3GPP TR 26.805 "Study on Media Production over 5G NPN Systems" completed
With Thorsten Lohmar (Ericsson) as rapporteur, 3GPP Technical Report 26.805 comprises a variety of relevant media production use cases, reference media production architectures and workflow descriptions to identify standardization needs and potential standards gaps when using 5G Systems for media production including Non-Public Networks (NPN) both Standalone NPN and Public-Network-Integrated NPN.
Aspects such 5G System features, relevant protocols used in media production, codecs and service layers for 5G System usage, among others, are addressed in the document.

Aspects such as relevant media production use cases, reference media production architectures, relevant QoS requirements for media production workflows, 5G System features, protocols, codecs and service layers for 5G System usage, among others, are addressed in the document.
The document also contains guidelines for media producers and device manufacturers. In particular, the following are highlighted:
Avoid multiplexing of different media components (e.g. MPEG 2 Transport Stream). However, when MPEG-2 Transport Stream is used, then the following suggestions should be considered:
Allow extra jitter buffer for PCR timeline
Do not insert null packets
Encapsulate MPEG-2 Transport Stream in an RTP session according to IETF RFC 2250
Use GBR QoS flows to carry constant bit rate streams
Use dynamic bit rate adaptation to avoid packet loss
Provision network QoS end-to-end
Use client-initiated control protocols to avoid problems with firewalls and NAT
Use unicast IP data flows in preference to multicast IP
Use precise time synchronisation
Use packed-based transmission for audio streams with a single parameter set
3GPP also recommends 5G-MAG to identify a follow-up on these guidelines to support media production device manufactures and media producers to leverage different 3GPP features for their purposes.
Beyond the individual contributions by 3GPP members, 5G-MAG organized several workshops to reach out to various media producers and device manufactures with respect to 5G network usage.
