3D video technology is already in the market with stereoscopic systems
• Television sets
• Blu-Ray Disc players
• highly motivated by the success of 3D movies in the theaters:
• brings a new visual experience to viewers
This presentation shows current technical efforts to bring 3DTV signals to the homes by the free-to-air terrestrial digital television system.

INTRODUCTION
Plano-stereoscopic imaging systems deliver two images
(left and right) that are arranged to be seen
simultaneously, or near simultaneously, by the left and
right eyes.

INTRODUCTION
Viewers perceive increased depth in the picture, which
becomes more like the natural binocular viewing
experience.
Since 2010 many 3DTV capable consumer products
have been launched in the market.

Issue's Demo
How to use current 3D capable TVs in the market?
What happens if we change from a 3D content to a non-3D one?
Let's check these out in practice.

DVB-3DTV
Specification of methods to encode and deliver DVB frame compatible Plano-stereoscopic 3DTV services over conventional HDTV broadcast infrastructures;
Selection 3DTV formats;
Definition 3DTV service signaling information;
Handling of graphics and captions overlays in the receiver during the reception 3DTV service.

DVB-3DTV Graphics Signaling
Graphics and subtitles over 3DTV need to be positioned harmoniously within the three-dimensional scene
The depth information can be expressed in terms of disparity
A new segment, Disparity Signaling Segment (DSS), was added to DVB subtitling systems

• Video-Plus-Depth representation.• Video uses conventional MPEG-2 approach. • The depth of a sequence is a side information
OUR RESEARCH GROUP
3DTV Transmission AspectsCelso Kurashima / Adenilson Tomé / Raoni Lourenço
Research topics of interest:
•Digital Television (SBTVD mainly)
•3D-TV related:
• Free Viewpoint Video - FVV and FTV
•Immersive communications related:
• Large visual image/graphics – e.g. 4K, panoramic, etc.
• Multi-projection / Multiple camera systems
• Telepresence
OUR RESEARCH GROUP
3DTV Transmission AspectsCelso Kurashima / Adenilson Tomé / Raoni Lourenço
Study of techniques for insertion of 3D video signals in SBTVD – current master project:
•Transmission of Stereoscopic 3D Video in SBTVD, Scalable Video Coding (SVC) and Multi View Video Coding (MVC).
CONCLUSION
Questions for future of SBTVD:Adoption of DVB-3DTV Signaling for SBTVD is simple.
Is it enough to accept this approach purely?
Shouldn't we start working with new codecs directly?
