Optical disc drive and method of driving the same

A method of driving an optical disc drive comprising an optical drive module for writing and/or reproducing information to and/or from an optical disc and for processing data from the optical disc, a back-end module that decodes and outputs audio signals and video signals from signals generated by the optical drive module or encodes input audio signals and video signals, and an interface that connects the optical drive module and the back-end module, that connects the optical drive module to an external device, and that selectively controls connection to the first port or the second port, the method comprising:

• obtaining digital data from the optical disc or writing information to the optical disc using the optical drive module;
• obtaining audio signals and video signals by processing the digital data or obtaining digital data by processing input audio signals and video signals using a back-end module;
• and
• selectively outputting digital data from the optical disc drive module to the back-end module and to the external device using the interface.

A multi-functional optical disc drive, comprising:

• an optical disc drive module configured to obtain digital data from a disc;
• a back-end configured to decode and output audio signals and video signals from signals generated by the optical disc drive module;
• and
• an interface configured to selectively connect the optical disc drive module with the back-end and to connect the optical disc drive module with an external device, such that the optical disc drive module is not connected to both the back-end and the external device at the same time.
