An interactive workshop gathering input from media and ICT stakeholders around the objectives of the new 3GPP study on Media Production over 5G Non-Public Networks.
| Date | 21 April 2021, 15:00–18:00 CEST |
| Location | Virtual event |
| Organizers | 5G-MAG |
Three sessions tackled different aspects of Media Production over 5G NPNs, with the final one organized as an interactive exchange. The main objectives of the workshop were:
- To collect input on the objectives of the Study Item from the media vertical around relevant media production use cases, media device and network orchestration solutions and other media-related aspects of Media Production use cases.
- To introduce relevant 5G System features coming from 3GPP and collect input around e.g. NPNs, Network Slicing, QoS classes, network event reporting and assistance, etc. that may be useful for media production.
- To facilitate collaboration and discussion around reference architectures for media production (including media and control flows), relevant QoS requirements and KPIs, protocols, codecs and service layers, etc.
Among the objectives of the new 3GPP study: how media production can beneficially use 5G systems; relevant network features (QoS classes, network slicing, network event reporting and assistance) and their usage within the media production environment; potential gaps in 3GPP specifications and the need for normative work; the AMWA NMOS orchestration framework and its applicability to 5G Systems; and the mapping of existing protocols onto 5G System delivery.
Speaker Sessions
5G-MAG: Where Media meets 5G — Ludovic Noblet, 5G-MAG CP-C Chair Slides · Video
Presented 5G-MAG's activities around media production over 5G Non-Public Networks and the opportunities to shape the technology ecosystem for local area media production and contribution scenarios, introducing the CP-C and CP-T working groups set up to discuss commercial/ecosystem and technology/architecture aspects respectively.
Introduction to 3GPP — Frédéric Gabin, 3GPP SA4 Chair Slides · Video
Introduced the activities of 3GPP SA4, the workgroup responsible for specifying codecs for speech, audio, video, graphics and other media types, as well as system and delivery aspects of such content. Announced the new NPN4AVProd (Feasibility Study on Media Production over 5G NPN) work item, active until Q1/2022.
Media Production requirements (AVPROD and VIAPA) — Ian Wagdin, 3GPP Rapporteur VIAPA, 5G-MAG CP-T Chair Slides · Video
Introduced the different types of production in terms of preparation, resources, obligations and workflows, distinguishing three tiers from more to less demanding scenarios. Covered the prior 3GPP SA1 study on Audiovisual Production (AVProd) use cases (TR 22.827) and the requirements captured in VIAPA — Video, Imaging and Audio for Professional Applications (TR 22.263).
What is a 5G Non-Public Network? — Peter Hedman, 3GPP Rapporteur eNPN Slides · Video
Presented 3GPP's work on Non-Public Networks (Rel-16 and Rel-17), addressing the needs of vertical industries with networks tailored for enterprise users with limited geographical coverage. Compared the two supported architecture models — Public network integrated NPN (PNI-NPN) and Stand-alone NPN (SNPN) — and covered authentication, VIAPA requirements, IMS voice/emergency services and UE onboarding.
SA4 Study Item on "Media Production over 5G NPN" — Thorsten Lohmar, 3GPP Rapporteur NPN4AVProd Slides · Video
Introduced the new study (Q2/2021 to Q1/2022) covering the use of 5G NPN systems for media production as part of an emerging ecosystem of connected equipment (IP cameras, displays, etc.). Focused on protocols and tools across scenarios — including ST 2110, NDI, SRT, RIST — and beneficial network features such as slicing, QoS classes/separation, and network event reporting and assistance.
The technology landscape and the transition towards IP — Peter Brightwell, BBC Slides · Video
Presented the technology landscape and transition towards IP, highlighting manufacturer fragmentation and the technical challenges of migrating to IP and software across media transport, automation, security, timing-sync, discovery, resilience, configuration, control, signaling and monitoring. Covered RTP transport standards, transport timing standards, video compression, and audio/streaming approaches, plus AMWA NMOS and other device control protocols.
Interactive Sessions
The speaker sessions were followed by three interactive sessions covering use cases for tier one and two production (sports, music and large-area deployments), tier three events (news-gathering and small-scale deployments), and audio production and audio networks. Questionnaires were used to collect feedback for 5G-MAG's internal work.
- 5G NPNs for Tier 1/2 Events: Sports, Music and large-scale deployments — moderated by Ian Wagdin and Thorsten Lohmar. Session Questionnaire
- 5G NPNs for Tier 3 Events: News-gathering and small-scale deployments — moderated by Morten Brandstrup and Thorsten Lohmar. Slides · Session Questionnaire
- Audio Production and Audio Networks — moderated by Maria Dolores Perez and Thorsten Lohmar. Slides · Session Questionnaire
