TDVCodec
TDVision developed and patented world wide the 2D+Delta method of Stereoscopic Video Coding for an encoding and decoding method in 2003, also called the TDVCodec. Key features of the encoding format include up to Full HD (1920x1080) per-eye stereoscopic resolution, and 2D backwards compatibility with existing televisions and Cable television, Satellite Television, Blu-ray, ATSC decoders and PC based systems.
The first demonstration of a full HD 3D Blu-ray Disc running on 2D+Delta and compatible with 2D legacy players in the world was made by TDVision in April 2008 during the National Association of Broadcasters (NAB) Trade Show in Las Vegas, Nevada, as recorded on the press release Stereoscopic 3D Content at Home, Brought to You By TDVision's TDVCodec and then mentioned on the article 3D Blu-ray Closer to Reality in May 2008. The company was then listed as key IP holder on the MVC standard on the ISO JTC Patent Database and the initiative evolved to what is now known as the selected spec of the Blu-ray Disc Association as mentioned in the article Final 3-D Blu-ray Specification Announced where all the characteristics of the 2D+Delta method were confirmed:
"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."
