  Sharing live telepresence experiences for teleconferencing or remote
collaboration receives increasing interest with the recent progress in
capturing and AR/VR technology. Whereas impressive telepresence systems have
been proposed on top of on-the-fly scene capture, data transmission and
visualization, these systems are restricted to the immersion of single or up to
a low number of users into the respective scenarios. In this paper, we direct
our attention on immersing significantly larger groups of people into
live-captured scenes as required in education, entertainment or collaboration
scenarios. For this purpose, rather than abandoning previous approaches, we
present a range of optimizations of the involved reconstruction and streaming
components that allow the immersion of a group of more than 24 users within the
same scene - which is about a factor of 6 higher than in previous work -
without introducing further latency or changing the involved consumer hardware
setup. We demonstrate that our optimized system is capable of generating
high-quality scene reconstructions as well as providing an immersive viewing
experience to a large group of people within these live-captured scenes.
