You are right. I don't remember saying otherwise though. The YUV coordinate
system was initially proposed as the NTSC transmission standard, but it was
later replaced by the YIQ system because it was found that the I and Q signals
could be reduced in bandwidth to a greater degree than the U and V signals for
an equal level of visual quality. Come to think of it, what am I saying…
Aren't you the TV wizard?
At any rate, this is what I was saying when I was talking about the virtues of
D1 being a bit overstated. By the time you get the image on tape, it has been
reduced quite a bit from its original RGB form. Technically, I can compare both
D1 and JPEG as lossy compression. The differences are obvious and worlds appart
but people shouldn't discard "digital" alternatives just because they have
"JPEG" attached to it. It bugs me when people talk about D1 as the best
"quality" as in picture definition. D1's virtues are in being digital and as
such, infinitely (theoretically) reproducible and suffering no loss in the
transport process. As far as image quality goes, or amount of information
present in order to reproduce an image, it has less than what something like a
PAR unit would display. Or a laser disk for that matter. Heck, even less than
Hi8. The problem is that a tremendous amount of information sent to an analog
deck as a Hi8 or a LVR is lost on the way in and on the way out of it. And to
top it all off, once you reach the limit in bandwidth of what can be
broadcasted without violating FCC's regulation, you're done. I can't wait to
see the day we find ourselves free of NTSC and go all digital. Can you imagine
the kinds of things people will be bragging about? Thing is, you've got D2 and
D1. What's next, D -1, D -2, etc? <g>
Oh well, as usual I went way off again…
