A broadcast receiving device capable of easily setting area information. A control unit of a DVR transmits an acquisition request for area information to a TV. When the control unit receives a response to the acquisition request from the TV, the control unit extracts area information from the received response and performs a channel presetting using the extracted area information. A control unit of the TV has area information stored therein. When the control unit receives an acquisition request for area information from the DVR, the control unit transmits, as a response to the request, the stored area information to the DVR.

When a conventional audio video system is used, it is necessary to identify an input source of audio video information. For this reason, complicated operations and slow operation times have been a problem. A control apparatus () includes: an instruction receiving unit () for receiving an instruction to be provided to an audio video supplying apparatus (to) which is an input source of audio video information currently outputted from an output apparatus () that outputs the audio video information; a determination unit () for determining one of the audio video supplying apparatuses (to) to be the input source of the audio video information currently being outputted from the output apparatus (); and a control information sending unit () for outputting control information to the audio video supplying apparatus (to) determined by the determination unit (), the control information corresponding to the instruction received by the instruction receiving unit () and being used for controlling the audio video supplying apparatus (to).

A network system according to an implementation of the present invention involves: determining whether or not a matching address is found by comparing (i) an apparatus address, of an apparatus connected to an HDMI network, which is obtained via the HDMI network with (ii) an apparatus address, of an apparatus connected to another network, which is obtained via the other network (S). Here, the matching address represents a match between the apparatuses addresses. When determining that the matching address is found, the implementation of the present invention involves determining that the terminal apparatus having the matching address is connected to a control apparatus via both of the HDMI network and the other network (S).

To easily ensure that appropriate recognition information is used. A remote control system () includes a DVR () and a remote control () that controls the DVR () via a wireless communication path. The remote control () which is one apparatus out of the DVR () and the remote control () obtains, by a wireless reception unit (), recognition information used by the apparatus to uniquely recognize the other apparatus, via another communication path (a communication path through a TV ()) different from the wireless communication path connecting the apparatus and the other apparatus. When a connected apparatus recognized via the wireless communication path is identified by the obtained recognition information, the remote control () sets, by a control circuit (), the connected apparatus as the DVR () which is the other apparatus to enable communication with the connected apparatus.
