| abstract | PROBLEM TO BE SOLVED: To monitor a signal that directly reflects the image quality of a received image in relaying digital waves. A control circuit 43 monitors a C / N ratio and a BER value based on an output of a demodulation integrated circuit 42, and constantly monitors whether the C / N ratio and the BER value indicate abnormality. To do. For example, when the C / N ratio or BER value continuously shows an abnormal value, an abnormal signal is generated, and when the C / N ratio or BER value does not show an abnormal value, it is determined that normal broadcasting is being performed. . Such a C / N ratio, a BER value, a determination result, and the like are output from the control circuit 43 to the transmission medium 49 as an evaluation result relating to the operation status, and transmitted to the management control center 50 via the packet communication line PN. Based on the evaluation results detected by the station monitoring devices 40 (1) to 40 (m), the management control center 50 grasps the individual operation status of each relay station 20, 30 (1) to 30 (n) in real time. can do.
