The red,green,blue video signals each have different dutycycle on/off times to produce different FREQUENCYs at DC voltages right?
it seems that the RED signal has a dutycycle on/off timing to have a frequency at Xhz, at a DC voltage is this right?
The blue video signal has a dutycycle on/off time to have a frequency at Xhz at a DC voltage is this right?
The green video signal has a dutycycle on/off time to have frequency of Xhz at a DC voltage is this right?

RGB video and component video signals are not simply DC voltages. All the signals carry interesting waveforms
Then if they aren't DC voltages what are they please explain more ? cause its seem like RGB video and component video signals are OTHER than DC and AC voltage but i don't know what to call them or relate them too

""In general, set your oscilloscope to trigger on the sync pulses at the bottom of the composite waveform, or at the bottom of the RGB video's green waveform, or at the bottom of the component video's Y signal, or on one of VGA's sync signals. Then use your scope's other channels to view the other signals. Triggering on the analog sync tip may be difficult if your scope doesn't have a TV Trigger button""
Wait i don't understand or make it more clear please
I set my oscilloscope on TV triggering when measuring composite,RGB,VGA right?
1.) The problem i don't get is how do you SEPERATE the sync pulses,verical and horizonal pulses to go to "channel#1 on the oscilloscope"?
2.) Because composite mixes the sync,verical and horizontal signals into the Red,green,blue signals you can not seperate them, so how can i seperate them then?
3.) I would have to put my oscilloscope on DUAL MODE too , to see 2 channels at once right?
4.) Once i have seperated the sync,hortizonal,vertical on channel#1 how can i make the oscilloscope trigger the BOTTOM of the pulse and not the "top"?

How do you set the oscilloscope for for negative-going trigger?
I still don't know how to seperate the triggering on channel#1 and the composite or RGB on channel#2
example
RGB has 3 wires ,
i put the "Green wire" on channel#1 on the oscilloscope and set the oscilloscope to negative-going triggering right? but how?
Then i put the "Green wire" on channel#2 to see the color information or green channel voltage and set it to TV triggering?
