Maybe its a tribute to the power of the "EAS" brand that even broadcasters
think EAS is the only way for people to learn emergency information. Do
we need yet another brand for the overall emergency information system?
As pointed out, broadcast channels don't work well as a way to reach
people who aren't listening or viewing broadcast channels at 3am. EAS
receivers don't work well because the public (and consumer electronic
liability lawyers) can't predict which broadcast channel will carry local
alerts. Instead of trying to make broadcast channels into something they
aren't suited for, figure out the roles for all the different communication
channels and how they can complement each other.
CAP is supposed to be technology and communication channel independent.
For example, the future generation Google TV may have CAP warnings
built-in, and not depend on a local broadcast channel. Telephones ring
still ring at 3am. Cell phones get messages and buzz. Community warning
sirens sound. Yes, individually each communication channel has its own
weaknesses. But that is why diversity is important.
Not every device needs to transmit or understand CAP. Community warning
sirens won't modulate a digital signal containing a CAP message.
Do broadcast channels still need inter-station signalling (SAME or
something else) to distribute emergency information between them as a
backup when normal programming sources and channels are disrupted?
Digital signals can carry additional information associated with
the main programming channels, so the cueing details don't have to
interrupt the main program.
