This was announced at last years Cedia but I have not heard any more about it.
I see Gefen is taking pre orders. Multiple video formats: 480p, 720p, 1080i and 1080p @ 24/30.

Not bad. Id like to see this spread to other electronics.

This is one thing that will make CRT installations easier.
"Oh sorry, I thought you only needed a single coax wire to the ceiling"
;)
I also run across that a lot in retrofits. Once this technology matures, I'll dive right in.

I can't wait. I went to three customer sights this week, two of which had "pre-wire" jobs that consisted of coax only ran to high def television spots all over the house, what a joke. Both of them were finished upper end housing without any chance of opening back up the walls (one had custom wood everywhere, good luck to that) so this could be a lifesaver soon. I've been keeping my eye on it for months now, praying that it works well considering all the HDMI issues ive had over the last year or so. Hell, I wish someone did a wireless component video box, that would be fine too (if they do, let me know!)

Hold your horses, folks. This product claims "visually lossless HD compression." If it's truly lossless, then they would say so; saying "visually lossless" suggests that the compression is, in fact, lossy---but that we shouldn't see the difference. Well, I'll believe that when I see it. See this FAQ. (http://www.jpeg2000info.com/what/comp101.html)
The literature claims a data rate of up to 480Mpbs. 1080p30, which is the highest-bandwidth signal they claim to carry, is 1.49Mbps or so. That means they have to achieve at least a factor of 3 compression in order to fit the video through the pipe. (EDIT: I say "at least" because the data rate is up to 480Mbps; your mileage may vary.) Honestly, that's probably doable...
...but they seem to have explicitly left out 1080p60...
I'm not ready to give up my cable yet.

I don't think this is going towards giving up cabling as much as it is for situations like mine when the clients pre-wire guy tells me "err duhhh errrr we didnt talk about hddddd errrrrr uhhhhhhhhhhh i gotta go" :(
compressed hd is better then nothing I guess

I wonder as well, how the wireless freqs will do. We are seeing alot more problems now and know of some to come in our wireless microphone band and also our wireless clear com systems. The spectrum is getting crowded.
I agree though in a pinch this thing has some great uses.

Yeah, to be honest, maybe for source material that is already compressed, a 3:1 JPEG2000 compression isn't going to matter much. The proof will be in the viewing.
But you still can't feed it 1080p60, which means that your projector is likely going to have to do some deinterlacing (for, say, true 1080i60 content).
If the processor in the projector isn't up to snuff, then maybe you can put an outboard HDMI deinterlacer/scaler next to the projector and stream wireless HDMI into that instead. At least then you won't have to worry about trying to pass 1080p60 through the air; you can keep it all at its source resolution.

Wise words..;) Beware the installer that uses wireless anything as a cure-all. Wired is still the best way to go.
