Discussion on OpenDTV about testing of COFDM an 8-VSB

A report on the MSTV faked test of 2000 and a witness to the REAL test
conducted by Sinclair in 1999

Sounds the same. These tests were also in Rosslyn at a five-foot

Where did I say "indoors"? See above. All tests were conducted OUTDOORS.
Those of us who participated in the old Sinclair trials would be hard
pressed to come up with one site that failed.

Mark replies...
We wenr indoors. Again, all of these MSTV tests were OUTDOORS. Some of
us went in reinforced concrete and steel buildings. (reffering to
Sinclair test)

As I'm sure you already know, there was only one transmitter, switched
back and forth between 8-VSB and COFDM.

TTFN,

Are you talking about BOB or yourselves. BOB rants and you rant, I am not

Yup, I rant.
You and I (and others) post here to discuss our deployment/enjoyment of
HDTV.
Why do you think Bob posts here?

Strange. I live in a suburb in a very hilly area. Multipath makes most
OTA analog reception intolerable, a fact which the cable company exploited
for years (until their prices went higher than satellite). I'm only 8
miles (and two hills) from the tower.

If multipath broke 8-VSB, I'd expect DTV not to work at all.

Yet OTA DTV here has none of these problems. The only remaining DTV issue
is that the local ABC channel seems to have a directional UHF transmitting
antenna that aims none of their signal westward. Oh, and FOX is still
broadcasting in 480p (but they say that's getting fixed).

Being a semi-rural area, we do have lots of stuff generating the type of
interference that is reported to be likely to break COFDM. Generators,
chain saws, compressors, pumps,... you name it, we have it.

Bob probably has his motives, possibly he is just obsessed but more likely
there is some financial gain etc. that he perceives. For all I know he
could be partially right certainly there is some evidence that both methods
have strengths and weakness. It is fairly obvious that in mulitpath CODFM
works better (suburbs, cities, hilly areas). On the other hand long haul
flat plain areas say 50 miles from transmitter 8VSB has an edge when there
is impulse noise. This has been well established for a long time. Most of
the rest of the world uses CODFM (DVB) and they probably have good reasons.

However, the Bob haters only make there own rants or ridiculous claims that
does not further any rational discussion. For that matter what Bob says or
you say has little effect. The FCC is unlikely to change from 8VSB, it
would be politically disastrous at this point. After forcing 8VSB tuners in
TV's and forcing stations to spend the money, I cannot see them making a
change. It makes little difference anyway ==>> I am looking forward to
buying an STB that supports digital cable which of course has little to do
with 8VSB or CODFM. The only reason I have antenna currently is to play
with HDTV. When cable starts to support it, the antenna and 8VSB will be of
little concern. As for mobile TV, the future appears to be satellite not
CODFM or 8VSB

As for Bob, it is sort of like the signs at yellowstone national park. They
telll you not to feed the bears or leave garbage out that will attract
bears. If you feed Bob, he comes back more often.

Actually, your statement above isn't quite correct: 8VSB has an edge
when there is impulse noise, even when less than 50miles from the
transmitter. Please be more precise when you make semi-technical
claims. I am actually neutral on the modulation scheme itself, but
when making comparisons I look at the ENTIRE environment.

If you take any statement without looking at (and understanding) all
of the previous context, and you make comments against 'Bob haters',
then perhaps you are making judgements out of ignorance. (I
have seen some VERY QUESITONABLE and overly emotional comments
from you, where you make incompetent assumptions -- please
quit judging others.) I doubt anyone 'hates'
Bob, but many people (including me) have proven over and over again
both Bob's technical inaccuracy and also Bob's alterior motives.

If you misunderstand the understandable frustration as 'hatred',
then that perception is likely misguided. If you are an HDTV
lurker (not been involved in HDTV off/on since 1986), and haven't
looked at the entire context of Bob's nonsense (including the
AVS forum stuff), then your judgements aren't necessarily well
balanced.

You'll seldom see my statements as being 'pro-8VSB', but rather
looking at the alternatives. Those who compare 8VSB vs. COFDM
on purely technical basis, then that is also fallacious in the
regulatory/political environment of the US and considering the
'Ferengis' looking to further pollute our public atmosphere with
blip-verts on mass transit.

Current MSTV test of the latest 5th generation 8-SVB receivers show
about a 65% good reception rate. So you are in the lucky 65%. COFDM in
Berlin is receivable with indoor antennas at a 98-99% of the time in the
coverage area. At the NAB conference in Las Vegas Zenith would not use
indoor antennas that they had in their possession though they had large
floor to ceiling windows facing the transmitter site seven miles away.
They used a roof top antenna. Why? Simple an indoor antenna would have
been to risky. Same story they told at the 2000 hearings in DC while we
all watched Sinclair parade around a simple rabbit ears and place it on
the witness table with no loss of signal. If Zenith had tried that with
their Silver Sensor they would have lost reception in an instant.

In OZ they recently did a test where they received HDTV mobile while
driving along the expressway surrounded by other vehicles and trucks
without having any impulse noise problem. And they were using a non
directional omni antenna. Can you even imagine 8-VSB dong that? No.
8-vSB couldn't even handle the multipath with the omni antenna sitting
still.

Again arguing that 8-VSB works because you are in the lucky 65% is not
valid. We all want to use our OTA spectrum to receive DTV OTA. There is
a modulation that permits at least 98% to so receive. It is a crime to
use a modulation that disenfranchises 35% of the population.

I stil get the distinct impression that you blame people who support COCFM
(like Bob) as delaying the transition or causing problems with the
transition. This is hardly the case. Ther are many regulatory, money,
copyright, tehcnical issues that are causing the rel problem. The
transition probably will not occur for another 4-6 years and only because
the government wants to get the spectrum to sell.

So if you feel that you need to rant about Bob because he is hindering the
transition you are simply wrong.

You are the one that is always judging. Making comments that you know so
much and that nobody else knows anything.
That you are always right. When you make ridiculous statements it always
true. When other like me refute them we are being emotional and making
incompetent assumptions. Quite frankly I have said it before, but you still
dont get it. I regard you as no more competent than Bob and have no more
knoweledge than he does. If what you say is valid then what he says is
valid.

The issue isn't all or nothing. It is apparent that you want to
downgrade people like Bob's complicity to NOTHING. If you don't think
that the FUD that has been espoused by Bob and Sinclair hasn't had
negative effects on the planning for HDTV (hardware and broadcasting),
along against the gunshy consumer, then perhaps YOU need to
understand psychology better.

In this forum, you'll notice that the genearally worst FUD problem
is Bob (and his apologists.) Remember: I am an HDTV advocate -- I
have NO other competing interests like multi-channel pay per view
(with minimal SDTV quality) or mass transit blipverts.

Look at yourself. Please refute my claims one by one, and quit
over-generalizing like the idiot that you really are. (Remember,
I have been around HDTV since 1986, and really understand almost
the ENTIRE context.)

Newbies like you who know 'everything' are the WORST -- even
moreso than Bob. At least, Bob isn't a meddler, but has a real
personal interest in usurping the originally planned for HDTV
spectrum.

My reception is also excellent. Of course, My NTSC reception is more
multipath and noise distorted. Given 'normal' people who I know have
tried, reception has generally been successful. Please ignore the
low VHF reception problems, where COFDM is likely much worse.

Richard, I am still waiting for ANY statements that I have made
that we can discuss. Why don't you open the issues up for discussion
instead of complaining?

If you simply want to complain, then please complain and whine
elsewhere.
