1080i and 1080p are both High Definition display formats for HDTVs. 1080i and 1080p signals actually contain the same information. Both 1080i and 1080p represent a 1920x1080 pixel resolution (1,920 pixels across the screen by 1,080 pixels down the screen). The difference between 1080i and 1080p is in the way the signal is sent from a source component or displayed on an HDTV screen.

In 1080i each frame of video is sent or displayed in alternative fields. The fields in 1080i are composed of 540 rows of pixels or lines of pixels running from the top to the bottom of the screen, with the odd fields displayed first and the even fields displayed second. Together, both fields create a full frame, made up of all 1,080 pixel rows or lines, every 30th of a second.

In 1080p, each frame of video is sent or displayed progressively. This means that both the odd and even fields (all 1,080 pixel rows or pixel lines) that make up the full frame are displayed together. This results in a smoother looking image, with less motion artifacts and jagged edges.

1080p can also be displayed (Depending on the video processing used) as a 1080p/60 (Most common), 1080p/30, or in 1080p/24 formats.

1080p/60 is essentially the same frame repeated twice every 30th of a second. (Enhanced video frame rate.)

1080p/30 is the same frame displayed once every 30th of a second. (Standard live or recorded video frame rate.)

1080p/24 is the same frame displayed every 24th of a second (Standard motion picture film frame rate.)

The terms 1080i (interlaced) and 1080p (progressive) indicate how images are stored and displayed. In the days of analog tv this would be important, however with the advancement of technology most digital tvs can handle both 1080i and 1080p signals.

The main difference between a 1080p and a 1080i HDTV is the method used to decode the digital signal being sent to the television. 1080p signals send each line to be displayed on the television in a progressive manner. 1080i signals send every other line of the display, also known as interlaced. A 1080p television should be slightly faster as rendering the image since it does not have to interpret the pictures being sent, as they are all in the correct order, but this means the 1080p televisions are probably more expensive,

What is the difference between hdtv and 1080p hdtv?

HDTV is the term for a range of television formats. The common formats in use today are 720p, 1080i and 1080p. There are other resolutions that can also be classed as HD but are not in use today. Each of the resolutions can be delivered at a variety of frame rates. 1080p is just one format in the HDTV class. It uses 1920 x 1080 pixels and the image is created by a single pass of the screen from the top to the bottom of the image. Contrast this with 1080i which requires two passes of the screen from top to bottom to create a full and complete image. 720p and 1080i are the two formats used for broadcast at present. 1080p is found in local sources such as games consoles and Bluray discs but not yet in live broadcasts. Any HDTV will handle any of the HD formats without any user set up required.

What is the difference between 720p and 1080p TV definitions?

HDTV can be a bit confusing since you can get different definitions. The difference between 780p and 1080p is the number of pixels, which are little dots that make up an image.

yes but can you play 1080 i through component on newer discs? supposedly im reading with the upconverters and newer discs you cant to prevent pirating its only possible on dvi and hdmi. The compatibilities are that blu ray disc basically will play in a blu ray player in 1080i on a 1080i hdtv !, I figured out today that, that is the answer to this question because I own a blu ray player set to play 1080i blu ray discs and I baught pirates of the Caribbean 1, 2 and 3 on blu ray today and saw all of them and they all work on a 1080i hdtv with a blu ray player set to play in 1080i instead of 1080p because I don't have the newer version of the sony bravia hdtv which is the 1080p, what I have is a sony bravia 1080i hdtv!. I hope this answer helps other people out who where in my same situation! with hdtv and blu ray player hooked up together.


Does playstation play Blu-ray in 1080i?

No that feature is for the PS3 and it is in 1080p resolution if your playing the movie on a 1080p hdtv, with an HDMI chord (I don't know if component cables play in 1080 or just 720)


How do i know if my HDMI cable that's hooked up to my 1080i hdtv is 1080p?

The TV decides whether it is a "i" or a "p". The cable will pass both types of signals.


Why is your 1080p television showing 1080i?

It's to do with the resolution. The 1080 identifies the number of lines that create the image, so 1080p and 1080i have the same number of lines. The letter stands for the type scan the TV uses. The P stands for progressive and the I stands for interlaced. Progressive will process the image twice as fast as interlaced and therefore produces better colour and clarity.


Is it worth buying a cheap 1080i HDTV for playing playstation 3 games?

It's worth buying a high quality LED LCD 1080 P HDTV. I personalty don't see the value of buying a 1080i HDTV and feel that since HDTVs will last for years the LED LCD HDTV in 1080P is the best choice in spite of the higher cost. It may become worth buying a HDTV 3D, but currently they do not have enough 3D material and prices will drop
