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. This enhances motion perception to the viewer, and reduces flicker by taking advantage of the phi phenomenon.
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.

Jul 9, 2022 · Interlaced is the alternative scanning method to progressive scan. With interlaced scanning, lines of visual information are alternated as odds and evens. Only half of a frame’s visual information is broadcast at a time (i.e., the even lines will be displayed on a viewer’s screen, THEN the odd lines will be displayed; not simultaneously).
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.

What is Interlaced Video? 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. In addition, quickly ...
Apr 6, 2009 · Doug Graham and Morris. What do people mean when they talk about “interlaced video”, and why is it important? 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.
