PURPOSE:To permit flexible use of a plurality of controlled apparatus in a television or like broadcasting equipment by successively scanning a plurality of remote control places from the side of the apparatus and transmitting the state of use of each apparatus in the first half of the sequence of control between the controlled apparatus and the individual remote control places. CONSTITUTION:A plurality of controlled apparatus 1 are connected to a plurality of remote control places, for instance studios 1 to N, by signal lines 8 and control lines 9. In the first half of the control sequence, a network controller 10 successively scans apparatus remote controllers 6 in the individual studios. To this end, the network controller 10 controls a control signal switcher 40. When the network controller 10 is connected to the appratus remote controller 6 in each studio in one-to-one connection, a transmission demand signal is transmitted to the controller 6, and in response to this signal the controller 6 sends back an apparatus connection demand signal from an operation panel 7. The network controller 6 controls signal swircher 3 and control switcher 4 by comparing the demand signal and the connection state. |
