BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a DVD player driving technology, and more particularly, to audio in a DVD player capable of complex playback of an image file (such as a Joint Photographic Coding Experts Group (JPG)) file and an audio file (such as an MP3 (MPEG Audio Layer-3)) file. The present invention relates to a complex file setting and playback method in a DVD player suitable for efficient playback in consideration of the association of a file and an image file.

In recent years, electronic devices such as DVD players and DVD combos have been widely used in general homes, and CD and CD-R / W media which have recorded audio and image files (for example, MP3 and JPG files) in combination have been used.

Conventional DVD players that play such CD and CD-RW media have the disadvantage of forcibly playing them individually without considering the association between MP3 files and JPG files.

That is, in the composite playback function of MP3 file and JPG file, it is usually necessary to play MP3 file and JPG file contained in the same folder or to play sequentially from the top folder. In this case, MP3 file matching JPG image There is a problem in that MP3 files that are put in the same folder or individually matched with image files must be recorded in order.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems of the prior art, and sets the same file name of an image file and an audio file associated with an image of the image file so that an audio file having the same file name as the image file is reproduced at any time. It is an object of the present invention to provide a method for setting and playing a composite file in a DVD player for automatically searching and playing files.

According to an embodiment of the present invention for achieving the above object, as a composite file setting method in a DVD player, when a predetermined disk is inserted into the DVD player, by loading an image file from the disk to display the image file list information Determining whether a user-specified file name is set when an image file is selected, and whether an audio file associated with the set image file is selected, and when the audio file is selected, a file name of the audio file with the same file name as the image file. It provides a method for setting a compound file in a DVD player comprising the step of setting and storing.

According to another embodiment for achieving the object of the present invention, there is provided a method for playing a composite file in a DVD player, comprising: determining whether an image file is selected when an arbitrary disc is inserted and a compound playback is performed; Searching for a file name of an audio file having the same file name as the selected image file if an image file is selected; and if an audio file having the same file name as the selected image file is detected, searching for the selected image file and an audio file name identical to the file name of the corresponding image file A composite playback method in a DVD player comprising the step of simultaneously playing an audio file having the same.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention. In the following embodiments, a JPG file is adopted as an image file and an MP3 file is adopted as an audio file.

1 is a schematic block diagram of a DVD player for performing the method according to the present invention. The key input unit 100, the control unit 102, the driving unit 104, the memory unit 106 and the playback unit 108 are shown. Include.

As illustrated in FIG. 1, the key input unit 100 may be provided in a DVD player or a remote controller as a means for generating a predetermined key signal according to a user's key input action.

The control unit 102 performs various modes of the DVD player, for example, a playback mode, a function setting mode, etc. according to the key signal provided from the key input unit 100 described above. In addition, the control unit 102 stores the file name information of the entire MP3 file and JPG file on the disk inserted through the drive unit 104, and then controls to automatically find and play the associated MP3 file when playing any JPG file Perform the function. In this case, the file names of the MP3 file and the JPG file may be stored in the storage space of the disk, but may be separately stored in the memory unit 106 connected to the control unit 102. When the file name is stored in the memory unit 106, the set file name may be loaded even when the disc is subsequently ejected and inserted again.

The driving unit 104 is a means for performing overall driving of the DVD player, and is composed of a servo and an optical pickup unit (not shown). Here, the optical pickup unit reads data from the inserted disc, and the servo performs a function of controlling tracking and focusing of the optical pickup unit, respectively. At this time, the disc information recognized by the drive unit 104 is provided to the control unit 102.

The reproduction unit 106 performs signal processing on the MP3 data and JPG data read out from the optical pickup unit provided in the driving unit 104 to display on the reproduction screen.

Hereinafter, with reference to the above-described configuration, with reference to the flowchart of Figures 2 and 3 attached to the combined playback process in the DVD player according to a preferred embodiment of the present invention will be described in detail.

First, Fig. 2 is a flowchart of a compound file setting process for composite reproduction according to the present invention.

First, when a predetermined disc is inserted into a DVD player, the control unit 102 loads a JPG file from the inserted disc and displays JPG file list information on the screen.

In this case, in step S200, the controller 102 determines whether an arbitrary JPG file is selected through the key input unit 100.

If any JPG file is selected, the controller 102 proceeds to step S202 and step S204 to determine whether a user-specified file name (eg, abc.JPG) is set and an MP3 file associated with the set JPG file is selected. .

If the MP3 file is selected, the controller 102 proceeds to step S206 and sets the file name of the MP3 file to the same file name as the above-described JPG file. That is, the file name is set to "abc.MP3".

The file name information of the set JPG and MP3 files is temporarily stored in the inserted disk or the memory unit 106 (S208).

3 is a flowchart illustrating a process of playing a JPG file and an MP3 file set in FIG. 2 as a complex playback process in a DVD player implemented according to a preferred embodiment of the present invention.

First, when composite playback of a DVD player is performed in step S300, the controller 102 proceeds to step S302 to determine whether an arbitrary JPG file is selected.

If any JPG file is selected, the control unit 102 proceeds to step S304 to search the disk or memory unit 106 for the file name of the MP3 file having the same file name as the JPG file.

If no MP3 file having the same file name as the selected JPG file is detected (S306), the controller 102 proceeds to step S308 so that only the selected JPG file is played, but an MP3 file having the same file name as the selected JPG file is reproduced. If detected, the process proceeds to step S310.

In step S310, the control unit 102 simultaneously plays back the selected JPG file and the MP3 file having the same MP3 file name as the file name of the JPG file.

This step S310 continues until the next JPG file is no longer selected (S312).

The embodiments of the present invention have been described in detail above, but the present invention is not limited to these embodiments, and various modifications may be made by those skilled in the art within the spirit and scope of the present invention described in the claims below.

 According to the present invention, if the file name of an audio file associated with an image file and an image of an image file is set to be the same, and subsequently a composite file to be played back is reproduced, an audio file having the same file name as the image file to be played back is automatically searched for. When the DVD data is copied or backed up, the trouble of putting files in the same folder or ordering them individually can be eliminated.
