CVBS video signal Andrew Gabriel 04-04-05

I want to take a CVBS signal from a DVD player to the other end of
the room, some 20'. What's the max length cable CVBS will run over
(these are phono style connectors, not SCART ones)?
Secondly, I already have an unused 75ohm aerial coax run buried
in the building fabric and emerging in exactly the right places.
Can I route the CVBS signal directly across this? What's the
characteristic impedance of the CVBS phono type cable (I found a
reference saying the SCART version is 75ohms)?

According to: http://www.epanorama.net/links/videoconnector.html

20 feet should be no problem for 75 ohm coax.
But I never tried it myself.

regards,
Johnny.

Thanks for that. I need to buy a few connectors
or adapters before I can check it out.
