| Outline of Final Research Achievements |
In emergency such as earthquake and tsunami, an ISDB-T digital television broadcaster would send a special signal to automatically wake up their receivers. However, the mechanism at the receiver occasionally causes wrong alerts (false alarms) due to the reception bit errors. Therefore, a method of reducing false alarms has been proposed through this research. In addition to the wake-up signal, the proposed method uses the parity, not for the original purpose of error correction, but only for reliably determining the wake-up signal. Comparing it with the conventional methods, the proposed method reduced the false alarms less than one-thousandth.
