The antenna part has me confused. I cannot find this answer - but I
guess I am correct by my own use. ATSC is simply a different format
(compressed MPEG2) sent over the UHF spectrum. Right? So any UHF
antenna will pick up the signal - nothing needed special? That is
what threw me.
ATSC is more then just sending MPEG2 over the air. ATSC is a
modulation method independent of the compression scheme. The FCC has
mandated MPEG2 but virtually any type of data can be sent. If you are
interested, see www.atsc.org for the specifications.
You are correct, there is no such thing as an HDTV antenna; but an
antenna designed using today's tools is most likely to be a better
design then even one designed 10 years ago. High-speed computers have
greatly aided the design effort. Regardless though, marketing has
always hyped the advertising. Antenna manufactures (not all, but many)
are notorious for making false or overstated performance claims; such
as gain, return loss and frequency response.
I was not trying to say anything more - just that NTSC is a standard and
ATSC is a standard - they both move on the ether and arrive at my home
with the help of lots of folks.
But the average folk could care less WHY water ripples if a rock is
dropped in a standing water of glass, than it just causes a ripple. And
they think about it less than why do I need Coffee for breakfast - if at
all.
Most people want only to know if the electric works. The HDTV people
fail because of money. Over-the-Air does not transport as far as Cable,
and even local - most people view local TV over Cable.
The chances of most people viewing how nice Over-the-Air HDTV is
miniscule. But if computer folks can be shown it is easy and cheap -
folks can view nicely in our home for nothing.
