PROBLEM TO BE SOLVED: To distribute received signals to plural pieces of connected equipment and to control one reception terminal through plural pieces of control equipment by discriminating control signals to be inputted, deciding priority and outputting the control signals according to this priority. SOLUTION: In order to avoid the collision of control signals from plural simplified control terminals 300, the priority of the simplified control terminals 300 is stored in a non-volatile RAM inside a control microcomputer 160. When there is the request of channel change from the simplified control terminal fitted to a TV receiver 200 while a computer connected to a signal output terminal 190 receives an information signal from a reception terminal 100, corresponding to identification information contained in the control signal so as to show the equipment connected to the reception terminal 100, an interruption control circuit 170 inside the reception terminal 100 ignores this request by discriminating the priority of the request from the simplified control terminal is lower. Thus, the information reception at the computer can be prevented from being interrupted by the request from the simplified control terminal as a result.
