I think 82 to 93 S4C had both C4's 'dirty' national feed, and a clean feed for sending programmes etc in advance, (some were timeshifted before they were seen on C4)
Certainly during the S4C Schools era (1993+) they were working from a dirty C4 feed; I have an example on tape of an S4C junction with a 'flash' of Channel 4 continuity at the end of the junction. I would imagine this would be the same during the ITV Schools 87-93 era.
I don't think there were actually many programmes 'simulcast' between Channel 4 and S4C back then (maybe the odd sports event or newsy programme) so they could get away with a dirty feed for these, probably the same sustaining feed sent to the ITV regions with everything there except ads. Of course, if they recorded a lot of programmes down the line from the 'live' C4 feed to play back later, I can see why a clean feed would be preferable.
As Marky said, if some programmes were clean fed to S4C prior to being transmitted on 4 (I think Brookside used to debut on S4C at 6pm) then surely this same feed could allow a programme to bypass C4 pres and go clean to S4C whilst actually being transmitted on 4?
On that subject I can remember being on holiday in Wales in the 1970s. Star Trek in those days was 20:10hrs on Monday night, but BBC Wales timeshifted it to Sunday afternoons. I watched it on BBC Wales, and during the end credits the London continuity announcer said' . .and Star Trek will be back again next Monday at ten past eight.. ", At which point the BBC Wales announcer chipped in.." and here on BBC Wales, at half past three next Sunday !'
I'm sure S4C were similarly caught out over the years !
It was keyed over to produce the tapes that S4C played out to cover C4's junctions.
Did S4C work from a dirty feed of C4 or did they get clean feeds?
