100W ?
PoE+ is about 25, some non standard systems that use all wires are 50 but 100 without using dangerous voltage levels?
So when do the special super-duper $200 6' cat6 monster cables come out?
HDMI cables used to connect a multitude of every day home audio and video devices may become a thing of the past if a new standard by the HDBaseT Alliance catches on. "HDBaseT technology is poised to become the unrivaled next-generation home networking transport to meet the ever-changing trends in the digital media market," …
I designed a PoE system for a major Japanese supplier which put over 100W down the cable, using 3 of the 4 pairs, the other pair was audio data.
All the voltages were ELV safe (i.e. touchable) and the current density was within NASA's safety limits.
It dissipated about one Watt per metre in the cable at full load, that's the problem, there's hardly any copper in CAT5 cable.
Getting all this and Gbit data will be a trickier prospect though. It would be most useful if they do it. Best of luck to them.
Didn't they do this originally. Look HDMI cables are nice and all that, but why not have nice easy RJ45 (8 pin modular) connectors in the first place. It would have saved EVERYONE lots of grief with expensive connectors and difficult to place terminations.
Actually a better system might be to have a SINGLE coax corrector for the video for this hi-def stuff (junk). Much easier to handle, just like the NTSC/PAL connector that was usually yellow and paired with left and right audio.
I also have a 10m HDMI cable. I think it was the cheapest one I could find, and was from somewhere like Dabs. It just works. No problem, even at 1080p.
However I had problems with stupid BlueRay playback and messages (in 1080p) telling me that I wasn't priviledged enough to watch the BlueRay film I stupidly paid for!! (It actually turns out I was priviledged enough, I just needed some software on my laptop to read the disk directly, and re-create the video without the stupid messages!)
It will be very useful only in business environments without the need to buy multiple HDMI->Ethernet switchers/converters although for years still converting will be needed to attach current HDMI ports equipped hardware until the new HDBaseT ports will be included too.
@Christian Berger: you should use a properly shielded HDMI cable certified for 1.3a or 1.3b. I have a 12meters 1.3b Atlona HDMI flat cable for my 1080p Sony projector and it works flawlessly, no repeaters needed, no dropouts, HDCP is working smoothly with no disconnections.
I always called 1024x768 1024 res, 800x600 800 res, 640x480 640 res etc (as did my friends)
When I first saw 1080p I assumed it would be ITRO 1080x800, but no, "they" count the lines as more important. Therefore this 2Kx4K is probably right for "them", and will likely become known as something like "2Ki"
Stupid, useless fecking connection standard
This is nowt more than some big players trying to get licensing rights on something so they make more money. They get this in then everyone else has to start paying them a license fee to put the new ports on the back of their products and we'll all need to go out and buy new tv's, blu-ray players, consoles etc as our old uns will be incompatible.
Then, just as we get used to the new standard, having spent a fortune getting the new kit some other consortium will come up with something else and the process will start again.

So this is going to carry HDMI (which may be up to 10Gbit/s - they reckon they can scale to 20Gbit/s), plus Gbit network, plus 100W of power... all over a cat5e cable? Huh; a 2 foot long one, maybe. If you're lucky. This might work for short distance interconnects (eg devices in a media center), but I just can't see this working for any distance. Cat6a requires all 8 cables just to push 10Gbit. Umm.
Where is the need to send 21.6Gbps of video long distances? Not even in 10 years will there be a consumer device that can source that much REAL data. It makes more sense to send the video in its original storage format, which will remain 5 to 100Mbps for quite some time, and decompress to high bitrate pixels at the point of display.
100W over Cat 6 - It would take about 45V @ 1.2A on each of the four pairs to survive 100m. Fire icon, because thats what would happen if you had a coil of extra HDBaseT behind your TV.
Why would the power need to go toward the highest power drain device in the network. Why not have the TV plugged into a power and HDBaseT and let the 100W originate at the TV then it can power the BluRay / Media Centre / other low power device. Really if your writing is earning you a living you ought to be able to figure out things like this.
One look at the major players, Samsung TV/BluRay maker, Sony TV/BluRay/PS3 maker, tells me this is going to happen. Other manufacturers already pay a premium for HDMI if the premium is the same for HDBaseT then we have a winner. Even if the premium is a little higher consumers will mop it up because the cables are so cheap. If you think this is not going to become the next standard your a nuttier than squirrel shit.
