17 May 2013 Global View and Depth (GVD) format for FTV/3DTV
Author Affiliations +
FTV (Free-viewpoint Television) is 3DTV with infinite number of views and ranked as the top of visual media. It enables to view a 3D world by freely changing the viewpoint. MPEG has been promoting the international standardization of FTV since 2001. The first phase of FTV is MVC (Multi-view Video Coding) and the second phase of FTV is 3DV (3D Video). MVC completed in 2009 encodes multiple camera views efficiently and has been adopted by Blu-ray 3D. 3DV is a standard that targets serving a variety of 3D displays and is currently in progress. 3DV employs MVD (Multi-View and Depth) for data format. MVD is a set of views and depths at various viewpoints. 3DV sends MVD data at a few viewpoints and synthesizes many views at other viewpoints to be displayed on various types of multi-view displays at the receiver side. The 3DV activity moved to the Joint Collaborative Team on 3D Video Coding Extension Development (JCT-3V) of MPEG and ITU in July 2012. We propose GVD (Global View and Depth) as an alternative data format. GVD consists of base view, base depth, residual views and residual depths. GVD is a compact 3D expression compared to MVD since redundancy of MVD is removed in GVD. GVD has been accepted in JCT-3V.
