A Potential Future (R)Evolution for Digital TV
BELL LABS Research Project
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.
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.
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
technology will be able to bring the best quality for a certain application and at which bandwidth?

Scenario & Innovations
2D+Z coding technology
With the 2D+Z coding technology, a very bandwidthefficient 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

A disadvantage of the technology is the very limited viewing angle, and visual artifacts in occluded areas.
The 3th dimention will bring new opportunities for advanced user interfaces. New ways of representing information and browsing through content, enabled with personalizations will give the user a better control to sellect the right video content out of the huge amount of data both on

The ultimate goal is to come to a real
During sport events the user will be able to select his own viewing position and be able to replay crucial scenes from any angle they want.
BENEFIT: 3D TVs will be one of the technologies which would 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.

Telle que nous la connaissons actuellement, la télévision par Internet (IPTV) présente peu de différences avec la télévision analogique. Cependant, la technologie IPTV possède intrinsèquement un potentiel de croissance immense en matière de nouveaux services et de personnalisation. Les écrans 3D
