An external device may recognize, in the case of including a communication unit that executes communication via a communication path made up of a pair of differential transmission paths included in a transmission path, information relating to the communication unit thereof. A disk recorder transmits function information indicating that a communication unit (high-speed data line I/F) configured to execute communication with an external device via a communication path made up of a reserve line and an HPD line of an HDMI cable to a television receiver via a CEC line that is a control data line of the HDMI cable. The television receiver receives function information, whereby whether or not the disk recorder is an eHDMI-compatible device can be determined, and in the case of an eHDMI-compatible device, a compatible transmission format (application) can be recognized.
