3GPP Study on Media Production over 5G NPN completed

3GPP completes Technical Report on Media Production over 5G Non-Public Network (NPN) Systems

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:

  1. Allow extra jitter buffer for PCR timeline

  2. Do not insert null packets

  3. 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.
