Difference between an RCA, DVI and HDMI cable

Difference between an RCA, DVI and HDMI
cable After recording your entire trip on your
newly bought camcorder, you come back and connect
it with your computer. You are excited to show
your friends and family the fun you've had. But
when you actually plug in your camcorder, the
picture quality is poorer than it was in
your camcorder. What could have possibly
gone wrong with your new equipment?
Well, it's not entirely your camcorder that
is at fault. The problem is with the cables
you are using. It's most likely that it's an RCA
cable you are using to connect the camcorder to
the computer. An RCA cable is a patch cable
that transmits analog or non-digital
signals. This type of cable is attached to
three jacks - usually red, white and yellow - red
and white for right and left audio channels
and the yellow one is the jack attached to
composite video.

The problem is that an RCA cable with just one
jack for video combines 3 signals (analog signals
are made up of 3 signals) and combines them into
one. This reduces the quality of the
video. Since, RCA cables transmit non- digital
signals you can't plug them directly to computers
or LED. Besides, if you have an HDTV, your
regular RCA cable would do you no good. It's only
worthy of an old VCR. But if there are
three RCA jacks transmitting the three
signals separately you would have a high
quality picture. This kind of cable which
uses separate RCA jacks for separate
signals, is called a component cable. This
kind of cable is ideal for your hi-tech
television and Blu-ray players. But what works
best with HDTV and in fact have been designed for
that very purpose is the Digital Video
Interface cables or the DVI
cable. A DVI cable is just like a component
cable except that it comes with High-bandwidth
Digital Content Protection. A DVI cable is
also compatible with the VGA format and can be
analog, digital or both. All these qualities
make it a preferred choice among
consumers for computers and for other high tech
equipment. An updated version of the DVI
cable is the HDMI cable. This works almost
like the former except the connect is
slimmer. So, what patch cable you are using
depends upon the type of signal you need
to

transmit. A DVI cable is as good as an HDMI cable
in transmitting signal for a HDTV, unlike what
many advertisers say. An RCA cable works only
where analog signal needs to be transmitted. So,
if you have an analog TV, either of the
three patch cables would work with it. Next
time you come across bad picture quality, you
would know where to look for sure.
