Abstract
A content providing device includes a first wired interface that communicates with a first external electronic device through a wired cable or a wireless dongle, and a processor that determines whether the wired cable or the wireless dongle is connected to the first wired interface, and selects a power source based on whether the wired cable or the wireless dongle is connected to the first wired interface.
Claims12
A content providing device comprising:
- a power interface configured to receive power from an external power source through a power cable;
- a first wired interface configured to communicate with a first external electronic device selectively through a wired cable or a wireless dongle;
- and
- a processor configured to:
- in response to determining that the wired cable is connected to the first wired interface and the wireless dongle is not connected to the first wired interface, receive the power from the first external electronic device through the wired cable;
- and
- in response to determining that the wireless dongle is connected to the first wired interface and the wired cable is not connected to the first wired interface, receive the power from the external power source through the power cable, wherein
- the first wired interface comprises a connector,
- the connector comprises a pull-down resistor, and
- the processor is further configured to:
- in response to determining that the wired cable or the wireless dongle is connected to the connector, determine a voltage level applied to the pull-down resistor, and
- determine, based on the voltage level applied to the pull-down resistor, whether the wired cable or the wireless dongle is connected to the first wired interface.
A power source controlling method of a content providing device, the method comprising:
- in response to determining that a wired cable is connected to a wired interface and a wireless dongle is not connected to the wired interface, receiving power from an external electronic device through the wired cable;
- and
- in response to determining that the wireless dongle is connected to the wired interface and the wired cable is not connected to the wired interface, receive the power from an external power source through a power cable, wherein
- the wired interface comprises a connector,
- the connector comprises a pull-down resistor, and
- the method further comprises:
- in response to determining that the wired cable or the wireless dongle is connected to the connector, determining a voltage level applied to the pull-down resistor, and
- determining, based on the voltage level applied to the pull-down resistor, whether the wired cable or the wireless dongle is connected to the wired interface.
A non-transitory computer-readable recording medium having embodied thereon a program, which when executed by a processor causes the processor to execute a method, the method comprising:
- in response to determining that a wired cable is connected to a wired interface and a wireless dongle is not connected to the wired interface, receiving power from a first external electronic device through the wired cable;
- and
- in response to determining that the wireless dongle is connected to the wired interface and the wired cable is not connected to the wired interface, receive the power from an external power source through a power cable, wherein
- the wired interface comprises a connector,
- the connector comprises a pull-down resistor, and
- the method further comprises:
- in response to determining that the wired cable or the wireless dongle is connected to the connector, determining a voltage level applied to the pull-down resistor, and
- determining, based on the voltage level applied to the pull-down resistor, whether the wired cable or the wireless dongle is connected to the wired interface.
