F.Live: Towards interactive live broadcast FTV experience

Free-viewpoint television (FTV) is a visionary application that provides immersive experience to the audience with the freedom of changing viewpoint during the video playout. However, live broadcasting and user interaction do not coexist in existing FTV systems. In this paper, we propose F.Live, a framework of FTV content dissemination that supports user-initiated viewpoint changing for live broadcasting. Simulation result of a large-scale experiment, based on camera array settings of existing Nagoya systems and EyeVision System, shows that F.Live is capable of supporting 100,000 concurrent audiences with free-viewpoint low user interaction latency and feasible bandwidth requirements.
