You could down convert HDMI to S-Video.  But I wonder if you could break out the S-video to just one of its coaxial components and use an HDMI over coax device.  Understanding that half of a S-video cable is not the same thing as RG-6, RG-59 or RG-11.  I wonder if it's worth a shot, depending on how mission critical the intended use is.

It sounds like you have a pre-installed cable you're trying to use.
If not, The HDMI fiber cables can do your run no problem.
Relatively inexpensive.  No converters required (built into the cables).
Ebay shows 100ft from $75 to $130.

I just found this (just posted) video directly addressing your problem.
Worth the watch.

Thanks for all the info. The Muxlab and the Anywire converters look very interesting if not for this project but to keep in mind for a problem solver down the road.

I have and use some the HDMI fiber cables for camera lines the few times a year I do a small video production along with the audio production.

It's definitely going to depend on what type of cable is pulled.  Many install systems using S-video would pull 2 pieces of RG59 and terminate with BNC to Svideo adaptors, as that's easier for the installer to terminate than trying to do custom length S-video cables.

If that's the case, then adaptors like this, or even the cheaper HDMI to SDI adaptors would do the trick.

Now, if it's just elcheapo S-video cable, then it's going to be a crapshoot no matter what you choose.  Different cable has different frequency response characteristics.  Getting more data through a cable not designed for that can be unpredictable at best.  You could set it up and it works, then when time comes to use it, it'll fail spectacularly on you.
