The 3DAV group of MPEG covers the extensions needed for a successful 3D audio and video support. 10–12 In this section an overview of the status of coding and 38 Chapter 3 compression of input data related to different 3D capturing modes is provided. 1. Simply, it is a special case of multiview video with the number of views equal to two. , there is a high level of redundancy between the two images, compression of such pairs is quite successful. Therefore, in addition to the temporal redundancy that prevails between consecutive frames, now there is additional redundancy between the two parallel video streams that represent the right- and left-eye views.

Horizontal-parallax-only multiview systems also get closer to ideal light-field-rendering devices as the number of views increases, but only along the horizontal direction. The practical problems associated with integral imaging are also severe. The alignment problem is still present but somewhat eased if the same microlens array is used during recording and display. However, this is impossible if an integral-imaging-based TV system is launched. The resolution problem is immensely more severe since the number of views is now much larger; instead of a 1D (horizontal) array, a 2D array of elemental images must be blended.
