[citation][nom]lockhrt999[/nom]Nevertheless I did a few calculations a while back. Uncompressed 60Hz 1080p video data in RGB format can't be transferred over a gigabit ethernet connection as bandwidth is insufficient. So video compression is in the order (Yeah lossless compression will do, i suppose).[/citation]
Then use CAT6, can rate up to 10 gig, and if you use 2 cable solution that covers any overheads too if you think you are getting close - but you wont as even 4K video wont stress that bandwidth

IMO, HDMI are redundant, it shouldn't even be exist at all, it is the most stupid technology. Cat5e/6 can be use for AV transfer, as well as Internet usage, it is much more superior to HDMI.
 
Yeah, HDBaseT products have been out for a while now, even before the standard was published. Crestron is by far the biggest name is digital transport technology in the AV market. Yes, there's a large demand for it. A Crestron rep said that their DM Line was about 40% of their sales for last year, would would amount to roughly $200M. This type of technology is used in the commecial AV market, not really broadcasting, and not prosumer. More for your college and university settings, corporate spaces, auditoriums, etc. These are often part of a larger AV system and not just a transmitter end and a receiver end. Often these feed larger systems that offer matrix switching and various exotic control aspects. I've installed a school where classrooms had an HDMI/VGA input box and a projector all going to a centralized location in the school. Each room only required two Cat5e runs to the centralized area and that was it. The input box was one and the projector was another.

The reason it's popular is because of the distance limitation of HDMI as mentioned, not to mention that HDMI cables aren't really field termination friendly, and don't fit in conduit. Cat5e is cheap and already pulled throughout most buildings, not to mention everyone knows how to terminate it and has the tools.

Other members who utilize HDBaseT technology include: AMX, Atlona, Extron, Gefen (mentioned in article), Kramer, and Magenta.

The transport standard (not everyone uses all aspects) should fully support everything that's included in the HDMI standard, ethernet, RS232, USB, power upto 100W, and maybe some other stuff I'm missing. Some displays will run on a single Cat5e without an additional power cable. They had one rigged up at Infocomm, I believe the PrimeView PRV42WRCHDBT is the panel. Panasonic has a line of projectors coming out (or recently out) that have HDBaseT jacks directly in the back of them, though of course even if the switch that feeds 100W was easy to get projectors take up way more than that.

Other digital transport technologies include over fiber. This is not standardized like the copper solution, so what each manufacturer includes varies wildly. For example, AMX doesn't support HDCP on their fiber solution (yet). Crestron has a single mode fiber that should transport everything in the copper solution (minus power of course) 7.5 miles. Yeah, Tom doesn't have a whole lot of AV coverage as this stuff's all been out for a while, hopefully our market will get some good attention in the future.
 
$1000 for 100m? HA!

Or you could HDCP stripper, HDMI recorder, run it into your computer, and stream it to another device wherever needed. Across the world if you cared to (and had the internet speeds, those you'd need a very good computer for compression). Depending on your current computer, it's likely cheaper (minus the crazy internet streaming part).

Again, it's for commercial use. What you are saying is illegal, and even though there's no reason you can't or shouldn't do that in your house, if an integrator does that in a commercial application it's a large liability, not to mention that an integrator does stuff like this, they are also likely skimping and duct-taping your system everywhere else. Other problem would be if the HDMI cable fails and needs reterminated, or if you pull 100' cable and find yourself with an extra 50' of cable at one end, what are you supposed to do other than coil it all up on the floor/repull it with a shorter cable?

$1000 is probably a lot more than you'd pay for Atlona, and I've had bad experiences with Gefen in the past anyway. I think you're probably looking for something in the $300 with a different brand or less.
 
you know, i have no freaking idea why this is happening, but everytime i try to post some 4-1-1 on something, these forum's are blanking all or parts of it out.

what i have attempted to say, again, was that there is a 133' hdmi cable w/equalizer at monoprice for less than $100.

I have looked over the hardware at monoprice and dont see anything there taht would do what the Gefen does. It would be nice to have an alternative to the Gefen that is cheaper. As has been mentioned by others in the comments this is a device for commercial use.
If you look at Walt Biscardi's anatomy of an editing suite you can see where he uses two Gefen boxes. They are located in the main computer room with all the servers and all actual computers. The receivers for the Gefens are in the editing suites connecting the mouse, keyboard (via usb)and monitors(via dvi). That is one example of what this is designed for. I agree that in mainly a/v situations I would go with something from monoprice.
 
I would recommend checking KVMSwitchTech. They offer long range HDMI Extender and USB 2.0 Extender solutions that are EDID and HDCP compliant. You can extend up to 330ft with full 1080p support.
