Abstract: A method for transmitting and receiving data of a sink device by using HDMI is disclosed. A method for transmitting and receiving data of a sink device by using HDMI comprises receiving video data through at least one channel of HDMI from a source device; generating an error counter value by performing CED (Character Error Detection) on the received video data; in case the error counter value exceeds a threshold value, transmitting to the source device a CEC message requesting resolution change of the video data; and receiving video data with a resolution changed according to the CEC message from the source device.
