The 2D Plus Depth format encrypts the video signal’s 3D left and right views into left and right fields, which are displayed as a left RGB and a Right depth map. This translation of the image’s depth data into a mathematical depth map is a major breakthrough in how 3D images are managed.
The Heinrich-Hertz Institute in Germany, originally developed this methodology under the term, “ Depth Image Based Rendering” or DIBR.

DIBR

DIBR is a math based interpretation of visual data that supports Depth Meta Data algorithm mining of the video data and translation into 256 shades of black and white gray scale depth maps, which are lightweight and re-rendered with every video frame.
In 3DTV displays for With Glasses the classical left and right stereoscopic views are displayed as a Left eye and Right eye view. In NON Philips based AS3D, this same optical format of a left eye and a right eye is “stitched” into a number of left and right multi views, up to 9, which are all based on the original left eye and right eye image.
This “ stitched” approach is a cumbersome, processor heavy and a bandwidth monster of a 3D signal which is “carved in stone”. This means that there is no real time ability to adjust or correct image issues. The 3D quality is determined by the camera capture or content creation. Any 3D image issues which must be corrected require that the content be reworked by going back to the original content and either re-shooting, re-rendering or using post production software tools to try make corrections. This process is very expensive, time consuming and limited in its ability to make corrections with no application for optimization.
The 2D Plus Depth (2D+D) PC driven Math approach revolutionized 3D video technology as it is metaphorically a rocket compared to the classical 3DTV “wheelbarrow” when it comes to 3DTV performance.
