Another BBC2 local opt on analogue

I've never seen the programme, is it 16F16 when seen on BBC 1 via digital
platforms ?

I presume so, and 12F12 cutout on analogue?

Leeds is a 16:9 site, but how did you deduce the programme was produced in
4:3, and then cropped to 14:9 letterbox ?

Aside from the lack of ARCing artefacts associated with 14:9, the "masking
box" itself leaves a couple of clues -
- it blacks out a few lines more than a 14:9 ARC would
- it leaves a small strip of unmasked active picture at the top of the frame

Ah, you should presume nothing when it comes to Auntie Beeb, and her
engineering practice. I'll set my PVR to record next week's show and
take a look.

Well that photo raises two questions straight away.

1: I wonder what the ITV style cue dot is for ?

2: What sort of Rugby highlights programme is it, that features boating !

afaik it's to switch fill-in relay stations which, although based in the north
west region, get a superior off-air signal from out-of-region main
transmitters.
These stations need to carry northwest local programming, so basically they
have two sets of receive aerials, and are switched over by the cue dot when an
opt is taking place.

That was the generic natural history programme which followed the rugby
The rugby programme was played out in the same way though - 12F12 with masking
bars.

Ah, yes, I remember now. It was for Douglas on the IOM. It used to take
its main analogue RBL from Caldbeck, but during opts would be switched
to Winter Hill. Totally superfluous now of course. Caldbeck analogue has
gone, Douglas and its relays have been DSO'd, and Douglas DTT is fibre
fed from the 'Winter Hill' SIPSI.

Isn't Leeds widescreen-equipped yet? I'm a bit confused by the use of
4:3 and a 14:9 masking box if so.

He 'deduced' that because he's a clueless little ****, that's why.

Are these not all in the Isle of Man and receive BBC-1 North East from Sandale
for network programming and from Winter Hill for regional programming?

Maybe it's still used by some other relay stations?

Keep up at the back. Sandale has never transmitted UHF analogue versions
of BBC 1 or 2 England, only Scotland, and in any case for TV it's now
dead (as is Caldbeck analogue, the station that did feed the IOM)

I don't think so, with Caldbeck gone that rules out anything to the
north, I'm not aware of any near the Yorks border, in fact a couple were
migrated to Emley for BBC1/2 a few months ago. I suspect the cue-dot
indent has just been left in circuit because it's been forgotten about.

I know -- I sometimes get Caldbeck and Sandale mixed up, because they
are close to each other.

Yes teacher, I will write out one hundred times

Sandale -- BBC-1 Scotland analog but no more**, only VHF radio now

** This transmitter stopped transmitting television services
on Wednesday 22nd July 2009







, and in any case for TV it's now
dead (as is Caldbeck analogue, the station that did feed the IOM)
