SOG: sync on green, when we should use?
it always a question to me. A saying is the SOG is used mainly in the
Graphic (computer),and also , in the color diff input(
component input) , also the SOG is used to reduce the bandwith of the processor.
The composite sync information is integrated in the R G B's G line, and the system then need to sperated the composite sync (H,V sync)to the H sync and V sync to use.
