DVB Emergency Warning System

The capability to inform a wide audience of immediate dangers such as earthquakes is a relevant feature for every broadcast system. The Emergency Warning System defined by DVB provides the necessary mechanisms to distribute relevant information to the general public in case of emergencies.

All core DVB transmission standards (DVB-S, S2, T, T2, C, C2, IPTV) allow the integration of an Emergency Warning System through the inherent DVB-SI standard. A new DVB Emergency Warning System fact sheet describes which DVB standards and documents are required and how the system works.
