Say someone had their coach wired for regular old COAX for TVs in the kitchen and bedroom but installed a Sat dish with converter. These DISH or DirectTV boxes have an HDMI out and a S Video and 2 Audio RCA adapter outputs. The HDMI works fine for a single TV and splitter adapters are available. Perhaps they have a 39' stretch (or SOB O) )and didn't want to run a HDMI cable under the coach and all that. Is there a simple way to get from the Sat box to Coax?
I've been searching the interpipes and haven't found anything but I know Johnny Bridges and others know this electronic TV kind of stuff.

Kerry,

if your reasoning for Coax is the cabling and not the final output
device, check for HDMI Coax Extender

The yellow jack/plug is for composite video, which is the lowest quality.
Next up in quality is S-Video.
Then Component Video (Red/Green/Blue).
Then HDMI.
Audio is always Red and White with the first three above. Red is for right channel.
Coax cable is for the RF signal off the air, cable box, satellite, or converter.

When you say "S-video" do you mean the little multi-pin connector or the yellow RCA connector?
I needed to do go from yellow/red/white AV to channel 3 or 4 (selectable) and used an old timey VCR.

Like I said., if what he is calling "S-video" is actually composite video, a plain old VCR is capable of doing what he wants. But I haven't seen a VCR with actual s-video in/outputs. If the video plug is not a yellow RCA, I have seen on the web ways to convert s-video to composite by grafting the ends of the cables together. I don't know if it works.

Last time I messed with s-video was late '90s or early turn of the century. Those brain cells atrophied a while ago, so I can't remember if I was converting something TO s-video or something FROM s-video.

Marmitek offers some devices that might work together to provide stuff
you want.
First: HDMI -> SCART => Marmitek Connect HA13
This converts your HDMI source to SCART
2nd: SCART onto Coax for around the "house" -> Marmitek MegaView 70
Transfers SCART input onto coax cable (Unfortunately PAL only not NTSC).
Alternatively, for the US market
RCA Compact RF Modulator (CRF907R)
Maybe some of that is of help.

Well there is one lower tier way than even yellow video out--- RF ch 3/4. You could get a modulator to run RF down the coax to get video and audio to the distant TV. It depends on the TV size and capability as to whether the RF ch 3 format would be bothersome to you. If it's a small LED or old CRT it will do what you are asking it to in your first inquiry.
