Not quite perfect - there's a little bit of ghosting there, which you can see quite clearly on the verticals lines.
I didn't stay up all night, I usually fall asleep by the time BBC1 finishes the test anyway, but I recorded the tests. On my tape, there's a clean cut back to N24 for a few seconds (long enough for you to think they've completely finished), then a messy jump back to TCJ and back to N24 again after another few seconds. Is this how it happened everywhere else? My signal comes from Mendip.
Well those U-links don't get cleaned very often! The change back in London would have been a little tidier, and also about 15-20 seconds later.

Same in London (obviously!) but Ceefax still appears to be on air here in London - I wonder what will happen on BBC2 Digital if they cut the teletext signal during these tests (as they have done in the past) on analogue, as isn't the generator just an off air receiver tuned to page 152?

Yes, very odd return there, flickering between TCJ and N24! But we're back - and that about wraps it up.

He was talking about the BBCi message that is used on P100 on all digital platforms. Digital platforms don't need generators as they don't broadcast the VBI. The data files for the teletext page are broadcast with the MPEG video stream, and then a generator on the STB's put it into the VBI before passing it on to the TV. Therefore I assume this message would be unaffected, as the data file won't be interupted.

I think he was actually referring to the fact that BBC2 digital was broadcasting pages from ceefax during the tests.
Meaning would the bbc2 digital screens go blank as they're receiving their teletext signal from off-air?

Oh right, sorry, I see what you mean now. It's not off air, it's a generator with the data stream directly from the department responsible for Ceefax.

For those who didn't see it, or want to see the very messy cut from News 24 to the card (although that might have been just Sandy Heath doing that), here's a 1 minute video. Nothing interesting really.

Can I just say that no matter where I move the player position thing it always starts at the beginning, and doesn't move when playing.
Was the "speaking clock" new to these tests?

The speaking clock was introduced last year.
I notice that this year (from that clip) that the clock only did every ten seconds - last year it did every five with a small pip after each one IIRC.
Yes, I think it was a different clock this time.
