1. A display device, comprising:
circuitry configured to:
transmit first Enhanced Extended Display Identification Data (E-EDID) to a repeater device via a Display Data Channel (DDC) of a High Definition Multimedia Interface (HDMI) cable, wherein the first E-EDID includes a first Vendor Specific Data Block (VSDB) and a second VSDB, the first VSDB includes four fields that correspond to a physical address of the repeater device, and the second VSDB includes a specific field that includes a value changeable from a first value to a second value by the repeater device based on support of at least one extended function, the specific field being different from each of the four fields;
receive an output from the repeater device via at least one Transition Minimized Differential Signaling (TMDS) channel of the HDMI cable, the output from the repeater device corresponding to an output of a transmission device, wherein a value of the specific field in E-EDID based on the first E-EDID is for notifying the transmission device of compatibility status to output the output of the transmission device based on compatibility information associated with the at least one extended function; and
output the received output via a display screen.
