RG6 Coax to RGB possible?

Hi guys,

I have a DirectTV receiver setup in my garage that sends the AV feed
via RG6 coax cables that were prewired when the house was built to all
the rooms in the house. Now I bought a projector, Optoma DV10, which
only has the following inputs: RGB, S-Video, composite video, component
video, HDTV compatible.

Basically, my problem is connecting the AV signal from my coax wall
outlet to my projector, which does not have any coax input. What do I
need to connect from the coax wall outlet to the projector to get both
video and audio?

I am surprised that there are no modulators on the market that do this
type of conversion. I think RadioShack has an RF modulator that takes
RGB to coax, but I need the other way around. I know that I can
probably do wireless from the receiver to the projector, but I have too
much interference.

Thanks in advance for any help.

You don't need a modulator, you need a tuner. If you have the space, a
VCR will do the trick.

Gary,

If your DirecTV feed to the other TVs in the house is an RF output on
channel 3/4, then you can demodulate this RF signal using an RF demodulator
and drive the projector's 'composite video' input. We can offer specific
demodulator suggestions if you wish.

If your DirecTV feed is a composite video output (which I doubt since this
only contains video and no audio), then you can directly connect it to the
projector's composite video input.

If you wish to project HD material from DirecTV, a single RG6 coax will not
suffice. You will need 3 separate component cables from the satellite
receiver to the projector.

Bert,

I cannot believe I did not think of that.
That really is a great solution for me.
Thanks.

Smarty,

You are correct in your first paragraph.
What type of demodulator suggestions do you have?
Thanks for the reply.

Just realize that unless your DTV receiver is different from most
such devices, the audio carried on the RF signal will be monophonic.

Gary,

Bert's solution will work fine since you can convert the DirectTV output on
channel 3/4 into composite video and audio outputs using the VCR as a
demodulator.The units I was thinking of are like the one at:

Radio Shack used to sell a similar device for $39 but I don't find it on
their web site currently.

You are likely to give up the stereo audio, as Bert indicated, but you will
also give up the video quality which DirectTV can deliver by using this
method. In particular, HDTV programming will not preserve the HD resolution
if sent as an NTSC RF signal on channel 3/4 as you are currently doing to
other TVs in your home. This may or may not be an issue for you.
