Abstract: When an HDMI key of an input operation unit is operated, a control unit outputs, to a projector, a control signal indicating that an HDMI terminal is selected from a control signal output unit, such that video based on a video signal separated from an input signal to the HDMI terminal is projected, and a sound signal separated from the input signal to the HDMI terminal is output from a mini jack to a mini jack of a switcher. The control unit issues an instruction to a sound signal selection unit to select a sound signal which is input to the mini jack serving as a sound input terminal corresponding to the HDMI terminal. As a result, sound based on the sound signal included in the input signal to the HDMI terminal is output from a speaker.
