If the external device 100 is detected as being connected to the media player device 100, the microcomputer 120 may control the power supply unit 110 and the interface unit 140 to wake up the media player device 100. Can be.

On the other hand, the microcomputer 120 may perform a wakeup operation when a wakeup signal is received from an external device 100 that is already connected. For example, when the media player device 100 enters the standby mode while the external device 100 is connected, the microcomputer 120 wakes up when the media player device 100 receives a wake-up signal from the external device. The power supply unit 110 and the interface unit 140 may be controlled to be up. In this case, the wakeup signal may be received through the first pair minus contact location described above.

The operation in which the media player device 100 wakes up the external device 100 'differs only in that the wake-up signal is transmitted using only one contact location, and the detailed operation is the same as that described with reference to FIG. Duplicate explanations are omitted.

7 and 8, the microcomputer 120 directly detects a signal received from two contact locations among a plurality of contact locations, recognizes a connection of an external device, and receives a wake-up signal.

In detail, the interface unit 140 may determine that the external device 100 'is connected using a first pair minus contact location among a plurality of contact locations connected to the external device 100'.

When the external device 100 ′ is connected, the interface unit 140 may notify the microcomputer 120 that the external device 100 is connected. In this case, when the media player device 100 is in the standby mode, the interface unit 140 may notify the microcomputer 120 of the wakeup signal. In this case, the microcomputer 120 receiving the wakeup signal may control the power supply unit 110 to allow the media player device 100 to wake up.

When the interface unit 140 receives the wake up signal from the external device 100 ′, the interface unit 140 may notify the microcomputer 120 of the received wake up signal. For example, when the media player device 100 enters the standby mode while the external device 100 is connected, when the wake-up signal is received from the external device 100 ', the interface unit 140 receives the media player device.
