NO.
Component is TOTALLY different to RGB
A
TV
(or any other LCD/CRT etc) displays 3 signals RED GREEN
and
BLUE. These contain the information that makes up the picture,
additionally the TV requires 2 timing signals - Horizontal and
Vertical
syncronisation pulses to define when each line or frame of the picture
starts.
It
is how these make it to the display that ultimately decides how good or bad
the picture is.
Starting witht he best and working down the list, here are the
definitions and how many cables are required
RGBHV 5 cables
A
PC outputs RGBHV from its VGA connector (I wont mention any digital formats
as that is not relevant to this topic). That is the PUREST form of
ANALOGUE video you will find as each of the 5 signals is transfered
discretely.
RGBS aka RGB 4 cables
Discrete colour signals but a COMPOSITE SYNC (S) signal containing
H&V pulses. Many items of domestic video equipment that claim to output
RGB actually output RGB+CompositeVideo rather than RGB+CompositeSync. For a
TV this is no problem but some monitors can get upset if they expect true
sync pulses.
RGsB aka SyncOnGreen or SoG 3
cables
As RGBS except that instead of a separate Sync signal is sent on the
GREEN colour signal just like Composite Video
Component Video aka Y-Cr-Cb 3
cables
A black and white composite video signal containing Luminance
LUMA (Y) Brightness information and composite sync. Cr and Cb are two
signals containing matrixed colour information to extrace the Red/Blue from
the picture information in the Y signal. One the red and blue is removed
the
only information left is green.
S-Video aka Y-C 2 cables
A black and white composite video signal containing Luminance
LUMA (Y) Brightness information and composite sync. CHROMA (C)
contains ALL the colour
information.
Composite Video 1
cable
Almost the lowest of the low.
Contains
all information for RGB and HV.
RF can have many
signals on 1 cable
The lowest of the low. Composite
Video
and usually Audio as well, modulated to a much higher frequency but can
enable multiple signals to be distributed over the same cable by choosing
different carrier frequencies

On a similar
off topic :)
My amp switches component video as well as
svideo.
My tv has 2 rgb
scarts which are both used.
Is it possible to
route signals from the component video outlets on the
amp, into an
RGB-enabled scart socket on the TV? I haven't managed to
find a
cable (online) that will do component video --> RGB scart.
Any
ideas?
Thanks
