Abstract:
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.
