Abstract
Three-dimensional television (3DTV) and free viewpoint television (FTV) are new types of media that expand the user experience beyond what is offered by traditional media. 3DTV offers a 3D depth impression of the observed scene, while FTV allows for an interactive selection of viewpoint and direction within a certain operating range. Both are not mutually exclusive. On the contrary, they can be combined within a single system, since they are both based on a suitable 3D scene representation format.
These formats integrate various types of data such as multi-view video, depth or disparity data or 3D mesh models. Additionally, associated data such as camera calibration information needs to be provided in order to establish 2D-3D correspondences. Efficient compression is a crucial point for the success of 3DTV and FTV applications.
The tutorial will give an overview of compression for 3DTV and FTV, including 3D mesh models, conventional stereo video, multi-view video, and depth or disparity data. Associated algorithms and systems for sender and receiver side 3D signal processing, as well as 3D and interactive display will be outlined as well. A special focus will be on available and emerging international standards as developed by ISO/MPEG and ITU/VCEG.
