Progressive Scan

A video term that describes a method of displaying images in which every horizontal line is drawn on the screen in a single pass to create a complete frame or single full-screen video image. This is different from interlaced video, in which each video frame is created by drawing two fields, one of which is made up of the odd numbered lines and the other the even numbered lines. Traditional television video uses interlaced scanning. With the advent of digital video and high definition video, progressive scan technology has become much more common. Computer monitors have used progressive scan (calling it “non-interlaced”) for quite some time.
