As the thread title suggests, each day at around 7pm, my signal pixellates and drops out, just for a moment, up to a couple of times. Only on BBC1 (HD or Northwest). Not enough to really annoy (it's only the One Show after all), I'm just interested whether anybody else gets this - and more importantly, why almost the exact same time every night! I hardly ever get this any other time. Foxsat HDR by the way, latest (official) firmware.

Could thIs not be the time the regions rejoin the UK - a known glitch?

Ah. Could well be. A glitch obviously known to many....apart from me that is!

The same thing happens on my box. (BBC1 SE)
During the titles to the One Show, the picture briefly breaks up a bit, then sometimes one or twice more within the first couple of minutes of the show.
It doesn't happen any other time of day and can happen a good few minutes after the switch from the regions and doesn't seem to happen after other regional broadcasts.

I would like to know why this happens as I have been wondering about this as well

This is known by the BBC [in the last weeks} and they said they will address it.

Well I'm glad it's not just me! Come to think of it, it often does break up couple of minutes in, so that should be after the region switch. Bugs me I don't know why it does this!

It's been going on for quite some time now, but I'm glad they know about it. Not really an issue, just something that probably shouldn't happen and it bothers me when I don't know why. Have the beeb said what's causing it, or don't they know? Seems to encompass quite a bit of the country, unless it's localised just to BBC SE and BBC NW!

It depends on which region of BBC1 you are using but is almost certainly down to the switchover of CBBC and Cbeebies to BBC3 and BBC4 on the same transponders. I believe the BBC are aware of the problem and have reported on a forum that they are investigating and trying to solve the problem.

That would make sense - if there's any overlap between the childrens' channels and the evening channels, everything would be momentarily starved of bitrate and so break up.

Thanks for the replies everyone. And my apologies for my inability to use the search function to find the earlier thread! At least it kind of makes sense now.

It happens on channels using the same transponders as the part time BBC3/CBBC and BBC4/Cbeebies as the channels switch at 7pm.

10773 H and 10802 H.

102 BBC Two 10773 H
105 Channel 5 10773 H
106 BBC Three 10773 H
600 CBBC 10773 H
950 BBC 1 London 10773 H
951 BBC 1 CI 10773 H
954 BBC 1 East (W) 10773 H
965 BBC 1 West 10773 H
968 BBC 2 England 10773 H
102 BBC 2 10802 H
107 BBC Four 10802 H
601 CBeebies 10802 H
705 BBC Radio 5 Live 10802 H
706 BBC Radio 5 Live Sports Extra 10802 H
959 BBC 1 S East 10802 H
955 BBC 1 N West 10802 H
960 BBC 1 Scotland 10802 H
970 BBC 2 SCOTLAND 10802 H

Tuning to a different BBC region not using either of the above transponders will avoid the glitches.

There's no overlap: they use the same programme streams. CBBC = BBC Three; CBeebies = BBC Four. All that changes is the channel-to-programme-stream mapping table.

If you watch any of these channels in non-Freesat mode, you can see this happen.
