[Object] To increase the usability for users without decreasing the security level. [Solving Means] A personal computer (PC) 10 is connected to a television receiver (TV) 30 using an HDMI cable 1. When a video signal is transmitted from the PC 10 to the TV 30, a TMDS channel in the HDMI cable 1 is used. A high-speed data line that performs bi-directional communication using predetermined lines of the HDMI cable 1 (e.g., a reserve line and an HPD line) is provided. In PC 10, a firewall is set. When, for example, being connected to the PC 10, the TV 30 transmits a firewall turn-off command to the PC 10. Alternatively, when, for example, performing data transmission using the high-speed data line provided between the TV 30 and the PC 10, the TV 30 transmits a firewall turn-off command to the PC 10. The security level and connectivity can be maintained without troublesome setting performed by the user and, therefore, the usability for users can be increased.
An electronic apparatus characterized by comprising:
A method for turning off a firewall performed by an electronic apparatus, the electronic apparatus including a signal receiving unit configured to receive a video signal from an external apparatus via a transmission path using a plurality of channels and a differential signal and a communication unit configured to perform bi-directional communication using predetermined lines forming the transmission path, characterized by:
