Was this the incident, where colour bars were accidentally switched in, during an interview with Robert Peston in the studio?

Does anyone know what the strange pattern at the end of this closedown clip is? (Skip to 5:19)

Edit: Just noticed that the Testcard seems to not want to stay on screen before that pattern appears.

Not particularly unusual- that's the "pulse and bar" pattern, was always the last thing to appear before the transmitters were turned off and the first thing shown after they were turned on until the early 90s.

As James2001 notes the signal contains (luminance) pulse and bar signals, but it also contains two other signals - a 50% luminance pedestal with a burst of 100% chrominance sitting on it and also a 100% amplitude luminance pulse filled with chrominance which was an unusual signal to see in itself, it enabled an engineer to assess chrominance to luminance gain and delay differences. These parameters were important in analogue days, the last two particularly over long signal paths. I suppose that’s why the BBC may have transmitted it after closedown - to assist engineers to assess long signal paths from television centre to wherever.

Is it normal for sound to be dipped on a channel? So far I've heard on Magic and 4Music that when it switches to the next video the first few seconds of that video is loud and then it is like they have turned the volume down their end.

It can be... by accident or otherwise.
Those sort of channels though probably run on an automated playout system so its plausible they've been set up to do that.

Doesn't look like that anyone caught it, but the News Channel seemingly crashed just before 9pm (or it might have been 10pm, I was channel-surfing in the minutes before both so don't remember exactly!). Frozen on a still that appeared to have been part of an animated graphic with the usual instrumental music playing in the background eventually fading in. No idea how it started or ended as a programme on another channel I was wanting to watch was beginning.

It was just before 10. It went from the weather to a still frame of a city skyline with a BBC News box (possibly from the numberless countdown?). After a few moments of silence, a headline bed was faded up. A few seconds before 10, there was a hard cut (it looked like at router level) to Reeta in B.

It’s doing that because recently they re-added transitions to C4’s music channels and for some reason when the transition is put to air it does that.

As mentioned earlier, the error from last night's 10pm News Channel junction, where the countdown was seen to freeze. For those who want to relive watching a static image of a skyline for several minutes.

Yes, apologies for not rushing to post it in here within an hour of it happening, but there's a lot to juggle in a busy day sometimes.
