Interlaced video (also known as interlaced scan) is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth. The interlaced signal contains two fields of a video frame captured consecutively.
An interlaced display, or interlaced scan video, is when a video only changes every other row of pixels in the image at each screen refresh. The lines are scanned alternately in two interwoven lines. Interlacing is used in broadcast television to reduce the amount of bandwidth needed for each frame but still maintain a high refresh rate.

Interlaced. A common way to compress video is to interlace it. Each frame of an interlaced video signal shows every other horizontal line of the image. As the frames are projected on the screen, the video signal alternates between showing even and odd lines.
Dec 15, 2016 · What Does Interlaced Video Mean? Interlaced video is a process wherein the frame rate of the video is doubled without affecting the bandwidth. It refers to one or two standard procedures used for displaying a video visual or an electronic display monitor, by scanning each line or row of pixels. This technology particularly came into wide use in ...
Apr 6, 2009 · Interlaced video is a technology that was developed in the early days of television, to fit a watchable picture into the available bandwidth of the time.
Interlaced video scan shows even and odd scan lines as separate sets of lines, so the odd lines will be displayed on the screen first, and the even ones will fill in after. You effectively double the perceived frame rate without providing more information by presenting every other video line.
Sep 8, 2023 · 1. What is video interlacing and how does it work? Interlacing splits each frame of a video into two fields, one containing odd lines and the other containing even lines. These fields are then displayed alternately to create a complete picture. Let's take a closer look at how video interlacing works.
