DIGITAL BROADCAST RECEIVER APPARATUS AND DIGITAL BROADCAST RECEPTION METHOD

摘要

This invention provides detailed operations of a transmitter apparatus and a receiver apparatus that are capable of reproducing, possibly without delays, up-to-the minute earthquake reports conveyed via digital broadcasts. There are included a receiving unit for receiving the conveyed signal; a broadcast modulating unit for demodulating the digital broadcast signal from the conveyed signal received by the receiving unit; an emergency alarm broadcast activation flag detecting unit for detecting the emergency alarm broadcast activation flag from the conveyed signal received by the receiving unit; and an earthquake movement alarm information demodulating unit for demodulating the earthquake movement alarm information signal from the conveyed signal received by the receiving unit.
