The video data. Either you have to try to come up with some way to map
color components to signals/pins (and even cycles) or you just enumerate
the formats and keep adding to them when new ones appear. There's h/w
that allows the former, but in the end you have to interoperate, so
enumerating the formats is probably enough.

I am hoping, too.
