I don't believe this is quite correct. The VDG outputs a luminance
signal and two color signals , phase a and b. I believe this amounts to
describing a color space with 3 components. I am confident these could
be converted into RGB with little or no signal loss.
If I ever find a job my scan doubler for the tre is also going to
support my deuce. The model deuce I have, a -3026, has ... terrible
video noise. Anybody else with this model have the same problem? And it
is not because of its age. It has always been bad.
P.S.: The VDG also outputs a "chroma bias" but I don't believe this is
an independent signal component.
