoft for streaming. This is a video file that manipulates and transforms MPEG-4, which was developed in 1999 for the purpose of providing real time.

Originally, the American distributor Circuit City developed and replaced the DVD (Digital Versatile Disc) for a fixed amount and was released for rental, but disappeared in 2001 due to opposition from DVD companies and civic groups.

Since then, Max Morice has been rapidly spreading around the world by manipulating Microsoft's MPEG-4 and creating the DIVX Codec, which adopts the MP3 format to minimize the soundtrack, on the Internet. .

It is currently being updated by hackers around the world who are engaged in intellectual property sharing campaigns. The video portion uses MPEG-4, and the audio portion uses MP3. Stereoscopic sound is possible, but illegal copies that are distributed without paying a copyright fee have been pointed out as problems, and mainly due to the production of DIVX files using movie premieres or commercial DVDs, unsealed movies are often available via the Internet. It is spread first.

On the other hand, in a digital device that plays back a DIVX file, since the text data of the DIVX file is decoded in an arbitrary national language selected by the user on the OSD menu, if the user does not set the language or sets it incorrectly, Subtitle images superimposed on the DIVX image are displayed in different national languages, or broken subtitle images are displayed.

Therefore, the present invention was created to solve the above problems. For example, after adding a unique language code to a DivX text file and recording the same, a digital device searches for and checks the corresponding language code. SUMMARY OF THE INVENTION An object of the present invention is to provide a method for playing a Divix text file for selecting and executing an arbitrary Codec program to be reproduced and outputted normally in a subtitle image of a native language suitable for the Divix text file.

In addition, the present invention, after recording the codec (codec) program unique to the Divix text file, by downloading and executing it in a digital device, the Divix text for normal playback of the subtitle video of the native language suitable for the Divix text file The purpose is to provide a file playback method.

Divix text file playback method according to the present invention for achieving the above object, step 1 of searching for and verifying a unique language code recorded in the Divix text file; Selecting one codec program corresponding to the identified language code among a plurality of codec programs stored in the device; And executing the selected codec program and reproducing the text data recorded in the Divix text file as a caption image of a corresponding language.

In addition, the method for playing a Divix text file according to the present invention comprises the steps of: reading a unique codec program recorded in the Divix text file and downloading it into a device; And executing the downloaded unique codec program and reproducing the text data recorded in the Divix text file as a caption image of a corresponding language.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a Divix text file playback method according to the present invention will be described in detail with reference to the accompanying drawings.

First, the method for playing a Divix text file according to the present invention may be applied to various types of digital devices capable of playing DIVX files. For example, the digital device may include a hard disk as shown in FIG. 1. 10, optical disc 11, optical pickup 12, playback system 13, audio decoder 14, video decoder 15, text decoder 16, microcomputer 17, memory 18, etc. This can be configured to include.

In addition, as shown in FIG. 2, the Divix text file to which the present invention is applied may be divided into a header area, a data area, a tag area, and the like. In the header area, management information about text data recorded in the data area is recorded, and in particular, a unique language code corresponding to the text data is recorded.

On the other hand, a unique language code recorded in the header area may be written instead in the tag area, as shown in FIG. 2, and the unique language code is, for example, an identification having a recording size of 1 byte or more. As the code, a unique language such as Korean (KOR), English (ENG), Japanese (JAP), or the like is shown.

In addition, the language codes managed as described above are recorded in association with a plurality of codec programs stored and managed in a flash memory 18 or the like, respectively, as shown in FIG. Indicates which language the codec program is suitable for decoding text data.

In addition, when the MICOM 17 plays a Divix text file stored in the storage such as the hard disk 10 or the optical disk 11 or the like at the request of a user, a header area of the Divix text file ( Or after checking the language code recorded in the tag area), selecting and executing a codec program that matches the language code, for example, a codec program of a text conversion table that matches the language code. The subtitle video of the native language suitable for the Divix text file is normally reproduced and output. This will be described in detail below.

4 is a flowchart illustrating a method for reproducing a DivX text file according to the present invention. For example, when the DivX file recorded in the hard disk 10 or the optical disk 11 is reproduced, the audio decoder is performed. In (14), the audio data of the Divix file read out by the reproduction system 13 is decoded and output in MP3 format, and the video decoder 15 converts the video data of the Divix file into MPEG-4 format. In this case, a series of audio and video playback operations are performed, which are decoded and reproduced.

In addition, the microcomputer 17 sets the Divix text file reproduction mode according to the present invention (S10), and as described above with reference to FIG. 2, in the header area (or tag region) of the Divix text file. When the recorded unique language code is searched for (S11), for example, when the language code is normally searched and confirmed (S12), any one codec program that matches the language code is the flash memory 18. In step S13, it is searched whether or not there exists.

When the codec program corresponding to the language code is normally searched as a result of the search (S14), the corresponding codec program is executed to decode the text data recorded in the data area of the DivX text file to generate a unique language. A series of reproducing operations for reproducing and outputting the subtitle video of the image is performed (S15).

On the other hand, in the microcomputer 17, a language code does not exist in the header area (or tag area) of the Divix text file, or a codec program corresponding to a unique language code does not exist in the flash memory 18. In this case, an error message is output and displayed (S16), so that the user can directly select and designate any one language, or execute any one codec program preset by the user, and write the data in the data area of the Divix text file. A series of playback operations are performed to decode text data.

In addition, since the microcomputer 17 performs any corresponding operation requested by the user (S17), the text data recorded in the Divix text file and the codec program for decoding the text data into the caption image are inconsistent. This makes it possible to effectively prevent abnormal output of the caption video.

5 illustrates an embodiment in which a unique codec program and identification information are recorded in a Divix text file to which the present invention is applied. For example, in another embodiment of the present invention, the data of the Divix text file is shown. Identification information for indicating that the codec program of the native language is additionally recorded in the first recording section of the (Data) area and that the codec program is included and recorded in the header area (for example, CP_Include_Flag = '1'). Will be recorded further.

In response to a user's request, the microcomputer 17 searches for the identification information recorded in the header area to reproduce the codec program of the native language recorded in the data area. After reading and downloading, the downloaded codec program is executed to reproduce and output the text data recorded in the data area as a caption video of a native language.

FIG. 6 shows an operation flowchart of another embodiment of a Divix text file playback method according to the present invention. As described above, the Divix file recorded on the hard disk 10 or the optical disk 11 is reproduced. In this case, the audio decoder 14 decodes and outputs the audio data of the Divix file read by the playback system 13 in MP3 format, and the video decoder 15 outputs the video data of the Divix file. It performs a series of audio and video playback operations to decode to MPEG-4 format to reproduce the output.

In addition, the microcomputer 17 sets the Divix text file playing mode according to the present invention (S30), and searches for the header area of the Divix text file as described above with reference to FIG. S31) For example, when identification information (CP_Include_Flag = 1) indicating whether or not to include a codec program of a native language is retrieved from the header area (S32), the microcomputer 17 stores the data of the Divix text file. The codec program recorded in the area is read out and downloaded to the flash memory 18 (S33).

When the above-described series of download operations are completed normally (S34), the downloaded codec program is executed to decode the text data recorded in the data area of the Divix text file, and reproduce and output the subtitle video of the native language. A series of playback operations is performed (S35).

On the other hand, in the microcomputer 17, a value indicating that identification information is not searched in the header area of the Divix text file or that the identification information is not recorded including a codec program of a native language (for example, CP_Include_Flag = ' 0 '), or if the codec program of the native language is not downloaded normally, an error message is outputted (S36) to allow the user to directly select an arbitrary language, or any preset by the user. A codec program is executed to perform a series of playback operations for decoding the text data recorded in the data area of the Divix text file.

In addition, since the microcomputer 17 performs any corresponding operation requested by the user (S37), the text data recorded in the Divix text file and the codec program for decoding the text data into the caption image are inconsistent. Thus, abnormal caption images can be prevented from being displayed abnormally efficiently, and even if a codec program of a native language is not stored in the device, the caption video can be downloaded and executed directly from the Divix text file.

Or more, preferred embodiments of the present invention described above, for the purpose of illustration, those skilled in the art, within the technical spirit and the technical scope of the present invention disclosed in the appended claims below, to further improve various other embodiments Changes, substitutions or additions will be possible.

The Divix text file reproduction method according to the present invention constructed and constructed as described above, for example, reproduces video and audio data of a Divix file with high quality video and high quality audio, and converts the text data into subtitle images. On the digital device to be played back, the unique language code recorded in the Divix text file is searched and checked, and an arbitrary codec program corresponding to the language code is selected and executed, or the Divix text file is executed. By downloading and executing the recorded unique codec program, the text data recorded in the Divix text file is reproduced as a caption video of the corresponding language, so that the caption video of the native language suitable for the Divix text file can be reproduced and outputted. Text data recorded in a Divix text file and the text data It is a very useful invention that the codec programs decoded on the image are inconsistent and can effectively prevent abnormal output of the caption video.
