Gernot,

I don't have a pressing need to use CIE & Co, not yet, anyway.
I just wanted to understand this business at a basic level.

Thank you for the clarification re Cb and Cr.
I suspected that they have no physical meaning. Speaking in terms
of Math, it is only natural that you want to be able to invert your
transformation matrix, but this alone does not determine the
remaining coefficients. Here comes the explanation: "by tradition".

However, when you fix the coeffs, then there are "consequences",
so I thought that there had to be some practical considerations
in their selection.

Your report is beautiful, and though I don't know about your intended
readers, I would add a few definitions (white point etc), so that
one would not have to start reading somewhere else.
But that's only the former lecturer in me speaking...

Again Gents, this was a lively discussion, it would be nice to see
a few more of them in the future!

Thanks

Miklos
