Hello
has someone ever tried to send an SPDIF output threw a wireless video transmitter for home use ? It appears to be working....
THX in advance

I did try it with a standard wireless for home use and it works fine!
Audio Device (1) S/PDIF OUT -> Wireless Video Transmitter VIDEO IN -> Reciever VIDEO OUT -> S/PDIF IN Audio Device (2)
Even 96 kHz S/PDIF! Not bad for about 50$.
Enjoy if you need

Thanks for the note bizangoin. I've heard that this would work, good to have a data point that it does. And I suppose you could use multiple receivers around the house too...
what wireless adapter are you using? just curious...
Peace
I have used a THOMSON VS470 Wireless device. It is a very common model.
That's actually very cool indeed. Thanks for sharing, this idea would never have occurred to me!
(and to think that a few years ago I worried about the limited bandwidth of coax cable possibly harming spdif connections....)
Thanks bizangoin for sharing your experiences.
I also thought about how to transfer wirelessly an SPDIF audio signal.
I've read this Video transmitter thing other sites too.
Does anybody else found any little device which can do this task?
I wonder how these wireless video sender sends the signal which is connected to it's Video input. Does it transmits the SPDIF digital audio totally transparently, bit-perfect?
BTW I have "Logitech Wireless Music System for PC", this is good, but it transmits only analog sound.
I also have the Logitech (Slimdevices) Squeezebox and Roku Soundbridge too, but I thought I'd connect the SPDIF outout of the PC too.

Really? A transmitter like this couldn't make good quality analogue possible. In the docs I read it's using Bluetooth protocol.

Hi
I'm correcting myself. It indeed using Blutooth, and it's transmits the sound digitally. It's basically an USB soundcard, transmits the signal digitally, and at the receiving end it just contains a D/A converter, and gives out an analog sound, that's it. It would be perfect if it could contain the SPDIF out also.
Marmitek has a nice solution to wirelessly send SPDIF. The Audio Anywhere 685:

You can use both coaxial and TOSLINK together.
So for example Coax at the transmitter and TOSLINK at the receiver.

I also have (although I don't use it any more) a Logitech wireless music sender (Bluetooth) and if the receiving unit had a digital output, that'd have been be very neat indeed. Nice, useable piece of kit with a decent range, anyway, although re-pairing the connection was a bit of a nuisance.
Did you guys notice that the last post was almost 7 years old?
Topic is interesting though. I'm wondering why it works, and if you can transmit encoded Dolby or DTS streams. I remember I had some success with an Airport Express in transmitting DTS WAV but that's very cumbersome, and was getting stutters. Not that I need to do it nowadays though.
Oh god yes!! I love a solution for transmitting 5.1 audio digitally like that.
I know this is an old thread.
Did anyone else try this out? Will this work with any kind of wireless video transmitter which is able to send composite video using simple modulation? Does S/PDIF have any kind of error checking to know if data is arrived bit perfectly?
Mod: Just saw that even dirty cheap car backup camera transmitters should work: https://www.youtube.com/watch?v=jB529QdaZm8 Mind=blown. I should try this out.
SPDIF requires a 32 bit word for each channel. There is a pre-amble and a couple of status bits including a parity bit.
Due to this parity bit error detection is possible.
SPDIF is a unidirectional real-time protocol.
If the receiver detects an error in cannot ask the sender for a retry because it is unidirectional.
Even if this would be possible, the retry is of no use as the new sample will arrive to late (real-time).
But I assume if the receiver detects errors it can replace them with silence instead of playing garbage. Is that right?
Don’t know.
Bit errors are rare.
If they are massive, you hear a lot of static from your speakers and run for the volume control :)
