The conversation is broken (in that I have some emails still in my folders
and some on the server, but the specific cost remark is only alluded to)
hence I suggested a site search to Rob.

However that?s all a bit irrelevant if you now have the solution you
referred to in the original 'conversation' we had. I do have an old email
response from someone else on the list asking you for a YouTube demo if you
have one? ;)

Can't seem to get your previous temp home link working and can't see this
solution on your homepage - am I in the wrong place? Sounds very
interesting.

I have no idea what remarks of mine you're referring to here.

In any case, what you want is something that is fully synchronous to the
source, i.e. something that samples every source pixel exactly once.

No commercial solution will do this, since none of them know the BBC pixel
clock. What they will do is sample pixels at some predetermined other
frequency, then discard, duplicate, mix and interpolate pixels (or even
frames) to arrive at the desired output resolution and frame rate. This
process gives rise to several visible artifacts.

My solution does a lot better, since it is able to sample every source pixel
exactly once, even in the absence of an explicit pixel clock, by some
special trickery.
