1080i,1080p.What's the difference?

Can anyone answer?

one is of higher quality than the other? ... 1080i is more detailed than p i think .... weiliang_1988

Progressive scan is 60 frames a second while Interlaced is 60 fields a second, or 30 frames a second. A full frame is all vertical lines of resolution, in this case 1080 lines. An interlaced field is half that many, 540, filling every other line. The second pass fills the other 540 lines, generating a full frame every 1/30th of a second. On older CRT televisions the first set of lines begins to fade from the phosphor as the second set is drawn resulting in possible flicker. On newer digital sets, which are always progressive, a blending of fields occurs.

Ultimately the easiest way to explain the difference is twice as much information is seen every second with Progressive scan resulting in smoother video.

Since this is the PS3 board there could be a variety of reasons you are asking. On the PS3 you mark all of the resolutions your display supports and the PS3 switches to the appropriate mode. If you have a 720P/1080i display, when you are at the XMB you are looking at 1080i. If you play Resistance the display is adjusted to 720P. If you watch a Blu-ray movie or play a 1080P game you see a 1080i image. For Blu-ray this isn't too much of an issue as most Blu-ray media is 24fps, less than either 30fps Interlaced or 60fps Progressive.

No its not. 1080p is the best one with the highest quality. Basically it goes like this, "p" means that all the 1080 resolution is shown all at once on the screen, while "i" is when only half of it is shown at once and it switches back and forth very fast producing a 1080 looking picture. "P" will always be better than "i" no matter what because the response rate is much higher so the image will move more smoothly. Even 720p is better than 1080i in allot of cases especially in video games because 1080i may produce a little bit more detailed image, but 720p will perform better in most instances.

For your information:

Roger N. Clark estimates human vision resolution to be equivalent to 576 megapixels (24000 x 24000 pixels) for a 120 degree field of view. Extensive background, assumptions, and calculations are available at http://www.clarkvision.com/imagedetail/eye-resolution.htm

the 1080p has 2million pixels while the 1080i has one million.The differnce is very big because the pixels are the quality of the picturejimmysCY

Thanks for the info.The reason i wanted to know is because I just got me a Sony Bravia and it has 1080p stamped on it whereas my friend has 1080i on his Phllips tv.We just wanted to know the difference.I own a ps3 by the way.
