A few years ago I had a JVC 'multimedia' TV that was basically a 20"

be great now. I wish I had saved it instead of selling it.

We had several of those at work for compatibility testing, IIRC every
one of them failed.

I repaired a HV shutdown problem with the one I had. I can't remember
what caused it, but it was something minor.

NTSC will be with us longer than anyone wants to admit.

I'd like to believe that, but I'm afraid that the FCC has other ideas.

I know I won't be buying an HDTV receiver any time soon, they're still WAY
out of my budget. I can buy a 27" NTSC set that looks just fine for what's
being broadcast for $175, it's 10x to 12x that for the cheapest HDTV ready
(without the HDTV tuner) set. Damn if I'll pay more than a week's wages for
a TV set, there's just nothing worth that kind of scratch to WATCH on them.

The DTV standard for over the air broadcasts requires a good and stable
incoming signal from the antenna. In the RV if you are parked and can
orient the antenna you should be fine. If you want to use it while
driving, it is not going to work. There will be too much 'ghosting' of
the incoming digital signal and the tuners won't handle it well.

I am not certain there will ever be a market segment for what you are
searching.



It may be a few years before technology allows a cheap portable ATSC
TV, but it will happen. I think it's foolish to think people will
just stop wanting portable TVs because they're digital now. People
like their NTSC portable color TVs even though you can't get a very
good color picture most of the time and the screens are too small to
really enjoy it. It's certain that people won't want NTSC portables
after they stop NTSC broadcasting. Using a battery portable TV with
an AC powered receiver box makes about as much sense as using a
walkman with a rack component CD player.

Will not happen! Over the next few years the standard for
portable/mobile will be set by broadcasters like Qualcomm, Crown Castle
and others all of which will be using COFDM based modulations that will
be extremely robust.

Anyone trying to use a junk modulation like 8-VSB would be crazy and
whatever product they tried to sell would be laughed off the market.

This is what COFDM can do in a market like New York City. 8-VSB still
does not work in New York even for fixed receivers on rooftops with
fancy powered and rotored antennas let alone mobile with half inch
antennas like Qualcomm and Crown Castle will offer.

www.viacel.com/bob.wmv

Japan will start a mobile COFDM cell phone service in a few months. The
antenna is an inch at best.

HDTVs are actually a LOT cheaper than that now. You can get a 27ish
Sanyo set with a built in ATSC tuner for about $450 now. Not top
quality, but unless Sanyo is farming out manufacturing to Durabrand it
should be decent.

What is the 'correct' aspect ratio then?
Most people for the next 3 or 4 years are going to have 95% or more
stuff available over cable at 4:3 aspect ratio, why would they want to
buy a tv that would have those annoying bars on the sides for 95% of
what they are going to watch for a next few years?

Seems to me that it would be bass-ackwards to buy a tv set that does
not fit most of your available viewing material.

The problem so far in being able to get enough HDTV sets and ATSC
tuners available has been the widespread penetration of cable. To use
the still standard cable, you need a standard tv set. Cable companies
have been slow to provide HDTV capable signal at reasonable cost.

Sure don't have anything like that available at our PX or through AAFES
Online. Cheapest digital ready TV we have access to is $1000, 24" screen,
and has no digital tuner even available for it yet.

Not a widescreen, but not a bad deal for an entry level set.
No where near $1750-2100 either! Check your facts first.

I guess if it shows the correct resolution but why anyone would want to

If it's not widescreen, it's not HDTV.

Yes, it is HD. If you are watching an HD broadcast, there will be bars on the top and bottom. It cuts down the size of the viewable screen, but it is HD.
The effective screen size would be 29.4" instead of the actual size of 32".

True, and this is likely a piece of junk tv, but the poster I was responding to said that you couldn't get even an HD monitor for less than $1750.

I believe the sets he's referring to are called EDTV, they support 480p
which is an improvement over the 480i of NTSC, but nowhere near as nice
as 720p on a HD set.

How nice you can go to Wal-Mart. I can choose from either the BX/PX or
hundreds of stores on the local economy. The BX/PX are by far the cheaper,
and no such sets exist in their local inventory, nor on their website.
