Altinex is pleased to announce that we are able to send 1080p/60 HDMI signal over any type of wire. And when I say any, I mean any. We called this system “Anywire.”

Their publicity is ahead of their site maintenance, so you can't use their search engine to find the product yet, but it's at [Link: altinex.com].

When I first heard about this, I accused Altinex of being late to deliver their April Fools' product, especially when I could not find the information on the internet. But they say it's real.

Enjoy.

This could be amazing if it actually works.

Brilliant.

I wonder if anyone is working on powerline carrier transmission for HDMI yet. :P

1080p/60Hz up to 300 meters distance on lamp cord?

Until I see this work and work consistently, I call BS. This is like that flaky field terminated HDMI ends, that manufacture marketing were insisting worked so well. Total BS!

I wonder if this works better than the $9 1x2 HDMI splitters we've been using from Amazon?  I cannot figure out why they don't work reliably!

That HDMI splitter looks like it has a better chance of working than this thing a client handed me once. It was a gift from his daughter who knew his new bluray player would not work since his AV receiver only had component video. She had good intentions, and started off looking smart. Needless to say, I humored him, and hooked it up to test it. :)

I believe that is actually meant for a certain pc video card that can be configured to output analog video.

There's no mention of HDCP anywhere, probably means only for use in signage and surveillance, ie: non-protected content only I suspect...

I think you might have an open capacitor in your power supply.

MTE.



My thoughts exactly.



I am, however, grinning at the power amp output type of binding posts they use. (I really did tell the guy from Altinex that I thought this was an April Fools product that they didn't deliver on time!)

The IE 7 power cord is a little suspect IMO. Since when have you seen anything other than cheapo round wall wart power for devices like this?

"A single transmitter is capable of driving up to 4 receivers using either 4 individual wire pairs over 300 m each, or by daisy chaining the receivers"

So if i daisy chain receivers i can transmit a source to 4 receivers using 2 wires of "any" type? You better test this before you spec it for a project lol.

I emailed them and this is the response i got..

"Anywire provides full HDCP and EDID compliance. EDID is propagated from the display back to the transmitter. HDCP keys are exchanged as per HDCP specification."

if this is true they should focus next on cancer research....

There is a nice detail -- The unit supports up to 12AWG NON POLARIZED wire. What is "polarized" wire? Is this what was used to manufacture directional audio cables? Will this device work on knob and tube wire? (A couple days ago I bumped into some that is still in use.)

And this is novel: "A single transmitter is capable of driving up to 4 receivers using either 4 individual wire pairs over 300 m each, or by daisy chaining the receivers. The only restriction being the wire pair from the transmitter to each receiver cannot be bundled together as crosstalk will occur."

I'm not sure how one can avoid some bundling in a practical situation.

Anyway, this whole scheme reminds me of the miracle data compression products that claimed to be able to compress the data on whole hard drives to a few hundred or thousand bytes. There were a few grand press releases, then silence -- probably after their CTO discovered math and computer science.

I like the delayed delivery of an April 1 product hypothesis.

Hi guys. Took a look at their manual and the answer as to how they are doing it pops out:



Two things:
1. There is lossy compression of HDMI to lower bit rate
2. They are using a powerline transceiver (PLC) which obviously works on non-twisted wire.

So it is likely that it would work. Question would be at what level of fidelity.
