Gefen's HDMI-Over-Coax Means No New Wires for HDTV Everywhere

Illustration for article titled Gefens HDMI-Over-Coax Means No New Wires for HDTV Everywhere

Gefen says it's figured out exactly how to move HDMI signals over the coaxial cable that already exists in many homes all over the world. The company plans to show the technology at CES next week that it says will ship in April. Gefen has been working on this tech that could make it much easier to move HDTV signals all over your house for a while, in fact, we saw a working demonstration of HDMI over coax at the National Association of Broadcasters (NAB) convention last April. But there's a twist that makes it a lot more convenient.

Now the company's added a back channel that lets you transmit infrared signals back to the source, controlling your components over coax, too. Neat. Maybe now that Gefen has teamed up with Pulse~LINK, a company that's pretty good at squeezing HD signals through various cables, this will move beyond vaporware and into the real world. It sure could be useful, sending HDMI signals all over a house that's already wired with coaxial cable. [Gefen Press Release]

About time...I cannot wait for Geffen to come out for this product. I currently have a "central media closet" that houses all my components and have tons of RG6, Cat5 and a few HDMI runs that all feed and terminate in different rooms with HDTV. I am currently limited as I cannot run HDMI over 25~30ft without the picture/sound dropping. One of my TV's in the kitchen with an HDMI connection and Component but only has one cable coax connection as I forgot to run extra RG6 here to view at least an HDTV signal from my HD Distro amp where my Directv feed is in for the whole whose. Sweet product but at a cost!! Gefen always had some of the best switches/scalers/converters/extenders but pay a $hit load for them.

Also I agree how people quickly forget that good old reliable analogue RG6 connections are still the dominant use in today's professional A/V market. What do you think today's custom installers use to run long runs of cable to feed multiple TV's with HD signals? Yep-you got it, RG6 or HD-SDI. Sure HDMI1.3 can support both a/v on one run but is limited and yes I understand it also supports true 1080p whereas comoponent RG6 doesn't. I currently have bundles of RG6 going to each room and feed my Directv HD signal using a Ditro Amp and the picture looks amazing whether it is a 720p or 1080i signal. Of course I use HDMI from my HD Players to my TV directly but are short runs only at 3m (6ft). In reality there isn't much of a picture signal quality difference on RG6 cable vs. HDMI on a true matchup of 720p and 1080i signals. Besides what do you think ALL electronic specialty and retail stores use to feed all those TV's on the wall with HD signals? Check it out next time, you will notice they use HD-SDI/RG6 cabling to run all those feeds from one Distrobution Amp. It's all about cost and the stupid Copy-Protection the studios want hence HDMI.
