Repeater device and control method

Abstract

A repeater device connected to source and sink devices includes: an input terminal receiving transmission data supplied from the source device; relay means for relaying the transmission data; an output terminal outputting the transmission data relayed by the relay means to the sink device; control means for setting an operating mode of a limited state where a dynamic function of causing a superficial dynamic change and allowing a user to visually confirm the superficial dynamic change is deactivated and only a static function of not causing the superficial dynamic change is activated in response to a user's predetermined operation even when the source and sink device are connected to each other in a controllable state; and switch means for switching activated and deactivated states of a connecting line to the sink device by controlling the ON and OFF states.
