Being high-definition formats, 1080i and 1080p are commonly used when describing HDTVs and Blu-ray Players. Understanding between them can get a little confusing. 1080i and 1080p both produce a video signal of a 1920×1080 pixel resolution – 1920 pixels going across your television screen and 1080 pixels going down your television screen. (Pixels are tiny dots which make up the image on your screen) The difference between them is in how the 1080i and 1080p video signal is displayed on your TV screen.

With the 1080i high-definition format the video for individual frames are displayed in alternative fields. The field consists of 540 lines of pixels going from the top to the bottom of your TV screen. First displayed are the odd fields, then the even fields are displayed. Once combined they create, every 30th of a second, one solid full frame composed of all 1080 pixel lines.

With the 1080p high-definition format the video is transferred or displayed progressively. What this does is display both the odd and even fields that make up the 1080 pixel lines or one full frame, at the same time. The resulting image is significantly clearer and sharper looking than the 1080i image. It has far less motion artifacts or jagged edges. Click Here to Read More About 1080i vs. 1080p.
