That's for DVD. TV broadcast in North America is low res until we all
have HDTV. I believe the UK has the highest broadcast TV res in the
world.

720 X 576 (480 NTSC). Used by most DVD.

NTSC Broadcasts (composite) ? 120 lines best, 40 - 48 lines typical
for reddish orange and greenish blue; 40 - 48 lines for most other
color transitions.

The number of lines of horizontal resolution in NTSC broadcast video
is about 333 lines across the screen. Think of being able to display a
maximum of 166.5 pairs of alternating black and white stripes, drawn
vertically on the screen. That's the horizontal luminance resolution,
so it only covers the resolution of the black and white detail of the
image. Many television makers neglect to mention the "luminance" word
when giving their specifications, and incorrectly describe their lines
of resolution specification value as covering everything. It does not.
