The reason why RGBHV is the best signal you can get applies to all types of
video signals.

RF = Combines all audio, video, and sync all in one conductor (worst type of
signal, very vulnerable to interference)
COMPOSITE = Contain red, green, and blue plus sync in one conductor. (still
very low quality image)
SVIDEO = Luminance and Chroma separated by two conductors. Still the same
amount of lines as composite, but better color and hue saturation. (This is
where separating different signals will begin to show improvement)
COMPONENT (G, R-Y, B-Y / YUV/ RGsB) This separates red, green, and blue
signals, but carries the sync signal *usually* with the green signal. Best
possible NTSC image, allows for progressive scan. TYhis is the nicest you
will see on most "TVS" today.
RGBh/v & RGBHV = This separates all the colors and sync signals over 4 or
more commonly 5 conductors. Best quality image, can send resolutions all the
way up and beyond 2000x2000. (you will see this input as either 5 BNC
connectors or a 15pin VGA input. There is no quality difference between VGA
and RGBHV, VGA just send extra information along for the display device)

(all the digital signals vary due to A/D D/A converters, etc, etc)

As you can see, by separating different signals, you can improve the quality
of the image. Now ALL type of signals are susceptible to interference from
other sources, but depending on quality of cable and many other factors,
interference can be avoided.

What makes RGBHV superior to the difference signal configurations? Seems
like the difference signals would be more immune to corrupting the
luminance.

You are somewhat correct, but misinformed about your component video
signals
and how they are refered to. A component signal consist of Red, Green,
and
blue signals, Usually with the sync sent with the green signal.
Component
signals are corresponed by Y, R-Y, B-Yor RGsB. You stated all colors as
"-Y"."-Y" means minus lumanince signal. Without the luminance, you
wouldn't
see anything.

Also, the best signal to send to an analog TV set would be RGBHV (Red,
Green, Blue, H-sync, and V-sync)

RED

When you say "coax" (not coaxil), do you mean baseband video, or RF.
RF
is
what you get with cable TV.

If you were to convert the S-Video to RF, or to baseband, there would
be
no
point to have S-Video. Therefore it is a waste of time to convert it
down.
The next best standard is with R-Y, B-Y, and G-Y. The very high end
sets
have this. Your DVD player would also have to comply to that standard
as
well.

RF is the lowest in quality, then there is baseband video with
separate
L
and R audio. The next step up is S-Video with L and R audio. The
next
step
up is component video (as mentioned above), with separate L and R
audio.
The very best is what the broadcasters use in their production
facilities.
This is full bandwidth digital video.

If you want to enjoy your TV viewing experience, you will have to
invest
in
a good set.

I have a DVD player that has S-video and composite video out. My TV
only accepts coaxil. I know S-video is better than composite. Can
S-video be converted or an adapter be put inline to match to coaxil?
My Amp accepts composite video in.
Any schematics or diagrams welcomed.
Thanks
