In particular, upon receiving the unlock signal through the docking connector module 255, the controller 270 sets the media player 200 to the unlock mode. In the unlock mode, the controller 270 controls the digital broadcasting content received from the docking station 100 to be stored in the storage unit 260 or to be played back on the display device 400 through the docking station 100. Can be controlled. In addition, in the unlock mode, the controller 270 may control digital content stored in the storage unit 260 to be played on the display apparatus 400 through the docking station 100. The controller 270 may set the media player 200 to be in the lock mode at a predetermined period or at a certain time. The controller 270 may set the media player 200 to be in a lock mode when a forced lock mode instruction is given through the user input unit 230 or the mobile communication module 217.

4 is a flowchart illustrating an authentication method of a docking station according to an embodiment of the present invention. See FIGS. 1-3.

Referring to FIG. 4, the docking station 100 waits in a standby mode state (S500). In the standby mode, the docking station 100 may be in an idle state to save power.

The docking station 100 determines whether the media player 200 and the authentication device 300 are inserted to receive identification information and an authentication code from each component (S510). If any one is not received, the docking station 100 will remain in the standby mode (S500).

When receiving the identification information and the authentication code, the docking station 100 checks whether the connected media player 200 and the authentication device 300 are a pair of registered devices (S520). This verification process compares the received identification information and authentication code pairs with previously stored identification information and authentication code pairs to determine whether they are the same. When the received identification information and the authentication code pair are not registered pairs, the docking station 100 may display the display module 141 of the docking station 100, the display module 241 of the media player 200, or the display device 400. Through which one, it is determined whether to register the pair of the connected media player 200 and the authentication device 300, and it is determined whether there is a registration instruction input (S540). If there is a registration indication input, the docking station 100 stores identification information and authentication code pairs of both connected components. If there is no registration instruction input, the docking station 100 remains in the standby mode (S500).

When the received identification information and the authentication code pair are registered, the docking station 100 switches to the operation mode (S530) and transmits a lock release signal to the media player 200 (S535).

When the connected media player 200 and the authentication device 300 pair successfully register or successfully authenticate, the docking station 100 causes the display device 400 to play digital broadcast content or digital content.

Meanwhile, the present invention can be implemented as a processor-readable code in a processor-readable recording medium provided in a portable terminal. The processor-readable recording medium includes all kinds of recording apparatuses in which data that can be read by the processor is stored. Examples of the recording medium readable by the processor include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may be implemented in the form of a carrier wave such as transmission over the Internet. In addition, the processor readable recording medium may be distributed over networked computer systems so that code readable by the processor in a distributed manner can be stored and executed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
