Abstract
A sink device comprising a connector which has a first ground (GND) corresponding to a first standard; and a processor which receives a signal from a source device, via the connector, and if the received signal is of a second standard corresponding to a second GND that includes the first GND, requests, from the source device, information about the signal of the second standard.
Claims13
A sink device comprising:
- a connector connectable to an external source device, the connector corresponding to a first standard of high-definition multimedia interface (HDMI), the first standard being HDMI 2.1;
- and
- a processor configured to:
- receive a signal to be transmitted from the external source device through the connector while the connector is connected to the external source device;
- identify whether the received signal is of a second standard of HDMI, the second standard being HDMI 2.0;
- in response to the identifying that the received signal is of the second standard of HDMI, request for a correction of the signal transmitting from the external source device which is identified as the second standard of HDMI to the external source device to resolve electromagnetic interference (EMI) problem;
- to receive the signal that has been corrected from the external source device;
- and
- to provide a content corresponding to the received signal that has been corrected.

A source device comprising:
- a communication interface connectable to a connector of an external sink device, the connector corresponding to a first standard of HDMI, the first standard being HDMI 2.1;
- and
- a processor configured to:
- control the communication interface, while the source device is connected to the connector of the external sink device through the communication interface, to transmit a signal of a second standard of HDMI, the second standard being HDMI 2.0;
- in response to receiving a correction request for the signal of the second standard of HDMI to resolve EMI problem through the communication interface, correct the signal of the second standard of HDMI based on the correction request;
- and
- control the communication interface to transmit the signal that has been corrected to the connector of the external sink device.

A control method for a sink device having a connector connectable to an external source device, and a processor, the method comprising:
- receiving a signal to be transmitted from the external source device through the connector corresponding to a first standard of HDMI, the first standard being HDMI 2.1, while the connector is connected to the external source device;
- identifying, by the processor, whether the received signal is of a second standard of HDMI, the second standard being HDMI 2.0;
- in response to the identifying that the received signal is of the second standard of HDMI, requesting for a correction of the signal transmitting from the external source device which is identified as the second standard of HDMI to the external source device;
- receiving the signal that has been corrected from the external source device;
- and
- providing a content corresponding to the received signal that has been corrected.
