Now here’s a clever trick, Quartarete TV and the Italian Sisvel Group have developed a new method of transmitting both Monoscopic 720P HD and Stereoscopic 3D in a single stream without any degradation of quality or display artifacts. The trick is to put them into what would normally be a 1080p stream, and slicing up the alternate eye within the unused space (as shown above).
The 3D Tile Format was developed by the Sisvel Group (and inventors Paolo D’Amato and Giovanni Ballocca) and is being developed with the CSP-Innovazione nelle ICT, a Piedmont region research and development company that works with emerging technologies to productize them. The 3D Tile Format is a series of algorithms that splits a 3-D image into three parts that are compressed in H.264 and then transmitted along with a single HD frame.
It does require special hardware to reconstruct the view (which they hope to integrate into future televisions), but it’s pretty impressive. This avoids the loss of resolution that comes with interlaced or “squished” plitscreen methods, and offers a nice “fallback” of 720P HD for folks without 3D, all in a single channel.
