Hi All,
A friend and I were just shooting the bull about coaxial digital connections and I was wondering if anyone had ever heard of someone sending digital audio through a transceiver. Our example was my HTPC. We were wondering if there was enough bandwidth through a basic audio sender/ reciever to cover a digital coaxial signal. In our case the HTPC would be behind the couch and the have the PJ next to it. The problem is the audio, which would have to make a 32 foot route to get to the back of the Stereo, including a 6 foor journey across the open floor.

Just wondering if anyone has either done, or heard of this being done....

Personally havnt heard of it.

The bandwidth in a common RCA/Coaxial cable is enough to handle a digital audio 5.1/6.1 signal. However, when transmitting wirelessly it may interfere with clean digital reception on the other end. Its possible that you could hear alot of skipping/blurping audio.

I cant say with any exact experience, but when you transmit a wireless audio signal sometimes there can be dips/losses in signal that is hard to hear or even notice. If the digital signal is lost, you WILL notice. Give it a try.

Anyone know the maximum length an RCA cable can go before digital degradation starts? Might just skip wireless and go with a very long cable...

I would go to RadioShack or a local store and pick up 2 of these.

And 25-50 feet of standard coax cable. If you have access to a crimper you can make a custom length cable, or its an excuse to buy more tools.

The maximum length for SP-DIF (digital RCA coax) is 10-15m with high quality 75ohm cable (about 30-50 feet). It might be pushing it a bit, but you should be able to make it in one cable. You could always use a signal booster if needed.

What about sending it optically?

You probably would not be able to send the digital signal directly through a basic wireless analog audio sender anyway. You would need modems in between the sender/receiver and the digital equipment. I wonder if anyone is making those wireless extenders for digital audio signals.

I have never been able to find TOS-LINK cables more then 6' long. If anyone knows of a source, that would be great, I need 20 feet to hook my iMac into my stereo.

The only thing I've seen that might have the capability is the RemoteTV from Belkin.

I'm pretty sure that this would have the bandwidth, but it would be kind of overkill, I think.
Little expensive, too... just saw that. $499 price tag. But at least it says that it has no
problem sending SDTV signals (DVD quality for those who don't know), and has a 48Mbps
bandwidth.

Wonder if they'll ever make an HD one... wonder how much it would cost.

25' for ~$8 ... check it out at monoprice.com ... quality is excellent as well...

cheers,

Another good way to move RCA digital signal is through RG6 cables with RCA adapters on each end. Since they are shielded they can take a bit of abuse and they are easily trimmed and routed.

*jaw drops* Wow! Long optical cables! World domination is MINE!
*reels herself back from the deep end* Thanks for the link, that should be helpful.
