Abstract
A reradiation apparatus for terrestrial digital broadcasting includes plural antennas provided on a train and mutually spaced along the running direction of the train, plural receiving processing parts provided corresponding to the antennas, a master selecting part which sets the receiving processing part corresponding to the antenna provided at the rear of the train as a master receiving processing part, a monitoring part which monitors a received state of the terrestrial digital broadcasting signal received by the master receiving processing part and outputs a supervisory signal, a switching part, and a reradiation unit. The switching part chooses the terrestrial digital broadcasting signal received by the master receiving processing part or the terrestrial digital broadcasting signal received by another receiving processing part based on the supervisory signal output by the monitoring part. The reradiation unit reradiates the chosen terrestrial digital broadcasting signal in the train.
