[opendtv] Re: Demand for free DTV rising in Australia

The POINT!!! IS!!! that they are NOT proposing this in COFDM
countries, they are proposing it in the US of A because Congress, the
FCC and EVEN MOST BROADCASTERS show little interest in OTA DTV. They
show little interest in protecting this spectrum or testing to see if
8-VSB even worked in the beginning, in quickly taking 8-VSB proponents
statement that it was fixable and would be fixed forthwith in 2001.
Every action Congress, the FCC and broadcasters have taken (sans
Sinclair and a few others) screams "We could care less about OTA and
the viewers who do or might in the future benefit by it".

My POINT again was that it is in NO parties interest to CARE about the
OTA viewing public in  the US. Everything politically and broadcast
wise is skewed toward the large cash flows generated by cable,
satellite and now the Telcos.

The only hope I have had for a number of years was that the incredibly
successful numbers being generated by other countries with their
digital transitions would cause some less timid new Congresscritter to
see that they might generate some heat by pointing out what is all the
time becoming more obvious and will be over the top in your face by
the time of the transition. The 8-VSB and OTA in the US are dead.

"Digital TV in 20m+ UK homes

More than 80 per cent of UK homes now have digital television on their
main set, media regulator Ofcom has reported.

Ofcom's Digital Television Progress Report for January to March 2007
shows that household take-up of digital television now stands at 80.5
per cent, or 20.4m homes, up from 77.2 per cent in the previous
quarter.

The quarterly digital TV update also shows that Freeview has now
overtaken Sky as the most popular digital television service,
experiencing huge growth in the first three months of the year.
Digital cable TV, now under the Virgin Media brand, outperformed Sky
in the number of new subscribers for the first time since 2001.

Freeview is now the largest digital service, on the main television
set in 8.4m homes, up from 7.7m in the last three months of last year.
Sky by comparison grew its customer base by 32,020 in the quarter and
now has just over 8 million subscribers. Free-to-view satellite also
added 70,000 homes, taking its total number to 885,000."

Didn't we already know this (copied immediately below)? It's the problem
of IM3 distortion. Why make it sound like it's a brand new discovery? I
agree that use of white spaces is risky, and IM3 makes it even more
risky. This also holds for COFDM.

"The fact that more than one U signal can result in
interference, even when both U signals are below their
threshold power levels (measured separately), makes the
interference possibilities simply terrifying when
unlicensed transmitters begin to share broadcast spectrum
on Feb. 18, 2009. Stay tuned."

As to professional installation FUD, what is that trying to prove? Is it
any different for professional installation of cable and DBS? Any of
these guys can use Channel 3 as a shortcut, big deal.

As to the chicken-egg problem of scanning DTV channels initially, when
analog channels will no longer be there to help, how is that any
different with COFDM, and especially with low power COFDM? The answer,
obviously, is to use the various aids made available by the CEA (e.g.
antennaweb) or equivalent in other countries.

8-VSB is irrelevant in all of this. The problem here is unhelpful FUD
and hype.
