What Is An Rgb Cable ?
If you need a good “accessory” that is able to transfer your device’s analog video signal from the preferred video player or source to a nice display, an rgb cable might simply be your best choice.
Why I say this ? The answer is simple, it can be used in conjunction with any type of dvd players, portable dvd players, blue ray players, laptops, computers, gaming systems, you name it.
They are one of the most common cables used for connecting your computer’s video card to the monitor or different cameras to TV’s, HDTV’s.
Characteristics of an Rgb Cable
It is a necessity because of it’s current wide uses. Now going further to characteristics, the common RGB cables usually use a multi color adapter that is formed by multiple colors like blue,green,red that are syncing together as horizontal and vertical information blends and it will give your image on the screen.
More easy explained,the 3 separated input and output connectors that are on an rgb cable will try to carry different signals. These signals vary from red,blue to green.
These different analog component video standard also known as rgbhv, rgbs, rg&sb don’t use compression and as I know, they don’t have a limit in how many colors they can display but the single requirement for the amount of colors that they display is the available bandwidth that will be used to carry the signal and it will contain redundant data.

We spoke of the ability of an rgb cable to display the video signal that comes from your computer, directly to the screen. This is done using the common VGA port.
The vga connector also known as a video graphic array is exactly a 3 row 15 pin de 15 connector.
Not many people know this, and thing of an RGB cable as a simple cable because they are used to it without asking more details. But did you knew that this adapter will try and succeed in filtering your signals and also separate them with the delegation of the transfer of what comes to it ( mainly colors and decoding video signals ) and giving them on the screen.
Knowing all these, can you imagine your hi-def tv on your great screen without the help of an rgb cable ?
Most Common RGB cable ?
One of the most used rgb cables are found on various consumer electronics names ypbpr. The method in which this type of cable transfers the color and the sync is different from a standard rgb cable. Instead of going default with the red,blue,green solution and h per v synchronization transfer, there are plus two different signals used : luma and chroma.
You will put the question why this change. The answer is because this will help in cases where your bandwidth is limited because the Y will carry the luma data which at it’s turn will control achromatic ( this means the colors ) brightness.
The Pb cable will be used for helping with the blue chroma signals, with the help of the pr cable that will carry the red chroma.
The current supported maximum resolution is about 1080i also considered standard and this component cabling will allow for progressive and interlaced scanning of images that come from the signal.
Rgb cable, quite a useful invention isn’t it ?
