Question:

What is Progressive Scanning?

Answer:

Progressive scanning is typically used by computer monitors. This scanning process paints all the horizontal scan lines on the screen at one time. The other common scanning scheme used in HDTV is broadcast at 750 progressive lines, of which 720 of those lines are visible (hence the term 720P).Some television broadcasters have chosen to broadcast 525 progressive lines, of which 480 of those lines are visible (hence the term 480P). Many DVD players output the picture in 480P format.
