NAB07: Gefen's Wireless HDMI is a Work in Progress

yeah it's how manufacturers leech money off each new technology... coax can handle HD and more... but there's no hardware that will allow you to do so.. in this case it's almost like it's proprietory, requiring HDMI and component to be the only 2 standard (retail/consumer) available to the masses.

Of corse coax can do hi-def. It's called HD-SDI, and has been widely available longer than HDMI. The HD-SDI spec even allows for embedded audio. The problem? The spec does not provide for encryption (but FYI--the spec for HDMI for display devices does mandate for allowing non-encrypted HDMI input). Gefen will likely just be using some sort of encryption--on the coax path--to keep the Powers happy, and eveything legal. HDMI handles 1.4 Gbps bandwidth, as does 75 ohm coax. If you had a non-encrypted HDMI source, you could use any of the available HDMI-->HD-SDI converters to pass HDMI across coax, today. But Gefen's solution will be slicker, less fidgety, embed your AC3, etc. etc.

Well, dkoemans, the problem is that if you want to plug your HDMI component into your HDMI TV, you have to use an HDMI cable, which only come in limited lengths. There are a number of niche applications where having components 100m apart would be very useful, such as presentations, auditoriums, conference rooms and video distribution in retail, for example.

doesn't my cable company already do this? i don't understand why it is said coax can't handle hi-def. my tv decodes hi-def signals from my cable company all day long. so logically, why do i need component/hdmi/vga from my hddvd/xbox/cable box, etc? coax can clearly handle the signal. i feel a conspiracy theory coming on.
