Difference Between 1080p and 1080i

1080p vs 1080i

HDTV, also known as the high definition television is actually a good change from the old and standard analog televisions. However, when it comes into choosing a certain unit, people are still troubled and they find it hard to choose one. Most of the question coming out is that, what is the big difference between 1080p and i HDTV? Actually, there are two kinds of HD broadcasts. These are the 720p and 1080i that uses resolutions of the 1280 x 720 or a picture being composed of 1280 pixels across and 720 pixels high. The p in 720p actually stands for the progressive scan. It only means that the picture is then painted from the top down to the bottom and in a single pass, refreshed or repainted for about 60 times per second.

1080p

It is the shorthand identification for the set of HDTV video modes being characterized by 1,080 lines of the vertical resolution, as well as progressive scan that only means that the image is not interlaced just like the 1080i standard display. The term actually assumes the widescreen aspect ratio of about 16:9 and implying horizontal resolution of about 1920 pixels. This resolution is then similar to the 2K digital cinema technology. The frame rate could be implied by the context or the specified one after the letter p like 1080p30. It only means that there is a 30 progressive frame for every second. There are also no broadcasts in 1080p and none is expected anytime soon. However, there are also digital formats that could produce original 1080p signal. HD and Blu-ray DVD players are some of the best examples.

1080i

The “i” means interlaced and it has big difference into the 1080p, in which the p stands for the progressive scan. The term 1080i actually assumes widescreen aspect ratio of about 16:9 and implies frame size if about 1920 by 1080 pixels.

The field rate of “i” is usually about 60 Hz for the countries that use or had used System M as the analog broadcast television system like Canada, United States, Brazil and Japan. Otherwise, it could be 50 Hz for the regions that truly used the television systems with 25 frames per rate. Both of the variants could be carried by major digital television transmission formats just like the DVB as well as ATSC.

Difference between 1080p and 1080i

The differences between 1080p and 1080i are some of the features that it could offer. The aspects that they could offer differ from one another. 1080p could show you clear mode for videos unlike what 1080i could offer. It is only the 1080p could display Blu-ray and HD DVD in its native and full resolution formats. There are also different models with various support modes. On the other hand, 1080i is a video or broadcast mode.

Recap:

1080p and i are identifications of the two different video modes used in TV displays.

The characters “p” and ”i” denote the scanning technique used and “1080” refers to the resolution.

“p” stands for progressive scanning and “i” for interlaced scanning.

1080p means the display has 1080 lines of the vertical resolution and the scanning used is progressive scan. The full resolution of the display is 1920×1080 pixels.

1080i means scanning is interlaced and the 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 denotes 1920×1080 resolution with progressive scanning and the frame rate is 30.

Interlaced scanning is an older technology whereas progressive scanning is what most commonly used now

Conclusion

Choosing the best television is never difficult, but it is also not an easy one. You just have to consider some things just like knowing the difference between 1080p and i. Knowing such could help you out about what is the best unit to take.

However, you need 1080p if you want high picture quality from your Blu-ray and HD DVD or using with your gaming consoles. This may be a needed for video editing also. For normal use 1080i is quite good, when compared with the price.
