New 3D Backward-compatible Broadcast DTV System Launched
TURIN, ITALY:
A broadcast and technology consortium in Italy is demonstrating an over-the-air
digital 3DTV system that is backward-compatible with 2D TV sets, according to
one of its members. The group held a news conference last week in Turin
announcing the implementation of the system in the northern Italian region of
Piemonte.
Participants included Sisvel Profile, CSP Innovazione nelle ICT and Quartarete
TV, which is now carrying the service that ostensibly allows “those with HD TV
sets to watch 2D HDTV, even when the transmissions use 3D techniques.”
Sisvel said the backward-compatibility was 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 is said to improve the quality of the transmission of 3D hi-def
content, compared to current solutions, i.e., side-by-side or top-and-bottom.
The compatibility for regular 2D sets, allows broadcasters to transmit to both
2D and 3D users without having to double the amount of bandwidth required for
transmissions.
“3D Tile Format technology introduces considerable benefits for the entire
market,” said Sisvel Founder Roberto Dini. “The standardization bodies
themselves are assessing the adoption of our system. It is worth emphasizing
that this is a project which offers a positive image of the country, as the
entire value chain of the technology, including the set-top-boxes for receiving
the signal, has been developed and produced in Italy.”
