Progressive Scan Video

A recorded video image consists of horizontal scan lines, with the number of scan lines ultimately determining the resolution, or quality, of the video image. Rapidly scanning these lines across the display, starting at the top of the screen and moving to bottom, produces each frame of the video image. Instead of displaying the scan lines as two alternating fields (interlacing), progressive scan allows the lines to be displayed sequentially, meaning that both odd and even numbered scan lines are displayed in numerical sequence producing a complete frame of video.
