Wirelesss Transmission of 48k Digital Audio

[fmak]

Is there a way of transmitting high quality audio (from a satellite receiver) from one room to another without wires. Distance is only about 15m but there is no way of hiding cables.

I don't want to use a wireless computer network if I can avoid it. May be some form of old fashion FM transmitter?

you could run data over the power wiring in the building, but that will probably create as much noise as just using wifi.

As strange as it sounds, you could try one of those 2.4ghz wireless video transmitters you see at radio shack, walmart and other places.

Those can handle several MHz of composite video bandwidth and they're 75 ohm input, and coaxial SPDIF and composite video aren't that far apart in signal amplitude. And I don't think they actually do any manipulation or decoding of NTSC - rather just modulate the straight composite signal to 2.4ghz and then demodulate it at the receiver. Which makes me think that they might pass a NRZ encoded SPDIF signal.

Head to walmart and give it a go. Worst case, it doesn't work and you bring the thing back.

(don't anyone dare say anything about jitter)

RadioShack sells for 20$ an ethernet-over-power-line bridge. If nothing else, you might be able to wire an adapter; if I'm not mistaken, even cheap Cat3 (10mbps ethernet) cable is rated to 100mhz. Ethernet jacks are about 25 cents a piece, and you'd only be using two of the wires. (Ground and one of the data lines.)
