Referring to FIG. 1, a TV system includes a memory card slot 10, and a memory card 20 is mounted in the memory card slot 10. In such a TV system, a memory such as a hard disk may be separately installed.

In the memory card 20, document files that a user intends to output using a TV are recorded. When the initial memory card is loaded, the list of document files is decoded by the decoder 30 and then displayed on the display unit 60 via the display driving unit 50 through the control unit 40, thereby allowing the user to display the list of document files. It becomes possible to confirm.

That is, when the memory card 20 is mounted, when the user selects the search key of the memory card 20 through the remote control unit 90, the list of document files recorded on the memory card 20 is decoded (decoded by the decoder). Decoded through 30 and then transmitted to the control unit 40 to be displayed on the display unit 60.

In this case, when the user selects a specific document file from the displayed document file list, the corresponding document file is decoded and outputted to the controller 40.

As shown in FIG. 2, the decoder 30 includes a parser 31, a format converter 32, and a decoder 33. The parser 31 includes a predetermined data format. When a specific file selected by a user among the document files 21 formatted as (TXT, HTML, HWP, DOC, ..., etc.) is input, the input document file data is parsed and the data contents are analyzed.

The format conversion unit 32 converts the parsed data to match the display format of the display unit 60. In this case, if only the text content exists in the document file, the decoded text data file is output. If the document file includes a different format, the decoder 33 decodes and outputs the audio file and / or the image file. do.
