Abstract:
ISDB-T (Integrated Services Digital Broadcasting-Terrestrial) digital television receivers would wake up themselves when the broadcaster sends a special control signal. TMCC (Transmission and Modulation Configuration Control), one of the ISDB-T control signal, conveys the emergency wake-up trigger as well as the modulations and coding rates information. Even the TMCC also contains parity for the error correction, the receivers would cause misdetection or make false alarms the trigger in mobile and erroneous transmission channels. If we assume information of the modulations and the coding rates hold between before and after the emergency alert is advised, several bits of the parity is also used for the trigger detection because it reflect TMCC information. The majority detection with the parity bits reduces the false alarm. Because the parity can correct TMCC information bit by bit with a majority decoding, this paper compares performance of the two majority detection methods.
