[EAS] Source of the "scary" text in Suffolk Co

[Ed Czarnecki]

>>>Yes.  And the ordering of CAP vs. EAS distribution channel is
unpredictable.  Each of the three messages may have reached different video
participants via a different distribution channel (EAS or CAP) first.

Exactly.  This is the race condition between CAP EAS device polling
intervals and the EAS broadcast relay.  Again, we proposed a solution to
mitigate this race condition, where the EAS unit immediately polls IPAWS
whenever they receive a broadcast EAS message.  The DASDEC already has a few
features in v3.0 that can help give preference to the more informative CAP
message.  But I would like to see an industry-wide coordination on this.

>>>> Depending on which distribution channel video participants received the
message first, decides whether they broadcast a text crawl with only the FCC
required text or both the FCC required text plus CAP text.

Again, right on the mark.  The message was not "truncated" in the sense
something went wrong.  If the broadcast EAS message was received first, then
the short EAS header sentence is transmitted.  The expanded CAP text is of
course not available in broadcast EAS.  The text was not "truncated."  It
was simply not there in EAS.  If the CAP message was received first then the
full expanded text is available.  There are no surprises here - the FCC and
FEMA had been discussing this back with the national EAS test in 2011, where
the concern was that the EAN text from standard EAS would not have any
indication that "this is a test."

>>>> The system worked as designed.  But probably did not work as the EM
expected.

Or understood.  That the output is different from CAP vs. EAS monitoring
sources is something I am constantly reminding EM folks about.  The hybrid
CAP/EAS system has many nuances that are not self-evident to many users.

Yes.  And the ordering of CAP vs. EAS distribution channel is unpredictable.
