You really need to go look things up and not argue about things you
apparently know little to nothing about. Bob Myers told you exactly
right about SD TV.

SDTV is not "first class"

In that case, what do you think "first class" means? You asked
about video as it appears in professional studios - unless you're
talking about HDTV broadcast, SDTV is all there is.

What about the color subcarrier sample rate? The horizontal frequency
sample rate?

Those phrases are nonsense. There can be different sample rates
used for the "chrominance" components vs. the luminance (i.e.,
go look up "4:2:2" and "4:2:0" sampling as opposed to "4:4:4"),
but you would never refer to this as the "color subcarrier sample
rate."

LCD and
Plasma do not require retrace since there is no scanning, just counting
off samples.

That is why plasma and LCD are better than CRT. In addition, plasma is
better than LCD.

Actually, this has very little to do with the relative performance of
these technologies. And before we start talking about which is
"better," you'd have to ask what "better" means. "Better" in what
aspect?


IIRC, HDTV is a tad closer to "first class" than SDTV. Again, I could
be wrong.

Since you have yet to tell anyone just what you are thinking of
when you say "first class," it's impossible to respond any further.
Do you mean the digital cinema standards?
