Study on Media Production over 5G NPN Systems
The present document identifies standardization needs and potential standards gaps when using 5G Systems for media production. More specifically the following aspects are addressed in this document:
- To identify the relevant media production use cases (professional, semi-professional, production, contribution), based on existing use-cases from TR 22.827 as well as requirements from TS 22.263, that may benefit from 5G System functionalities. This includes collaboration use cases between media producers and 5G System operators.
- To develop one or several reference media production architectures and to map the variety of different media and control flows (such as uplink video, return video, tally, etc) involved in media production onto 5G System delivery components.
- To identify relevant QoS requirements for media production workflows, including required bit rates, loss rates, formats, latencies and jitter, and to identify their impact on the relevant KPIs for media production workflows (reliability, mean-time-between failure, service-level agreements, etc.).
- To identify relevant 5G System features like NPNs, Network Slicing, QoS classes, network event reporting and assistance, etc. that are useful for media production, and to clarify their usage for media production.
- To identify the suitability of existing media production content delivery protocols, codecs and service layers for 5G System usage, evaluate benefits and gaps, and recommend profiles or extensions in collaboration with organizations that develop and deploy existing protocols and codecs.
- To study media device and network orchestration solutions (such as AMWA NMOS), and their integration/interactions with the 5G exposure framework.
- To collaborate with relevant other 3GPP groups and external organizations (VSF, 5G-MAG, EBU, etc.) on media-related aspects of Media Production use cases.
- To identify potential normative work on media level for media production use cases in 5G Systems.
The document primarily focuses on the usage of 5G Systems including NPNs (both Standalone NPN and Public Network Integrated NPN).
