1080i/1080p

my 1080p TV isnt up to its potential yet with my cable. Cable only has 1080i right now, next month it will have 1080p (:D).

Something that always puzzled me...is what the hell is defferent between Progressive scan and...."i"...(cant figure out what it stands for right now.)

I know it has something to do with the updating of the pixels, like "i" updates only with vertical, while "p" updates its pixels through both vertical and horizontal. Thats pretty much all i know, besides the fact that "p" has better quality of picture than "i". But ive watched baseball games, hockey games, and TV shows in 1080i for sometime now, and i think to myself..."how can it get any better?!"......

the "i" stands for interlaced...

1080i vs. 1080p (Googled it)

"how can it get any better?!"

look outside :)

#453236

haha, even outside looks dull compared to the TV :P

EDIT: my LCD upgrades the 1080i signal to 1080p.....:confused:

#453237

Really?

And just how does it do that?

1080i transmits the signal where it draws all even numbered horizontal lines first and then the odd lines.

1080p draws them in sequence giving a smoother appearance.

So for your TV to do that, it would have to cache a 1080i HD signal, reformat it and then display it.

Someone is pulling your leg my friend.

And just an FYI... the HD signal you get from Cable and Satellite TV is only 1080i formatted. It's not a true HD signal. The bandwidth requirements to send full HD signals over cable or to 18" dishes is to high for them to be fully utilized. They can still advertise as HD because the format is still HD. The quality of that signal is something else.

There's a reason why an HD antenna is 6 feet wide. It's a big signal with a ton of information in it.

Check out an over the air HD broadcast and compare it to one from your cable or satellite provider. There is a noticeable difference in clarity.

Oh... and nice choice Tim!

read the article. thats what it says :P

Close but no cigar.

You are still viewing a 1080i quality broadcast as you are only receiving 30fps and not 60fps.

So to say it converts to 1080p is misleading. The amount of data received is still less, which means lower signal quality.

Unless the picture is horribly distorted, that TV is not a widescreen... there's no such thing as a Samsung 4:3 40" LCD. Also the camera on a MBP should be much better than that.

I am in the market for a 24" monitor and I see them advertised as being able to produce 1080 quality (1920*1200). but is it the p or i that an LCD produces .

#453300

they took this picture before they shipped my tv..

i went to see the 103" Panasonic tv @ john lewis in oxford street (if you don't know where that is, you are uncultured :P)

it didn't seem that big, although i understand what hd means now.

the thing is, when people (me atleast) see large tv's they automatically expect hd, while it may not really matter for the jumboscreen outdoors, i always assumed if i ever got close enough it would be high quality.

#453320

I got my TV for half off 'cause the stand doesn't come off. But I wouldn't risk wall-hanging anyway, so it's perfect as far as I'm concerned. Plus, I like playing with the power swivel during commercials. *smug look*

Also, I know bigger is not better. As you would expect, regular cable looks like absolute s**t, and DVD's don't look much better.

So until I get my PS3 for Blu-Ray, I'm stuck watching the news, American Idol, and Planet Earth (;)

EDIT: Timan, yours isn't bad either... mwahahahaha...

and rjohnstone... I don't see much difference...

1080i or 1080p is determined by the signal being sent, not how the monitor displays it.

Most HD TV stations still broadcast in 1080i. Meaning they are only send 30fps at 1900x1080.

Did a bit more research on it last night as I'm in the market for a new TV.

LCD and Plasma do "convert" to a progressive scan (p) display, but they do it by using a line doubler. It's in fact not true 1080p quality.

The difference between i and p is most noticeable in action scenes or scenes with a lot of movement, sports for example.

(i) will be more jagged on the edges where as (p) will be very fluid or smooth and give a more realistic display.

Speaking of Discovery HD, anyone else watch Planet Earth in HD? Orgasmic quality.

#453492

I watched it, Timan. GREAT work by BBC and terrific quality. :)

Yeah, it was awesome, shame you can't buy it in that quality... (yet?)

the sad thing is that here in sd, we only get a handful of hd channel. discovery in hd is probably the most impressive channel so far.

#453576

Well, the local news in HD is the one I show off to visitors. This way, they know how to compare. It feels so weird to watch an SD channel forever, and then "discover" HD

I'm looking to purchase the 26" Samsung TV i think its 720p i'm not too sure at the moment though... Does anyone have any recommendations on any other TV's about the same price?
