HDBase-T: So if this comes through as a major player, would this mean that GPUs and NICs would combine? Would HDBase-T look into replacing DVI and HDMI (and even DisplayPort) for GPUs? In theory couldnt this make cabling much simpler? Power cable for the computer, monitor could run PoE (if 100W is actual) and then the common mouse and keyboard USB connections. 

I'm not sure if im just not fully understanding this or that this could really change things in the market. It seems like something big, yet its gotten little press.

Yes, it really is a game changer. think about wiring your house up with one server machine, and then having a bunch of essentially dumb client boxes, and hooking them together with Enet for video distrobution. a faster, cleaner signal than old coaxial. And imagine never having to dink around with a limited length VGA HDMI or DVI cable with its relatively thick and inflexible cabling again. and unlike lightpeak or USB.3, cat 5e and cat6 cabling, jacks, and tools is pretty ubiquitous in the western world, so the implimentation curve should be fairly small.

that is a really cool idea :)  it reminds me of my thoughts about USB when it first came out. In a way it's been making versions of itself 'universal' to alot of devices (hdmi as well as chargers for devices) simply plug it in, even if it takes a special shape. Though with HDBase-T as long as they don't change the RJ-45 into something else, it'll be a very clean world for the wiring of those like you talked about.

and with the IR transmission included, wouldnt this allow electronics to be put in any area? Like I could have my desktop away from my other heated electronics and not be limited to the DVI cable length? 

But then again how would costs be to move to this? will routers include this? 

Probably my biggest question is what networking companies will get behind this? Cisco, Trendnet, D-Link, any of the major player (those are the only 3 that come to mind quickly)

I would think that if this was the next coming for such interfaces that all the major players would get involved. Heck, some might be doing R&D at the moment for when it's closer to a reality of deployment.  Though as with anything new, it'll be pricey at first until it's adopted more, even though this seems like a fairly simple thing to me, that is how these usually go.

HDBaseT - haha.  Did anyone notice how they are going to use straight up ordinary copper Cat5e cable and achieve all those speeds and features?  And Belkin has been pushing $40, $60, $80, $100 printer, USB, video, and HDMI cables as 'superior' cables all these years.

well to be fair, those in the know have known for years that those "cables" were a sham. Hell, I went to a radioshack last month to get an obscure gender-bender, and they had one 3ft USB cable for $20us. for $6.50 per foot, the damned thing should plug itself in!

Yes, I agree with you.  We're on the same track.  A lot of us have known those special cables are nothing special at all.  I just wonder what happens when this standard gets pushed out if they will still highlight that ordinary twisted pair cable is all that is needed.  Will Belkin be given the freedom to lie?

Will someone realize they've been getting the shaft all these years and get a lawyer?

We are using Gefen extender based on HDBaseT technology.

 It's really doing that - HDMI 3D + ethernet+IR+CEC over single  CAT5 cable up to 100m.

You asking - why hdmi cable so expensive and transfer only for 10m? - the answer - secret is  in modulation. PAM modulation uses few voltage levels for transmit bit. So in one period of time you can transfer up to 2x 5 bit (lets say triggering is on rising edge) in comparison with HDMI/USB in one period you transfer only 2x 1bit . So as a result you can send 5x more information without increase bandwidth of signal. Gbps is growing but GHz stay the same
