HDTV question: 1080p content on 1080i ..Wont Work?

Hi,

I have a question...

If i connect PS3 or play Blue-ray movie disc All of which have 1080p output on a 1080i HDTV which is 1920X1080 interlaced....... Will the video on the screen be interlaced or progressive? ...will it be de-interlaced?


in short... can a 1080i HDTV ever give out de-interlaced content if the source is Full HD???

 

a "1080i only" tv will only display interlaced images at 1080

many wont even accept 1080p as an input, but if they do it will interlace it down to 1080i. I have a 65" tv that does this.

It is possible the tv supports 720p, which will look nice also... but 1080i is better than 720p (arguable... i kno)

What is the model and technology(CRT, LCOS, DLP, LCD?) of the TV?

 

If the HDTV CRT and the input is 1080i, then it will most likely be shown interlaced. On the other hand, if it's lcd/plasma/etc the display's circuitry will deinterlace it. I never heard of an interlaced lcd lawl ;D

 

It would be 1080i.

Also, you might have to go in the players/ps3 options and change the default resolution to 1080i. When displaying 1080p, if the TV doesn't support 1080p, it dowscales to 720p, then 480i. 720p is not supported on many CRT HDTVs.

Only HDTV broadcasters seem to know about 1080i...

 

Almost everything supports 1080i as an optional output, 1080P is the more rare/recent option. PS3 supports 1080i and 1080p

What type of HDTV is it? As mentioned it won't display a 720P image if it's a 1080i CRT like one of the ones I have.

It might say 1080i support on some LCDs, but really they are dropping lines and downgrading to 720P (edit: for those that don't support 1080P), and others use other interpretive reoslutions, usually through dithering, where you may have 1280x1080 or 1440x1080, etc. displaying as something else.

If your TV is native 1080i its likely a CRT, and then it's also likely to be 480/540P set, with only those two option (1080i and the single Progressive) as non-converted inputs.

What's the TV?

But if your source is the PS3, no worries, it supports 1080i;
http://www.us.playstation.com/ps3/about/specs
So it will show the 1080P content in 1080i format, maybe doing some converting on the way from 24P to 30 frames / 60 fields interlaced.

This LCD TV is 720p ... the Samsung Bordeaux LA40R81BX IS NOT HD Capable.. Bravia is HD capable..
So what will happen when 1080p or 1080i Signal is given to non- HD capable Samsung?.. will it go blank?

 

To be future proof i heard 720p (HD capable) is better.. as 1080i wont be future proof if all movies & games start coming on 1080p ...
1080i is not good for Gaming or Sports or Action Movies as the interlaced pattern causes blur in motion.

 

Gonna clear up some things.
The last post is somewhat correct. Games are soon to be announced in P mode. but for now, all computer graphics is mostly Interlaced.
Which mean in your case its a choice of 720p or 1080i i would go with 1080i. Playing movies though, is p.
televisions that can do 720p can also do 1080i, but never ever 1080p.
Hope this helps.

 

Your native resolution is 720p. Set your ps3 to output 720p and you will see the best picture

With regards to the samsung that isnt HD capable. i dont understand how youd be sending it an HD signal? if its not HD capable then it wont have HDMI or component (unless its ED) inputs. And unless youre using an HDMI or component cable as your medium, you have no chance of transmitting HD?

 

No it's not. Most computer graphics is progressive.

Actually since he provides the specs above your post, no, his best option would be 720P since that's the native reoslution of his panel (or the computer equivalent).

There's no advantage to outputing it interlaced at a higher resolution and then having the TV 3:2:2 pulldown is just doing extra conversion steps, no point, just let the PS3 downscale from 1080P to 720P, much better.

 

I will correct myself, when proven wrong.
It's true that today its mostly progressive. Thats the advantage of lcd. CRT uses interlaced.
using 1080I instead of 720P will give me a better spatial resolution. Not much, but it is increased, and that would be the benefit of using it.

 

No it doesn't.
TV uses interlaced, computer CRT are progressive, I'm wroking on a P260 beauty right now.

1080i would still be displayed at 720P, so once again 2 very complex p-i i-p conervsions to do what the PS3 would do better down converting from 24 fps 1080p to 24 fps 720P. Not sure how the spatial resolution is going to be improved along the way.

 

The Samsung model i mentioned is 720p but its not 1080p capable... Sony Bravia V40 is capable.

Does it mean Samsung wont process 1080p input via PS3 or Blue-ray??

 

Not true. Computer CRT is mostly interlaced. look it up.

The improvement in spatial resolution comes as interlaced requires less than half the bandwith. Not that it's digital is no longer half, but there is still a small procentage to be won, by doing it interlaced.
And you can look it up.

 

Computer monitors haven't been interlaced since the early 90s, and I remember the issue because I worked in TV in Montreal at the time.

I work on the best of them everyday like the P260 I mentioned and the very best IMO the W900 24" Sony we have in the geomatics lab, I am familiar with their features/limits.

While I usually deride Wiki, at least this gives you a starting point;
http://en.wikipedia.org/wiki/Progressive_scan
"Progressive scan (also known as: P-Scan) is used for most cathode ray tube (CRT) computer monitors, all LCD computer monitors, and most HDTVs as the display resolutions are progressive by nature. (Other CRT-type displays, such as SDTVs, typically display interlaced video only)"

What it the bandwidth limit you're talking about, in single-link TMDS, RAMDAC, HDMi, DB-15 connection, the cable, what exactly requires any bandwidth concerns?

Also I don't know how it would reduce the inevitable artifacts caused by re-interlacing and then de-interlacing an image?

Edit: anywhoo, glad to see you found the correct info.

 

It doesn't matter, the Sony PS3 wil; output 720P to the TV, as will pretty much any HD-DVD and BluRay player. You can usually either set the option manually or else it auto-detects you TV's support.

There is no benefit to outputing to a non-naitve resolution, the PS3 does a very good job of video processing, this article does a good job of showing how it's better than the standard, and even better than the programmable solutions from AMD and nVidia at the time (both AVIVO and PureVideo have been tweaked since, but you'll get the idea);
http://www.firingsquad.com/hardware/autumn_2007_video_shootout/page3.asp

Anywhoo doing 2 tougher conversions instead of 1 easy one makes little sense, especially since your TV can't actually display 1080i or 1080P (or even 720P without letterboxing technically), so whatever you chose is going to show up as 1366x768 (a standardized computer resolution) whether it's altered to fit it or you let it letter box it to the true 1280x720.

Really the only way to have better is either get content created for 720P (like Fox Sports) or else get a 1080P/i TV.

 

Why i have posted this article is because i am about to buy a 40 inch LCD HDTV..

I am stuck between Sony Bravia v40 & Samsung Bordeaux 40LBR 40..

Which is better for Watching Blue-ray movies, PS3, & computer screen use???

I have hyperlinked specs of both in previous post..


According to me Sony bravia is better but Samsung has been rated better on CNET Asia ..

btw i am an audiophile too...& heard Bravia has better technology called 'S-force surround'


So can u recommend me which is better & will future-proof me better?

 

Personally I prefer Samsung's LCDs as among the best there are, I like Plasmas better, but for LCD I like Samsung.

The features on the Sony beyond the panel itself are as usual great and a few I like such as PAP/PIP would pull me a bit.

My main question is whether or not the 1080P panels are an option or not?
The Singapore site for Samsung shows the LA40M81BDX, LA40N81BX and L40M81BX as 1080P options instead. Of course often they are more expensive.
Personally I would never buy a 720P panel at this stage.

As for the sounds, really if you're an audio file, turn of the TV speakers and use your surround sound, it' going ot be better than those 10-15 watt jobs tacked on the side, regardless of the audio processing they have, even if it could handle decoding DolbyTruHD or DTS-HD Master I wouldn't expect much out of them.

From your options, for picture quality I would say Samsung, for features Sony.

BTW, they both have the same native res, and both would handle any input, but just process it onboard.

 

Edit:

I just want to say, that i've found other discussion treads about the same subject. It seems that what i've been informed is incorrect. You were right, i was wrong.

 

I am buying Sony Bravia V series 40 inch + PS3 + COD4 (ps3)

Is that a good buy?

 

The V series that came up for me on Google says it does 1080p, so yeah, good choice. I wouldn't buy anything less at this point. Especially if you are going to watch Blu-Ray movies.

 

No worries, we can all be mislead by others.
Just making sure nocturnal gets the best he can out of the gear he has.

 

It's OK, but like I said I would prefer a true 1080P panel, that Bravia V series you linked to says (unlike what Raziel says) it's NOT 1080P but instead 1366x768 like you have listed above.

I would prefere one of the 3 Samsungs I listed above from their site which are true 1920x1080 resolution.

However it will still be a nice combo, so if you can't afford or have limited access to a 1080P LCD in Singapore, then that Sony is a good choice for a balance of features and picture quality.
