Video Scan Type

The scan type refers to the video being either interlaced (720i) or progressive (720p).

Why do we test it?

Progressive scans transmit all lines of a video at once, and yields high quality. It's the common scan type for the web today. 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 (the even lines will be displayed on a viewer's screen, THEN the odd lines will be displayed; not simultaneously).
