DVR Introduction
A digital video recorder (DVR) is
basically just a computer hard drive that is encased in a box that
is made to look like the other electronic components that are stacked
in your entertainment center.
The memory device is connected to
other components of your entertainment system through a set of jacks
that are located on the back of the DVR. These are typically your
normal RCA jacks that are used to make connections with a satellite
TV receiver, DVD player or VCR. Some of the more modern satellite
TV receivers have a built-in DVR. It can even be used in conjunction
with high definition broadcasts.
Having a digital video recorder (DVR)
will allow you to be able to record TV programs without using videotape.
The information is digitally recorded to the hard drive of the DVR
unit. It's like a DVD player that doesn't require the use of DVD's.
Plus, most DVR systems have a lot of bonus functions.

Technical Aspects
of DVR Functioning
Recording digital satellite TV signals
on a DVR is a more complicated process than recording broadcast digital
or analog signals. The process is complicated simply because the MPEG-2
or MPEG-4 streams that are used need to be encrypted so that people
can't view the satellite TV programming content without having a subscription.
Some DVR receivers are so technologically
advanced that they will even allow you to use an on-screen caller
ID function. When you setup services with a satellite TV service you
will need to be hooked up to there service over the phone. They use
the phone in order to communicate with your system (So you can get
Pay Per View). The on-screen caller ID function will allow you to
be able to see who's calling your house, right on your television
screen.
