BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling multi-subtitle playback of DivX video. For example, a DivX video file based on the MPEG-4 system and a different language associated with the video file are described. A multi-subtitle reproduction control method of controlling reproduction of multi-subtitle files.

In general, video files of DivX-Video, which are widely distributed through a network such as the Internet, are based on MPEG-4 format, unlike DVD video files based on MPEG-2 format. Since the video data is encoded and decoded, higher quality moving picture video processing is possible.

Meanwhile, an DivX-Video Player is developed for playing an optical disc on which a video file of the DivX video as described above is recorded, for example, a DivX video file recorded on a CD or a DVD. It is expected to be released and commercialized.

In addition, as shown in FIG. 1, the Divix video player includes an optical pickup 10, an RF processor 12, a digital signal processor 13, a Divix decoder 14, a microcomputer 15, and an OSD generator. (16), and the memory 17 and the like can be configured to include.

In the DivX video file system structure, as shown in FIG. 2, one video file and one subtitle file related to the video file are cooperatively recorded in each folder. For example, a video file called 'Matrix.avi' is recorded in a folder together with a subtitle file called 'Matrix.smi' having the same file name and different extension, and a video file called 'Niceguy.avi' is called 'Niceguy'. A subtitle file called '.smi' and a video file called 'Skyblue.avi', together with a subtitle file called 'Skyblue.smi', have a structure of being recorded in each folder.

That is, in the file system structure of DivX video, one movie file and one subtitle file (1 Movie File & 1 Subtitle File) are recorded in the folder with the same file name.

On the other hand, in the microcomputer 15, when the optical disc 10 is inserted and seated in the device, navigation information and a file system recorded in a specific area such as a lead-in area of the optical disc, etc. A series of download operations for searching and reading information and storing the information in the memory 17 are performed.

In response to a user's request, when reading and playing any one video file, the file system information stored in the memory 17 is searched and referenced, and after comparing and selecting subtitle files matching the video file name, The video file and the subtitle file are played together.

Accordingly, the user can watch a high-definition video image of a video file he wants and a subtitle video of a subtitle file linked to the video file.

However, in the file system structure of the general DivX video as described above, only one subtitle is cooperatively recorded in one video file, and in the DivX video player, the subtitle file having the same file name as the video file selected by the user. Since the user selects and plays back, there is a problem in that the user views only subtitle images produced in one specific language.

In addition, in order to allow a user to select and view subtitle images of different languages, a plurality of subtitle files in which subtitles of each language are recorded must be recorded. Thus, the same file name corresponding to one or more subtitle files in one-to-one correspondence. There is a problem that must record each of the video files.

Accordingly, the present invention was created to solve the above problems, and in the file system structure of DivX-Video, one video file and a plurality of subtitle files are linked and recorded, and the subtitle file name is Only a part of the video file name is the same, and the remaining part is recorded differently with a predetermined identification character that can identify the language of each subtitle, and also in a device such as a Divix video player, a number of parts of which match the video file name requested to be played An object of the present invention is to provide a multi-subtitle playback control method of Divix video for allowing a user to select and reproduce a subtitle file of a desired language by comparing and searching the subtitle files of.

According to an aspect of the present invention, there is provided a method for controlling a multi-subtitle playback of a Divix video, the method comprising: displaying a video file list by searching and searching file system information of a DivX video; Identifying a video file of the video file list selected by the user, and displaying a multi-subtitle file list associated with the video file; And selecting, by the user, the subtitle file selected by the user among the multi-subtitle file list, and selecting and playing the selected subtitle file together with the video file. As a result, when there is one subtitle file recorded in association with the video file, the method further comprises reproducing the video file and the subtitle file together while omitting an operation of displaying a list of subtitle files. A method for controlling multi-subtitle playback of Divix video. It features.

Hereinafter, a preferred embodiment of a multi-subtitle playback control method of Divix video according to the present invention will be described in detail with reference to the accompanying drawings.

First, a recording medium on which multiple subtitles of a DivX video according to the present invention is recorded includes a motion picture file (* .avi) and a multi-subtitle file (* .smi) of DivX video based on MPEG-4. It may be an optical disk such as a CD or a DVD, or various types of recording media such as a hard disk (HDD), which is a large capacity recording medium.

Meanwhile, in the file system structure of Divix video according to the present invention, a plurality of subtitle files may be cooperatively recorded in one video file, and in the plurality of subtitle files, different languages may be used. Subtitle images may be recorded.

The plurality of subtitle files are multi-subtitle files respectively associated with one video file, and are recorded and managed together with the video file in each folder, and have the same file name as a part of the video file, and the rest other than those. The portions are recorded differently with different file names, and the remaining portions different from the file names of the moving image file are separated by predetermined identification characters that can distinguish the language subtitles recorded in each subtitle file.

For example, as shown in FIG. 3, a video file called 'Matrix.avi' is one, along with multiple subtitle files called 'Matrix_eng.smi', 'Matrix_kor.smi', and 'Matrix_jpn.smi'. In the subtitle file, 'eng' represents English, 'kor' represents Korean, and 'jpn' represents Japanese.

In addition, a video file called 'Niceguy.avi' may be associated with a single subtitle file called 'Niceguy.smi', and a video file called 'Skyblue.avi' may be referred to as 'Skyblue_eng.smi' or 'Skyblue_kor.smi'. ', And' Skyblue_gem.smi 'can be linked and recorded in a single folder, with' eng 'representing English,' kor 'representing Korean, and' gem 'representing German Indicates.

4 is a flowchart illustrating a method for controlling multi-subtitle playback of a DivX video according to the present invention. For example, the present invention may be applied to a DivX video player or the like configured as described above with reference to FIG. 1.

For example, in the microcomputer 15 After searching and confirming the file names of the moving picture files recorded in the respective folders among the file system information, the OSD generator 16 controls the operation to generate a file list of the moving picture files from the television and the TV. The same external connection device displays the screen as an OSD image (S13).

For example, as shown in FIG. 5, video file names such as 'Matrix', 'Niceguy', and 'Skyblue' are outputted and displayed as an OSD image of a file list that can be selected by a user. If the user selects and designates any one video file (S14), the subtitle files associated with the video file are searched (S15).

In addition, the microcomputer 15 operates and controls the OSD generating unit 16 to display a file list of the retrieved subtitle files through an external connection device such as a television (OSD). The screen is displayed as an image (S16).

For example, as shown in FIG. 6, when the user selects and selects a video file called 'Matrix', the microcomputer 15 includes a plurality of subtitle files recorded in association with the 'Matrix' video file. 'Matrix_eng.smi', 'Matrix_kor.smi', and 'Matrix_ jpn.smi' are displayed as OSD images of user selectable file list.

When the user selects a video file called 'Niceguy', the user searches for the subtitle recorded in association with the 'Niceguy' video file. In this case, since there is only one subtitle file called 'Niceguy.smi' The microcomputer 15 immediately performs a series of operations of playing the subtitle file in association with the video file.

On the other hand, when the user selects and designates any one subtitle file while the file list for the plurality of subtitle files is displayed (S17), the user-selected video file and the subtitle file are played in association with each other. For example, if the user selects the 'Matrix' video file and the 'Matrix_eng.smi' subtitle file, the high-definition video of the 'Matrix' video file and the 'Matrix_eng.smi' subtitle file You will be able to watch the English subtitles video together.

In addition, the microcomputer 15 may change and play an arbitrary subtitle file, for example, a 'Matrix_jpn.smi' subtitle file according to a user's request. In this case, 'Matrix' The high-definition video of the video file and the Japanese subtitle video of the 'Matrix_jpn.smi' subtitle file can be watched together.

When the user changes and plays the 'Matrix_kor.smi' subtitle file, the user can watch the high definition video of the 'Matrix' video file and the Korean subtitle file of the 'Matrix_kor.smi' subtitle file. In addition, the microcomputer 15 performs various arbitrary operations desired by the user (S19).
