Date: September 29, 2021
Time: 10:00AM - 11:00PM EST
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).

How do we measure the greenhouse gas emissions of broadcasting
Presenter: Jigna Chandaria, Lead Research Engineer, BBC R & D
Tackling climate change requires every industry to play its part. But how do we measure the environmental impact of broadcasting? How could this footprint change due to new technologies, changes in audience behaviour or demographics? This talk introduces a method for modelling the energy use and greenhouse gas emissions of media services and shows the results when applied to BBC TV and radio services. 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.

5G New Radio for Terrestrial Broadcast A Forward-Looking Approach for NR-MBMS
- Presented by Dr. Jordi J. Gimenez, Research Engineer, Funksysteme/Radio Systems 3GPP
The configuration of 5G-NR (New Radio) carriers in order to convey terrestrial broadcast services that can be delivered by the 5G system according to requirements defined by broadcasters and received free-to-air (in a receive-only mode) by users. The discussion goes beyond the recent developments in 3GPP around LTE-based 5G Terrestrial Broadcast (also known as FeMBMS) as it considers the possibility of implanting a 5G Broadcast system fully integrated with 5G-NR and 5GS, avoiding the inefficient legacy from LTE at the RAN. This leads to a less complex architecture fully embedded with the recent developments around 5G but also with drawbacks such as limited SFN support to avoid deviating from unicast numerologies. The solution is applicable to cellular networks and also traditional broadcast infrastructure.
