要約
(EN)

An object of the present invention is to provide an adaptor device for a source device that can reduce a connection time to a switching destination in the case where a connection destination is switched. For this, an adaptor device for a source device (104) includes a storage unit (206) that stores format information that is information indicating the format of the video signal; a dummy signal generating unit (204) that generates a dummy signal that is a dummy video signal having the same format as that specified by the format information obtained from the storage unit (206); a control unit (203) that causes the dummy signal generating unit (204) to generate the dummy signal when the video signal is not obtained from the source device; and a wireless transmitting and receiving unit (202) that selectively wirelessly transmits the video signal and the generated dummy signal.
