The talk summarizes work conducted by the author's group over the past five years and its context within the international standardization in ITU-T Study Group 12 and the Video Quality Experts Group (VQEG). First, the talk discusses subjective test methods for high-quality and immersive video, including sensory evaluation for analytic video-quality assessment, especially addressing high-quality content production, the assessment of the suitability of content for coding- and transmission-related quality assessment, subjective test methods for video-quality and a more holistic QoE evaluation including presence and simulator sickness, as well as considerations on user-behavior tracking. Further, the talk presents modelling approaches for the automatic prediction of different aspects of quality and QoE, primarily focusing on so-called parametric models suitable for a light-weight service quality monitoring. The talk concludes with an outlook on ongoing activities also within the standardization groups the author is involved with.

 

5G Opportunities for Content Production - Register Now

Date: December 9, 2020
Time: 12:00pm - 1:00pm ET
Presenter: Dr. Ing, Maria Dolores Perez Guirao, Spectrum & Innovation Manager, Research & Innovation, Sennheiser Electronic GmbH & Co. KG

 APWPT Foto DrPG

In the talk, Dr. Pérez Guirao summarizes the work conducted over the past two and a half years within 3GPP, EBU, and 5G-MAG working groups, for the development of 5G technology for content production.
First, Dr. Pérez Guirao discusses content production use cases and their potential requirements to 5G. Although most of the use cases discussed are already possible with existing technologies, they may see a successive migration to 5G as far as it is able to provide an added value (e.g. cost reduction, simplification of workflows, interoperability) to involved stakeholders. Further use cases, that may be first enabled by 5G, will also be discussed. Further, Dr. Pérez Guirao will resume the standardization activities initiated by the content production community in 3GPP Rel-17 as well as the 5G-MAG activities to accelerate standards development and adoption. To conclude the talk, Dr. Gómez Vaquero, as the project coordinator, will introduce the recently started 5G-RECORDS (https://5g-ppp.eu/5g-records/) project, an EU funded project which for the very first time brings together at a large scale the content production (PMSE) sector with the telecom sector.

Activity of Disseminating Japanese EWBS Technology

Presenter: Yasuji Sakaguchi   Co-Authors: Yasuo Takahashi & Seiji Sakuma

SAKAGUCHI Photo 2Takahashi PhotoSakuma

The Japanese digital terrestrial broadcasting system (ISDB-T) is adopted by 14 countries in Latin America. DiBEG extends technical support and cooperation to help the implementation of ISDB-T in those countries. EWBS (Emergency Warning Broadcast System) is one of the particular features of ISDB-T and expected to be introduced as a national communication system in case of emergency. The “EWBS Superimpose Dissemination System”, improved from the Japanese original version by adapting to local requirements in Latin America, has successfully been developed in Japan. Taking advantage of the robustness of the ISDB-T “One-seg” technology, making maximum use of the existing broadcasting network, this system realizes simple utilization and wide coverage with outstanding reliability. This system has already been introduced to some Latin American countries and highly evaluated. Japan continues technical cooperation so that EWBS can contribute to disaster prevention and mitigation in these ISDB-T adopting countries.

 

5G Opportunities For Media Distribution

Presenter: Dr. Jordi J. Gimenez, Project Manager, 5G-MAG

Jordi

3GPP technologies are being shaped to accommodate features and functionalities demanded by the media industry. Originally driven by the needs of mobile networks to accommodate the increasing consumption of multimedia content, the scope has broadened to offer solutions to different stakeholders - including media service providers, CDN providers, network operators - for the distribution of services to the end users. Enhancements to 5G include features to improve its ability to distribute media content and services, not only using unicast but also relying on multicast or broadcast, edge caching, virtualized media functions, network slicing or even the potential of using both terrestrial and satellite networks. A wide set of options that may create the framework for enhancing IP-based distribution of media content to users.

 

Network Resource Allocation System for QoE-Aware Delivery of Media Services in 5G Networks

Presenter: Roberto Viola, Research Associate at Digita Media Department, Vicomtech Foundation, Basque Research and Technology alliance (BRTA)

378 rviola mod 

The explosion in the variety and volume of video services makes bandwidth and latency performance of networks more critical to the user experience.  To cope with the traffic demand and content provider's service level agreement (SLA), 5G telecommunication networks are expected to outperform current networks in terms of keyperformance indicators (KPIs).  Machine Learning (ML), Software Defined Network (SDN) and Network Function Virtualization (NFV) are key technologies to enable dynamic network setup in 5G networks.  The webinar will overview these technologies and show results of a Network Resource Allocation System which exploits real time captured metrics to manage the network topology through the SDN Controller.

Viable Deterministic 5G System Model

Presenter: Ling Ling Sun, Assistant General Manager Technology/Chief Technology Officer of NET (Nebraska's PBS & NPR Stations)

Ling Ling Sun 2

Recently, there are increasing studies in deterministic 5G, in both academia and industry. It is stated that “5G deterministic network is based on Cloud-Native and distributed architecture, leveraging key technologies such as heterogeneous MEC and dynamic intelligent Network Slicing, to meet differentiated network requirements and deterministic SLA commitments through a single cloud, enabling thousands of industries” (Jacqueline Shi, MWC, Shanghai, June, 2019).  However, a viable system model is lacking to conceptually summarize key features of deterministic 5G network. Viable system model (VSM) for organization has been utilized to manage networking complexity (Ling Ling Sun, Jun 17, 2019, TVTechnology).

It will also discuss more details into the two different HDR transfer functions available today PQ and HLG and their benefits and applications to different markets. The 4K HDR workflow from camera capture to distribution will also be discussed and the different standards available today both open and proprietary will be described.  From the display side the process of Display Mapping will be explained. Proper Display Mapping manages to maintain creative intent even if the color gamut and luminance range of the content is wider than the display’s capabilities.

 

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

jordi pic

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.
