摘要

According to one embodiment of the present invention, a method by which a source device transmits and receives data by using a high definition multimedia interface (HDMI) can comprise the steps of: connecting to a sink device through the HDMI; receiving extended display identification data (EDID) information from the sink device; parsing the received EDID information and determining an operating parameter; transmitting, to the sink device, a message for indicating an execution of a video mute function; and receiving, from the sink device, at preset cycles, video mute status information relating to whether the video mute function is being currently executed.
