  FVV Live is a novel end-to-end free-viewpoint video system, designed for low
cost and real-time operation, based on off-the-shelf components. The system has
been designed to yield high-quality free-viewpoint video using consumer-grade
cameras and hardware, which enables low deployment costs and easy installation
for immersive event-broadcasting or videoconferencing.
  The paper describes the architecture of the system, including acquisition and
encoding of multiview plus depth data in several capture servers and virtual
view synthesis on an edge server. All the blocks of the system have been
designed to overcome the limitations imposed by hardware and network, which
impact directly on the accuracy of depth data and thus on the quality of
virtual view synthesis. The design of FVV Live allows for an arbitrary number
of cameras and capture servers, and the results presented in this paper
correspond to an implementation with nine stereo-based depth cameras.
  FVV Live presents low motion-to-photon and end-to-end delays, which enables
seamless free-viewpoint navigation and bilateral immersive communications.
Moreover, the visual quality of FVV Live has been assessed through subjective
assessment with satisfactory results, and additional comparative tests show
that it is preferred over state-of-the-art DIBR alternatives.
