Emergency Warning & AlertTools for Information Dissemination

What is your country‘s approachtoday on information disseminationin case of disasters?

Analog AM/FM Radio Mobile phones, SMS Internet / Social Media TV (satellite, terrestrial) Special Devices, Alarm Systems

Now also: Digital Radio!

Emergency Warning & AlertUnique Benefits for Information Dissemination

Radio is ubiquitously available:

at home

at work

in the car

as portables & in mobile phones

outdoors & indoors

Radio is a companionwith an everyday purpose unintrusive and always present

Emergency Warning & AlertUnique Benefits for Information Dissemination

Radio is independentfrom local infrastructure:

Battery powered / wind-up

No satellite dishes / settop boxes

Transmitter coverage from outside disaster area:E.g. high power, high tower

Secured transmitter sites(backup power etc.)

Well-controlled infrastructure

Emergency Warning & Alert in Digital RadioEWF vs. EWS

EWS – Emergency Warning System„The EWS feature is intended to provide for the coding of warning messages […] and will only be evaluated by special receivers.“ E.g. Siren activation

EWF – Emergency Warning FunctionalityEmergency Broadcast to the public giving all relevant information on Digital Radios (DAB and DRM).

Emergency Warning & Alert in Digital RadioListener Experience

!! When the alarm signal is triggered by authorities:

• All running digital receivers pick up alarm signalfrom currently received service, and switch to emergency broadcast (if required)

• Turned-off receivers may switch on automatically(requirement to be communicated to rx mfcts)

Receivers present the audio content of the emergency programme

Receivers with appropriate screen in addition present• detailed information and

instructions (Journaline),• text-headlines (Dynamic Labels) and• Images (Slideshow, if available)
