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 the early
days of television in order to fit a picture into the desired bandwidth. An
interlaced video is refreshed twice every frame. Initially, even scan lines are refreshed
followed by odd scan lines.
Interlaced video is also known as interlaced display.
Techopedia Explains Interlaced Video
Interlaced
video is a procedure used for amplifying the anticipated frame
rate of a video display without the need for additional bandwidth. The interlaced
connection consists of two ranges of a video fixture apprehended at two
separate times. In short, every alternate line is scanned to make a complete picture.
The two fields are then perceived as a continuous image due to persistence of
vision. However, an interlaced video has some restrictions. It needs to be stored,
displayed, captured and transmitted in the interlaced format. Since the video
consists of video frame captured in two different moments of time, the video can
exhibit motion artifacts called combing.
