PDC killing Freeview?

Can the Program Delivery Control signal kill my Freeview Box?

I am temporarily occupying a bungalow, surrounded by houses, some 30
kilometers west of the Heathfield transmitter and I guess it is likely the
DTV signal is not too good.

The existing aerial is an elderly 625 type feeding a (free!) Sagem Freeview
box. This box regularly crashes and resets back to the channel I was
already viewing, and when I check the time it seems to me that it is always
at the moment when another program (not necessarily on the same channel) is
about to start.

Although I am not looking for a solution as I shall be moving back home
shortly I wonder if it is the PDC signal causing this problem - or does
somebody have a better idea? I must admit I have not analysed the pattern
of crashes to confirm the possible link with changes on other channels which
use PDC.

Any ideas anyone?

Well do not know answer for you, but my Sagem as just been replaced. It was
driving me crazy for always saying "New Channels detected " several times a
day.
I just thought it had past its use by date.

FREESAT HD as it is now it is a joke.

No. The PDC signal is carried within the data stream of teletext only on
the analogue transmissions. There's no way it can influence the data on
the DTT muxes. However, are you thinking of the 'Accurate Record' flags
as carried on DTT ? If so, I suppose what you suggest is possible, but
still highly unlikely.

I have a Sagem box which has the same problem. I guess you watch a lot of
BBC, for it only occurs on the BBC channels (including interactive and radio
on both muxes). Clearly a software glitch and you are thinking along the
right lines that a data stream (but not PDC) is causing the box to crash.
The solution would be a software upgrade.

The psu is crap?

I have a netgem I player the one for blind folk with the audio tags etc, and
it has two interesting quirks.
Firstly on Sky 3 it can just reset the box ffor no apparent reason, and on
some ItV channels where AD is allowed as on, but no AD is present,
occasional glitches in the normal sound occur as if the volume is being
ducked for an AD comment, but ther is none. This is cured by turning off the
AD, so I suspect they are doing something clever which is confusing the AD
system on the box.

Thanks for your interest in this small mystery folks. In fact last evening
and this afternoon the picture has been breaking up on the weaker channels
(including ITV Meridian) and I did notice we had the 6pm collapse twice at
exactly 18:00:00 and again at 18:03:00 while tuned to Sky 3 (so not the same
as Sheila).
I think either Brian Gaff is correct with "psu is crap", or Sagem is crap,
or bearing in mind the box was a freebie "you gets what you pays for".
Anyway back to Sky satellite box shortly and it will be "you PAYS for both
what you gets and often what you don't want to get"

ps - 2 questions....refer me to an FAQ if necessary!
What is AD?
Is "Accurate Record" a "PDC" for the freeview PVR's benefit?

Audio Description. It's a selectable audio commentary track for visually
impaired viewers.

Yes !
