Point Cloud Video Streaming: Challenges and Solutions

Volumetric video (or hologram video), the medium for representing natural content in VR/AR/MR, is presumably next generation of technology and a typical use case 5G beyond wireless communications. To realize volumetric applications, efficient streaming critical demand. This article responds to challenges proposes solutions transmission systems point cloud video, which most popular favored way represent media significantly differs from other types videos. In particular, we first introduce its then discuss streaming, including encoding, tiling, viewing angle prediction, decoding, quality assessment optimization. Furthermore, explain prototype MPEG DASH-based system as preliminary study, along with more simulation results verify performance. Finally, identify future research directions providing high-quality streaming.
