A 1080p set has higher native resolution and supplied with 1080i (e.g., from some cable or satellite programs) or 1080p signal (e.g., from Blue-Ray discs) will provide sharper picture, especially visible on bigger sets (42-inch or more) and from up-close. 1080p sets are however way more expensive than 1080i ones. All flat panel HDTVs (i.e., plasma and LCD), as opposed to CRT tube sets, are inherently progressive in nature. For marketing reasons, however, some manufacturers promote 720p (p for progressive) HDTV as 1080i (i for interlaced), mainly to signal, I suppose, that it supports 1080i signal and to improve their sales. The so called '1080i HDTVs' take a 1080i signal and downconvert the picture to the 720p resolution. Additionally, they de-interlace the 1080i signal and display it in progressive scan mode but in 720p resolution. So, a 1080i TV set is in reality a 720p set, but many manufactures designated 720p sets as such as soon as 1080p sets came along. 1080p sets, on the other hand, take 1080i cable or satellite signal and only deinterlace it, creating a progressive scan, meaning the picture is painted from the top to the bottom line (there are 1080 such horizontal lines) in a single pass and this process happens 60 times per second (in the US). This means that same size HDTV sets designated as 720p and 1080i have identical native resolution of the display. Quality of the picture depends only in part from resolution, however, and according to some professionals the most important aspect of picture quality is contrast ratio, the second most important is color saturation, the third is color accuracy, and only the fourth is resolution.

720p, 1080i, and 1080p are three types of broadcast signals that may reach your HDTV set as an input, with 1080p being the highest quality and, as of mid 2008, only available on Blue-Ray discs and in high-end computer games. People often confuse these broadcast signals with native resolution of the TV sets. All flat panel HDTVs (i.e., plasma and LCD), as opposed to CRT tube sets, are inherently progressive in nature. For marketing reasons, however, some manufacturers promote 720p (p for progressive) HDTV as 1080i (i for interlaced), mainly to signal, I suppose, that it supports 1080i signal and to improve their sales. The so called '1080i HDTVs' take a 1080i signal and downconvert the picture to the 720p resolution. Additionally, they de-interlace the 1080i signal and display it in progressive scan mode but in 720p resolution. So, a 1080i TV set is in reality a 720p set, but many manufactures designated 720p sets as such as soon as 1080p sets came along. 1080p sets, on the other hand, take 1080i cable or satellite signal and only deinterlace it, creating a progressive scan, meaning the picture is painted from the top to the bottom line (there are 1080 such horizontal lines) in a single pass and this process happens 60 times per second (in the US). Finally, According to a CNET reviewer, see the link below, the extra sharpness afforded by the 1080p as compared to 720p televisions is not noticeable when watching 1080i sources on 50-inch or smaller sets from the distance of at least 8 feet. Last but not least, according to the Imaging Science Foundation, the most important aspect of picture quality is contrast ratio, the second most important is color saturation, the third is color accuracy, and only the fourth is resolution, despite being easily the most-talked-about.

They are both the same resolution of 1920 x 1080 pixels. The "i" and "p" refer to "interlaced" and "progressive".

An interlaced signal generates a full picture in two passes of the screen. The first pass, or field, is made up of all the odd numbered lines: 1, 3, 5, ... 1079. The next field adds all the even numbered lines from 2 to 1080. Although the field rate is 50 or 60 fields every second, the full image is refreshed 25 or 30 times each second.

A progressive signal generates the full image in a single field drawing consecutive lines 1,2,3 ... 1079,1080. So, a field rate of 50 or 60 fields per second also means a frame rate of 50 or 60 frames each second.

The difference between them is that fast movement tends to be handled better with a progressive scan compared to interlaced. It also uses twice the data rate as it draws double the number of lines in any given period compared to interlaced.

Currently, broadcast signals are almost exclusively 1080i with 1080p limited to local sources such as HD games consoles and Bluray.

The field rates of 50Hz or 60Hz vary depending on the region. Europe and some other parts of the world use 50Hz while North America, Japan and some other regions use 60Hz. The difference is the result of many years of history and there is no sign of the two frame rates being merged into one rate in the near future.

Do 1080p TV sets convert 1080i signal to 1080p format?

All LCD displays use progressive scanning, namely the whole frame is built up line by line rather than odd lines followed by even lines. Therefore, by default, 1080i will be converted to 1080p, but at a frame rate of 25Hz or 29.97Hz. 1080p sets take 1080i cable or satellite signal and convert (deinterlace) it, creating a progressive scan, meaning the picture is painted from the top to the bottom line (there are 1080 such horizontal lines) in a single pass, and this process (in the US) happens 60 times per second. 1080p is normally run at 50Hz (Europe) or 59.94Hz (North America). 1080i is normally half that frequency. Even if the signal is converted from 1080i to 1080p, there is no additional picture information and therefore, little is gained by the conversion. If the television actually does the conversion, it is worth doing a comparison between converted and unconverted to see which produces the most pleasing results.


Will a 1080p home theater system work with my Panasonic 1080i CRT HDTV?

1080 is a video standard and has nothing to do with the audio. Connect the stereo audio outputs of the tv to the inputs of the home theater. Check the HT menu to be sure it is set for multi channel audio on the input you are using.


How do you convert a TV into a 1080p TV?

1080p and 1080i both refer to the format of a video signal. Any HD television will receive the signal and display it. If the television reports the signal standard being received, it will let you know what the signal is. Therefore, the television cannot be changed from one standard to another as it simply handles the incoming signal. Currently, broadcast HD signals are almost exclusively 1080i with a few formatted as 720p. Both are considered full HD even though the resolutions are different. 1080p is found on some local sources such as games consoles and Bluray players but has not yet made it to mainstream broadcast services.

What kind of formats are available for HDTV televisions?

There are three types of HD formats-720p, 1080i, and 1080p. Progressive and Interlaced Scanning are also available for an HDTV to use.


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.


What are the compatibilities of a Blu-ray disc playing on a Blu-ray player set to play in 1080i on a 1080i HDTV?

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.


Are there HDTV's that can switch between 1080p and 1080i?

If the TV is 1080p capable, it will switch automatically when it receives a 1080p signal. Keep in mind that not all cable and satellite systems will have this service. Look for the INFO button on the remote to see what standard you are receiving.


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)


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.


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

Is a 1080i TV compatible with 1080p cable?

Most modern LCD/Plasma TV's are capable of receiving and displaying 720i, 720p, 1080i and 1080p signals. Therefore your TV, if it can receive 1080i, should be quite happy with a 1080p signal.


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

What is the difference between 1080p and 1080i HDTV?

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.)
