Even lossy compression, I don't see how it could work technically given the transfer methods allowed.
BUT! The diagram you showed does make me think of one way they could be doing it.
It is very inexpensive to convert that HDMI into a 480i analog composite video signal. Send that as a balanced line a great distance. Then cheaply upscale it back to a 1080p digital HDMI signal.

That is a VERY dirty thing to do. It would look like crap. But it would work. And seeing what look like transformers on the output stages, is a strong indication that might be exactly what they are doing.

It sounds like a couple guys are willing to try this out and prove it wrong. Anxiously awaiting your review ;)

The transformers are there because the silicon they are using is made for powerline networking. So in that sense, this is a power line networking link and an HDMI compressor. If you can sustain 10 to 20 mbit/sec, you can still push 1080p through. That is what online streaming sites do (often running at even lower bit rates). They could also downscale but I don't think they need to go down to 480i/p.

I don't know, 10-20 mbit/sec might still be pushing it on lamp cord at that distance.

Chris, you buy a set and send it to me, I'll test the crap out of it. Pretty sure I have a 1000ft spool of 16ga zip speaker wire on the shelf.

No one has said yet, what is the price on these things? I'm going to go Google a little.

Nope: Can't find it for sale anywhere. Maybe not out yet? Vaporware?

This is what I thought... It had to be PLC. I don't see why it wouldn't work....

The wonderful Fred Harding reviewed this puppy ... and he was mightily impressed! [Link: cepro.com]

I'm at my wits end with HDbaseT ... Im willing to give this thing a try...

"Directional audio cables" are actually directional from a point of view of performance. A hot and a ground, usually mildly twisted, go from one end to the other. The shield, however, is only connected at one end. This end is called the sending end and the directional arrow goes away from there.

These cables perform better in that direction than in the other since noise picked up on the shield is drained to the source end rather than to the ground of the following stage. After I laughed at these cables for a few years (mostly because monster never explained how they were made), I realized I had seen cables wired this was when I was a stockboy at Ryder Sound in the late sixties. All their patch panel cables were made with the shield connected at the source end.


Me, too. The hots and neutrals were generally about eight inches apart. Ceramic tubes insulated the wires where they passed through wood. This wiring would have much lower capacitance from wire to wire than any paired wire, but horrible interference rejection. This device might just work over knob and tube!

200mbps... over any kind of wire at that those distances... and it works??? Ok, I'm impressed!

Still, 200mbps means a lot of compression - not a little. Fred's used to watching his old BETA tapes, he wouldn't notice the picture quality LOL :)

That being said, when there is no other way to get appropriate wiring to a TV and wireless products fail to work, this could be a Hail Mary to get the customer a working picture on a TV.

MSRP of $750 for the set. Pricey but impressive feature.

Brad, I was just about to order you one but it looks like 3PedalMINI is willing to be the Guinea pig.

Have you found a place that is selling them yet? When I searched awhile back, I couldn't find anyone selling it. Let alone any of my distributors.

Curious what my cost will be. Don't know if the MSRP is like an Ethereal MSRP or a Atlona MSRP.

Nah I gave up...just assumed it was either vaporware or a poorly timed April fools joke.

Besides, we don't want this to work, do we? It'll put Brent out of a job lol

Don't know who is marketing it.

This is an interesting product, we looked at this (HDMI over PLC) 4 or 5 years ago, it even had the option of running over 110V. At that time our testing did not make us happy and we went in other directions (re: M3B).
But this is non the less cool and is worth (at the least) thinking about.
As to losing my job, do not tease me (I am old and sensitive).

Yes, I know. The shield/drain scheme with the shield terminated at only one end, avoids ground currents circulating in the shield. It's a standard technique mis-characterised and mystified by the audiophiles. When I first heard the term "polarity" I could not imagine what they meant. Finally, I got my hands on a cable and discovered their innovation -- that I had also discovered while reading in my teens.
