Performance Evaluation of ATSC 3.0 DASH Over LTE eMBMS

Ultra High Definition (UHD) video streaming to portable devices has become topical. Two standardized codecs are current, H.264/Advanced Video Coding (AVC) and the more recent High Efficiency Video Coding (HEVC). This paper compares the two codecs' robustness to packet loss, after making allowances for relative coding gain. A significant finding from the comparison is that the H.264/AVC codec is less impacted by packet loss than HEVC, despite their differing coding efficiencies and including at low levels of packet loss. The results will be especially relevant to those designing portable devices with 4K UHD video display capability, allowing them to estimate the level of error concealment necessary. The paper also includes the results of HEVC compressed UHD video streaming over an IEEE 802.11ad wireless link operating at 60 GHz as a pointer to future performance in an error-prone channel.

Driven by the most advanced technologies, such as massive multiple-input multiple-output (MIMO), 3D beamforming, Software-Defined Networking, and network slicing, 5G/6G systems support radio connections and end-to-end network connectivity at ultrahigh speeds, low latency, high reliability, and massive connectivity. 5G/6G networks promise a faster, more streamlined future for broadcasters. It can handle rapid changes, along with improved quality standards in broadcasting. However, broadcasting services are becoming increasingly distributed and prevalent; thus, how to effectively provide broadcast services to end users has recently become a natural concern. In this paper, we propose a novel concept of Beamforming-as-a-Service (BFaaS) for delivering multicast and broadcast services in 5G/6G networks. We first comprehensively overview and study background standards and industrial activities through broadcast projects that have been carried over 5G platforms. Then, we shed light on the requirements of providing multicast and broadcast services to end users and the importance of beamforming in delivering multicast and broadcast services in 5G/6G networks. From this point, we define the BFaaS concept and vision and the benefits of the proposed BFaaS scheme. Next, we discuss the beam generation process, beamforming control and the channel model which is used in the proposed system model analysis. As a step further, with the proposed system model, we propose optimal algorithms for allocating beams to different service areas. The simulation results demonstrated the effectiveness of the proposed BFaaS scheme. Finally, we summarize the paper by identifying the potential areas of application of BFaaS for future research directions.INDEX TERMS 5G networks, terrestrial broadcasting, broadband, multicast and broadcast services, new radio, as-a-service, beamforming.NGUYEN HUU TRUNG received the Dipl.Eng., M.E., and Ph.D. degrees from the
