Abstract: The present specification proposes a method for a source device receiving capability information of a sink device. More specifically, the method comprises the steps of: transmitting, to a sink device, a message requesting for the reading of capability information of the sink device; receiving, from the sink device, first capability information of the sink device; on the basis of a capability information version of the sink device which is readable by a source device, carrying out a version change procedure for changing the capability information version of the sink device; and, on the basis of the version change procedure, receiving second capability information of the sink device, wherein the version of the second capability information is a higher than the version of the first capability information.

Abstract: The present disclosure provides a method for transmitting video data by a source device, by using a high definition media interface (HDMI). In particular, the method comprises the steps of: receiving, from a sink device, capability information about whether reference display model (RDM)-based image processing of the sink device is supported; performing the RDM-based image processing on a plurality of pieces of video data, on the basis of the received capability information; and transmitting, to the sink device, (i) the plurality of pieces of video data on which the RDM-based image processing is performed and (ii) image processing information about a result of the RDM-based image processing, wherein the RDM-based image processing is (i) performed on the basis of a value of a feature of one piece of video data among the plurality of pieces of video data or (ii) performed on the basis of one feature value among feature values related to a separately set feature aside from values of features of the plurality of pieces of video data.
