I personally think that the ITV Schools 30th Anniversary slide was 8probably being transmitted from Channel 4 - they had been supplied with two slides in the Summer of 1987 when they broadcast the schools programmes on behalf of ITV during the elections and another event on ITV, and must have had it still to hand in presentation. Whatever had happened allowed them to show the slide and caption, and play music (on of their testcard tapes) but not broadcast the programmes. This is just guesswork
It's all just guesswork!
Thing is that if they could transmit that slide, why not any of the others they'd have on the same stills store? Something more up to date rather than one they used for 2 days years earlier? Hence I think it could be from an ITV centre. They'd probably have that schools slide knocking around, but not the recent ones.
but why would an ITV company take over control of Channel 4 - they would be busy enough dealing with their own output.
That's how disaster recovery back ups work, you have an arrangement with another organisation (or elsewhere in your organisation) whereby they will provide facilities to help you out if the poo hits the fan. People muck in to help.
In this case an ITV company would be an ideal location - they co owned C4 and each had a facility to insert their ads... if its off air anyway they're not doing anything else!
As I mentioned before, Channel 4 used theirs in the 2000's, that location was a company involved in TV but not a broadcaster. Channel 5 used to have their DR at Red Bee in White City (presumably not now as their playout is now there) LBC and Talk Sport had DR arrangements despite being rivals, one morning their breakfast shows came from studios next door to each other as Talk Sport's facility was out of action
In broadcasting that could be anything from a full spare playout suite or studio to a bag of tapes* Old linear edit suites were quite handy at being repurposed to makeshift playout suites - they had stills stores, microphones, tape machines and audio mixers already. That's what the BBC had prepared at Pebble Mill many years ago
*I worked at a satellite channel many years ago and we literally had a bag of tapes on a shelf for another satellite channel along with instructions on what to do and who to call to get them on air - plug this to that, get MCR to route X to Y and get BT Tower to route our local ends to the ones normally carrying the channel. Crude but its just about keeping something on air
