If so, my understanding is that in D land TV sync is used to
disseminate the official time and frequency standard, and this extends
to the ZDF satellite transmission too. If so you will have Caesium
accuracy and a nationally traceable standard. >>
That would be tremendously handy. Where I live, I doubt that we have direct
access to the signal. A little too low on (or below) the horizon.
Wish we did have access, though; 15625 being 1MHz divided by 64 is a
beautiful thing! In the American system, our sync-to-standard-frequency
ratios are a little messier. The color burst frequency is defined as
63/88ths of precisely 5MHz, with horizontal sync being 2/455ths of color
frequency. Lovely combination of ratios, eh?
