Abstract
3D Tele-Immersion (3DTI) system brings 3D data of people
from geographically distributed locations into the same virtual
space to enable interaction in 3D space. One main obstacle
of designing 3DTI system is to overcome its high bandwidth
requirement when disseminating the 3D data over the
network. In this work, we present a novel compression and
dissemination framework to reduce the bandwidth usage.
The main idea is to decompose the 3D scene into seperable
objects and schedule the dissemination of each object
independent of each other based on the object's importance
to the quality of experience. Through real implementation
on the 3DTI testbed, our framework is shown to reduce the
bandwidth usage by 30% to 50% with reasonable degradation
of visual quality.
