<p><b>2D Plus Delta</b> (also called <b>2D+Delta</b>) is a method of encoding a <a href="3D_image" class="mw-redirect" title="3D image">3D image</a> and is listed as a part of <a href="MPEG2" class="mw-redirect" title="MPEG2">MPEG2</a> and <a href="MPEG4" class="mw-redirect" title="MPEG4">MPEG4</a> standards, specifically on the <a href="H.264" class="mw-redirect" title="H.264">H.264</a> implementation of the <a href="Multiview_Video_Coding" title="Multiview Video Coding">Multiview Video Coding</a> extension. This <a href="Technology" title="Technology">technology</a> originally started as a proprietary method for <a href="Stereoscopic_Video_Coding" class="mw-redirect" title="Stereoscopic Video Coding">Stereoscopic Video Coding</a> 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 video stream 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 <a href="Motion_compensation" title="Motion compensation">motion compensation</a>.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>

<p>The technology was originally filed for world-wide intellectual property protection via <a href="WIPO" class="mw-redirect" title="WIPO">WIPO</a> in 2003. The patent statements were submitted to <a href="International_Organization_for_Standardization" title="International Organization for Standardization">ISO</a> in 2007, and listed as part of the MVC standard in 2008. The technology is now an open standard that is available for licensing and usage.

</p><p>The <a href="Multiview_Video_Coding" title="Multiview Video Coding">MVC initiative</a> was started in June 2006.

</p><p>The resulting video stream has the following characteristics:

</p>

<ul><li>Contains the full information to reconstruct the Left and Right stereoscopic views in full resolution per eye</li>

<li>Requires an additional average bandwidth ranging from 30% to 60% regarding a 2D only stream depending on the encoding implementation</li>

<li>Can be deployed over existing pipelines, starting from 16 Mbit/s for 1080p@60fps per eye</li>

<li>One single video stream services both: 3D viewers and 2D Legacy users</li>

<li>Can be seamlessly decoded by 2D legacy decoders in full 2D HD without the need for any change or additional hardware</li></ul>

<p>2D Plus Delta has been listed at ISO/ITU/IEC/MPEG2/MPEG4/MVC initiatives.

<li>MPEG4 ISO/IEC 14496-10:2008/FDAmd 1 - 01</li>
