RGB Component

This way of transmission separates the red, blue and green information. each colour signal will travel down individual cables and will contain that colour information with luminance as well. there will be in most cases a fourth cable containing the sync information which is known as RGBs. Other versions include RGBHV which has five cables and contains red, blue, green, horizonal and vertical sync. agian just as with composite the amplitude of all three signals are one volt peak to peak.
Another transmission method that seperates the signal is YUV. this signal is also known as Y' R'-Y' B'-Y' where the Y contains green and luminace while the blue and red information minus the luminace so overall uses less information as R'G'B'. so with the PAL signal being clocked at 270Mhz the rates at which each colour signal will be equal at 90MHz each.
The signal gets created at the start where the video camera caotures the light and splits into three primary colours. Now depending on the luminance of the colour of the pixel it will be sampled as a voltage that can be read later on in conversion.

RGB component are used in various ways such as,

• Scart
• Phono
• DVI
• VGA

These are just a few of the universal connectors widely used in the world.

Phono is easily noticed by there red green and blue cases around the connectors as above. These will enter the red green and blue video in/output on the machine.
Scart is another easy one with the universal plug going male-male as above.
VGA is a 15 Dtype connector but can carry HD signals down if transmitter and receiver intructs it to.
DVI is different as uses less of the pins required to send/receive RGB SD.

DVI-A only allows analogue video through so will not work with DVI-D (dual/single link).
