Maybe, it has to do with the boxes I was looking at being ADAT boxes.

So with video master the audio clock would be derived from the colour
sub-carrier then? (horizontal seems kinda low) It seems odd that for a
non-video source an even ten based frequency would be used rather than
something like 1.536M for example, that divides evenly.

1024 channels of routing seems like more than anyone could need, but I
remember terminating a wall full of audio lines at one of my first jobs in
a small town radio station, so I am sure there are places with more than
one of these boxes.

So AES10 (MADI) should be just as free? Or am I missing something? I know
there is a charge for the documentation for both AES 3 and AES 10, but is
there a use fee as well?
