I'm sure the standards converter manufacturers are crying in their beer over
the fact that the ATSC denied them such a nice new business!

If you see the sole purpose of DTV to be watching movies at home, then why are
we even bothering with this?  It would be one heckuva lot cheaper and easier
to just give everybody a 16mm movie projector and ship out rental film prints.

Well, I don't know who came up with these figures.  The computer industry
produces and sells no less than 40 million PC systems a year.  Clearly the
production capacity exists.  >>

CEMA (Consumer Electronics Manufacturers Association) came up with the
figures, which I've seen cited in a couple of different trade publications.
Even if you can compare a Mac or a PC to a (H)DTV receiver--I don't think such
comparisons are realistc--why should we expect the computer industry to stop
making those PCs that are doing so well and go into the television business?

sports and movies.  And, within those segments, only those viewers that are

By this logic, we should have stayed with monochrome TV, or radio for that
matter, since there's an awful lot of programming that would be the same in
black-and-white, or just plain black.  By my observations, once people get
used to SDTV, most won't be happy with NTSC again, regardless of what they
watch.  And once they see a few hours of HDTV, they'll wonder why everything
isn't that way.  Assuming we don't have an economic downturn this fall due to
events in Asia, I think DTV sets will go flying out of stores as soon as the
initial sticker shock wears off.

<< Being that stations these days run on automation systems based on timecode,

You'll be glad to know that there's now such a thing as "metadata," which
takes the place of timecode, and contains a whole lot more information
besides.  Assuming SMPTE can get the standardization issues wrapped up soon,
there should be no problems with automation.  I know it's quite a leap
compared to what we have now, but MPEG-2 means we no longer have video frames
in the traditional sense, nor do they follow a predictable sequence, so frame-
based timecode is useless anyway.

You mean like ATSC "Table 3" ?!?
