PROBLEM TO BE SOLVED: To perform signal processing appropriately regardless of the failure situation of a wired line, in a signal processor which can receive a signal via a wired line and a wireless line.SOLUTION: A reception signal processing system includes a broadcast controller for controlling start and end of broadcast on the basis of a signal inputted, a signal processor for monitoring the failure of a wired line connected externally, and outputting a control signal for a broadcast controller on the basis of a predetermined signal received via the wired line, and a wireless receiver for forming a first circuit, i.e., a signal path between the signal processor by closing a contact terminal in response to a predetermined wireless signal received via a wireless line. The signal processor is not connected with the first circuit until the failure of the wired line is detected, and connected with the first circuit when the failure of the wired line is detected. |
