After I wrote about Telstra claiming an Australian first with a 3D TV installation in its Telstra “Executive Briefing Centre” in Melbourne’s CBD, in conjunction with its partner Prime Digital Media (PDM), I realised I had some more questions, so Telstra invited me to come and visit, take a look and get some answers. As mentioned in the first story, 3D TVs aren’t new – they’ve been demonstrated for year at technology shows in two forms: models that require you to wear special 3D glasses, and models that don’t. One thing I’ve noticed with models that need no glasses is the fact that the resulting image can look a little bit fuzzy, and I asked if the screen on display was a high-def screen, or not, and how it was able to create a 3D image. The short answer is that the screen is indeed a 1920x1080 high-def plasma panel, called the “NewSight Multiview”. I went to NewSight’s website for some interesting technical detail on exactly how the screens work, but I've summarised it below, with answers on how and why Telstra is deploying the technology in Australia on page 2. Newsight explains that its “patented technology supports creation and display of three dimensional images that are viewable without glasses” and that they “use a proprietary technology with numerous patents in throughout the world covering 3D autostereoscopic display systems and software.” Telstra’s representatives told me the plasma TV has 8 layers (a parallax barrier) atop the standard glass, with NewSight’s technical explanation being that it uses “parallax barrier technology allows the viewer to see the 3D image “naturally” in the way people are used to viewing normal 2D displays.” The explanation continues: “The technology subdivides the LCD image into complex repeating segments that, when viewed and then integrated by human binocular vision, presents 3D views of scenes. The special parallax barrier is affixed to commercial-grade LCD displays in a precision assembly process.” The parallax barrier causes the slightly fuzzy look, something that you don’t see with units that require 3D glasses, but given that you don’t need glasses and anyone can experience the 3D vision, the slight fuzziness trade-off is more than worth it. So why is Telstra getting into the 3D TV advertising business, when telecommunications is what it does? Turns out the answer is quite simple... Please read on to page 2. On page 3 you’ll find more information on the 3D video creation process, as well as tech specs for the screens and screen sizes. |
