[interference effects on digital TV signals]

I was surprised that the "digital cliff" is err "wider" than expected: it's not so much a now you see it now you don't but a varying disruption which shows up as mass blockiness. I had expected a more binary works/fails, the current atmospherics show up as unreliability that comes and goes (prob. due to fading in and out).

As you say, the fact that with analogue signals the cause is much more visible whereas in the digital world a wobbly BER bar is not as much fun!

This is because digital works a bit differently.

I'm no expert (Pye VT14 circa 1960 was my forte), but now they use a sort of differential signal to save bandwidth by not transmitting picture areas that don't change (much)from frame to frame.

Total signal loss would give a perfect still frame.

I don't know the details, but it's the basic reason
