Tri Level Sync
An analog sync reference signal that is used in High Definition systems. Tri Level Sync is constructed
with three signal levels, the sync pulses extend above and below a mid-level average voltage (the
blanking level). Unlike conventional analog sync which is bi-level, the proper 50% pickoff point is
already identified in Tri Level Sync. This contributes to lower jitter in digital systems.
YUV
Strictly speaking, YUV does not apply to component video. The letters refer to the Luminance (Y), and
the U and V encoding axes using in the PAL composite system. Since the U axis is very close to the B-Y
axis, and the V axis is very close to the R-Y axis, YUV is often used as a sort of shorthand for the more
long-winded “Y/R-Y/B-Y”.
Y/Cr/Cb
In digital component video, the luminance component is Y, and the two color difference signals are Cr
(R-Y) and Cb (B-Y).
Y/Pr/Pb
In analog component video, the image is carried in three components. The luminance is Y, the R-Y
color difference signal is Pr, and the B-Y color difference signal is Pb.
