Notes
1.
YUV input is an Y,
(B
Y) and
(R
Y) input with the
specification:
a) Y = 1.43 V (p-p); U = 1.33 V (p-p);
V = 1.05 V (p-p).
b) These signal amplitudes are based on a colour bar
signal with 75 % saturation.
YPbPr input with the specification:
a) Y = 1.0 V (p-p); Pb = 0.7 V (p-p); Pr = 0.7 V (p-p).
b) These signal amplitudes are based on a colour bar
signal with 100 % saturation.
RGB input with the specification:
a) R = 0.7
