ATTEST Technical Approach
In ATTEST the need for the 3D video content will be satisfied in two different
ways:
•
A range camera will be converted into a broadcast 3D camera, which
requires a redesign of the camera optics and electronics to deliver a full
resolution 3D camera, higher depth and pixel resolution;
•
As the need for 3D content can only partially be satisfied by newly recorded
material, ATTEST will also develop algorithms to convert existing 2D video
material into 3D. Both offline (content provider) and online (set-top-box)
conversion tools will be provided.
In the introduction period, 2D and 3D-TV sets will co-exist. ATTEST will,
therefore, develop coding schemes within the current MPEG-2 broadcast
standards that allow transmission of depth information in an enhancement layer,
while providing full compatibility with existing 2D decoders. First, perceptual
quality will be assessed through a software prototype, later a hardware real-time
decoder prototype will be developed.
At present, a suitable glasses-free 3D-TV display that enables free positioning
of the viewer is not available. Also, there is no suitable display for single users
(3D-TV on PC), or for use in a typical living room environment. ATTEST will
develop two 3D displays (single and multiple user) that allow free positioning
within an opening angle of 60 degrees. Both are based on head tracking and
project the appropriate views into the viewer's eyes.
ATTEST will deliver a 3D-TV application running on a demonstrator platform,
with an end-to-end DVB delivery system. The 3D content will either be recorded
with the ATTEST 3D camera, or will be converted from 2D video footage using
the ATTEST 2D-to-3D conversion tools. ATTEST will build a real-time MPEG-
2 base and 3D enhancement layer decoder and demonstrate optimized 3D video
rendering on the ATTEST single and multi-user 3D displays.
VISICAST
The goal of
ViSiCAST: Virtual Signing: Capture, Animation, Storage &
Transmission
project (IST VISICAST) is to improve the quality of life of
Europe's deaf citizens by widening their access to services and facilities enjoyed
by the community at large. The project identifies a number of aspects of life
where the integration of deaf individuals in society would be improved if sign
language communication was available: access to public services, commercial
