摘要：
The present invention discloses a method for transmitting and receiving data of a sink device by using HDMI (High Definition Media Interface). A method for transmitting and receiving data of a source device by using HDMI comprises requesting a sink device to read out EDID (Extended Display Identification Data) when the sink device is connected; receiving from the sink device EDID including decompression capability information of the sink device; transmitting operation parameter information determined on the basis of the EDID, where the operation parameter information includes compression metadata; and transmitting the compressed video data.
