3D@SAT will review and investigate the potential of future 3D Multiview (MVV) / Free viewpoint Video (FVV) technologies, build up a simulation system for 3D services over satellite and disseminate its findings to relevant fora (e.g. DVB 3D-SM, DVB TM–AVC, ITU-T/VCEG, ISO/MPEG, SMPTE, 3D@Home etc.).
The objectives for this study are as follows:
The scope of the activity is to pave the way to a completely new satellite TV system with the creation of a format agnostic production framework, which is multi-target; capable of addressing disparate user terminals and displays’ spatial resolutions up to HD and Super HD, and assess the role and competitiveness of satellite based networks in this new TV system.
The impact on production, transmission (i.e. bandwidth demand), 3D rendering and display technologies will be analysed. The study will cover also aspects like scalability and compatibility, i.e. the coexistence of monoscopic, stereoscopic and 3D MVV/FTV technologies.
3D-Video enables new immersive application such as 3DTV, 3D movies, immersive events, surround video, public 3D theatres, and new forms of immersive video communication. Especially recent advances in 3D display technology and Hollywood’s commitment to produce 3D content have stimulated R&D as well as standardization initiatives in this area.
3D systems will become an important part of the entertainment industry, which is growing worldwide with rates between 5% and 20%. Even higher growth rates can be observed in the area of 3D cinema. These developments have of course an influence on the home market, because secondary distribution (DVD, Blu-ray) of movies has become an important market segment.
3D film, 3DTV, Free Viewpoint Video and Super HDTV require the recording, storage, transmission and display of much more pixels than traditional TV or film. This means, that 3DTV and other immersive video services such as Free Viewpoint Video (FVV) or Super HDTV require very high transmission rates, which exceed the capabilities of classical digital transmission media such as DVB-C, DVB-T or xDSL. Only satellites for Fibre to the Home systems are able to provide enough capacity for such new services. Therefore, this study is considering a technological area, which will become a key area in future data transmission systems.
In this project, a simulation system will be setup which is based on the integration of the SATEM software simulator and the application layer simulator of Fraunhofer HHI.
It will consist of a server containing off-line encoded multiple video + depth (MVD) streams, a channel simulator simulating the transmission chain, a decoder for decoding the MVD streams and a display adaptation unit, which will render the output formats for the mono, stereoscopic and auto stereoscopic displays.
The 3D@SAT project plan is as follows:
The project has finished all activities and a final review was held on July 1, 2010. The main outcomes of the project are as follows:
