The Blu-ray
Disc Association created a task force made up of executives from the
film industry and the consumer electronics and IT sectors to help
define standards for putting 3D film and 3D television content on a Blu-ray Disc. BDA officially announced 3D specs for Blu-ray Disc, allowing backward compatibility with current 2D Blu-ray players. "The Blu-ray 3D specification calls for encoding 3D video using the "Stereo High" profile defined by Multiview Video Coding
(MVC), 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." This means the MVC (3D) stream is backward compatible with
H.264/AVC (2D) stream, allowing older 2D devices and software to decode
stereoscopic video streams, ignoring additional information for the
second view.
