"The cable operators will use the promotion to play up the
benefits of high-definition television, while pointing out that
only cable, not rival satellite–multi-channel services, will
carry the Olympics in high-definition this year."

Cable can apply "rate shaping" to the OTA HDTV they carry:

"It then analyzes the MPEG-2 transform coefficients – the
mathematical information that MPEG-2 uses to describe the video –
and rounds them off in a process called requantization. This
process achieves further bit-rate reductions. But requantization
is a lossy process and, under stressful conditions, it may result
in artifacts."

Wouldn't it be nice if everyone could receive OTA signals without
putting up antennas or two?

Why is the US sticking to a modulation that denies many of its citizens
the use of their OTA spectrum? In Japan cell phones will receive DTV
broadcast with stubby ONE inch antenna. In Japan an Europe in fact most
of the world DTV sets will include internal antennas that are not even
visible that will work just about anywhere even in subways.

OTA signals are really nice to have. Everyone should be able to use them.

IMHO, the technique of "re-coding" the HDTV video datastream to
reduce the data rate will be abused by cable, satellite (and DSL
and AC power line) DTV distribution systems.

I wonder how many video artifacts the average HDTV viewer will
put up with?

Because you're a well known lunatic and everyone knows that the longer
8VSB is around, the crazier you will get. When you get institutionalized
with saliva dribbling down the sides of your mouth, then a change will
be considered.

Meanwhile, come on back to the AVS forum. Sign on as Gear 2. We'll be
happy to show you a real good time.
