Visual quality. It's the difference between a TV and a PC monitor:
interlaced vs. progressive. A TV with 480 lines of resolution doesn't show
all 480 lines for every screen update (1/60th second). Instead, a TV
displays only 1/2 the picture every 1/60th of a second. The first "field"
is comprised of the odd numbered lines and the next field is the even
numbered lines. It takes two fields to build ONE full frame of video.
Although it's fast, you never actually see one full frame of video at the
SAME TIME.
Progressive scan shows a full field of video EVERY 1/60th of a second. That
means all the visual detail of the full frame EVERY SINGLE FRAME. Since DVD
movies are recorded in 24 frames/second progressive scanning also includes
3:2 pull-down to convert 24 full frames to 60 full frames per second. A
simple explanation is the TV alternately displays frames of DVD 3x then 2x
then 3x, etc., resulting in 60 full frames per second.
As you can imagine the picture is smoother, sharper, and has no motion
artifacts or jaggies. For DVD movies you get that "film" look where skin
tones are smooth and "creamy" (very natural and realistic), color is
saturated, and everything is just more richly detailed. If you're someone
who has a keen eye you will absolutely see the difference between
progressive and interlaced DVD.
Regarding console ***, most Xbox games are 480p (progressive) so the
graphics are remarkably nice for TV ***. The avg Xbox game runs at 60
FULL FRAMES of animation per second. It's very impressive to say the least.
