Default RGB or HDMI to coaxial converter

Hi there,

I was wondering if there's any kind of adapter/converter able to get an HDMI or RGB signal (hd tv) and output it through a coaxial (RG-6) cable. I want to use the hdmi or RGA signal from my Dish receiver and send it to other HD tv in my house.

Any ideas?

There are existing threads about this. Have you searched and looked around a bit?

Bottom line - buy another Dish receiver instead of trying to convert HDMI or component video + audio to RF and then back again.

Sorry but when I checked the only info I got was about using an RF modulator, which wouldn't work to send HD signal. I might have not used the right keywords on the search maybe.

At any rate, a 2nd receiver would not be an option because 1) I have OTA local channels and 2) I don't want to pay $5 every month.

I checked the slingbox pro but I believe the coaxial output is only Standard Definition.

Thanks anyway for the suggestion.

No, you searched correctly. The only way to do it is to use an RF modulator, and you do lose the HD signal.

If you really need it in another room, you can run component video cables + digital audio cable (that's four cables) or use an HDMI cable (depending on the length, you may need an amplifier).

Default Not an answer

Hi guys. I really need to know the answer to the OP's question. It looks like he only got suggestions to do it another way.

Lets assume:
1. The cable company provides only a HDMI cord out of your wall and no coaxial/anything else.
2. Your 1080P HD TV has a HD tuner but the only input on it is a coaxial!

What can I do and is it possible to still get true HD?

Actual Scenario:
I need Picture in Picture. XBox and DVR Box TV. They apparently only make HD flatscreen TVs where 1 of the sources of the PIP HAS to be a coaxial. My Xbox would go component for source 1 and my DVR Cable box can only do HDMI out if I want HD.

Edit: I know I can get a coaxial out from my DVR box, but it will only be SD. Also, I know I can get a RF modulator for the Xbox and make that the coaxial, and the DVR Box via HDMI, but then my Xbox will be SD...

Please help!

You cannot use coax for HD the way you want to use it.

You can use coax as a method of extending an HD signal a great distance but you have to have a transmitter at one end (HDMI to coax) and a receiver (coax to HDMI).

And as you can see - it is VERY expensive:

RGBHV to BNC (coax) is trivial, well, 5 coaxes, 3 if you do sync on green.

Component to 3x coax is also trivial.

How far is the distance? Are we talking over 100ft?

The guy posted a total of two times over two years ago. I doubt you'll get a response...

Default Coax to HDMI

The only way to do that would be to have a coax to HDMI device, also known as a HDMI over coaxial converter. You would send the HDMI out of your dish box into the converter. Then you would go coax out of the converter into the house wiring. At the other TV end you would also need a coax to HDMI converter that would convert the signal to HDMI for the other TV. You can find out more at www.coaxtohdmi.net

If your TV at the other end has a ATSC tuner there is a company that makes a RF modulator for 720p video. Very expensive though: http://www.zeevee.com/
