PAL, both of which send alternating half-pictures that are displayed with
the lines offset against each other, to form a fully illuminated picture on
the screen. On a computer monitor you can see a comb effect in horizontal

jitter, or bouncing, on stationary horizontal edges if they are very sharp.
