Enensys: TV-based disaster warnings simplified

Using a TV network to provide emergency alerts is a useful tool for those countries around the world that regularly face potentially dangerous weather events and natural disasters.

To aid this, IBC exhibitor Enensys has developed rEWS (Regional Emergency Warning System) for digital terrestrial TV, both DVB-T and DVB-T2 networks, including those with multiple regions where only one region needs the warning.
rEWS negates the need for special receiver software by using broadcast TV channels to convey the warning message across all TV channels in a region or nationally at the same time.

The message is triggered by signals in the broadcast transport streams, replacing the video and audio service of all channels with the EWS message. Alerts can be also broadcast from selected transmitters only for regional coverage.
