1080i vs 1080p What is 1080p?
Can you tell the difference
between 1080i and 1080p? The
difference in the way the picture is scanned
and displayed on your HDTV set. The
i is for interlaced and the
p is for progressive.
The difference is that with
interlaced 1080i picture you see is scanned to
the screen in alternating lines, so your
HDTV will only get half of the
lines of the picture in the first scan and
the second half of lines in the second scan. This
all happens so quickly that human eye is tricked
into seeing a complete picture.
1080p Progressive scan
differs to this in that it scans all the lines at once,
thus giving a clearer and flicker-free picture. 1080p televisions display twice as many lines of resolution at one time.

In theory a progressive scan 1080p is superior to
interlaced scan 1080i. But most HDTV's like
LCD TVs and Plasmas TVs can't physically
display an interlaced picture... so what they actually
do when when using an interlaced picture it is
de-interlaced and convert it into a progressive scan
picture! So the argument goes that there is no
difference between 1080i and 1080p because
your HDTV will convert the 1080i signal into a
signal all through your HDMI
cables
But complications with de-interlacing cause problems,
some TVs don't do it correctly and you can end up with
less resolution than you started with. The TV's refresh
rate also help determine the quality of the HDTV.
HD-DVD or Blu-ray Disc players are
currently the only device on the market that supports a
full 1080p. Current digital television broadcast
systems and standards are not equipped for 1080p
transmissions... they broadcast HDTV in 1080i.
The resolution of 1080p televisions have the sharpest and smoothest images possible. If you thought HDTV looked good before...
You will be blow away with a 1080p television. And with a
1080p TV, you can take full advantage of the new DVD formats:
HD-DVD and Blu-ray.
We recommend buying a 1080p ready HDTV. But
remember one thing... don't ever believe the hype. It all
comes down to what looks the best to your eyes.. So do
the research online.. then get your ass out there to
your local HDTV retailer and check out all your
HDTV options.
