Have you ever missed your favorite TV show or a last second 3 pointer in a basketball show? Fear no more! DVR is there to save the day!!!





My report will cover four interesting ideas.  First, I will write about what DVR is and what DVR does.  Next, I will explain the naming!  Then I will write about when DVR was first used!  Finally, I will end with a short summary of how DVR works!  So if you are interested in my report, go ahead, read on!

What DVR is and what DVR does

This paragraph is about DVR! What it is, and what it is used for!

DVR is used to record channels or shows you want to see later in the day!  (It is very useful to couch potatoes!)

Karl D. Stephan said that they fixed the problem of fussing with tapes!!!





First, a DVR is tape less. With a VCR, the device itself is merely a recording tool; the blank cassette is the media. In a DVR, media and tool are one and the same. This is obviously a plus if you never seem to be able to find a blank tape when it comes time to record something, but it can also be a drawback: Because the media is hard-wired into the machine, adding additional storage space is not possible. (There are Web sites that offer instructions on how to open a DVR and add a new hard drive, but beware -- this will definitely void your warranty.) Getting more recording time is easy with a VCR -- just buy another box of blank tapes. More recording time on a DVR involves buying a new unit.

The Naming

DVR has 2 names, DVR, and PVR!

DVR (digital video recorder) means that it’s a digital, video recorder! That’s simple enough, isn’t it!  PVR is basically the same, it’s just putting a P instead of he D!




Karl D. Stephan, (Mr. Smart Guy) said that it has 2 names himself!

Way Back Then

This paragraph is about when DVR was first used!




People think that it is a new invention!  But nope!

Ken C. Poleman said that DVR was first used in the 1950’s!

How DVR Works

This paragraph is about haw DVRs work!

In a nutshell, a DVR is a glorified hard drive inside a fancy box that looks nice in your entertainment center. The hard drive is connected to the outside world through a variety of jacks on the back of the box, usually the typical RCA connections that you would use to hook up, say, a cable box or a VCR.




So you get how complicated that is!

DVRs allocate a certain portion of the hard drive to a live TV buffer. They are constantly recording, and generally keep the past hour or so in the buffer. This means that if you walk into the room 10 minutes into a movie, you can rewind by 10 minutes and catch the beginning -- provided the DVR was on the desired channel (the buffer is emptied each time you change the channel, and the DVR starts recording again).


In conclusion, if your family is dying to see a show, don’t forget about your handy DVR!!!







I hope you enjoyed learning about DVR.  I know I enjoyed learning about how it works!  Always remember how many names it has and when it was invented!
