TW200539137A - Recordable disc drive - Google Patents

Abstract

A recordable disc drive includes a recorder, a control unit, and a TV tuner. The TV tuner is used to receive and select a TV signal. The control unit processes the TV signal from the TV tuner, and outputs it to a outer computer through a USB2.0 cable for decoding and editing. Then, the computer transits the compressed format back to the control unit through the same USB2.0 cable. The recorder receives the compressed format to record on a optical disc so as to simplify the connection and achieve a multiple function.
