An overview of available and emerging 3D video formats and depth enhanced stereo as efficient generic solution

Recently, popularity of 3D video has been growing significantly and it may turn into a home user mass market in the near future. However, diversity of 3D video content formats is still hampering wide success. An overview of available and emerging 3D video formats and standards is given, which are mostly related to specific types of applications and 3D displays. This includes conventional stereo video, multiview video, video plus depth, multiview video plus depth and layered depth video. Features and limitations are explained. Finally, depth enhanced stereo (DES) is introduced as a flexible, generic, and efficient 3D video format that can unify all others and serve as universal 3D video format in the future.
