So one of my local TV stations seemingly stopped sending program
information data--you know, the text that says what's on, what's going to
be on, and explaining in more detail what's on. Landing on that channel,
display simply showed "- No program information -". (BTW, this seems to be
the default for all of the minor little public TV stations around here,
not including the big PBS stations which are diligent about supplying this
information.)

OK, no big deal, but slightly annoying, so I fired off an email to the
station, alerting them to this situation and asking them if this was due
to an omission at their end. (I confess I really don't know what that
information is called, or how it gets supplied at their end. All I know is
that it is somehow transmitted as part of the DTV datastream.)

Well, a day or two later, the program information started appearing for
that station. I figured it *might* have been on account of my email--big
slaps on the back for me as an Alert Citizen!--but since they hadn't
replied, I had no way of knowing.

Then a couple days after that I got a reply back. The station's operations
manager wrote and told me that they (the station) was supplying that
information, and therefore if I wasn't seeing it, it was probably due to a
problem at my end. He suggested doing a complete rescan (not an "update
scan") on my DTV box.

I wrote back, and he replied to that. Here's what he said, in part:

Nothing changed on our end. However it is not unheard of for
set-top-boxes to need to reload the PSIP tables for a channel once in a
while. Forcing a rescan forces the tables to reload. Eventually they
will usually reload on their own which is probably what happened in your
case.

(I had done nothing to my DTV box this whole time.)

So does anyone know if this is correct? Now there's another station (one
of the big networks, not a local independent) that's missing its program
info. Is it possible that my DTV box would selectively omit this
information for just one or a few stations? Every other station shows this
info for me, with the exceptions noted above.


IME DVB-T STBs seem particularly prone to mains borne noise and spikes
corrupting the various bits of NVR data, you could try a mains conditioning
socket strip to clean up the supply or run it through a UPS - handy for
power outages that would mess up recordings on a PVR, otherwise doing the
occasional re-scan is not such a big deal.
