S-Video, composite, coaxil video in Question

G

George

Guest
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

If your TV only has a coax input, you will need to buy an RF modulator. This
converts the video & audio output signals in an RF signal. You can pick up
an RF modulator a radio Shack, Best Buy, Circuit City. They run around $30.
 
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.

If the TV only has an RF coaxial (antenna/cable TV) jack then it won't make
any difference, Svideo is separate chroma and luminance lines, composite
(RCA jack) is just the two of those combined, the RF input is those combined
with audio as well on a carrier frequency, and if your TV lacks an Svideo
jack then it's not capable of making use of the improved picture quality
anyway. Buy an RF modulator and you'll be good to go, even Radio Shack can
set you up, the other option is buy a quality TV that has an Svideo jack.
 
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)

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

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.

I don't see that at all. Of course, what you said is nearly always correct.
Sometimes, however, there are cases where using composite can be superior to
s-video in consumer applications where the a comb filter is inferior to the
display or destination comb filter. All else being equal, you are correct.
There is sometimes more to the story. For instance, some cable boxes have
really cheap comb filters to get an s-video connection, while many high end
televisions have much better filters and you get a better result by using
the composite output.

I was under the impression that the trend toward sending difference signals
and Y was because RGBHV requires much wider bandwidth due to the duplication
of the Y component. Also, the separation of the sync has no great
advantage, but does increase the probability of bad connections, having 5
lines instead of 3. Since most video is recorded, encoded, and supplied
with Y, R-Y, B-Y, transcoding to RGBHV introduces another step of processing
that would potentially degrade the signal. Finally, duplicating the Y in
all three R, G, & B leaves the possibility of corrupting the Y component.
Thus, in any application in which the source is not directly connected to
the display, there are significant advantages to using color difference
signals compared to "pure" component RGBHV and no great advantages to the
latter. Again, there is sometimes more to the story.

YOU ARE VERY CORRECT. Components can make or break ANY signal. A/D D/A
convertors really mess stuff up. Cable length, comb filters, and much more.
Some output devices do not output actual svdideo at all, but just send
composite over that connection. As I could go on FOREVER about different
factors (ie bandwith, conductor size, etc) I won't.

Have a nice day
