RE: Composite Video

["Paul" <p-gale@xxxxxxx>]

Video cabling is all 75 Ohm rather than 50 I believe. 50Ohm coax (RG58) is
used for coax networking IIRC???

Would strongly recommend against doing this - it is a travesty to have a
super display like a plasma driven by composite video - the difference
between (YUV and RGB) cf composite is huge. S-Video is much better than
composite too (although not up to RGB or even better component). I tried it
as the first signal into my new Panasonic Plasma and I was horrified at the
picture I got - and it was a good quality composite signal on a short
length
of video cable. Running over UHF coax is also a bad idea as this is 75ohm
impedance whereas video is 50ohm - which creates an impedance mismatch.

Trust me it would be worth the effort to go for a higher quality solution.

A couple of questions:



Has anyone run their plasma on composite and could comment on the
picture quality?

Can you run a composite feed across normal coax (Thinking retro fit
here.)?



Many thanks
