Abstract:
An input switching apparatus includes a plurality of AV signal input units; a communication unit that communicates with another AV device; an input selection unit that selects one of the plurality of AV signal input units; and a selection control unit that switches selection of the input selection unit in accordance with a switching request message for requesting switching of the input selection unit from an origin position to a destination position when the communication unit receives the switching request message. While the input position holding mode is activated, the selection control unit holds the selection of the input selection unit even when the switching request message is received, and transmits a message for causing another device to perform a switching from the destination position to the origin position.
