"There is a satellite problem somwhere - The satellite isn't working right now.." Rolling Eyes

Thanks for the You Tube clip of Live Aid (for Africa) falling off air. I'm now facinated by the total lack of back-up.
So, I take it everything was routing from Wembley/Philly into a gallery at TVC for onward transmission to the UK (and therefore, I assume out to Eurovision), so, obviously the instruction if London fell off the air was to 'hit the US feed' and they'll fill the time - didn't quite work that way.

Wonder why the gallery didn't get a replacement VT item on sooner, rather than leaving us with the hapless Amercian stage host, having to keep the crowd placated by telling them a frankly laughable excuse?
Something like that probably wouldn't happen today

I sort of presumed they were being shot on PetoScott cameras which again I also sort of presumed fed into the Philips range of cameras - any thoughts?


Ha ha! In reality the Peto Scott cameras didn't really exist. It was a badge engineering job really.

The Peto Scott cameras were effectively Phiips LDK3s, but because they were bought from Peto Scott they were 'British'... I'm sure there were BBC modifications and there were both PC60 and PC80 models - but AIUI they were effectively LDK3s. SVT in Sweden used their LDK3s well into the 80s...

They generated nice pictures - but had hefty (dual in some cases?) multicore cables.

Have a feeling the first colour handhelds the BBC had - the Philips Minicam (developed by Philips Norelco in the US ISTR) - were re-badged as Pye for the same reason.


I should probably re-phrase this a bit. Philips Plumbicon cameras were effectively a response that Philips Norelco in the US took to the US dominance of RCA in the camera marketplace. As RCA and NBC were commercially linked, CBS in particular wanted a decent camera from someone other than RCA (as they didn't want to give money to their rivals...)

CBS therefore worked with Philips Norelco (i.e. North American Philips) to develop the PC-60 camera.

In the UK the Philips Norelco PC-60 was re-badged as a Peto Scott PC-60 (as the BBC always wanted to 'Buy British' at that time, in Europe I think it was re-badged as the LDK-1... There was also a PC-70 and a PC-80. One of these became the LDK-3.

Good article in Dutch here : https://www.omroepmuseum.be/index.php/geschiedenis-radio-tv/televisie/24-toestellen/televisie/studiocamera-s/36-de-camera-die-een-revolutie-veroorzaakte

They mention that the input from the BBC and CBS helped the cameras properly evolve.

(From memory the LDK-1/PC-60 needed two multicores, the LDK-3/PC-70 and PC-80 only needed one?)



A quick google seems to show the PC70 with a single core too. Thanks for your info.

Edited to add: Here's a link to a 'Nana' show credited as being from 1968 - maybe this was the one I saw on BBC4? Although its the usual Youtube quality I think you can imagine what the original TX was like. Not my kind of music though!

I was watching a 'University Challenge' show a couple of weeks ago and marvelled at the pictures. The technical quality was excellent of course, but what caught my eye was the lighting. To my eye the pictures almost looked 3D in nature due to the expertise and skills employed by the lighting department. I think similar of the 'Nana' pictures. Lighting - much underestimated by the general audience, but perhaps it should be if its done correctly.

To be honest, from the point of view of the Americans, they probably did assume it was a satellite problem initially.
That said one of the You Tube clips has a US radio station's version of events, at 03:15 the feed fails, but the radio station fades up another alternative feed (I think there was a longer gap of silence that's been edited out) The US radio presenter at 03:48 informs us that the BBC are having power problems, and they will stick with the (inferior) feed.

I know someone that was involved with the Wembley OB. There were a number of less that optimum circumstances surrounding the broadcast of the event, firstly it was a production mounted by the 'Features'
dept of the Beeb, not Sports/Events, who would have had much more of a handle on making contingency and resilience plans, and secondly it was (of course) all thrown together at short notice.

I don't think the BBC (or anyone else) was the host broadcaster as such. There was a BBC feed from Wembley that was distributed internationally, and another from Philadelphia that was separately distributed internationally, and it was down to individual broadcasters to flip-flop their presentation between the two venues themselves ?

It looks as if Net 2 pres simply cut to the US feed (where the crowd had been watching the Wembley feed in their screen(s). Nothing else they could really do, as their own event pres was also being mounted from Wembley (in the stadium studio) which was also dead in the water.
