Serverless Streaming for Emerging Media: Towards 5G Network-driven Cost Optimization


Immersive 3D media is an emerging type of media that captures, encodes and reconstructs the 3D appearance of people and objects, with applications in tele-presence, teleconference, entertainment, gaming and other fields. In this paper, we discuss a novel concept of live 3D immersive media streaming in a serverless setting. In particular, we present a novel network-centric adaptive streaming framework which deviates from the traditional client-based adaptive streaming used in 2D video. In our framework the decisions for the production of the transcoding profiles are taken in a centralized manner, by considering consumer metrics vs provisioning costs and inferring the expected consumer quality of experience and behavior based on them. In addition, we demonstrate that a naive application of the serverless paradigm might be sub-optimal under some common immersive 3D media scenarios.
