In operation 202, the controller 120 may include a feature table in the portable apparatus 10 that defines the information, that is, a DRM method / type, a codec, a format, a resolution, a compression ratio, an image format, a sentence format, and the like. It is determined whether the feature table as shown in FIG. 2 is provided in the portable device 10.

Therefore, when the feature table is provided in the portable device 10, the controller 120 reads the feature table provided in the portable device 10 (operation 204). Subsequently, the controller 120 checks supportable DRM information and playable content information with reference to the read information and searches for corresponding DRM information and content information (step 206).

If the search result can be converted, the control unit 120 transmits the content information of the selected data file to the conversion unit 130 to convert the content information of the selected data file into a codec / format that can be supported by the portable device 10. However, in step 208, when it is impossible to convert content information of the selected data, a guide message that is impossible to convert the DRM information and content information is output (step 209).

Subsequently, the conversion unit 130 decodes the DRM information of the data file by referring to the feature table (operation 210). In other words, in order to prevent the illegal copying and theft, the DRM information of which the DRM information is encrypted (converted to an arbitrary code sequence) is restored.

Then, the conversion unit 130 converts the content information from which the DRM information is restored and converts it into a codec / format supported by the portable device 10 (step 212). An embodiment of converting the content information codec / format of the data file is shown in FIG. 3.

That is, as shown in FIG. 3, the sound information (MP3, WMA, OGG) that is the content format / codec is converted into the same sound information (MP3, WMA, OGG), and the video information (AVI, ASF, MPG, MPEG, MP4, MOV) codec is converted to video information (AVI, MPEG4) codec. In addition, although the extension (JPG, BMP, GIF, PND), which is the content information format of the media file, is converted into the extension (JPG, BMP), this is not possible in one embodiment, and the content format (supported compression rate, document) may be changed by another method. Etc.) may be converted. Herein, when the file converted from the content information is a video file, the file is converted in consideration of the resolution and bit rate of the portable apparatus 10.

When the content codec / format is converted in the above-described manner, the conversion unit 130 encrypts the downloaded data codec / format in order to prevent illegal copying and theft of the converted data file (step 214, 216). step).

On the other hand, when the portable terminal 10 cannot check the DRM information or the content information that the portable apparatus 10 can access when the portable apparatus 10 is connected in step 202, the controller 120 performs the portable apparatus 10. The server 20, 30 in which the feature table of the portable apparatus 10 exists is searched among the plurality of servers 20, 30 by using the manufacturer name, model name, product type, product identification number, and the like. Accordingly, according to the control operation of the control unit 120, the server is connected through the communication module 140, and is provided with a feature table stored in the server 20. (Step 218. Step 220).

According to the present invention having such a configuration, the DRM information and the content information which can be supported by the portable apparatus can be confirmed, and the portable apparatus 10 can convert the format into a format that can be supported by the portable apparatus 10 so that it can be reproduced.

In addition, when the data file is a moving picture, the data file may be converted into a resolution and a bit rate suitable for the portable device 10.

As described above, it has been described with reference to the illustrated embodiment of the present invention, which is merely exemplary, and those skilled in the art to which the present invention pertains various modifications without departing from the spirit and scope of the present invention.
