Someone I know has just bought a nice big plasma Lookng at the inputs and stuff - what's the difference between RGB and Component. (Not composite ) Also the SCART pinout lists a separate ground for each R,G,B signal. Is it really a different ground?

 

It is a different ground, yes. Component is the best quality way to send a signal. It works becasue there is no inteference, change in signal, which occurs in shared signals.

 

Steve,

Electrically the grounds are connected but are seperate to prevent earth loops and induced
noise from voltage and current transients.
I.E. they terminate at one central point within the equipment.

As for the two types, there are two possibilites that I have come across before....

1) 'RGB' and 'component' are names given to the way the signals are grouped but
are essentially the same electrically but may have different connectors.

2) Components refer to all video signals being seperated. I.E their component/signal form.
Seperate H sync, V sync, Red, Blue, Green carrying pure information etc...
As opposed to ...
Composite sync - H sync and V sync merged - (do not confuse with composite video)
and/or sync signals merged with colour signals.

 

Thanks guys

 

This is quite good:
