  The rise of capturing systems for objects and scenes in 3D with increased
fidelity and immersion has led to the popularity of volumetric video contents
that can be seen from any position and angle in 6 degrees of freedom
navigation. Such contents need large volumes of data to accurately represent
the real world. Thus, novel optimization solutions and delivery systems are
needed to enable volumetric video streaming over bandwidth-limited networks. In
this chapter, we discuss theoretical approaches to volumetric video streaming
optimization, through compression solutions, as well as network and user
adaptation, for high-end and low-powered devices. Moreover, we present an
overview of existing end-to-end systems, and we point to the future of
volumetric video streaming.
