As long as the lines of resolution don't go over around 500 then it is still
in the realm of NTSC.  NTSC can supposedly handle 500 lines of resolution.
Most VCRs only provide around 280-300 depending on the VCR.  S-VHS supposedly
gives 400-450 lines, ED-Beta around 450-500 and LaserDisk around 400-450.
I suppose you can cram as many pixels on one line as you choose as long as the
total lines don't go over 500 lines and don't go out of NTSC aspect ratio.
Colors aren't a problem as NTSC can produce about anything that any current
PC can produce.
     The one paradox about S-VHS.  Since current broadcast television produces
only around 200-300 lines of resolution (broadcast degredation?), how does one
get a 400-500 line resolution tape of anything?  Well, you either buy a
prerecorded S-VHS tape, a LaserDisk, or use a Videocamera to your S-VHS
recorder.  Or you can tape a laserdisk.

Hmmm.  HDTV, yes something that all computer manufacturers need to start
considering.  It's not far off before those monitors will begin hitting the
shelves.  The one thing I worry about.  Since the FCC and other federal
federal agencies haven't adopted an HDTV format yet, let's hope that NeXT
hasn't jumped on the bandwagon TOO early.  There are many proposed formats
with probably several refresh rates.  It is still worthwhile to start thinking
about HDTV for the future of computer monitor standards.
