video signal applied thru coaxial cable.
It can be removed in case of high impedance video generator.

R1 and R2 are to reduce video modulation depth from typical value
(for example R1=1K
and R2=10K
reduce VMD by about 8%)
Cx is dependant on the crystal characteristics (Cx=27pF on Motorola application Board)
R2**

C1 value depends on standard: 470pF is for 50

and 750pF is for 75
