Distributing Video Over Cat5 and Cat7: Things You Need to Know About Video Distribution Through Cat5 or Cat7

When thinking of setting up your home video system, it means that you should know something about distributing video over CAT5 and CAT7 because it is the kind of system that will broadcast optimum performance. It also means that you can now have your source from a distance away from the display device, television or monitor.

There are three (3) general types of video distribution system:
1) Analog or Baseband
2) Internet Protocol
3) Radio Frequency

Any of these types may use coaxial cables, category 5 or more commonly known as CAT5 cables, CAT5e, CAT6, CAT6e or CAT7 cables. What are the differences between them?

1) CAT-5 distributes video up to 100M.
2) CAT-5e 350M.
3) CAT-6 and CAT6e distributes video as far as 550M to 1000M
4) CAT-7 is rated from 700M to 1000M.

Viewing Video Over CAT5 or CAT7

Video over CAT5 or CAT7 like those delivered by CATV, data, and telephone are all distributed in similar wiring closets. It delivers videos that may run along a distance of 100M for CAT 5 or even up to 1000M for CAT7. Video over CAT5 or CAT7 all goes out on the same cabling system. The system is channeled in a passive broadband balun that converts any uneven coaxial signal into a balanced signal through the video over CAT5 or CAT7. Even when distributed to different channels simultaneously, it will not slow down the network because the air analog signals do not travel on that similar network, and thus, it does not rely on the bandwidth of the video signals.

Presently, the use of FTP or UTP cables for audio and video needs is prevalent. Instead of using coaxial cables, CAT5 and CAT7 cables are used. Coax are first installed into the hubs and everything else is distributed through the FTP/UTP. Video over CAT7 or CAT5 for that matter are now possible at a limited cost. There is ease in the installation and location change is not a big deal. All one needs to do is connect patch cords from the distribution hub to the patch panel and have a single port converter connected to the television.

Advantages of a Video System Using CAT5 and CAT7

1) Video over CAT5 or CAT7 is cost effective as it eliminates the need for additional coaxial cables.
2) Configuration of video over CAT5 or CAT7 is much easier than having multiple splitter taps, amplifiers and combiners of coax.
3) A high quality signal is maintained as the distribution system of video over CAT5 or video over CAT7 uses active RF video hubs. It makes automatic slope adjustments hence all video channels’ image quality is sustained.
4) The video distribution system of CAT5 or CAT7 can carry out voice and auxiliary signals simultaneously. There are no interferences between the voice and video data.
5) A system with video over CAT5 or CAT7 allows video streaming from the computer and it is made possible through a broadband video system.

Distributing video over CAT5 and CAT7 is made possible through an RF broadband system. It broadcasts CATV, HDTV, internally generated video, video-on-demand services, and satellite videos through twisted pairs of CAT5 or CAT7 cables.

Know the difference of how your video system will work. Systems working with video over CAT5 and systems running video over CAT7 will have their own advantages and disadvantages that you have to evaluate.

So they are not able to harm the TV set. Normally the mid range frequencies are being handled by this speaker.


Rear channel speaker


This speaker is placed according to the seating arrangement of the listener. The speaker models also define the placement arrangement of this speaker. For instance, in a 5.1 surround sound set up, there are two such speakers and they are placed right behind the listeners. Four speakers are allotted for the 6.1 version.

Audio Books And Recorded Books: Do You Know The Answers To These Questions

You’ve heard of audio books, or recorded books before, haven’t you? Many people, even the ones who use them daily, remain tongue-tied when it comes to answering correctly the following questions.

Why? My guess is that audio books in general are so convenient to use. Many of us prefer to venture into the scenes of an audio book without delay more willingly. Spending our precious time researching every detail about its creation remains a distant “maybe”.

On the other hand, there are a few details about recorded books you want to know.
What for?
’Cause knowing them makes it easier for you to navigate around audio books with more confidence. Your improved “shopper’s education” to make the right choice is worth it.

I admit I used to be unaware of even the basic terms about audio books myself. So, I asked questions to get answers.

Guess what? I’ve found them. And I’d love to share them with you so you can save time researching the same questions. If you’d like to know the answers to the following basic questions about audio books, keep on reading.

What’s an audio book?

An audio book is a book in audio format. It is a “fun replacement” for a physical hardcover or paperback book you’d read from cover to cover. Instead, you grab-n-read books on CD, books on tape, or MP3 books versions.

What formats do audio books come in?

You can get recorded books on tape, books on CD, and MP3 books. From an old-fashioned cassette player to modern and sleek MP3 players, audio books keep you company on-the-go where traditional book reading is simply unsuitable.

What’s an MP3 book?

MP3 books are still audio books. But a clever compression technique reduces the file size to take up less recording space. Besides that, MP3’s are portable and easily downloadable. Storing them is a breeze when compared to piling up stacks of cassettes or CD’s.

How can recorded books in MP3 format be played back?

You can play MP3 audio books on any MP3 portable player. You can also play them on your home PC (need to have Windows Media Player or similar). Playing MP3’s on a laptop or MP3-enabled cellular phones is the latest trend. If you don’t have an MP3 player, but have a CD player, you can burn MP3 files to a CD using your computer. You’ll need special software to do that. Search Google for “free software to burn CD’s” :) .

What does “unabridged audio book” mean?

Good question. An “unabridged” audio book is narrated (or told) word for word. It’s the printed book equal in audio format. Nothing’s missing. Nothing’s added. As a result, they are longer than “abridged” versions.

What’s an “abridged audio book” version then?

It’s similar to the printed original, but shorter. The word-for-word narration from the previous example is not exact. “Abridged” also means shortened, cut. Keep that in mind if you are looking for the original version.

What are “dramatized audio books”?

Dramatized audio books are stage-like, “play-life” versions of printed books. You get all the bells and whistles: full cast, music and sound effects. Some people prefer it; some would rather get a simple, told version by an experienced narrator.

Is there a difference between having the author of the physical book tell the audio version, or is it better to have a professional narrator do the job?

Some authors are gifted for both writing and telling their own book. Others are better off leaving it to professional “voice-over calibers”. If you can, listen to a sample of the recorded book that catches your interest. It’ll help you decide if the narrator resonates with you. Some people swear that half the beauty of an audio book is the voice-over quality.

Where’s a good place to start for a novice interested in recorded books?

An excellent place to start is to pick up a favorite story you already know about, but would like to “read” as an audio. About the length, pick “abridged” audio books to start with to cut down on time they take to play back. Once you become more skilled with recorded books, you got to check out “unabridged” editions as downloadable audio MP3 books as soon as you can.

Once a beginner, Lou Smith shares the riches he’s found in Audio Books. He offers you a special invitation to get free Recorded Books as gifts now. You can listen to MP3 books as well.
