Abstract

A signal communication apparatus includes a transmission component, a reception component and an identification information storage component. The transmission component is connectable to an information processing device and a signal propagation medium, and transmits an inputted image signal through the connected signal propagation medium. The reception component is connectable with an image display device and the signal propagation medium, receives the image signal transmitted from the transmission component through the connected signal propagation medium, and outputs the image signal to the connected image display device. The identification information storage component is removably attached to the transmission component, and stores identification information for identifying the image display device. The information processing device acquires the identification information from the identification information storage component connected to the connected transmission component, and outputs the image signal to the connected transmission component in accordance with at least a portion of the acquired identification information.
