Component video signal
Component video signal is sent with independent luminance and color signals. It g
iv
es a higher imag
e quality than or
dinary
composite video signal because it bypasses mixing and separating circuits. Component video signal consists of three lines,
the luminance signal (Y) and tw
o color dif
ference signals
(P
B
/C
B
, P
R
/C
R
).
S video signal
S stands f
or Se
par
ate
.
This signal is sent with se
parated
luminance (Y) and color (C) signals. Use a 4-pin mini DIN connector and cable for connection.
Composite video signal
This is the most common type of video signal.
The luminance
signal and color signal are sent combined in one line. Mixing and separating processes are necessary on both the send and recei
v
e sides.
A pin cab
le is used f
or connection.
RGB signal
An RGB signal transmits color information by using a numeric representation of the primary colors of red, green and blue se
parately
.
When the signal is recei
v
ed,
it can be e
xpressed in
v
ar
ious colors b
y
adding and mixing color
s.
This type of signal
is widel
y used f
or sending and recei
ving color ima

computers. Horiz
ontal and v
ertical sync signals ar
e also
necessary
.

used to def

•
A v

position and focus of the projected image on the screen.
Interlace
The most common type of scanning in use in tele
visions. It
