2D plus Delta
Encyclopedia
2D Plus Delta is a standards listed methodology as part of MPEG2, and MPEG4, specifically on the H.264 implementation of Multiview Video Coding
extension. This technology originally started as a proprietary method for Stereoscopic Video Coding
and content deployment that utilizes the Left or Right channel as the 2D version and the optimized difference or disparity (Delta) between that image channel view and a second eye image view is injected into the videostream as user_data, secondary stream, independent stream, enhancement layer or NALu for deployment. The Delta data can be either a spatial stereo disparity, temporal predictive, bidirectional or optimized motion compensation
.
The technology was originally filed for protection World Wide via WIPO in 2003, submitted the patent statements to ISO in 2007 and listed as part of the MVC standard in 2008 and is now considered as an Open Standard available for licensing and usage under a world wide, non-discriminatory basis and on reasonable terms and conditions.
The MVC initiative
was started in June 2006.
The resulting videostream has the following characteristics:
2D Plus Delta has been listed at ISO/ITU/IEC/MPEG2/MPEG4/MVC initiatives.

Motion compensation
Motion compensation is an algorithmic technique employed in the encoding of video data for video compression, for example in the generation of MPEG-2 files. Motion compensation describes a picture in terms of the transformation of a reference picture to the current picture. The reference picture...

was started in June 2006.
The resulting videostream has the following characteristics:
- Contains the full information to reconstruct the Left and Right stereoscopic views in full resolution per eye
- Requires an additional average bandwidth ranging from 30% to 60% regarding a 2D only stream depending on the encoding implementation
- Can be deployed over existing pipelines, starting from 16Mbits/s for 1080p@60fps per eye
- One single videostream services both: 3D viewers and 2D Legacy users
- Can be seamlessly decoded by 2D legacy decoders in full 2D HD without the need of any change or additional hardware

A 3D television is a television set that employs techniques of 3D presentation, such as stereoscopic capture, multi-view capture, or 2D-plus-depth, and a 3D display – a special viewing device to project a television program into a realistic three-dimensional field.- History :In the late-1890's,...
