Well, Progressive scan is the opposite of Interlaced scan.

1080i = 1080 Interlaced.
1080p = 1080 Progressive.

Interlaced scan wites every other scan line of the picture (let's say
the odd-numbered ones, 1,3,5,...) in half of a frame time, then goes
back and writes the other half of the lines (obviously in this example,
the even-numbered ones, 2,4,6,...). Thus a frame is made up of two
fields, as they are called.

Progressive scan writes all of the lines in one sweep, 1,2,3,4,...

A TV must be built to do progressive or it can't.

If your TV can't do progressive, then progressive won't improve the
picture (mild humor there).
