MIT Developed A Movie Screen That Brings Glasses-Free 3D To All Seats (techcrunch.com) 100

An anonymous reader writes from a report via TechCrunch: MIT has developed a glasses-less 3D display for movie theaters. The Nintendo 3DS is one of a handful of devices to feature glasses-less 3D, but it is designed for a single users where the user is looking at the display head-on at a relatively specific angle. It's not something made for a movie theater with hundreds of seats, each of which would have a different viewing angle. What's neat about MIT's 3D display is that it doesn't require glasses and it lets anyone see the 3D effect in a movie theater, no matter where they are sitting. The MIT Computers Science and Artificial Intelligence Lab (CSAIL) created the prototype display called 'Cinema 3D' that uses a complex arrangement of lenses and mirrors to create a set number of parallax barriers that can address every viewing angle in the theater based on seat locations. It works in a movie theater because the seats are in fixed locations, and people don't tend to move around, change seats or alter their viewing angle too much. What's also neat about the Cinema 3D is that is preserves resolution, whereas other glasses-less 3D displays carry cots in terms of image resolution. The prototype is about the size of a letter-sized notepad, and it needs 50 sets of mirrors and lenses. It should be ready for market once researchers scale it up to a commercially viable product.

Part of the issue is that Verizon is a last-mile network, and does not sell symmetric bandwidth to its subscribers. So, the typical agreement between providers - where they each send about the same amount of traffic to each other and upgrade the interconnects to handle that traffic - will not work between Verizon and Level 3. Verizon (and the vast majority of other last-mile providers, including Comcast) will NEVER have a balanced interconnection with Level 3, because the home subscribers can all download far faster than they can upload.

Really, it's Verizon's customers who are causing all this bandwidth usage, so it should be Verizon ensuring that their interconnects can handle the requested bandwidth. If anything, Verizon (and Comcast) should be paying Level 3 for additional download capacity... but we all know that is never going to happen.
