Digital file reproduction system and method for driving the same

A digital file reproduction system and a method for driving the same. The digital file reproduction system comprises a body including a hard disk drive (215) for storing a large number of compressed MP3 files, a drive receiver (210) for accommodating the hard disk drive (215), a body controller (230) for reading a list and data of the music files stored on the hard disk drive through the drive receiver, a signal processor (240) for expanding the music file data read by the body controller (230) and converting the expanded music file data into an analog voltage signal, and a power supply (205) for supplying power to the system. A remote controller (100) includes a display (120) for displaying the music file list read by the body controller (230), a button pad (110) for selecting a specific music file in the music file list displayed on the display (120) and instructing the body controller (230) to output data of the selected music file, and a sub-controller (130) for receiving the music file list read by the body controller (230), displaying it on the display (120), highlighting the specific music file selected by the button pad (110) and outputting a control signal to the body controller (230) in response to the instruction from the button pad (110). An audio generator receives the analog voltage signal from the signal processor, converts it into an audio signal and outputs the converted audio signal externally. Embodiments with a CD-rom drive in place of a hard disk drive, and movie files in place of music files are also claimed.
