If it is detected that the external device is connected, the control unit 142 may notify the microcomputer 120 that the external device 10 is connected.

Upon receiving the wake-up signal from the connected external device 10, the control unit 142 can transmit the received wake-up signal to the microcomputer 130. [ The control unit 142 generates a wake-up start command by combining the received wake-up signal and port information corresponding to the external device 10 that has transmitted the wake-up signal, and transmits a wake-up start command to the microcomputer 130 .

The control unit 142 can determine whether the connected external device 10 is a rechargeable device.

18 is a diagram for explaining a wake-up method according to an embodiment of the present invention.

First, in a state in which the media player device is in the standby mode, it is checked whether an external device is connected to a plurality of contact locations (S1810).

When the external device is connected to the media player device, the media player device is woken up (S1820). And may be implemented in the form of waking up the media player device when a wake up signal is received from a connected external device.

FIG. 19 is a view for specifically explaining the wake up operation of FIG. 18;
