1080 Interlaced (1080i)

Definition - What does 1080 Interlaced (1080i) mean?

In IT, 1080 interlaced (1080i) is a term for a type of display improvement technology to complement high-resolution images. These types of strategies are commonly used in streaming video, in order to provide a better visual result to viewers.

Techopedia explains 1080 Interlaced (1080i)

One way of explaining the 1080 interlaced technique is to contrast it with another similar format called 1080 progressive. Both of these operate with 1920×1080 pixel resolution. The difference is that the 1080 progressive format displays all of the pixels on the screen at one time, but the interlaced format displays two sets of pixels, one after the other. In a 1080 interlaced format, one image is broadcasted over the even lines of a pixel field, and the second image is broadcasted the odd lines of pictures. This technique helps to make motion seem to flow, and can reduce issues like screen flicker. The 1080 interlaced format is often broadcasted at 60 frames per second, but with the split display, it might be more accurate to say that it is broadcast at 30 frames per second.

With 1080 interlaced techniques, the results can vary depending on several factors. A smaller television can minimize the difference between progressive or interlaced formats. It is also important to look at the way provider companies handle the compression of data. And of course, there is the screen resolution, which is a different issue from whether or not broadcasters are using an interlaced or progressive format. However, 1080 interlaced has become part of a gradually evolving standard for high-definition of television displays.
