===Stereoscopic===
[[Stereoscopic video coding|Stereoscopic video]] for [[3D film]] and other applications can be displayed using several different methods:<ref>{{Cite book |last1=Ekmekcioglu |first1=Erhan |url=https://www.worldcat.org/oclc/844775006 |title=3DTV : processing and transmission of 3D video signals |last2=Fernando |first2=Anil |last3=Worrall |first3=Stewart |date=2013 |publisher=Wiley & Sons |isbn=978-1-118-70573-5 |location=Chichester, West Sussex, United Kingdom |oclc=844775006 |access-date=August 25, 2022 |archive-date=August 25, 2022 |archive-url=https://web.archive.org/web/20220825123926/https://www.worldcat.org/title/844775006 |url-status=live }}</ref><ref>{{Cite book |last1=Block |first1=Bruce A. |url=https://www.worldcat.org/oclc/858027807 |title=3D storytelling : how stereoscopic 3D works and how to use it |last2=McNally |first2=Phillip |date=2013 |publisher=Taylor & Francis |isbn=978-1-136-03881-5 |location=Burlington, MA |oclc=858027807 |access-date=August 25, 2022 |archive-date=August 25, 2022 |archive-url=https://web.archive.org/web/20220825123926/https://www.worldcat.org/title/858027807 |url-status=live }}</ref>
* Two channels: a right channel for the right eye and a left channel for the left eye. Both channels may be viewed simultaneously by using [[light polarization|light-polarizing filters]] 90 degrees off-axis from each other on two video projectors. These separately polarized channels are viewed wearing eyeglasses with matching polarization filters.
* [[Anaglyph 3D]], where one channel is overlaid with two color-coded layers. This left and right layer technique is occasionally used for network broadcasts or recent anaglyph releases of 3D movies on DVD. Simple red/cyan plastic glasses provide the means to view the images discretely to form a stereoscopic view of the content.
* One channel with alternating left and right frames for the corresponding eye, using [[LCD shutter glasses]] that synchronize to the video to alternately block the image for each eye, so the appropriate eye sees the correct frame. This method is most common in computer [[virtual reality]] applications, such as in a [[Cave Automatic Virtual Environment]], but reduces effective video framerate by a factor of two.
