Blu-ray Finalizes 3D Spec
The Blu-ray Disc Association announced finalization and release of its Blu-ray 3D specification. The specification, which represents the work of the leading Hollywood studios and consumer electronic and computer manufacturers, will enable the entertainment industry to deliver the 3D experience on Blu-ray Disc.
The Blu-ray Disc Association (BDA) announced finalization and release of its Blu-ray 3D specification. The specification, which represents the work of the leading Hollywood studios and consumer electronic and computer manufacturers, will enable the entertainment industry to deliver the 3D experience on Blu-ray Disc, according to the group.
"Throughout this year, movie goers have shown an overwhelming preference for 3D when presented with the option to see a theatrical release in either 3D or 2D," said Victor Matsuda, chairman of the BDA Global Promotions Committee, in a statement. "We believe this demand for 3D content will carry over into the home now that we have, in Blu-ray Disc, a medium that can deliver a quality Full HD 3D experience to the living room."
Association officials said the Blu-ray 3D specification leverages the technical advantages of the Blu-ray Disc format to deliver picture quality, uniformity, and compatibility across the full range of Blu-ray 3D products, including hardware and software. The specification allows every Blu-ray 3D player and movie to deliver full HD 1080p resolution to each eye, thereby maintaining the image quality to which Blu-ray Disc viewers are accustomed, according to BDA.
The specification is display-agnostic, meaning that Blu-ray 3D products will deliver the 3D image to any compatible 3D display, regardless of whether that display uses LCD, plasma or other technology and regardless of what 3D technology the display uses to deliver the image to the viewer's eyes.
The Blu-ray 3D specification is also designed to allow PS3 game consoles to play back Blu-ray 3D content in 3D. Additionally, the specification supports playback of 2D discs in forthcoming 3D players and can enable 2D playback of Blu-ray 3D discs on the large installed base of Blu-ray Disc players currently in homes around the world.
The specification calls for encoding 3D 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 2D content, and can provide full 1080p resolution backward compatibility with current 2D Blu-ray Disc players. The specification also incorporates enhanced graphic features for 3D. These features provide a new experience for users, enabling navigation using 3D graphic menus and displaying 3D subtitles positioned in 3D video.
