The test card doesnt look like a tower one but was this another BT Tower failure?
The router at BT Tower is controlled by their bookings system. You want a circuit? You have to tell them what times you want. Get your times wrong, or your event overruns and you don't extend it? Colour bars for you.
They change their test pattern generator from time to time, but the concept has been the same for a couple of decades, and has been responsible for quite a few of the breakdowns featured on this thread.
("Facility Line", as mentioned on the bars here, is a BT product name - it's a vision circuit between two sites. It can be direct between two broadcast sites but is usually from a broadcaster into the router at BT Tower)
For those who weren't quite patient enough to sit through the silence in that clip - skip ahead a minute for a bit of Bruce Hammal and some Sky Bassophere, natch.
