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 () includes a storage unit () that stores format information that is information indicating the format of the video signal; a dummy signal generating unit () 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 (); a control unit () that causes the dummy signal generating unit () to generate the dummy signal when the video signal is not obtained from the source device; and a wireless transmitting and receiving unit () that selectively wirelessly transmits the video signal and the generated dummy signal.

Adaptor device for source device and control method of adaptor device for source device

In a wireless communication adapter device, in order to reduce connection time to a destination when another sink device is selected as the destination, a control unit included in the wireless communications adaptor device determines whether a device ID of an adapter device for a sink device and EDID information corresponding to the device ID are registered in an EDID managing table. The device ID and the EDID information are obtained through authentication processing with the adapter device for the sink device. When the device ID is registered, the control unit copies the EDID information corresponding to the device ID to the EDID table. When the device ID is not registered, the control unit obtains the EDID information from the authenticated adapter device for the sink device, associates the EDID information with the device ID, and stores the EDID information and the device ID in the EDID managing table.
