Wireless HDMI Prototype Announced

legoburner writes "Tzero Technologies and Analog Devices announced that they have created a wireless HDMI interface for HDTVs, next-gen DVD players, and set-top boxes. The backbone for the technology is ultrawideband, also used as a future replacement for wired USB. The Analog Device compresses data with the [lossy] JPEG2000 video codec, which is then packetized and encrypted, and transmitted via the Tzero MAC and PHY chip."

  1. HD compression? by MindStalker · · Score: 3, Insightful

    Ok why would someone spend large amounts of money on an HD system only to have it compressed.

    On another note, what about the signal band already used by HD TV broadcasters, would a signal thats weak enough to stay inside your house be legal?

      Because they are posers and just want to look like they have expensive equipment? That would apply to quite a few people with top-of-the-range systems that I know of.

  2. Not really HDMI by Anonymous Coward · · Score: 2, Insightful

    HDMI, in its present incantation, is just glorified DVI with DRM. But, anyways, a wireless version of a video connection which is lossy is not the same as the video connection it purports to replicate. I would propose they call it HDMI Minus (or something like that) but HDMI is already a minus.

    If lossy is allowed, my regular CRT TV from 1998 could be called HDTV. It's just lossy, right?

      I have learned that the wireless equivalents are always well under the performances of the wired ones. And I'm tired to see my image freeze every time someone walks between the Wi-Fi access point and the HTPC.

      Wireless is a no-go, in any of its incarnations today, save the input devices which don't need high data rate: mice, keyboards, remotes. All the rest is just on an emergency basis.

    Just because it was true in the 1950's and kind of has a caveman feel to it, doesn't mean there isn't a ring of truth to it. If you go over to http://www.avsforum.com/ you'd be surprised as to the number of posts talking about passing the spouse test regards to being esthetically pleasing on required cable hiding, etc.

  4. No Lessons Learned from the 2.4GHz Spectrum by JungleRob · · Score: 1, Insightful
    The standard calls for link reliability of at least 95 percent, packet error rate of less than 1 in one hundred million, interference resistances for microwaves and cordless phones, and the ability to process three or more HD streams at 10 meters.

    From Intel's Website:
    In the United States, the Federal Communications Commission (FCC) has mandated that UWB radio transmissions can legally operate in the range from 3.1 GHz up to 10.6 GHz, at a limited transmit power of -41dBm/MHz.

    Unregulated frequencies are historically hot beds of interference. Does this 1 packet error in 100,000,000 include the use of a 5.8GHz cordless phone near by. Not to mention multiple UWB devices like wireless USB. I'd like to know how this technology was tested to understand how they calculated such a low error rate. Have we learned anything from the 2.4GHz spectrum?

    My wife's only complaint with my home theater set up was all the wires and how best to hide them. She was totally against me using surround sound because of the wires. Finally I ran the wires under the flooring (it's complicated) and then it was no problem. So in reality these guys have a good point.

    You can get hihg quality HDMI cables from monoprice.com for $12 or less.

    Only a complete retard would pay $100 for a cable meant to deliver a purely digital signal. Then again these are the same people Monster-brand products are amrketed to, so nothing surprises me.

  7. I'll tell you what... by Overzeetop · · Score: 4, Insightful

    How about we concentrate on getting systems which will modulate the original, compressed HD over coax so that 99% of the population who owns a house that is already built around the old way of doing things can still watch TV without fishing cable around?

    C'mon folks, there's a hundred usable channels with 19.x Mb/s effective bandwidth so we could *in theory* just pipe that HD signal from a remote box to the tv with the existing wires, let the ATSC STB (or internal tuner) demodulate and decode the content and display it. Hell, we could all have everything-everywhere in our houses with all the ugly gear stashed in the basement with this standard. *Analog is not the enemy* OTA HD works damned fine. Why fuck it up with expensive, unnecessary cabling?

    Disclaimer - yes I have an older home. I also have the DVD jukebox on channel 40, my Tivo on 45, my wife's tivo on 50, and a media server on 55. They get combined with the off air antenna and piped through an RG-59 coax to every TV in the house, with a Xantech IR sensor (DC coax return) at each TV. It works great, except that there's no HD. My parents just bought a new house, but can't put HD in the rooms because the builder ran (the standard) one coax to each TV location. Suprise...DTV requires 2 to get HD (I haven't verified this, mine are old TiVo units with two tuners, and need two cables).

    Is it just my observation, or are there way too many stupid people in the world?

    The 1950s called. They want their mentality back.

    Which just goes to show how cool the 50's really were.

    Seriously, after decades of political correctness, we see that some stereotypes aren't always that far off. These guys aren't guessing that women want this, it's part of the feedback/research. My own experience (my wife and her friends) supports this. I know, my own experience doesn't offer a sample size large enough to reject the null hypothesis but it makes it a little easier to believe when I hear someone else say he same thing.

    My big concern is that the very people who have HDMI, particularly at this point, are not very likely to be interested in risking any video quality for the sake of wireless.
