What is 1080i and 1080p?

What is 1080i and 1080p?

Full name of “p” in 1080p Progressive scan and full name of 1080i “i” is interlaced. HDTV, also known as High Definition Television, is actually a good variation from old and standard analog TVs. However, when it comes to choosing a certain unit, people are still upset and they find it hard to choose one. The biggest question that comes out is, what is the difference between 1080p and I HDTV? Actually, there are two types of HD broadcasting. These are 720p and 1080i that use a resolution of 1280 x 720 or a picture above 1280 pixels and up to 720 pixels high. P in 720p really stands for progressive scan. This only means that the photo is refreshed or reproduced for up to 60 times per second, down from top to bottom and in a single pass.

1080p vs 1080i

The HDTV set and video coding are based on the number of numeric values ​​assigned to the rows that are capable of displaying, thus 720p has 720 rows and 1080p / I are 1080 lines. The difference between P and I is the method in which the picture displays Are being done. P stands for progressive; This is a method where the entire image frame is displayed at a time.

I stand for Interlaces which is a bit more complicated In the intersection, an image is cut in 1080 pixels pixels, all weird numbered strips make an image, whereas all numbered strips are considered as second, with an image frame Is broken into two images, which are played in quick succession to fool the eye. Just put, 1080p is better than 1080i because it does not use tricks to display a 1080 resolution. Due to the filtering methods applied to the signal, 1080i has an effective solution of only 800.


  1. 1080p images are progressively displayed whereas 1080i images are interlaced.
  2. 1080p has an effective solution of 1080, while 1080i is only due to 800 filtering.
  3. The 1080p set can accept 1080i signals for display and deinterlace.
  4. 1080i sets that accept 1080i signals need to process signals to display it.
  5. Most media today come in 1080i or 720p and are only for very low 1080p.


These prices do not apply only to TV sets and other display devices, video signals can also be in 1080p or 1080i A 1080i video signal can be played in both types but the display device can be shown before it can be shown to the 1080i signal Deinterre. While playing a 1080p signal, in a 1080i device it can be a little tricky. Some devices can not play 1080p video; You can not do anything about it to others, but it will need to reduce the 1080p signal so that it can be displayed at all, which means quality damage.

The disadvantage with 1080p is that at this resolution only play a very limited amount of media; Most are using 1080i or 720p This means that even if you have a 1080p capable player and a TV set, if the disc you are playing is only in 1080i or 720p, then there is no use for it. The only console is that 1080p There is a final future. Most manufacturers and media makers will take the same time before going to 1080p format.


This is a shortcut for the progressive scan along with 1, 080 lines of vertical resolution for the set of HDTV video mode, which means the image is not the only 1080i standard display like interlaced word actually is about 16: 9 widescreen aspect Acquires the ratio and it means horizontal resolution of 1920 pixels. This resolution is similar to 2K digital cinema technology. Frame rate can be specified by reference or after a letter specified in the letter P like 1080p30 it only means that there is 30 progressive frames for each other, no one is broadcast in 1080p and no sooner than Not expected. However, there are digital formats that can produce original 1080p signals. HD and Blu-ray DVD players are some great examples.


“i” means interlaced and it is a big difference in 1080p, in which the P stands for progressive scan. The word 1080i actually considers the widescreen aspect ratios of approximately 16: 9 and about 1920 pixels of 1920 if the frame size means.
The area of ​​”I” is generally 60 Hz for those countries which use System M as an analog broadcast television system such as Canada, America, Brazil and Japan. Both types of digital digital broadcast transmission formats like DVB and ATSC are the same.

What is the difference between 1080p and 1080i?

The difference between 1080p and 1080i can offer that there are some features. Those aspects which may vary from one to another may be the opposite of 1080p which can show the clear mode for video 1080p. It can only display 1080p Blu-ray and HD DVDs in its original and full resolution formats. There are different models with different support modes on the other side, 1080i is a video or broadcast mode.

Using the character “P” and “I” shows the scanning technique and “1080” indicates the resolution.

“P” is for progressive scanning and “I” interlace scanning.

1080p means that there are 1080 lines of vertical resolution in the display and scanning is a progressive scan. The full resolution of the display is 1920 × 1080 pixels

1080i means scanning interlaces and aspect ratio is 16: 9, so the full resolution is 1920 x 1080; 1920 pixels horizontally and 1080 pixels vertically.

When it is marked as 1080p30, resolution of 1920 × 1080 with progressive scanning and frame rate is 30.

Interlaced scanning is an old technique, while progressive scanning is now used most often
