720P, 1080p

Someone told me that most high definition channels out there and those that
will be broadcast in HD will in in 720p format. The only benefit to get a
1080p is for HD DVD like blue ray. Is this true?

Absolutely not. The electronics should be newer/faster and do a
better job of rendering 720p and 1080i, too.

If you'd said "maybe not" and "might ... do a better job", I'd agree
with you :-)

Well "new" 720P sets will be newer/faster also. No advantage for a
1080P set there.

No broadcast in 1080P. No content OTA, maybe cable or satellite will
offer it but not in the near future IMO.

Anything 50" or smaller will not show much difference unless you are
into counting pixels instead of watching TV. If you sit close enough to
see pixels your are too close in my book. And if you can't see pixels I
don't think you will see much difference between 1080i, 720P or 1080P on
anything 50" or smaller.

Most HD broadcast and cable channels are in 1080i format or more
specifically 1080/60i (60i = 60 frames per second interleaved).

The current networks that are 720/60p a
Broadcast: ABC, Fox, My Network
Cable: ESPN-HD, ESPN2-HD, National Geographic (because it is part of
the Fox system). It is expected that ESPN News-HD and probably FX-HD (&
other Fox channels) will be 720p when they start up.

Everybody else is 1080/60i:
Broadcast: CBS, NBC, CW, PBS (although there are a few PBS stations
that broadcast 720p for their HD sub-channel)
Cable: HDNet, HDNet Movies, TNT-HD, Discovery HD, Universal HD,
HBO-HD, Showtime-HD, Food-HD, Lifetime Movie Network HD, and the rest.

A 1080p display can de-interleaved film source material for a 1080i
source, if the TV electronics & firmware are done right. But at 50" and
under, the difference between a 1080p display and a 768p display (common
resolution for many LCDs and Plasmas) are very difficult to see at
typical living rooms sitting distances. Unless you are getting a large
screen, 1080p is not that critical to selecting the TV. At 50", 1080p
may be nice to have, but real world contrast (not the silly contrast
numbers they list for the TVs), minimum black levels, color accuracy,
viewing angle are all arguably more important.

Do not get too hung up on 1080p which has become a buzzword that the
industry is using to push people to buy more expensive models. In a few
years, I expect all the flat panel TVs 40" and bigger will have 1080p
resolution screens, but at the moment, it commands a premium price. You
have to decide if the premium is worth it for the amount of $ you have
to spend.

No. (To both claims.)

Bigger and better, room for expansion, and though 1080p is new - just
a matter of time for bandwidth to catch up to a standard. Best hurry
while limited supplies last ... etc, etc. Meanwhile, buy a Sony
Gameboy 3 or somesuch for $300 and Sony might toss in half a dozen
movies at 1080p Blueray. (Rather have updated AMD/ATI drivers for
native 1368x768 from a couple dated AGPs and forgo the update game
thingy awhile, thanks all the same).

Bzzzt. False.

A 1080p60 display will be able to give you the full resolution of a 1080i30
program, as well as give you the full frame rate and frame consistency of
a 720p60 or 480p60 program. But beware of shady manufacturers that will
market a set as "1080p" which in fact it is "1080p30". I don't know if any
set has that issue yet, but I would not be surprised if one or more do.
So be sure you check not only the resultion but also the frame rate of any
TV, monitor, display, or projector you might buy.

There is the possibility that future cable or satellite program providers
could send programming that is actually shot and produced in true 1080p60
format. Equipment to do that exists, but is expensive and has to deal with
the fact that most TV producers have already drained budgets to buy other
HD production capability. But a single QAM256 channel on cable could do
such a format. A satellite transponder could probably carry 3-4 of them.
They would probably require using a special box provided, and the channel
would almost certainly be a premium sports channel (the 60 fps frame rate
is a big plus for sports, but doesn't gain anything for movies, which can
do 1080p24 right now).

Blu-Ray is more likely able to do 1080p60 than HD-DVD because BR has 66%
more disk surface capacity. But unless you are going to be watching sports
that is recorded and old, what good will 1080p60 do for you? Movies will
be in 1080p24 if they do it right. Maybe some educational videos will be
able to benefit from 1080p60. The major benefit of 1080p60 capability is
more for being able to display either 1080i30 or 720p60 with best quality.

Typo. That's 60 _fields_ (half frames) per second.
