3D IPTV  
A Potential Future (R)Evolution for Digital TV  
BELL LABS Research Project  
technology will be able to bring the best quality for a  
certain application and at which bandwidth?  
Context  
Digital television (IPTV), as we know it today is  
essentially little different from the former analog  
television. Nevertheless, the IPTV technology  
inherently offers a huge potential for growth in new  
services and personalization.

An other set of challeges are related to how  
applicatoins will be using the 3D technologies. How  
will 3D acquisition of the content happen? How will  
3D improve man-to-machine interfaces. What new  
opportunities will it bring for e.g. watching sport-  
events, gaming, video communication, ...  
Figure 1: Auto-stereoscopic 3D display  
Auto-stereoscopic 3D displays will be one of the  
technologies which will initiate a new era for digital  
television. This technology brings a new television  
experience, with a higher immersion of the viewer. In  
addition, it also opens new opportunities for natural  
user interfaces and new 3D services. During the  
demonstration one can get acquainted with this new  
technology, the underlying encoding methods, new  
applications, and research in this domain.  
Scenario & Innovations  
2D+Z coding technology  
With the 2D+Z coding technology, a very bandwidth-  
efficient mechanism is demonstrated for initial 3D  
IPTV deployments. The advantage of this technology  
is that it is backwards compatible with normal 2D  
displays, while providing a basic 3D experience with  
only 10%-20% overhead on the IP network  
Challenge  
Auto-stereoscopic 3D displays are expected to be the  
next technology wave after High Definition (HD)  
Television. Besides the high number of technology  
challenges needed to be solved on the screen-  
technology level (e.g. beter 3D resolution, bigger  
viewing angles, ....), there is an even bigger amount  
of challenges to be solved before the system will be  
ready for deployement in the same applications space  
where current 2D displays are being used.  
In order to make the 3D technololgies available to a  
large market such as residential IPTV, a high number  
of challenges needs to be tackled.  
Figure 3: 2D+Z coding technology  
A disadvantage of the technology is the very limited  
viewing angle, and visual artifacts in occluded areas.  
The most important technological challenge are new  
3D encoding technologies. H.264 AVC is a very mature  
technology for 2D. It brings high quality with low  
bandwith requirements. For 3D encoding, all options  
are still open, and it is not yet clear, which
