What is interlaced video and the benefits of interlacing
Interlaced video is a technique for doubling the perceived frame rate of video display without consuming extra bandwidth. Given a fixed bandwidth and high refresh rate, interlaced video can also provide a higher spatial resolution than progressive scan. For instance, 1920x1080 pixel resolution interlaced HDTV with a 60 Hz field rate has a similar bandwidth to 1280x720 pixel progressive scan HDTV with a 60 Hz frame rate, but achieves approximately twice the spatial resolution for low-motion scenes.
