Progressive Scan DVD Players
You've probably heard about progressive scan DVD players,
but you may not know what exactly they are or why they seem to
be the hot item that people want these days. To understand why
this is the case, first you need to learn about the different
technology that progressive scan DVD players provide. And then
you'll need to realize that at the moment, only those who have
invested in HDTV or other high performance display
screens or projectors will be able to take advantage of the
difference.
To start with, let's review the way that traditional motion
pictures are created. In fact, the term 'motion picture'
is rather misleading because no pictures actually move. Instead,
still pictures, also called frames, are played in
rapid succession so that the resulting display is
changing so quickly and in such small amounts at a time that we
perceive it as moving. You may have recreated this illusion in
school or on your own by drawing stick figures or other pictures
on a stack of paper, then flipped through the paper quickly. The
figures looked like they were moving rather jerkily. But if you
took the time to draw enough frames and move them quickly
enough, you would see much smoother motion, like in cartoons.
Television is recorded in the same type of frames. Then it's
broken down to be transmitted in a signal. When the signal is
received by your television, it is reassembled in sections, or
stripes. These stripes are reassembled in two different sets,
from top to bottom and left to right across your television
screen. To explain this concept more clearly, imagine window
blinds that are partly open. The actual blind pieces are one set
of stripes and the space between the stripes represents the
second half of stripes. In a TV transmission, the stripes of set
one are laid in before the second set is laid in. This is called
an interlaced display. Although it sounds like it would
take some time, all of this happens in the fraction of a second
-
60 of the fields or stripes are displayed per second.
DVD players and DVDs have used this same technology because of
the fact that TVs displayed pictures this way. But with the
advent of digital and high definition television
projectors, display technology has changed, leading the way
for DVD technology to change as well. These high performance TVs
and projector screens receive and display signals in full
progressive frames instead of stripes. And 60 full frames are
displayed per second. Meaning even more detail can be included
in the same amount of time, resulting in pictures with less
flicker or picture distortions. Progressive scan DVD
players work by sending DVD signals in the same progressive
format.
However, progressive scan DVD players only make a difference if
they have both the source material that can be scanned into
progressive signals and the display screen that can receive
progressive signals. Older DVDs were most likely not recorded
with progressive signals. Newer ones will have the capability,
though. But as mentioned before, you have to have a television
that can receive progressive signals. HDTV televisions can, and
so can CRT or LCD monitors.
If you have the right kind of television, a progressive scan DVD
player, and a DVD that was produced in the last 5 years or so,
you can test to see if you can tell an improvement. Just switch
the DVD playing setup from progressive to normal as you watch
the film. Look at the outline of things, and the details of the
background elements. You may just experience home video with a
clarity and sharpness like never before.
