<P>PROBLEM TO BE SOLVED: To provide a source device providing content to a sink device by using an HDMI or DVI communication interface, and a communication method thereof. <P>SOLUTION: A source device providing content to a sink device and a communication method thereof are provided. The communication method of the source device transmits a communication signal including an HDCP signal to the sink device. When an HDCP communication result is received by the sink device, a communication state with the sink device is determined by using the HDCP communication result, and the communication signal is adjusted according to the determined communication state. Therefore, a communication state between the source device and the sink device is determined by using the HDCP communication result so as to provide optimal content to a user by automatically adjusting communication environment according to the determination result. <P>COPYRIGHT: (C)2013,JPO&INPIT |
