At CEDIA 2001, it seemed as though the number of new DVD
players with progressive scan equaled or exceeded the number of new models without it.
Progressive-scan DVD players now come in all price ranges, even the lowest tier. One of
last years progressive-scan models is selling at some Internet retailers for as
little as $149.
Bear in mind that you cant get any benefit from a progressive-scan DVD player
unless you own a video-display device that can display progressive-scan images. Normal
televisions cannot do this. In most cases you will need a DTV (digital television) or a
HDTV (high-definition television) product in order to be able to display progressive-scan
images. Some analog-projection hardware, especially those adapted from products originally
made for computers, can also display progressive-scan images.
You already want to know which DVD players in various price ranges have the best
picture and sound quality. You may be interested in knowing which DVD players sound best
when playing your stereo music. Now, if you decide to get a progressive-scan DVD player,
you need to know what progressive-scan performance you are getting for your money. That
is a difficult question to answer for any home-theater publication. Player models change
rapidly, being replaced by newer units every time you turn around. You may be shopping at
a time when one companys models have been out for almost a year while another
companys are brand new with no published reviews yet. How do you have half a chance
of knowing just what you are getting for your progressive-scan DVD-player dollar?
At the CEDIA show in September 2001, the Home Theater & Sound and SoundStage!
crew saw an amazingly good demonstration of the differences between and among three
progressive-scan DVD players. The demo easily revealed some of the performance
characteristics of different progressive-scan chip sets. Best of all, the demonstration
was done using a DVD that you can get for free!
Kenwood demonstrated their Sovereign DVD players that incorporate the Faroudja DCDi
progressive-scan chip set. The five-disc Kenwood Sovereign DV-5900 lists for $1200 and the
400-disc DV-5900V lists for $1500. As you might expect in a demo performed by the
manufacturer, the Kenwood Sovereign DVD players passed the image torture tests with flying
colors compared to two competitive DVD players, which employed the Genesis and DVDO
progressive-scan chips. The test sequences consisted of specially composed images, some
shot on film or video, some computer generated. The tests deal with the behavior of the
progressive-scan chip sets when there are small areas of the image that are different in
nature from the rest of the screen. For example, a shot of a tall building with a waving
flag in the foreground is used. The stationary background surrounding a moving object
caused the other two chip sets to introduce significant levels of jagged edges into the
straight lines of the flag. Another one of the computer-generated screens consists of a
black field with two sets of stationary horizontal white lines in the top 1/3 of the image
-- one set of lines were "even" numbered scan lines while the other set were
"odd" numbered scan lines. A stationary "0" character was at the
bottom center of the image. A small logo in the lower right corner of the image rotated
(the only motion in the image). While the logo is stationary, all three DVD players
produced identical images. As soon as the logo was set in motion, the Genesis- and
DVDO-equipped DVD players introduced flashing or flickering of the horizontal lines (as
the chips were confused by the small area of motion when nothing else in the image was
moving).
You can get the
Kenwood Sovereign demo DVD by going to the Kenwood USA Website at kenwoodusa.com. When you are at the
site locate the "Kenwood Sovereign" logo (as shown right). Click on that and
youll go to the page where the disc can be ordered. Its always great to be
able to tell readers about tools that provide real-world assistance in helping answer
practical questions. Thanks to Kenwood Sovereign for making the demo DVD available.
Its a tool that many will find extremely useful for evaluating one of the more
difficult-to-get-a-handle-on performance characteristics of the new wave of DVD players.
If you dont have a progressive-scan display and dont have a
progressive-scan DVD player, there is little on the disc that will help you evaluate the
performance of your equipment. The test section is strictly designed to show the
differences in progressive-scan logic used in various progressive-scan chips that are in
different DVD players. Of course, if you want to find out more about the new Kenwood
Sovereign product line, the DVD includes a complete audio/video presentation on the full
product lineup. Additionally, there are some demo 5.1 music tracks (Dolby Digital only)
and some demo music video tracks (Dolby Digital 5.1 only). Its a bit awkward
navigating the test-image section to get to the particular test you are interested in, but
for the cost, none, Im sure not going to make that much of it. If you are going to
shop for progressive-scan DVD players, this disc reveals processing differences so clearly
that you should be able to tell which players are doing the best job in regards to
progressive-scan decoding even if you have to view the tests in different stores on
different displays with different lighting conditions.
