    This is not a direct translation, but rather the gist from the original German article. Please forgive the shitty English.

    The first two cylinders are supposed to be installed in March of 2004. They plan to connect all European capitals by 2008. The plan is to have them feature views from other cylinders in the "best picture quality". Additionally people will be able to contact their counterparts at the other cylinder in "sound and picture"

    The cylinders seem to cost about two million Euro a piece. They plan to earn money by selling advertising. The advertising will be limited to a maximum of 13% "airtime". Since they plan to be on air 24/7 that translates to 192 minutes of ads per day. They will sell advertising time to "exclusive content-partners" to "not endanger the THOLOS concept" and stop any "dilution" through additional programmes.

    Inside the cylinder you will find eight HDTV-projectors, 22 microphones, 22 loudspeakers and three cameras. Networking is done via 100 MBit-Lines. To protect from vandalism the glass walls will be coated with a "special nano-structured anti-graffiti-protective-coating". And they want to hire security personnel to keep an eye on the expensive hardware around the clock.

    In Japan, at the Yokohama central train station there is a large cylindrical television about 2 meters in diameter. It's visually quite impressive and the colors are good. When you touch the glass you can feel the powerful hum of the revolving drum inside. From examining photographs of the outside of the cylinder taken at various exposure times, it appears it's made with approximately 24 groups of 3 vertical LED bars, one for each primary color.

    These bars sweep by the viewer at great speed and 'paint' each pixel dozens of time per second. Similar to DLP projectors, each pixel is illuminated in turn by the different colors. When you look close on one pixel, you can see it's sort of fluctuating. What you're really looking at is a rapid progression of dozens of different colored LEDs flashing their light at you at the same physical point in space. The final result is a very smooth and stable image with a high refresh rate, great brightness and very rich LED colors.

    I wonder if a technology similar to the one above will be used for these booths. Although a busy train station at a major earth quake zone could be considered a particularly hostile environment for a precision engineered rapidly rotating drum of considerable mass, I could easily imagine some european capitals constituting an even more hostile environment in terms of rampant vandalism.

    The technology required to build these things are probably nothing much special, but I think it's a fun neat idea. Perhaps each drum will be switching between cities on regular posted hours and according to some kind of schedule so you can plan ahead to "meet" a friend from another city. These things should be placed by plazas and intersections with lots of pedestrians.

    Another thing - just 3 cameras? That'll probably mean highly oblique angles for most of the people standing right next to the drum, which in turn might mean you don't get all that much out of 'meeting' someone. It would be something truly special if you could look directly at the virtual representation of someone standing right alongside the remote screen and they'd look right back at you.

    As I see it, this is a free, virtual window into another city. Very nice for separated love couples in two different cities: "Let's meet at the cylinder" etc.. And funny for innocent passer-bys that can see wave and say "hi" to people from another city.

    However, I think the most critical question is: will people be able to look into each other eyes like you would when you are looking trough a real-world window? Well the answer lies in the german article [heise.de]: "Im Inneren eines Zylinders sind sechs HDTV-Projektoren, 22 Mikrofone, 22 Lautsprecher und drei Kameras untergebracht" - "Inside the cylinder there are 6 hdtv projectors, 22 mics and 3 cameras". Only 3 cameras! How will it be possible for more than 3 people to look into their eyes then? Not at all, methinks...

    I think not being able to look into each other's eyes through this virtual window will reduce the coolness factor of the cylinder to an overhyped TV/webcam combo...
    • Since when did it become a problem to have cameras that could capture 120 degrees each?

      • The problem is that for true eye-to-eye communication, for every eye that looks into the screen, you will need a camera at the other city to cover the view (think 3D, and think people are not always perfectly perpendicular to the screen).

        Which of course means a lot more cameras, a lot more bandwith or a very clever 3D simulation. But a very clever 3D simulation still needs more than 1 camera for 120 degrees to work its magic.
    • I've been wondering about that as well. They must be really wide-angel cameras for a 360 view with only three of them. So, if you both (from different cities) do not stand right in front of the camera, it would look like you are both looking at another point (the center of the camera) when in fact you are standing right in front of each other.

      On the other hand, having only three cameras keeps the necessary bandwidth low of course. Three video streams with hdtv quality should already need quite some bandwid

        In other words, anyone looking directly at the circle appears to be looking directly out of the circle on the other side, no matter what their position is in relation to the

    What bothers me is that there is no sign of any technical specifications at all.

    20 mega pixels - five times HDTV resolution

    Sure, very nice if they were to show it on a screen as large as a 28" TV, but on a screen with an area of 66 m^2? 560 pixels/m? That doesn't sound very highres to me.

    Lets calculate bandwidth. 20 Mpix = 20971520*24*3 = 1440 MB/s, uncompressed. That's a lot. Let's say they manage to compress the video 20 times, which could be difficult or expensive with real time compression. That leaves us with 72 MB/s video only over far distances, excluding sound. How are they going to get that through the 100 MBit network they mention in the article?

    Also, I can find no references from google regarding "Hypersound(C), a revolutionary directional sound technology". If it was that revolutionary, someone would have written something about it, you might think.

    I really don't know. It's a cool idea, but it sounds fishy. Is there a working prototype at all, or are they still in the attract-investor-money phase?
    • Of course it is not "20971520*24*3 = 1440 MB/s, uncompressed". It is 20971520*24 = 480 MB/s. 24 MB/s , compressed 20 times without audio. Still, a bit much for a 100 MBit network to handle.
    • You're a little off on the math, but close.

      20MegaPix = 20971520 pixels
      Times 24 Bits per Pix
      HDTV uses 29.97 Frames per second
      Times 3 cameras.
      20971520 * 24 * 29.97 * 3 = 43156.8 MegaBits or 5394.6 Megabytes.

      Now, using multiple 100Mb connections it would take 432 connections just to handle the uncompressed data.
      Someone remarked that Divx can compress 100:1 with no loss. I use video compressors alot. Divx has horrible loss, especially with high resolution. Not to mention you'd have to compress the video 432:1

    This project is a rework of the infamous Hole in Space [ecafe.com] project, dating back to 1980.

    This project consisted in linking together by audio and video two public spaces, without telling the passerby anything about the installation. At some point, bystanders would realize the link was bidirectional and started impromptu conversations between the two locations.

    By a funny twist of things, this project inspired much of the 1980's and early 90's work carried at Xerox PARC and the University of Toronto Telepresence [toronto.edu] project.

    These in turns nurtured a number of startups, such as PictureTel/Polycom, still a leader in videoconferencing technology.

    Notice that by the time, the technology was fully analog, and for having used it in the early 90's, I can say the link quality was far better than most current IP-based videoconferencing is today.

    I think it's a brilliant idea. It has little practical use apart from a sort of virtual meeting point, but I can see this becoming a huge hit. Normal people, who unlike us geeks, will not be worrying about bandwidth, bitdepth, framerates etc will love the idea.
  • This is the sort of thing that politicians love and will have their picture taken standing near it. It will attract large crowds for awhile. In three years it will sit idle due to budget cuts with a sign reading "Temporarily Out of Order"
  • Actually sounds like a good idea, i've seen big screens being wasted on much more pointless projects (namely that stupid coke sign that looks suspiciously like a giant flash application).

  • So this is the phonebooth of the 21st century. How cool would this be if they shrunk it down and just made life-size video conferencing booths?
