(Not really trying to followup, just couldn't seem to find a "vnews"
command to just plain POST an article...)

I am interested in a fairly complete description of the current NTSC
broadcast video standard, including carrier/subcarrier frequencies,
bandwidths, actual timing parameters (e.g. H/V retrace times, etc.)
as well as calculations/estimates of best/avg./worst case resolution.
If any of you netters know the numbers or can find 'em, or if you
can tell me where to look, I'd consider myself a better person for
having the information.  I'd also like details (if possible) on the
proposed high-definition standards I've heard so tantalizingly little
about recently.

TIA -
