In daily life, people often confuse 1080i resolution and 1080p resolution. In order to better distinguish between the two, the following is a detailed explanation of 1080i resolution.
What is 1080i resolution
1080i resolution has two parts, the number “1080” on behalf of the composition of the monitor vertical resolution of the horizontal number of lines, its pixel points for the 1920 × 1080. The other part of the letter “i” on behalf of the interlaced scanning, refers to How a 1080i monitor draws the image being viewed.
When it comes to the origins of 1080i, it can be traced back to Multi Sub Nyquist Sampling Coding, a Japanese analog HDTV system. Aside from that, it was also used on some older monitors, so let’s take a deeper look at how a monitor with 1080i resolution works.
How Do 1080i Monitors Work?
Once you know what 1080i resolution is, it is more intuitive to know how a 1080i monitor works. As mentioned above, with a 1080i monitor, the entire image is divided into two video fields.
Each video field contains one-half of the rows that make up the entire image: the first video field contains only the odd-numbered rows, while the second video contains only the even-numbered rows.
The two video fields will be displayed in an alternating pattern, enabling the human brain to reconstruct the entire image as one, without realizing that it is composed of two video fields. This is why 1080i displays are perfect for users who want to experience high-quality video with both motion blur and low-light visibility.
Uses of 1080i resolution
Nowadays, 1080p resolution can be found everywhere in life, such as in television broadcasting, the movie industry, gaming applications, and so on. But 1080I resolution is not so common.
1080i is the most commonly used HDTV format and has been adopted as the HDTV broadcasting standard by most TV broadcasting, cable and satellite channels. Secondly, 1080i’s often are used in sports broadcasting. The higher resolution provides more detail and clarity during large stadium shots and fast-paced action.
The format’s efficiency in utilizing available broadband makes it a practical choice for broadcasters. Overall, 1080i played a crucial role in the early days of HDTV.
1080i vs 1080p: Differences between
1080p resolution utilizes “progressive scan” technology, which means that each image is drawn in a single pass from top to bottom. Unlike 1080i, which splits each frame into two video fields, 1080p draws the image in its entirety the first time it is drawn.
Since 1080i and 1080p have similar resolutions and pixel counts, both 1080i and 1080p resolutions display 1920 x 1080 pixel images. The “p” in 1080p stands for progressive scanning, which means that the entire frame is displayed top-to-bottom, allowing for smooth motion and eliminating interlacing artifacts that are common in interlaced video formats.
The 1080i resolution “interlaced” method was originally developed for tube TVs to produce a flicker-free image with the smallest possible bandwidth. The difference between the two formats therefore lies in the way they are displayed on the screen.
1080i vs. 720p : Differences between
The first thing to understand about HD video formats is that there are several distinct resolutions. Technically speaking, 1080i is classified as Full HD, while 720p is classified as HD. In terms of resolution, 1080i has a resolution of 1080 lines, while 720p has a resolution of only 720 lines. Most people can feel the significant difference in picture quality between 1080i and 720p, so 1080i is objectively superior.
Frequently Asked Questions about 1080i Resolution
Do you still use 1080i?
Yes, we can often see “1080i” on satellite or cable HD signals. However, it is less common in some of our popular display devices.
What is the best resolution for a TV?
If the choice is between 1080i or 1080p, we can prioritize 1080p.
Will 1080p be superior to 1080i?
In terms of picture quality, 1080p will be superior to 1080i. 1080p provides better picture quality for fast moving images, thus avoiding blurring of the picture. Secondly, in terms of visual effect, 1080i will not perform as well as 1080p because of the different scanning method.
For playing games, choose 1080i or 1080p?
1080i resolution is usually used for TV broadcasting, so if the monitor is used for gaming, 1080p is the better choice. 1080p is considered the base resolution for gaming, and if it is lower than that, the clarity of the picture quality may be lacking.
For movies, choose 1080i or 1080p?
Although the resolutions of 1080i and 1080p are similar, 1080p is more suitable for movies, and 1080p is the best choice when recording fast-moving action scenes. Because 1080i can suffer from frame tearing due to interlacing, frames that are not aligned correctly can result in a blurry picture.
Summarize
Through the above introduction, I believe we have a clear understanding of 1080i resolution. Through the understanding of 1080i resolution, we can better promote the development of the display industry, to continuously evolve more high-resolution monitors.
