The interlaced method
involves refreshing pixels
in alternation—first the
odd lines and then the
even lines.
With the progressive
method, every pixel on
the screen is refreshed
simultaneously.

What is the Screen
Resolution?
The screen resolution indicates the amount of detail that the picture displays.
Resolution is identified by the number of display lines on the screen. The
techniques that an HDTV uses to “paint” the picture on the screen are referred
to as progressive and interlaced.
For example, a resolution of 1080i indicates that the screen shows 1080
lines in an interlaced display, and 480p means that the screen shows 480
lines in a progressive display.
Note: The screen resolution (1080i, 480p, etc.) is sometimes referred to as
the scan rate. The terms are interchangeable.
