Multiview Video Coding

Multiview Video Coding (MVC ) is a supplement to the video compression standard H.264/MPEG-4 AVC for stereoscopic applications.

Description

After the patented back in 2005 developments to realize stereoscopic video recording with MPEG-2 encoding, was developed by the Moving Picture Experts Group and the Joint Video Team jointly developed the multi-view video coding standard to also signals simultaneously recorded from multiple be able to save video cameras in a codec. In July 2008, the Moving Picture Experts Group has officially approved the addition of the standard Advanced Video Coding (AVC ) for Multiview Video Coding.

Applications

Particular applications are the 3D television and stereoscopic viewing of game and animation films. Also for applications of virtual reality, such as the so-called Free Viewpoint Video ( FVV ) and the Free Viewpoint Television (FTV ), in which the viewer can determine its position and the direction of observation itself, the standard can be applied.

Playback

The Multiview Video Coding is independent of the reproduction process, so it can be played, for example, with digital screens or projectors. To view the images, shutter glasses are mostly used to draw the images with the help of electronically controllable liquid crystal layers alternately to the two eyes of the beholder. The exchange rate is so high that it is not noticed by the viewer.

Alternatively, there are methods that generate the two stereoscopic images, for example, with two projectors simultaneously with perpendicular polarization directions so that they can be viewed with polarized glasses that are vertically aligned polarizing filters and therefore not equipped with electronic aids with two.

Also for mobile playback devices, corresponding developments in the works.

MVC can be further used for the observation of three-dimensional images without any aids. Here, the sense of depth is created by autostereoscopy.
