An Introduction to 3GPP 5G Multicast and Broadcast Services

Presenter: Dr. David Vargas, Senior Research Engineer at BBC, working on 5G technologies for media distribution

3GPP Release-17 is standardizing in the 5G system using NR the support of general multicast and broadcast communication services such as: transparent IPv4/IPv6 multicast delivery, IPTV, software delivery over wireless, group communications and IoT applications, V2X applications, and public safety. 5G Multicast and Broadcast Services (MBS) is a point-to-multipoint service that can improve the network efficiency and user experience when transmitting the same content to multiple users. The design principle of 5G MBS is to minimise the implementation impact of the feature by reusing as much as possible 5G unicast architecture and functions. In this talk, Dr. Vargas will introduce use cases, design principles and functionality of 5G MBS with a focus on the standardization of the Radio Access Network. Finally, this talk will also present potential new features for MBS currently under discussion in 3GPP for the next Release-18, which will be the first release of 5G-Advanced.

Quality of Experience Models and Methods for Broadcasting

Presenter: Maurizio Murroni, Associate professor of Telecommunications at the Department of Electrical and Electronic Engineering (DIEE) of the University of Cagliari

During the last decade, the evolution of the TV market has been terrific. Broadcasters have been facing new challenges to cope with an increasing demand for new services from the user's side. With the convergence of second-screen adoption and the abundance of real-time news consumption via social channels, the broadcast landscape underwent a major transformation. Viewers have begun to demand highly customized experiences that meet their individual needs. In short, the evolving wants and needs of the viewer seem to be in the future of broadcast television. In the next few years, it is likely that this will become even more evident, with more people demanding customized television experiences through user-generated content and the option of micro bundled packages. To keep up, broadcasters must stay current with the latest innovations to engage with their customers.

To this end, there is a need to evaluate the level of enhancement of these experiences and to compare their functionalities and requirements so operators can properly design their networks and regulators can assess the services offered to the audience. This lecture will overview the state-of-the-art quality of experience (QoE) models and methods with a focus on broadcasting applications. The concept of QoE will be introduced first. Methods for the QoE assessment based on ITU Recommendations for test methodologies will be presented. Models and metrics for QoE will be then detailed. Future trends and challenges ahead on QoE for broadcasting will be announced. The talk will be a tutorial session and the audience is expected to have basic knowledge of multimedia systems and signal processing (BsC students in their final year, MsC students and PhDs).

Broadcasting: the past and the future in a connected world

Presenter: Peter Siebert, Broadcast Industry Advisor & Madeleine Noland, President of ATSC

The first television broadcasts around the world started more than ninety years ago, turning quickly into the preferred medium for media entertainment at home, replacing radio and movies. Those were hectic days for the broadcasting engineers facing daunting challenges day in and day out to satisfy the growing audience demands. Since those first decades, the broadcasting industry has fostered many cutting-edge technologies related to all the fields involved in a communications system implementation such as planning, channel coding, video coding, and wireless transmission, to name a few.

Standardization is a necessary precondition for the success of any technology that relies on interoperability among multiple diverse systems.  Without these specifications in place the broadcast and consumer industry as we know it today would not be possible.  Television and broadcast have come a long way, and Standards Development Organizations (SDOs) must stay ahead of the marketplace needs. We advanced from black and white to color, from analogue to digital broadcast, and now with the rise of mobile devices, streaming services, 5G and more, broadcasting must again move forward to meet the changing landscape. How will we consume media in the future? Will we still receive information and entertainment via terrestrial, satellite or cable broadcast? How are these systems evolving to bring the most value to businesses and consumers? How are SDOs leading the transformation?

In this webinar, you will have the opportunity to hear from two of the main players in standards development on recent advances in the broadcast industry: Madeleine Noland, current president of ATSC, and Peter Siebert former Executive Director of the DVB project. They will discuss the importance of the standardization process in an international and connected landscape, the main contributions of broadcasting to the data/media delivery in current affairs, the role of terrestrial broadcasting in a mobile, on-demand world, and the future prospective of broadcasting. In addition you will learn about the relevance of standards for the industry and insights on standards development.

This IEEE BTS webinar is a University and Industry exchange.  A conversation highlighting challenges and benefits;  discussing technology, applications, market demands and standardization. As the broadcasting industry continues to evolve at an incredible pace, it generates new challenges and opportunities.  Discover your career in the future of broadcasting.

It explores the use of scenario modelling to help us understand the effect of changes on the whole system.

Immersive, Interactive Audio Experiences with Audio Orchestrator

Presenter: Jon Francombe & Kristian Hentschel BBC R & D

Device orchestration is the concept of delivering a media experience using a set of connected devices. The Audio Team at BBC R&D have been investigating this technique for delivering immersive and interactive audio-visual experiences. Following work on perceptual evaluation and use case scoping, we designed and released a production tool for rapid prototyping of orchestrated audio experiences. Audio Orchestrator is used to author metadata that ensures that audio objects are appropriately routed and that the resulting experience can adapt to the number and types of available devices. The output of the process is a customisable web application that handles the technicalities of orchestration (synchronisation, device pairing, and audio delivery). The tool is freely available for non-commercial use from the BBC MakerBox platform. Support is provided on a community forum, and full online documentation is available. Since its release in summer 2020, Audio Orchestrator has been used to create a number of trial productions, including audio drama (Decameron Nights, Monster), music (Pick A Part with the BBC Philharmonic) and sport (a Six Nations rugby highlights package). These have been viewed over 10,000 times on the BBC Taster website. In this talk, we'll introduce the technology, demonstrate the Audio Orchestrator workflow, and describe the trial productions.
