1080i / 1080p

[Awesome Conquerer]

Hi, Awesome Conquerer here...lucky you !
In laymans terms, visually speaking could someone describe what my eyes would be missing watching blu ray in 1080i vs 1080p?
Thank you,

Search button is your friend. There are multiple threads out there dealing with this, and one is even in the stickies at the top of this forum.

You need to be more descriptive. Are you asking about the difference between watching BD on a 1080i (768p) display versus a 1080p display? If so, at what viewing distance and what display size? Or are you asking about outputing your BD in 1080i versus 1080p?

Uh oh...technical questions
My Panasonic plasma is 1080i. Ive just added a blu ray player and while I sense subtle differences in the display and noticeables differences in the audio output Im not bowled over with the results.
My question is more general in nature. are there dramatic differences between 1080i and 1080p?
I will seek out the other threads. Sorry for being redundant.

A lot depends on

1) Your eyesight
2) Size of your television
3) How far away you sit from it
4) Movie you're watching
5) Settings/Calibration of your set


You're connected via component or HDMI to get the actual 1080i resolution correct?


What speakers/AVR is that in your photos?

blu ray HDMI to reciever HDMI to tv

B&W speakers

wear corrective lenses
37"
10" away from set
just discovered set needs to be callibrated...dvd's on market ok?

For that size set, you're sitting about 3 feet further away than optimal viewing distance.

What does "DVDs on market" mean??? I'm just saying some Blu-rays look better than others. If your AVR decodes the lossless audio, or accepts it from the the PS3, that's another great bonus....

Anyways.... I think you're sitting pretty far from a 37" set.... I sit 8' or so from my 37" 1080i set, which is still really far, but I don't use it for Blu-ray.... The two I have Blu-ray for currently are my movie-room, and bedroom.

I sit 9' or so from my 106"
and use a 32" in the bedroom which is way too far away too, but I still notice a difference......

I would get DVE basics, and calibrate that way..... I didn't spring for a professional calibration either, but like the results I got with the disc.


EDIT:

Bhampton

because many 720p displays accept and display 1080i images

[bhampton]

I can't figure out how they can take 720p displays and call them 1080i.

They have approx nothing to do with 1080i. Makes no sense to me.

Either way... 1080p will be standard for a long time and you will find nothing but "deals" while they try to hand off remaining 720p sets.

Ill give it a try. Thanks.

I can't see how they call a 768p display 720p!

Okay, so you have a 768p 37" Pany plasma and you are sitting 10' away. Got it.

I can tell you that I have 2 (42" and 58") 768p Pany plasmas, and the difference between DVD and BD is like night and day. You should be able to tell a BIG difference, especially if you get closer to your display. Tweaking your settings with DVE or Avia won't hurt, but I really can't see that causing you to not see a big difference between DVD and BD quality.

Have you checked to make sure your BD player is outputing a 1080p signal (assume your set will accept a 1080p signal)? Even if it is outputing a 720p/1080i signal, it should still look noticeably better than a 480i/p DVD.

Don't let folks try to convince you that your problem is that you don't have a 1080p set. That's complete BS. On larger displays and/or closer viewing, there will be noticeable difference going from a comparably-sized 768p set to a 1080p set, but nowhere near the improvement you will see going from DVD to BD on a 768p set.

Me thinks his query was inregards to a BD player vs HD STB.

Cool handle.

That might be... Why the heck did I think he was discussing differences between DVD and BD?

[bhampton]

Quote "because many 720p displays accept and display 1080i images "

Well,... I don't think so.

720p displays accept then convert 1080i images into 720p images.

They can not display interlaced video at all. CRT can. Fixed panel devices can not display interlaced video without first de-interlacing it and converting it to match their native resolution.

-Brian

[dobyblue]

Hitachi made some plasma's which could display interlaced images...but I think what we all agree on is that manufacturers should put the panel resolution as the advertised resolution, not what signals it can handshake with.

Truly people are confused about this.

Yes, indeed there is a dramatic difference between 1080i and 1080p based on the content. If you are watching a talking-head there is no difference between these two since no motion is involved. However, when there is high motion, e.g. sports, action and dancing 1080p is much better than 1080i since 1080i could lose resolution up to 50% based on the amount of motion in the original picture. Above description is entirely true for 1080i vs 1080p where original content was recorded in those formats.

However, if the original content is 1080/24p, theoretically this can be transmitted over 1080/60i link and 1080/24p picture can be reconstructed without losing information. That is theoretical but in practice that may not be the case depending on the implementation of the deinterlacing process of the display.

Sorry the answer is not simple.

[dobyblue]

If you want to understand a bit better what syncguy is talking about regarding actual FILMED resolution, then read through this entire article. The illustrations are particularly good and make it a lot easier to understand the difference between filmed resolution (source) and the resolution you're broadcasting at.

It also helps explain why 1080p24 can theoretically become 1080i60 and get back to 1080p24 with no loss.
