ABSTRACT
3D tele-immersion improves the state of collaboration among geographically distributed participants. Unlike the traditional 2D videos, a 3D tele-immersive system employs multiple 3D cameras based in each physical site to cover a much larger field of view, generating a very large amount of stream data. One of the major challenges is how to efficiently transmit these bulky 3D streaming data to bandwidth-constrained sites. In this paper, we propose an adaptive Human Visual System (HVS) -aware bandwidth management framework for efficient delivery of multiple streams produced from distributed 3D tele-immersive sites to a receiver site with limited bandwidth budget. Our novel adaptation framework exploits the semantics link of HVS with multiple 3D streams in the 3D tele-immersive environment. Our evaluation results show that the proposed HVS-aware adaptation improves the total quality per unit of bandwidth used to deliver streams in 3D tele-immersive systems.
