e/2D plus Delta

Information
has gloss	eng: 2D Plus Delta (AKA 2D+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.
