What is the difference between interlaced and progressive video?
An interlaced picture is divided into two halves, the odd and even scans lines. These are "halves" are displayed odd, even, odd, even, etc., at a rate of 60 frames per second. So, in reality at any given time you are only seeing half of the picture (although because the frame rate is so high, your eyes don't notice it.) Interlaced scanning sometimes results in screen flicker and visible scan lines. Standard analog TV signals are interlaced signals.
Progressive scanning takes the whole picture (all scan lines) and displays them at a rate of 30 frames per second. Because the whole frame is reproduced every time, the result is a more solid, film-like picture. Computer monitors use progressive video on your equipment.
