There are a few nits with your reply.
"As a broadcaster at a small market PBS station, I can tell you that the
most
likely deployment of the BF by us will to be to simply turn it on and leave
it on, and we aren't the only ones who will do so. (As Ron Popeil says
about his counter top rotisserie; "set it and forget it!" This probably is
why Samsung is taking such pains now to get their STBs in for upgrade. They
know that they will be hit with a flood of angry customers in the very near
future."
In coming years, this will only be a limitation for stations without
automation systems. PMCP (the protocol designed to permit dynamic changes
in PSIP and other metadata) will be supported by more than one automation
system supplier.
"The broadcast flag is in the PSIP data, so the BF is set on a program by
program basis, without regard to commercials. Theoretically, you will be
able to see which upcomming programs are protected, depending on how many
hours' worth of program guide a station transmits."
You are speaking, I assume, with the feature set of (I assume the current
version) of your PSIP generator. And, I frankly doubt that you will be able
to do this, since there is no requirement in the spec (A/65) and the
candidate spec for PMCP (CS/75) to transmit broadcast flag for non-current
programming. In many cases, whether the flag is invoked may not be known
until moments before the show is aired.
With the PMCP CS, the ultimate authority on whether the flag is transmitted
is the content itself. That means, as a lowest common denominator, that
whether the flag is transmitted is determined a few moments before the
content is aired.
