Progressive Frame
Interlaced Scan first displays the
odd numbered video lines on the
TV in 1/60th of a second
Interlaced Scan then displays the
even numbered video lines on the
TV in 1/60th of a second
Progressive Scan displays all the
video lines of each frame at once
on the TV in 1/60th of a second for
sharp, flicker free video
De-interlacer

480I Video
The conversion to interlaced video is necessary for viewing on a standard TV but has
negative effects, like loss of resolution, noticeable scan lines and increased flicker, as
shown in Figure 3.
Interlaced Video
Interlaced pictures have noticable
TV scan lines, flicker and is 1/2 the
resolution of the orignal video
