World’s first broadcast of backward compatible 3D TV -
World’s first broadcast of backward compatible 3D TV

Yesterday, in Turin, at the headquarters of the Piedmont Region, a news conference was held announcing the implementation, from Piedmont, of the first 3D HDTV broadcasts, free-to-air, with a system for backwards compatibility with 2D TV sets. The initiative, all made in Piedmont, was created through a partnership between public and private bodies operating in the area, putting the region, in northwestern Italy, at the forefront in Europe for developing leading technology for future years.
With the start of digital terrestrial TV 3D broadcasts within the Quartarete TV service bouquet, Piedmont also becomes the first region in Italy to broadcast free-to-air, backward compatible 3D TV content, allowing those with HD TV sets to watch 2D HDTV, even when the transmissions use 3D techniques.
This is possible due to an innovative technique for formatting stereoscopic images, known as 3D Tile Format, which makes it possible to integrate two 720p frames within a single 1080p frame. The reconstructed right and left images maintain their original resolution, preventing an unbalancing of the vertical or horizontal resolution.
The 3D Tile Format improves the quality of the transmission of 3D HD content, compared to current solutions (Side-by-Side or Top-and-Bottom) and, due to its backwards compatibility, allows broadcasters to transmit to both 2D and 3D users without having to double the amount of bandwidth required for transmissions.
