Re: S-Video to Composite

["Keith Doxey <ukha@xxxxxxx>" <ukha@xxxxxxx>]

Exactly the same way if its like the one I got from Maplin.

For S-Video to Composite I put a 470pF and 100 ohms in series from 
Chroma to Luma and the Luma signal then becomes composite.

The same method can be used to feed a composite signal into an S-
Video input but as Dan points out it isnt that simple. To do it 
properly requires filters.

Although the Capacitor/Resistor method will give a colour picture 
into an S-Video input there will be all sorts of patterning or 
softening of the picture and it will be inferior to the original 
Composite signal.

The only justifiable reason for doing passive Composite to S-Video 
conversion is if you only have an S-Video input available and the 
source is composite only.
