Thought it was a shame how it wasn't like the analogue switchoff when the continuity announcer said goodbye to viewers that were watching on analogue. This would've been nice to see especially on One and Two.

The difference with analogue switch off was that at that point there was two separate playouts fir both main channels

One announcer on digital and one on analogue At least it was like that fir a while

On 405 line VHF television the playout was different even if there was one continuity announcer back then. On UHF you had a 1 kHz tone but on VHF you had a tone around 480 Hz I think so the output could be split.

The bbc1 nightlight was a downscaled BBC1 HD with split links and overlays.
