Emergency Warning System: Alert The Public of Any Emergencies Via DTT

1. The document describes an Emergency Warning System (EWS) that uses digital terrestrial television (DTT) to alert the public of emergencies. 2. It involves collecting data from sensors and agencies, generating emergency information and transmitting it over multiplexers and transmitters embedded in DTT signals for display on receivers and set top boxes. 3. The EWS flow involves collecting hazard data, processing it, converting it to a transport stream, multiplexing it with other broadcasts and transmitting it through various stations, regions and networks to reach remote areas.
