Do they generate a coax cable near an s video on the other running out?
Answers:
I estimate they're different signals and you'd need some sort of converter?

No. Co-ax only have two wires (the main core and the braided one). S-video requires four wires. You would need to use some type of converter to tuning the signal from the coax over to an S-video signal.
