Comparison between 1080i and 1080p
This article will help you make the difference between 1080i and 1080p.
When you are out for purchasing a new television set, you will learn that the first thing you should ask about a television is the resolution. This involves the quality of the image, the details and the clarity, so as you can see, the most important features.
First of all, let’s understand what ‘1080’ refers to. It refers to the resolution, more exactly to the number of vertical pixels that the TV can display while the horizontal pixels are ‘1920’. This means it has a resolution of 1920 x 1080. This is presently the highest resolution possible for a television and it is the same for both 1080i and 1080p. The only difference is in the scanning technology. So here is where the ‘I’ and ‘p’ come into discussion. The ‘i’ refers to ‘interlaced’ scanning and the ‘p’ to ‘progressive’ scanning.
In terms of technology, progressive scanning is more superior. Here, the video image is rendered by scanning 1080 lines in 1/24th of a second sequentially. This is what ‘Full HD’ is today. Also this represents the best video recording for good cameras.
The interlacing scanning generates the image by using two fields of lines one with odd and one with even lines. The odd lines are displayed in 1/30th of a second and then the even numbered lines are displayed next.
The image in a 1080p TV is more stable and less flicker. The quality with which it displays fast moving images is far better.
