2D-plus-Depth or also called 2D + Z format (not to be confused with 2D plus Delta or 2D-plus-DOT) is a Stereoscopic Video Coding format that is used for 3D displays, such as Philips WOWvx. Philips discontinued work on the WOWvx line in 2009, citing "current market developments". Currently, this Philips technology is used by Dimenco company, led by former key 3D engineers and scientists of Philips. They offer autostereoscopic 3D displays which use the 2D-plus-Depth format for 3D video input.
