ABSTRACT
This paper examines the protocol structure of ATSC 3.0, the next-generation terrestrial broadcasting standard, and explains in-depth the technology of Real-Time Object Delivery over Unidirectional Transport (ROUTE) and MPEG Dynamic Adaptive Streaming over HTTP (DASH). Specifically, it considers both low and service signaling methodologies of ROUTE/DASH, that enable immersive media, stereoscopic 3D, and 360 virtual reality (VR), delivery in ATSC 3.0. Furthermore, this paper also provides the signaling examples to give readers new perspectives on immersive broadcasting through ROUTE/DASH in ATSC 3.0. In the era of COVID-19 pandemics, this kind of type, the ATSC 3.0 immersive media service method is expected to become an alternative to performance and media consumption in the future.
