Techopedia Explains Progressive Video

Progressive video is also known as 480p, where p stands for progressive scan signal. This is a method to display images on a TV screen. This is largely used in CRTs, HDTV displays and computer monitors. It provides a more detailed image on the screen and is clutter free. This is the reason that it has high bandwidth requirements, which was initially a limitation, but is not anymore.

In order to use progressive video, it is required that both the display and the source are compatible with progressive scan. In this process, the entire image is refreshed in every cycle. For example, with a progressive scan video at 60hz, the entire image would be refreshed 60 times per second. The fast transitions result in a smooth image.
