- Considering all of the press
Sony has already got for PS3 3D gaming, it's no surprise that the PlayStation 3 meets Blu-ray 3D compatibility specifications as announced by the BDA (Blu-Ray Disc Association) today.
Press Release from Blu-ray.com (linked above): The Blu-ray Disc Association (BDA) today announced the finalization and release of the "Blu-ray 3D" specification.
It leverages the technical advantages of the BD format to deliver "unmatched picture quality" as well as uniformity and compatibility across the full range of Blu-ray 3D products, both hardware and software. The specification is also designed to allow the PS3 to play back Blu-ray 3D content in 3-D.
Notably, the specification allows every player and movie supporting it to deliver full HD 1080p resolution to each eye. Moreover, the specification is display agnostic, meaning that Blu-ray 3D products will deliver the 3-D image to any compatible 3-D display, regardless of whether that display uses LCD, plasma or other technology and regardless of what 3-D technology the display uses to deliver the image to the viewer's eyes.
Regarding compatibility, the specification supports playback of 2-D discs in forthcoming 3-D players and can enable 2-D playback of Blu-ray 3D discs on the installed base of Blu-ray Disc players currently in homes around the world.
The Blu-ray 3D specification calls for encoding 3-D video using the Multiview Video Coding (MVC) codec, an extension to the ITU-T H.264 Advanced Video Coding (AVC) codec currently supported by all Blu-ray Disc players.
MPEG4-MVC compresses both left and right eye views with a typical 50% overhead compared to equivalent 2-D content, and can provide full 1080p resolution backward compatibility with current 2-D Blu-ray Disc players. The specification also incorporates enhanced graphic features for 3-D. These features provide a new experience for users, enabling navigation using 3-D graphic menus and displaying 3-D subtitles positioned in 3-D video.
The completed specification will be available shortly and provides individual manufacturers and content providers with the technical information and guidelines necessary to develop, announce and bring products to market pursuant to their own internal planning cycles and timetables.
"Throughout this year, movie goers have shown an overwhelming preference for 3-D when presented with the option to see a theatrical release in either 3-D or 2-D," said Victor Matsuda
, chairman, BDA Global Promotions Committee. "We believe this demand for 3-D content will carry over into the home now that we have, in Blu-ray Disc, a medium that can deliver a quality Full HD 3-D experience to the living room."
"From a technological perspective, it is simply the best available platform for bringing 3D into the home," said Benn Carr
, chairman, BDA 3D Task Force. "The disc capacity and bit rates Blu-ray Disc provides enable us to deliver 3D in Full HD 1080p high definition resolution."
"In 2009 we saw Blu-ray firmly establish itself as the most rapidly adopted packaged media format ever introduced," said Matsuda. "We think the broad and rapid acceptance Blu-ray Disc already enjoys with consumers will be a factor in accelerating the uptake of 3-D in the home. In the meantime, existing players and libraries can continue to be fully enjoyed as consumers consider extending into 3-D home entertainment."
A note on spelling: Earlier this year, the blu-ray.com team unanimously decided to use the spelling "3-D", with a hyphen, for everything related to stereoscopic images, and "3D", without a hyphen, for three-dimensional graphics and animation. We shall continue to do so, except when citing the name of the "Blu-ray 3D" specification, which doesn't use the hyphen.
