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.

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 ...
