ATSC 3.0 ROUTE/DASH Signaling for Immersive Media: New Perspectives and Examples

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.

Effects on Long-Range Dependence and Multifractality in Temporal Resolution Recovery of High Frame Rate HEVC Compressed Content

“…HFR can be described as video content captured or displayed at a frame rate of 60 fps or higher. This is in contrast to the SFR/LFR that is typically used for television [5,6]. Besides the realistic experience which is tied to the perception of motion, HFR reduces motion blur when an object is moving and enables its clearer representation, described as smooth motion given in more detail.…”

“…The scenario of typical TRR found in practice includes temporal filtering, followed by temporal resolution matching. Significant savings in memory and channel capacity can be probably temporarily made in the temporal domain by decreasing frame frequency, and this is called temporal filtering [5,6]. Frame frequency alignment leads to HFR TRR.…”

“…Moreover, in the Advanced Television Systems Committee (ATSC) 3.0 ecosystem, high or very high frame rates are expected, as well as video services developed by interconnecting 5G communication networks and ATSC 3.0 broadcasting. Currently, in these cases, high-efficiency video coding (HEVC or H.265) is adopted to deal with novel video technology formats like HFR [4][5][6]. Progressive formats are accompanied by picture rates with possible dealing with SFR and HFR (like 120 fps) recovery and temporal filtering [5,6].…”

Media over Internet Protocol (IP) provides a high level of flexibility, and new broadcast systems are already using IP infrastructures [7].…”

“…The infrastructures enable HFR distribution, but dealing with video in such manner also leads to significant changes in bandwidth requirements. Besides future formats and services, compression technologies are of crucial interest [6]. The perceptual quality improvement resulting from HFR is recognized in industrial and academic communities [8].…”
