The present invention relates to a method for controlling playback of a digital multimedia file, and for example, to control playback of audio and video data based on text data included in a digital multimedia file such as a Divix file. The present invention relates to a playback control method of a digital multimedia file.

Recently, various types of digital multimedia files have been widely used and used. For example, DIVX files distributed through the Internet, etc., are MPEG-4 codec developed exclusively for Microsoft's streaming. It is a file created so that it can be used freely. It refers to a video file that has been manipulated and modified by MPEG-4, which was developed in 1999 for the purpose of providing voice, video, and animation in real time on the Internet.

On the other hand, such a Divix file is composed of an audio and video file (A / V File) and a text file (Text File), for example, the text file is edited and produced in subtitle files of various languages In a digital multimedia device, when playing a Divix file stored in a storage such as an optical disk or a hard disk, the text file included in the Divix file is selectively read and downloaded to a memory.

Then, the audio and video files configured in the Divix file are read out and reproduced in real time, and the text file downloaded to the memory is cooperatively reproduced so that the subtitle characters of the text data are interrelated with the audio and video data of the audio and video data. To be displayed.

Meanwhile, in various types of digital multimedia files such as the DivX file, playback grade information such as parental level may be recorded and managed. In the digital multimedia apparatus, the parental level recorded in the digital multimedia file is recorded. After detecting and confirming the value, the value is compared with a reference parental level value preset by the user.

When the detected parental level value is equal to or greater than the reference parental level value as a result of the comparison, children or teenagers may not play adult movies without playing the digital multimedia file. Do not play and watch.

However, in the general digital multimedia apparatus, since the reproduction operation for the entire digital multimedia file is controlled according to the reproduction grade information such as the parental level, for example, when adult images are partially distributed and recorded in the file, Since it is impossible to skip playback by selecting only the corresponding part, there is a need for an efficient solution for this.

Accordingly, the present invention has been made in view of the above problems and circumstances, and for example, a text file included in a digital multimedia file such as a DivX file, and playback grade information such as a parental level is added to a tag of text data ( In the case of additionally recording with Tag) information and co-reproducing the text file and the audio and video file, the text data of a predetermined unit to be displayed for a predetermined time by referring to the reproduction grade information additionally recorded as the tag information of the text data. Another object of the present invention is to provide a playback control method of a digital multimedia file for automatically skipping audio and video data associated therewith in a playback operation.

In accordance with an aspect of the present invention, there is provided a method for controlling playback of a digital multimedia file, the method comprising: retrieving and confirming playback grade information additionally recorded in the text file while playing the audio and video file in association with the text file; ; Comparing the checked reproduction grade information with reference reproduction grade information preset in the device; And three steps of selectively skipping a reproduction operation of text data of a predetermined unit and audio and video data linked thereto according to the comparison result.

Hereinafter, a preferred embodiment of a method for controlling reproduction of a digital multimedia file according to the present invention will be described in detail with reference to the accompanying drawings.

First, the method for controlling reproduction of a digital multimedia file according to the present invention can be applied to various types of digital multimedia devices. For example, as shown in FIG. 1, the digital multimedia device includes an optical disc 10, Optical pickup 11, VDP (Video Disc Play) system 12, hard disk 13, HDR (HDD Record) system, decoder 15, microcomputer 16, OSD generator 17, and memory 18 and the like can be configured to include.

Meanwhile, the microcomputer 16 outputs and displays an OSD menu screen for operating and controlling the OSD generation unit 17 according to a user's request so that the user can selectively input desired playback grade information. Thereafter, any one of reproduction grade information input through the menu screen, for example, a parental level value of 1 to 8 grades, is stored and managed in the memory 18 as a reference parallel level value.

In addition, when the microcomputer 16 plays a digital multimedia file recorded on the optical disk 10 or the hard disk 13, for example, a Divix file at the user's request, for example, When the DivX file recorded on the optical disc 10 is reproduced, the VDP system 12 is operated to selectively read out a text file corresponding to a subtitle character among the DivX files recorded on the optical disc 10. The memory 18 is downloaded to the memory 18.

For example, as shown in FIG. 2, an audio and video file (A / V file) and a text file (Text File) are recorded in the Divix file, and the text file according to the present invention is recorded for a predetermined time. Before and after the text data of a predetermined unit to be displayed, a parental level value is additionally recorded as tag information.

That is, as shown in FIG. 2, in case of text data called 'What a beautiful day', presentation start / end time information (eg, start = 100, end = 200) is recorded before and after the text data. In addition, a parental level value (for example, pl = 1) is additionally recorded.

In addition, in the case of the text data 'She has a sexy body', the presentation start / end time information (eg start = 700, end = 800) is recorded before and after the text data, and the parental level value is also recorded. (E.g., pl = 8) is additionally recorded, and the microcomputer 16 associates the text data with the text data with reference to the parental level value additionally recorded as tag information in the text data as described above. A series of operations for selectively reproducing the playback operation of the reproduced audio and video data is skipped.

FIG. 3 is a flowchart illustrating a method for controlling reproduction of a digital multimedia file according to the present invention. For example, in the microcomputer 16, the DivX recorded on the optical disc 10 in response to a user's request. When setting the playback mode for the file (S10), the operation of the VDP system 12 is controlled to read a text file included in the DivX file, and to perform a download operation for storing in the memory 18. (S11).

On the other hand, the microcomputer 16 operates the VDP system 12 to reproduce the text data stored in the memory 18 while reproducing audio and video data of the DivX file recorded on the optical disc 10. A series of DivX file reproduction operations for cooperative reproduction are performed (S12). For example, the audio and video data and the text data are cooperatively reproduced by presentation time information additionally recorded in the respective data. do.

As described above with reference to FIG. 2, the microcomputer 16 searches and confirms the parental level value additionally recorded as the reproduction grade information according to the present invention among tag information for each text unit to be displayed for a predetermined time. In operation S13, the reference memory 100 compares the reference parental level value preset in the memory 18.

Meanwhile, as a result of the comparison, when the searched and confirmed parental level value is equal to or greater than a preset reference parental level value (S14), the microcomputer 16 operates the VDP system 12 to control the corresponding text data. And the reproduction operation of the audio and video data associated with the text data is automatically skipped (S15).

For example, in a state in which the reference parallel level value 'pl = 8' is previously set in the memory 18, as described above with reference to FIG. 2, before and after the text data 'What a beautiful day' may be used. When the parental level value 'pl = 1' is additionally recorded, the microcomputer 16 operates the VDP system 12 to control the text data and audio and video data associated with the text data. Normally linked playback.

On the other hand, if the parental level value 'pl = 8' is additionally recorded before / after the text data 'She has a sexy body', the VDP system 12 is operated to control the corresponding text data, Playback of audio and video data associated with the text data is automatically skipped, and the above operation is repeated until the reproduction operation is stopped (S16).

When the reproduction operation is stopped, any corresponding operation requested by the user is performed (S17). As shown in FIG. 4, additional recording as tag information is performed before / after the text data to be displayed for a predetermined time. According to the determined parental level value, it is possible to select and skip playback of adult audio and video partially distributed and recorded in the Divix file.

Meanwhile, the parental level value additionally recorded as tag information before and after the text data may be additionally recorded in the text file together with any presentation time information without actually text data. In this case, the text data is not displayed during the time corresponding to the presentation time information.

However, since audio and video data to be co-played during the presentation time information is determined by the parental level value, the parental level value is additionally recorded as described above even in a section without text data. In this case, it is possible to partially limit the playback operation of the audio and video for the corresponding section.

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.
