Abstract:
1. An input switching apparatus of an audio/video signal, the apparatus comprising: a plurality of audio/video signal input units to which audio/video signals are input; a communication unit that communicates with another audio/video device; an input selection unit that selects one of the plurality of audio/video signal input units to thus receive the audio/video signal of the selected audio/video signal input unit; 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, wherein the selection control unit is configured to transmit a message for directing another device to perform a switching from the destination position to the origin position through the communication unit even when the communication unit receives the switching request message from said another audio/video device for requesting switching of the input selection unit from the origin position to the destination position, the selection control unit is configured to activate and inactivate an input position holding mode, while the input position holding mode is inactivated, the selection control unit performs switching of the input selection unit when the communication unit receives the switching request message for requesting switching of the input selection unit from the origin position to the destination position, and while the input position holding mode is activated, the selection control unit transmits the message for directing another device to perform the switching from the destination position to the origin position through the communication unit even when the communication unit receives the switching request message from said another audio/video device for requesting switching of the input selection unit from the origin position to the destination position.
