Traditional TV program and the free-viewpoint 3DTI (3D Tele-immersion) stand in the two extremes of broadcasting services. While the former consumes much less bandwidth due to its content uniformity, the latter grant the freedom of audience-initiated view changing without the intervention of cameramen and program producers. Standing at an equilibrium point of this tradeoff, we propose the 3DTI Amphitheater, a virtual environment which magnifies the effectiveness of content sharing in the P2P delivery network while preserving the semi-free view experience.
