Multiview Video Coding (MVC) is a modified version of the AVC codec created in 2009 for 3D video. It uses a Polarized 3D system (using the 2D+Delta method) that uses two separate images projected superimposed onto the same screen through different polarizing filters.
Compared to classic anaglyph images, the use of polarized 3D glasses produces a full-color image that is considerably more comfortable to watch and is not subject to binocular rivalry. It is like AVC but provides a secondary video for the right eye called the MVC-dependent view. The main MVC video for the left eye is called the MVC-base view.
The MVC Base view video stream is compatible with the normal AVC video stream so that 2D players can decode MPEG-4 MVC Baseview video stream for 2D playback. The developer can choose that either the left or right eye stream is the MVC Base view video stream to be used by a 2D player as the source for the backward compatible 2D stream.
MVC files contains supplemental enhancement information (SEI). SEI messages can contain various types of data that indicate the timing of the video pictures or describe various properties of the coded video or how it can be used or enhanced.
Strangely, their are some BD3D titles that are not compatible with normal 2D players (Avatar: The War of Water), but they normally contain a normal 2D disc. It is unknown on why these discs will not play, but in speculation it could be DRM reasons.
MVC video is stored in the Stereoscopic Interleaved file .ssif, which is composed of M2TS files. This file is used only when 3D video is played back.
Unlike, AVC, there's currently no opensource implementation of MVC and it's mostly covered by patents (mostly from Panasonic).
