placed first in the system. Since the blue color difference channel (P'
B
) is next and the red color difference
channel (P'
R
) is last, then it also makes logical sense to place the B' signal on the second channel and the R'
signal on the third channel respectfully. Thus hardware compatibility is better achieved when using G'B'R' rather
than R'G'B'. Note that for many G'B'R' systems sync is embeded on all three channels, but may not always be
the case in all systems.

Due to the high frequency content of the video signal, it is recommended, but not required, to add a 0.01-
μ
F capacitor
in parallel with these large capacitors.
