Video Cable Definitions

In simple terms Video cables are cables which used for
transmitting video signal from one source to other. Sometime
these are called Coaxial cables because most of the video
cables available today are Coaxial cables.

Reasons for using different Video Cables

Different video cables are used for different purpose depending
upon their applications. Some of the advantages of using these
cables are:

1. Improving contrast ratio
2. Running cables longer
3. Getting less video distortion
4. Creating improved colors

Types of Video Cables

Types of video cables are based on its application. Some of
most popular types or video cables are:

1. DVI Video Cables
2. Composite Video Cables
3. RGBHV Video Cables
4. Component Video Cables
5. S-Video Cables
6. Portable Projectors Video Cables
7. VGA Video Cables

DVI Video Cables

DVI or digital video interface cables are slightly larger then
standard VGA cables. Ideally DVI cables creates digital link
between the source of video and display device.

Composite Video Cables

The most commonly used video cables are composite video cables.
These cables frequently used in Video Cassette Recorder and
stereo devices. These cables are color-coded namely red, white
and yellow where red is for right channel audio; white is for
left channel audio and yellow for video signal. Only one cable
is used for transmitting complete video signal. These are most
commonly used cables type inspite of their low quality
video/audio signals. The most common uses of these cables are
television, Camcorder, VD player, and VCR's.

RGBHV Video Cables

RGBHV Video Cables are similar to composite video cable but
difference is in the fact that video signal in RGBHV cables are
divided into five. These RGBHV cables divide the color of video
signal into red, green and blue. Now days most of the high end
monitors, HDTV used RGBHV connection to create the high
definition video quality.

Component Video Cables

In Component video cables complete video signals are divided
into three. This way it provides a better image quality then
compare to composite cable or S-video cable. Jacks tips of
component cables are Green, Red and Blue. Most of today's DVD
players, HD television sets tuners uses component cable
connections.

S-Video Cables

These S- video cables are also know as SVHS cables and have
variety of uses including latest television sets, satellite set
top box, camcorder and SVHS VCR's etc. S-video cables divide
video signals into two components like luminance and
chrominance. This is the main difference between S-video cables
and composite video cables.

Portable Projectors Video Cables

As their name suggests portable projector video cable needs
small room for connection. Due to this space scarcity most of
the portable projector cables comes with 15 pin VGA. The
projector is designed to sense the video signal it is receiving
and process them accordingly. These portable projector video
cables uses three out of 15 pins out connection designed for
component video signal.

VGA Video Cables

These VGA cables are normal monitor cables and have three rows
of fifteen pins. VGA cables are primarily used for PC to
projector or PC to computer monitor connections.
