[TLM - The answer to this first series of questions is that Congress is
going to continue to slap them around unless they keep promising that
they'll do at least some form of HDTV. Now, if you are one of the
broadcasters (and there are quite a few) that believe in progressive
emissions formats, then it leaves you little choice but to emit your new
congressionally-required HDTV programs in 720P, given that those are the
only culturally acceptable progressive HDTV formats.
If you take the time to read ABC's and Fox's statements, you will find that
their research has led them to conclude that progressive emission formats
also compress better, produce a better quality delivered picture through an
MPEG-2 compression channel, and better match all of the emerging display
technologies - better quality delivered to the consumer than, for example
1080I through the same fixed-bitrate channel.]
Because the computer hardware and software giants are really really really
pushing hard for it. You can control the content if you can control its
form and display.
[TLM - That's utter nonsense. You may have failed to note that
Matsushita/Panasonic, ABC, Disney, Fox, News, NDS, Bell Labs, TI, NTV,
Gennum, Leitch, some PBS management, and even some parts of NBC and CBS are
also in favor of progressive transmission formats. You've also probably
failed to notice that Fujitsu and others have started announcing 720P and
768P flat panel display technologies. Yes, CRTs are somewhat cheaper right
now, and they can produce 1080I at a lower price point than 720P native
(albeit maybe at lower actual resolution), but I wouldn't be my business on
that remaining status quo for very long.]
And some of the broadcast networks (all of whom are losing overall viewer
share at an alarming rate but are in public denial about it) are in such a
huge panic that they are willing to let the wolf in the door and are
willing to push its agenda, hoping against hope that it will not, in the
long run, tear their throats out, which of course is exactly what it will
do (dramatic, ain't it?).
[TLM - You don't give America's broadcasters much intellectual credit,
engineering sense or business acumen do you...?]
