So they are. I guess I was expecting that to be the last thing they showed before changeover - as I remember it being in the very last years, maybe from the automated switch onwards? Definitely with GMTV the last thing you would see would be their "See you tomorrow..." slide, sometime appearing with adverts either side.
The eggcup is there. Before the trail.

If you're a member of the MHP Private Parts someone has uploaded the last IBA Bulletin on ITV, which appears to be in Spring 1983, as they describe that they conviently fitted into the gap between TV-am ending and ITV starting.
I do believe you are right about ITV and C4 simulcasting engineering announcements but with the 5.45am edition that could have been later on, ie probably 1989/90 around the time when C4 started breakfast programmes.
They started simulcasting it on ITV and C4 from 1983, and eventually it ended up at 05:45hrs. The simulcast on ITV and 4 lasted quite a while, because the programme obviously broadcast notices of the C4 expansion project, so dealers outside of C4's transmission areas still required to see the programme !
I think it transferred to C4 only around 86, (still a year or so before the last relays were equipped for the channel).

Ah, yes I think you're right. I do recall a repeat showing of IBA EO at 12:15hrs on C4. That was certainly in place by 1984, can't remember when it ceased (it would have been the extension of programming hours that would have killed it)

From what I understand it ended in July 1990, shortly before the IBA disbanded into three organisations, the ITC, the Radio authority and NTL, the latter being what the transmission side of the IBA became. From then the NTL was a private organisation so they couldn't really get their slot on TV. From what I understand the the 12.15 repeat ended in 1987 when Channel 4 started showing schools programmes.

How could they use the switching gap for Engineering Announcements while BT were replugging things?

That's what I've been wondering too ?
If you look at that You Tube clip, there are two versions of the same IBA slide, one at the end on TV-am's transmission, the other at the front of Central's. However at no point is there a splat, or loss of sync, so it's hard to determine what source is what, everything is nice and smooth with fades to and from black ?
I can't remember what happened immediately before or after the IBA EA prog, with any switching splats etc ?

Indeed, Engineering announcements was also moved from its 09:15 slot to an 08:10 slot in September 1987, to make way for schools programming, which were the first "billed" programmes on each day, until the channel 4 daily started in 1989.
Which leads me to another question, did EA ever get a same day repeat on ITV?

I assumed the fade is the edit for time that the uploader made

I wondered whether the arrangement might have been a bit like a BBC soft opt. BT Birmingham sent the TV-am feed on to Central as well as directly to the transmitters on the usual local ends used for incoming network programmes. Central genlock to that feed and put it on their main output. BT switch the transmitter circuits to Central, and once they're in circuit Central can cleanly mix through black to their own slide and music.
Pure speculation of course, and you couldn't imagine them going to the trouble these days, but back in IBA days they might have made the effort?

They state "We've edited that interlude down, but left in the switch from London to Birmingham."
The clip was uploaded by Transdiffusion who are usually pretty good at respecting the important details.

Sounds plausible ! I was living in Plymouth at the time, I didn't often get to see the Tuesday (or any) morning broadcasts, so I can't remember how TSW /Plymouth BT dealt with the switching locally.
One important consideration (by then) would have been to maintain the Oracle data stream, so I'm sure that caption was either originated (or routed through) one of the programme companies at every stage. The IBA didn't have a data bridges for the 'local' cap gens or EPT1 gennies at the Tx sites. They were always broadcast without any VBI teletext.
