AS long as I am not mux/demux'ing a signal, and dealing with a single stream A/V (a single source to TV), are you suggesting that I cannot transmit full 1080p plus audio in an ip based system.

I work everyday in a system that transmits over 2.5k feet that transmits (2 1080i a/v streams) (2 480i AV Streams) ( 18mb/s internet connection) and (2 telephone lines) and all done in under 25mb/s data stream.  I know it can be done.  I do it all the time.

If I shorten that length to 10', the limits only go up.  the inherent problem with copper is capacitance, and the shorter the better.  (although, in the system I work, under 600' is a problem.  Signal too hot)

HDMI video signals are not compressed are they? Seems a bit unfair to compare it to a compressed data stream.

No they are not.  I am also talking extreme distances.  But the shorter my length of twisted copper is the faster I can transmit my data stream.  It is not inconceivable to achieve great speeds on a dedicated IP stream between component and TV (think extremely dedicated network).  We are talking the difference between transmitting a HF signal over a thin set of shielded and properly terminated wires, compared to transmitting a pure data stream over cat 5 twisted pair.  In all realism, your blu-ray player is taking, what is naturally a data stream from the disc and converting it to HDMI format (or component) and transmitting it to your Display, which in turn is converting it from HDMI to display format within the display.  What I am actually suggesting, is taking the data stream from the blu-ray, or really any format from now on, and transmitting it straight to the TV via IP, and only doing the conversion once.

With proper cat5 Gigabit is good up to 100 meters.  What I am referring to is approximately 2 meters of properly terminated cat 5, running at speeds over 1 Gb/s which is plenty fast to transmit multiple A/V streams.

Actually, in the not to distant future, I see no wires from component to display for less that 5 meters.  802.11n is capable of 300Mb/s now.  If you could dedicate that, in your "Home Theater" then it would not matter where you placed your components, only the speakers and screen would matter.  Even speakers are going wireless.  It won't be long, and all you will need is a power connection within your house.

No, I was not suggesting that. Of course you know what you are doing. This has gotten a bit off track since my original comments had nothing to do with what you were doing, and I only suggested that I was skeptical about what the other guys are claiming to do. That is still true.

As someone who works in the industry I can tell you that "later this year" is not even close to accurate... quite simply these manufacturers could not implement this until next year at the earliest... and even then, we would be talking about adding 1 or 2 ports alongside HDMI. HDMI is quite simply too standard at this point to replace overnight and will be around for many many years. In addition, this article does not address many technical issues... which obviously would need to be worked out.

If you already have your house wired for cat and would like to convert to HDMI you can do so using hdmi balluns... best price for these would be monoprice im sure.

Thanks for the info. What you are saying about the reality fits more closely to my gut reaction to the original announcement.

And also many thanks for info about the hdmi baluns. I wasn't aware of them. The Intellix versions are powered, spec'd for up to 150 feet, and require two shielded CAT 5/6 cables for transmission of hdmi (I assume uncompressed). I'm sure there are other types and brands.

@ruined...

More good info. You da' man! 

I do have one long HDMI cable (50' or 100' , I forget) that I have not put in use yet. Works mostly ok without boost upon testing, but when plugged into my Oppo HDMI swicth, the built-in signal reshaping makes it solid, as you point out. I've read that some AV receivers have that built into their HDMI inputs as well. Maybe also TVs?
