1080i?

I have heard of hd resolutions of 720, 1080p and now my lcd info shows
1080i. This is confusing...reminds one of ordering a coke.."do u want
a small drink, medium, large or jumbo...is this what HD is coming to?
another gimmick?

1080i is the interlaced flavor of 1080
Odd lines are scanned, then even every 1/60 second for a "new" picture every
1/30th.
The knowledgeables in this NG suggest that nobody is transmitting in 1080P
(unlike Blu-Ray) and it is your set that eventually converts the signal to
1080p

In the USA, 720p is used by ABC, Fox Broadcasting Company and ESPN because
the smoother image is desirable for fast-action sports telecasts, whereas
1080i is used by CBS, NBC, HBO, Showtime and Discovery HD due to the crisper
picture particularly in non-moving shots.

As mentioned you can get 1080P on blue-ray DVD but it is not used for
broadcast TV in the US.

And how strong are the claims that you can tell the differerence
between 1080i and 1080p? Is more likely on a 70" or greater sized
display?

What about the UK?
Does anyone know if the UK transmits in 1080p?

I have only one piece of data on that. A few months ago there was a
Blu-ray display at Sam's. One half of the screen was "supposed" to be
Blu-ray 1080p and the other half "not", supposedly either 720p or
1080i, I'm not sure which. There was definitely a difference, with the
Blu-ray far superior, very easy to see. Of course, the purpose of the
display was to get people to buy the Blu-ray player.

FWIW...

Depends on the source material. Good quality transfer of a 35mm film
at 1080/24p, yes, it will look better. Not so good transfer with a ton
of edge enhancement? 1080/24p may not look much better. But a properly
encoded 1080/60i broadcast of a 1080/24p film source with a TV or STB
that recognizes 3:2 pulldown and generates a 1080p image can also look
very good - if it all works.

Nit point: 1080p is rather vague. There are different framerates used:
24p for movies and TV shows shot on film or the budget TV shows & movies
on 24p HD video, 25p used in the UK and Europe for TV productions, 60p
which is not really available at a consumer level.

1080i could be 1080/50i (UK & Europe PAL HD format) or 1080/60i (US).

Actually, this is old. 2-3 years ago you saw a lot of sets advertised
w/ 1080i, & many of them got good reviews. But for some reason they
disappeared almost entirely.

I can tell you that I could not see the difference between 480i and 480p
on a 32" HDTV. Maybe my old eyes are not quick enough...lol
