Technically it is only ~2.2x as long as the US Hostage Crisis in Iran in
remaining days for NTSC.

Remember that the US ABC Net ran a Iran Hostage day counter during the
program 'Nightline" -- and the counter ran for some 434 days appx.

Great idea. Another annoying distraction from the programming and way to
burn images into displays.

I believe that most TV broadcasters want to scuttle the turnover to ATSC.
Right now, most stations have digital broadcasts only because of the FCC
mandate. They are probably hoping that if enough of the public ignore the
cutoff, and the date (Feb. 2009) approaches, they can use the ensuing outcry
over lost TV to delay the turnover.

The prime example of this public apathy is the lack of demand for ATSC set
top boxes that will receive the ATSC signals for legacy TVs.

Do you have any figures comparing the number of analog OTA viewers to
those using cable and satellite? I would guess that only those viewers
would produce an "outcry over lost TV".

The numbers that were publicized over a year ago as the result of a
major FCC sponsored survey is that around %15 of households with a TV
are OTA only. However, there are millions of households which have cable
or satellite for the their primary TV(s), but have secondary TVs in
the bedroom, kitchen, basements which are OTA only. Those TVs will need
a converter box as well if they are to continue to receive OTA channels.
IIRC, the estimates were from 50 to 70 million TVs in the US are OTA
only, but some of these are now ATSC capable TVs.

With the FCC mandate about to kick on on March 1, 2007 for all TVs,
regardless of screen size to have an ATSC tuner if they have an NTSC
tuner, the selection of small TVs with digital ATSC tuners is going to
finally increase. The FCC mandate controls TVs shipped across state
lines, so after March 1, no chain can move new TVs without an ATSC tuner
across a state line. So expect big clearance sales on soon to be
obsolete small and portable TVs with analog tuners in February.

I expect over the next 2 years the more well off households will be
replacing the old small TV in the kitchen or bedroom for watching the
news or the late shows with much more compact flat panel LCD HD TV with
ATSC tuners and throwing out the old TV. This will cut down the number
of converters needed.

The major TV broadcasters are not going to scuttle the conversion at
this point. They have spend a lot of money to provide a digital signal
and running up electric bills and equipment costs to broadcast both on
analog and digital. It is not cheap to broadcast up to a 5000 Kilowatt
analog signal. The analog shutdown will reduce their monthly operating
costs, once they have gone to the hassle and expense of digital
broadcast. Some small market station owners have been dragging their
heels on offering a full power digital signal, but they are getting there.

The most likely source of any movement to delay the February, 2009
analog shutdown will the consumer interest or various public association
such as AARP. But even with a Democratic congress, I doubt if it going
to get delayed, except perhaps for a few months for some of the low
power and translator stations out there. Hurricane Katrina revealed the
need for new common emergency, fire, police and government communication
systems and that will only happen when the upper UHF channels 60 to 69
are taken away from TV broadcasting. Four of the 6 MHz UHF channels are
to be re-assigned to emergency services. The aftermath of hurricane
Katrina was a driving force behind Congress settling on the Feb. 17,
2009 date over a year ago.

I do think that the government and industry have done a terrible job
of publicizing and explaining the analog shutdown. But there appears to
be a growing awareness in the press and among the people at large about
the impending analog shutdown. Still a lot of confusion over the whole
thing, in large part, because most people have no idea how TV works in
the first place.

I have neither cable nor satellite. Personally, I refused to buy a
HDTV unless it had a ATSC tuner in it. My options were very limited
until last. I now have two HDTVs/

There is a demand for ATSC converters if the price is reasonable. One
TV store owner told me that the wholesale price of TV's increased
about $40 when the ATSC requirement started last year. Given that, I
think that the retail price of a converter should be well under $100,
but they aren't. I don't even know anyone that sells them.

I purchased a 20" HDTV with ATSC tuner in December for $400. That
price is surely going to drop after March, 2007. If the price of a
converter is $200, it seems more efficient to throw/give the NTSC TV
away even though it's only 4 years old.

No. And I wouldn't look for any cheap ones til the end of 2008. There are
cheap ATSC tuners however. I've got 5 in my PC's. The cheapest was $17.50.
All of the last 4 or 5 I bought were under $25.

True.

I was in my local drug store and happened to see the manager near their
display of small TV sets. I asked if the headquarters people had said
anything about the soon-to-be-obsolete TV's that were for sale. I had to
explain to her about the transition (and I think she was disbelieving the
whole idea).

I asked how they would handle irate customers whose TV's would suddenly quit
working. She said, "Well, if they still have their receipts, we'll give
them their money back."

Yeah, right.

Related: How many motor homes, RV's, camping trailers are in use in North
America? How many of these are being used in places where they have no
cable TV hookup? (Yes, TV isn't part of the RV experience to all RV'ers,
but I think most expect to do some TV watching.) Just wondering. They
can't all have satellite.

That box was primary meant to be used to add tuner capabilty to a tunerless

only.

Most RV camping is done in areas where local OTA analog TV either does not
exist or is extremely limited.

Most RV campgrounds have campground cable TV; and those that don't are
typically in remote areas where there isn't much (if any) local OTA analog
TV. Even in remote areas, the upper-tier campgrounds have cable.

Most RVers have satellite. Newer RVs are sold with satellite dishes on
the roof instead of TV antennas. At a campground, you see far more
satellite dishes than raised OTA TV antennas.

Bottom line: the number of RVers who depend upon OTA analog TV are a small
(and shrinking) minority.

In your dreams.

Mostly because people are buying new LCD TVs with built in ATSC tuners
rather than worry about a tuner for old, heat-generating, power-wasting,
space-consuming, toxic waste generating CRT TVs.

Nor is there much need for an ATSC tuner for a legacy TV today. The
legacy TV works fine to receive analog, and will continue to work fine
with cable or satellite. It only becomes an issue in 2009, and by that
time the products will have the advantage of two more years of engineering
progress.

The only need for an ATSC tuner today is for HD monitors which don't have
tuners; and the costs for today's ATSC tuners reflects that. In 2009,
ATSC tuners will be both cheaper and better.

I disagree with that for my situation. In San Diego, I can get OTA DTV from
the LA market most of the time with a good roof antenna, sometimes just with
a simple bow-tie. However, there is JUST ONE station from LA carried on our
cable system, despite its being a very big, very high-quality system. I
want my legacy TV's to be able to get LA at my whim.

People in or between other city pairs are apt to be of the same mind.

You should be happy that the US choose the 8-VSB (ATSC) system for digital
TV, and NOT one of the COFDM-based modulations.

Although there is no guarantee that you'll be able to receive ATSC signals
from LA in San Diego, at least you have a fighting chance. One of the
features of ATSC is its superior performance over longer distances. It is
reasonable to assume that equipment and performance will continue to
improve over time.

The various COFDM-based modulations used in Europe and Asia are all
short-range. I have digital TV coverage maps for Japan, and in places the
coverage range is as little as 10km (6 miles) from the transmitter. The
longest distance coverage that I saw was about 40km; that wouldn't even
get you out of LA!

You'll occasionally hear from cranks and crackpots who claim that COFDM is
"better" because it reportedly works better in cars or trains. Japan's
mobile digital TV craps out once the vehicle gets much above 20km/h; I
know this first-hand. Another crank argument is because of a silly
pseudo-test years ago, when one of the Crank Brigade had trouble using an
indoor loop antenna to receive ATSC inside a Manhattan apartment.

If the Crank Brigade had had their way, not only would you not be able to
get LA TV in San Diego, you wouldn't be able to get Orange County TV
either; Orange County would be a completely different set of stations
since you wouldn't pick up LA in Anaheim. The northern part of San Diego
County would be yet another market. So you'd be 3-4 markets away from LA.

Yes ATSC is slightly more optimised for distance, but at the same time
it NEEDS to be since you need a huge single transmitter to serve a wide
area. With COFDM DVB-T you have the benefit of single frequency networks
which can use multiple transmitter sites on the same frequency to fill
in all the blackspots in coverage with overall less power wasted.

It is reasonable to assume that equipment and performance
will continue to improve over time.


It damn sure needs to improve since ATSC was inferior from day 1.

The various COFDM-based modulations used in Europe and Asia are all
short-range. I have digital TV coverage maps for Japan, and in places
the coverage range is as little as 10km (6 miles) from the transmitter.
The longest distance coverage that I saw was about 40km; that wouldn't

Stop spreading BS. The coverage is only small due to lower power levels.
Here in Australia the COFDM DVB-T transmissions have adequate coverage
of 140+km (usually only limited by the height of the transmitter and
terrain obstructions) with viewers with high gain antennas can receive
it past 200km.
Have a look at the coverage map:

You're more than welcome to keep your inferior ATSC standard just like
your crap NTSC standard within U.S. borders (along with a long list of
incompatible standards and the imperial unit measurement system). The
rest of the world will adopt the best system for digital terrestrial TV
which is COFDM DVB-T.

You should be happy that the US choose the 8-VSB (ATSC) system for
digital TV, and NOT one of the COFDM-based modulations.

Although there is no guarantee that you'll be able to receive ATSC
signals from LA in San Diego, at least you have a fighting chance. One
of the features of ATSC is its superior performance over longer
distances.


Yes ATSC is slightly more optimised for distance, but at the same time it
NEEDS to be since you need a huge single transmitter to serve a wide area.
With COFDM DVB-T you have the benefit of single frequency networks which
can use multiple transmitter sites on the same frequency to fill in all
the blackspots in coverage with overall less power wasted.

It is reasonable to assume that equipment and performance will continue
to improve over time.


It damn sure needs to improve since ATSC was inferior from day 1.

The various COFDM-based modulations used in Europe and Asia are all
short-range. I have digital TV coverage maps for Japan, and in places
the coverage range is as little as 10km (6 miles) from the transmitter.
The longest distance coverage that I saw was about 40km; that wouldn't
even get you out of LA!


Stop spreading BS. The coverage is only small due to lower power levels.
Here in Australia the COFDM DVB-T transmissions have adequate coverage of
140+km (usually only limited by the height of the transmitter and terrain
obstructions) with viewers with high gain antennas can receive it past
200km.
Have a look at the coverage map:
http://www2b.abc.net.au/reception/fr...=2969&presdir=

You'll occasionally hear from cranks and crackpots who claim that COFDM
is "better" because it reportedly works better in cars or trains.
Japan's mobile digital TV craps out once the vehicle gets much above
20km/h; I know this first-hand. Another crank argument is because of a
silly pseudo-test years ago, when one of the Crank Brigade had trouble
using an indoor loop antenna to receive ATSC inside a Manhattan
apartment.

If the Crank Brigade had had their way, not only would you not be able to
get LA TV in San Diego, you wouldn't be able to get Orange County TV
either; Orange County would be a completely different set of stations
since you wouldn't pick up LA in Anaheim. The northern part of San Diego
County would be yet another market. So you'd be 3-4 markets away from
LA.

We will, quite happily.

We have quite a bit of HDTV now, and are thoroughly enjoying it. In the
Australian digital TV forums, you Aussies seem to be complaining a lot
about the lack of true HDTV...and reception difficulties.

Seattle, a third-rate US city, has 14 (or 16, depending upon you count)
digital broadcasters, offering 8 HDTV channels and 26 SD channels of
programming. Tokyo, a first-rate Japanese city, has only 7 (or 8). How
many digital broadcasters do you have in Australia, eh?

NTSC has better color (particularly green) than PAL. PAL was a clever
workaround for the inferior vacuum tube tuners prior to the mid 1970s.
With modern electronics, that phase change just steals bandwidth. Then
there's that flickery 50Hz, which is a lot more noticable than the extra
100 lines.

We don't use Imperial units. The similarly-named American units are all
defined in metric terms, and are different from Imperial units. For
example, an American foot is exactly 30.48cm (although for most purposes
305mm is good enough).

But it does **** off your manufacturers when they want to produce
something for the US market; they have to pay for a completely separate
set of tooling. That is only the reason why you care.

The rest of
the world will adopt the best system for digital terrestrial TV which is
COFDM DVB-T.


The Japanese, Chinese, and Brazilians don't agree. They choose a COFDM
based system, but it isn't DVB-T.

It's the NTSC vs. PAL vs. SECAM catfight all over again; and for all the
same reasons.

If the US had chosen DVB-T, Australia would have chosen ATSC. It's all
about protectionism.

The US market is the largest market in the world and is price-sensitive.
Every manufacturer sells cheaper in the US than in their home country.
Australians (and Japanese and Chinese and Europeans) pay more so that
Americans pay less. If American HDTVs worked in Australia there would be
one hell of a grey market importing cheap TVs.

Ever notice DVD regions? Ever notice how Americans rarely seem to care
about multi-region DVD players? We get them at a (much) lower price than
you. Even foreign-produced movies are cheaper in the US than in their
country of origin.

It was a nice flame you sent. Better luck next time.

I'm a bit off-topic with this next, but maybe you know: Some public transit

somewhere. It's news, weather and features, all fast paced and light. It
doesn't seem to have sound or to need it, but does seem to be motion video
and it seems to work OK, even at 50 MPH. It's only on a few vehicles and I

Can you shed any light on it? (I haven't done any research at the transit

I would hardly call it bit starved. With a 23Mbps transport stream you
won't get more than a 13-15Mbps HD video channel plus a 6-7Mbps SD video
channel plus a 1.5Mbps video programme guide plus multiple dolby digital
and MPEG audio streams.
Do the broadcasters in the U.S. transmit multiple SD channels plus a HD
channel 24/7? If they did they would also have a 'bit-starved' video stream.
We have a nice hybrid system with multiple widescreen standard
definition channels like the Europeans plus HD video like other markets
such as the U.S on the same terrestrial transport stream.

Really? The maps show the coverage of that single transmission site, NOT

Take these two overlapping sites for example:
http://www2b.abc.net.au/reception/fr...=5441&presdir=
http://www2b.abc.net.au/reception/fr...=5438&presdir=

They BOTH operate on the SAME frequency. You'll find that all the infill

It is reasonable to assume that equipment and performance will
continue to improve over time.

It damn sure needs to improve since ATSC was inferior from day 1.


Which is why there are far more HDTV broadcasters using ATSC than any

That will change dramatically when Europe and Asia provide more HD
programming using DVB-T.
This map of digital terrestrial standards shows that most of the world's
population is certainly not going with ATSC:
http://www.paradiso-design.net/revim...B-T_032006.gif

In the language of COFDM, "inferior" means "better".


If most of the world's population has an "inferior" standard that
provides lower cost equipment through greater unit volumes then I
suspect most end users would prefer that system.
Unless of course a certain standards committee bribes government
officials in that country to adopt a "better" standard that favours
domestic manufacturers and patent holders at the expense of end users.

The various COFDM-based modulations used in Europe and Asia are all
short-range. I have digital TV coverage maps for Japan, and in

Yeah, but since you can't have single frequency networks you need to
waste an enormous number of TV channel spectrum to avoid interference.

of 140+km (usually only limited by the height of the transmitter and

is a major metropolis. But when we look elsewhere, we see such maps as:

http://www2b.abc.net.au/reception/fr...d=148&presdir=


Yep, that transmitter covers the twin towns of Albury/Wodonga quite
adequately and matches the analogue coverage there for that infill
transmitter.
The main transmitter site for that area is a bit further south and
covers a much larger area:
http://www2b.abc.net.au/reception/fr...=5472&presdir=

OK, I picked an obviously dinky town. But what about Canberra, with
this somewhat underwhelming coverage area?

http://www2b.abc.net.au/reception/fr...d=885&presdir=


If you check the scale on that map the coverage area extends out close
to 200km (hardly underwhelming)

And what the hell is "adequate" supposed to mean? Digital either works
or it doesn't. There's no such thing as being "a little bit pregnant".


It means a typical house with an external medium gain antenna pointed in
the right direction will pick up the signal reliably. The signal can be
picked up much further than those maps show by using a tall mast and
high gain antenna.

Perhaps by "adequate" they mean "a signal occasionally shows up".

What happens when you open a refrigerator door? Or the furnace kicks
in. Love those impulse noise effects. Got to see them first-hand in Japan.


Broad spectrum impulse noise will affect all transmissions including
analogue/ATSC/DVB-T etc., that's why you use decent quality coax. I
happen to live North of Pakenham which you pointed out earlier and the
only time I've had signal dropouts or any interference was when
lightning directly HIT the transmitter site. I'm amongst the
overwhelming majority that couldn't fault the DVB-T transmissions. Sure
you'll here people whinge about digital TV in oz, but you should expect
crap signal quality if you use a rabbit ears antenna in some canyon.

You're more than welcome to keep your inferior ATSC standard just like
your crap NTSC standard within U.S. borders (along with a long list of
incompatible standards and the imperial unit measurement system).


We will, quite happily.

We have quite a bit of HDTV now, and are thoroughly enjoying it. In the
Australian digital TV forums, you Aussies seem to be complaining a lot

Pretty much the only gripe we have is that one of our broadcasters (Ch
7) considers 576p to be HD as a pathetic attempt to circumvent the
government requirement for all digital licence holders to broadcast in HD.
However Ch 7 have no interest in HD so they get by with the loop hole
that 576p is HD which ****es off a lot of viewers since they have the
rights to a lot of NBC and other network content.

Seattle, a third-rate US city, has 14 (or 16, depending upon you count)
digital broadcasters, offering 8 HDTV channels and 26 SD channels of
programming. Tokyo, a first-rate Japanese city, has only 7 (or 8). How
many digital broadcasters do you have in Australia, eh?


A grand total of 5 but given that our population of 20million is spread
out over an area the size of the U.S. the market can't sustain more tv
networks with the available advertising revenue. I for one would prefer
quality over quantity.
It's preferable to having 500 channels of crap like in the U.S.

NTSC has better color (particularly green) than PAL. PAL was a clever
workaround for the inferior vacuum tube tuners prior to the mid 1970s.

Interesting that you point out a better particular colour for NTSC which
stands for Never Twice the Same Colour.

We don't use Imperial units. The similarly-named American units are all
defined in metric terms, and are different from Imperial units. For
example, an American foot is exactly 30.48cm (although for most purposes
305mm is good enough).

And not surprisingly the countries that had PAL are going with DVB-T and
the ones that had NTSC are going in the direction of ATSC.

If the US had chosen DVB-T, Australia would have chosen ATSC. It's all
about protectionism.


Rubbish. The only highly protected market left is the USA. The US
government is a proxy for the wealthy lobby groups that line the pockets
of senators with cash so that their particular standard or technology it
adopted rather than what is best for the population.
Australia would never have gone with ATSC, we just followed what the
Europeans did just like almost every other standard. That's just a
result of having a history as a British colony WITHOUT a revolution!

The US market is the largest market in the world and is price-sensitive.


ROTFL. Is that what they're teaching you in Geography these days? You
might want to check on the population of China and India which are
certainly NOT adopting ATSC.

Every manufacturer sells cheaper in the US than in their home country.


You'll find hardware in China/Japan/Taiwan (where almost all electronic
hardware is now built) to be MUCH cheaper than in the U.S. thanks to
protectionist import tariffs.

Australians (and Japanese and Chinese and Europeans) pay more so that
Americans pay less. If American HDTVs worked in Australia there would
be one hell of a grey market importing cheap TVs.


You must be living in a fantasy land, we import equipment cheaply from
places like China where it's manufactured, not from secondary markets
like the U.S. where the manufacturing base has died.

Ever notice DVD regions? Ever notice how Americans rarely seem to care
about multi-region DVD players?


That's because you've been distracted by all the crap that comes out of
Hollywood to notice all the great content that comes from international
sources. Most Americans wouldn't bother with content if it wasn't in
English (with or without subtitles).

We get them at a (much) lower price
than you. Even foreign-produced movies are cheaper in the US than in
their country of origin.


That's only the result of price fixing by the movie studios and their
distributors. They charge whatever price a market will bear.
As a general rule I would much prefer a 576 line PAL region 2 or 4 DVD
to a 480 line NTSC version, but the exact choice would come down to
which version was mastered better.


It was a nice flame you sent. Better luck next time.

Technically the digital TV system is great in Australia, but some of the
existing broadcasters pressured the government to impose ridiculous
limitations on the what channels and content can be broadcast with the
digital TV services.
The requirement for simulcasting what is on the analogue channels as
both an SD AND a HD digital channel has only been lifted this year, but
the broadcasters still haven't made any changes to reflect this.
Most of the regulatory restrictions will only be removed in 2009. Until
then most viewers have little incentive to change to digital TV other
than improved picture and sound quality, there is no significant
additional content to warrant changing over until their old equipment
breaks down.

In the USA there is much greater incentive to move to high quality HDTV
over the awful NTSC 480 line analogue services, but most people have
opted for sat or cable based systems instead.

US ATSC conversion: with 700 some odd days until NTSC is turnedoff, you would think that US TV stations would run a dayly counter...

Good, we like it. The USA's HDTV broadcasting system is *light-years* more
advanced than any cofdm-using country.


Which is why so many people are watching OTA terrestrial HDTV in the
USA..... NOT.
The light years you speak of are an indication of how old and already
obsolete the ATSC system is. But don't worry it will only be a matter of
time before the standard is just a foot note in history just like the
long list of USA centric communications standards.

At least the USA was out there seting standards, unlike Australia.

Golly gee, most US digital TV broadcasters are also at lower power
levels.


I guess that lower power levels is only an excuse when it's COFDM.

Here in the UK the amount of homes with terrestrial digital had reached
almost 9 million (and growing!) six months ago http://www.tiny.cc/dymOd.

Set-top boxes can retail at under 20UK pounds, also virtually every TV
manufactured in at least the last 15 years (along with DVDs, satellite,
video equipment etc) is fitted with one to three SCART sockets, which when
used in conjunction with a standard lead will almost instantly convert it
into an RGB stereo monitor (it also controls w/s a/v switching) allowing any
digi-box to plug straight into any TV, therefore obtaining maximum audio and
video performance.

As regards transmission power the VHF spectrum for TV transmissions was
abandoned in the 1980s, local to where I live there are two UHF relay
transmitters serving tens of thousands of people with reliable multi-channel
digital TV reception, output power 20 'Watts' each.

And none of those homes, except the lucky few hundred within range of
the London trials, is receiving HDTV.

And none of them is outputting HDTV to its owner.

In the US, an overwhelming majority of affiliates for all six national
commercial-broadcast networks (CBS, NBC, ABC, Fox, WB, and UPN), as
well as the national public-broadcast network PBS, has switched to
HDTV via ATSC. Having begun this transition in 1998-1999, US is seven
or eight years ahead of Europe in terms of over-the-air/terrestrial
HDTV deployment and several years ahead of Japan and Australia.

*All* first-run half-hour comedies, one-hour dramas, and theatrical
movies on the broadcast networks, with the notable exception of most
reality shows (except American Idol, whose audience is probably as
large as every other reality shows' combined), have been shown in full
widescreen HDTV for some time, in many cases for years (Smallville
since its launch in 2001; The Tonight Show with Jay Leno since 1999
(!), etc., etc.) Other than the reality shows and daytime soap operas
(which will likely transition last because their inexpensiveness is a
large part of their appeal to networks, and new HDTV sets and cameras
cost money), the last remaining first-run categories that have not yet
yet fully converted over are syndicated shows and the morning and
late-night talk shows.

In terms of cable and satellite (the way 88% of US households receive
their television programs), each of the five major national
premium-movie networks offers at least one 24-hour HDTV channel. About
10 other 24-hour national HDTV cable channels exist.
