DVI DVD Player Buying Guide
In the late 1990’s a new consumer digital format changed the way we look at entertainment in the home
forever. This format combined incredible picture and audio quality, feature rich software, and interactivity
at an unheard of price point. This format was DVD and over the years the technology has progressed in a
fashion that has made this format even better today then ever before.
Component Video and Progressive Scan
The first DVD players on the market relied on the traditional analog video connections we had grown
accustomed to with VCRs and Laserdisc players. But DVD brought a new connection to the market;
component video. DVD players were the first consumer video product that offered this output. Component
video offered more bandwidth for color resolution and required less processing from the end display
resulting in a far more detailed and vibrant image then what the average consumer was used to.
A few years later this output was further enhanced by the introduction of capability called progressive
scanning. Progressive scanning combined the interlaced fields we were used to seeing from DVD and
offered unprecedented clarity and smoothness. Gone were the horizontal lines that we were so used to in
our traditional video systems.
But as good as component video and progressive scan playback are, there are some obvious compromises.
DVD is an inherently digital format. The video information is mastered in the digital domain and stored
digitally on the disc. Normal DVD players decode the video data and then do a digital to analog conversion
and then send that data through several analog filters before it ever reaches your display. Once the display
gets that analog data it coverts the analog information back to digital for further video processing. Some
displays, like traditional CRT based rear projection TVs, even convert the digital information back to
analog again further filtering the image. All of these conversions and filtering take their toll on the final
image robbing it of some of the detail and luster it is supposed to have.
DVI – The Digital Advantage
With today’s market moving more and more into the digital domain the need for a digital interface has
become readily apparent. The traditional CRT based displays we all grew up with are becoming harder to
find and new technologies like LCD, DLP and plasma are the new deal. In order to take full advantage of
these technologies DVD players need a digital video connection that will remedy the shortcomings we’ve
grown so used to.
One of these solutions is DVI (Digital Visual Interface). This connection is already quite popular in the PC
world and has now found its place in the consumer video market. This connection supports much larger
bandwidths than our traditional analog connections allowing for some great new features.
Because DVI is a pure digital video interface most of the shortcomings inherent in our traditional analog
processing are gone. DVI allows the signal to stay the way it was intended to be all the way to the end
display and this results in a far more compelling image that is razor sharp and wonderfully vibrant. DVDs
can now be seen the way they were truly meant to be.
How do I choose a DVI DVD player?
There are lots of companies offering DVI based DVD players but most of them are not taking full
advantage of what DVI brings to the table. Because of the added bandwidth and robust copyright
protection, DVI allows DVD players to scale their images to the same resolution as HDTV. This is a must
