Interlaced video. Illustration of an interlaced scan pattern. Animation of an interlaced TV display, showing odd and even fields being scanned in sequence, to display a full frame. Interlaced video (also known as interlaced scan) is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth.
Progressive scan has always been a more simpler method, and interlaced scan appeared only due to technical bottlenecks of the past time. Transmission bandwidth no longer presents a problem today so progressive videos and screens dominate the market. The only remaining interlaced videos are usually found in old videos.

Dec 15, 2016 · 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 ...
Jul 9, 2022 · Broadcasting interlaced video was cheaper than broadcasting progressive-scan images but also resulted in lower quality images with a higher risk of artifacting, flickering, and other visual imperfections. With only 50% of the broadcast lines visible at any given time, the transitions between the odd and even lines often resulted in inferior images.
Aug 18, 2023 · Key Takeaways. Interlaced scanning is still used in some broadcasts because it saves bandwidth and allows for more visual information to be displayed without increasing transmission size. Interlaced video scanning can result in visual errors, like interline twitter, but progressive scanning is more stable and less likely to have issues.
May 10, 2021 · Progressive video and how it differs from interlaced video. Unlike interlaced content, progressive video is a video track that consists of complete frames. There is a slight asterix to this statement as techniques like interframe can be used to compress video content to remove redundancies from frame to frame (read more about the interframe ...
In the interlaced video, each displayed frame consists of two interlaced fields. For example, frame 1 consists of field 1 and field 2, with the scanning lines in field 1 located between the lines of field 2. On the contrary, the progressive video has all the lines of a picture displayed in one frame. There are no fields or half pictures as with ...
