Before that, there's no ITV company endcap, which must have been pretty unique, even movies and imports had endcaps. Though sone early-mid 1989 episodes recorded from Central do have their animated endcap at the end, nothing from any other regions though.

I wonder if the fact it was originally produced for Channel Four has anything to do with there being no endcap?

That only makes sense when the show was still on Channel 4 - and it moved to ITV in 1989.

Another Saturday morning ITV technical hitch, this time from Granada. I think the sound is slightly out of sync in the video though.

It appears that sometimes a programme went from the originating station to the rest of the network via THS/LWT. Did it make a difference whether or not the show was live?

I'm sure somebody will correct this, but my understanding is:

Every station had "local ends" to BT, once in BT's network it could be routed as required.

Sometimes it was convenient (and cheaper as BT charged for each switch) to have one company act as a switching point to save on switches or make things operationally more convenient when successive items came from different parts of the network. Often THS/LWT but weekday mornings would have everything going through Granada for example (the 9.25 junction would be tricky otherwise), and of course ATV/Central handled Schools and CITV.

See https://routinesheetsdatabase.co.uk/  you'll see notes about how individual programmes were networked.

In the case of this example I can't think why Maidstone wouldn't have been direct to network (or via Southampton) rather than via LWT.

I've had a chance to look at a copy of the IBA rented circuits dated Jan 1983, so quite a bit later than the date of this fault but probably still very close.

Soton had one incoming circuit from BT Tower and on a Saturday morning that would have been tied up with the commercial exchange from LWT. 

Maidstone has two incoming circuits and one outgoing. It was an operational requirement of the ITV network that ITN could only be one switch away from being fed to the network, Maidstone had no presentation facility in 1992 so even if ITN was available to them it could not have been put to air (Studios were never required or expected to do anything like that as this was a presentation function) so much more sensible and practical to network Maidstone via LWT.

That's really interesting, thanks! Had TVS abandoned separate South/South East presentation by 1992 or did both services originate from Soton?

I assume Soton had non-Tower circuits from Maidstone, otherwise how did the programme go out locally?

Separate South/South East presentation did not last very long with TVS. Both services came from Southampton any way - there's a clip somewhere on the internet with a mis-timed opt.

Good question and I don’t know the answer to your specific point, my diagram only relates to ‘IBA vision and sound network rented from British Telecom’. Possibly TVS Soton might have used a BT protection circuit for the Comms playout from LWT? Norwich is shown to have only one in and one out and might/would face a similar problem? 

I very clearly recall during the Thursday morning network trailer exchange (so similar to the Saturday comms exchange) that sometimes the exchange would be paused for a few minutes occasionally awaiting some circuits somewhere to be cleared/re-configured indicating lines provision could be ‘tight’ at times. Sorry I can’t give much detail.

I should point out for completeness that there were additional rented circuits for the national distribution of C4 and S4C.

Edited to add. Presentation of the SE region from Maidstone did not last very long and by 1992 had long since been pulled back to Soton. I will ask my wife, she used to do it.

This suggests Soton and Maidstone/Gillingham/Dover were linked via London on BT SHF circuits

It also ties in with Mark's comment on http://txfeatures.mb21.co.uk/down_the_tubes/index.shtml

1983 or 1993?

Would be interesting to see that, is it something you can post online? Presumably there's nothing on there still in use?

1983. I can't see any of it being in use now since telly 'went digital' and of course other providers are available. The BT tower doesn't look the same with it's horns gone, same at Stokenchurch etc. 

It's A3 and I have no means to scan it in.
