Feasibility Analysis for Audiovisual Production over 5G

LTE-based 5G Terrestrial Broadcast allows to deliver linear content to mobile and portable devices (i.e. smartphones, tablets and vehicles) in a cost efficient way to wide areas, in compliance with the requirements of media companies, i.e. high QoS, free-to-air delivery, …, by means of High Power High Tower (HPHT) networks as well as Low Power Low Tower (LPLT) ones. This possibility opens the way to new synergies and different collaborative scenarios between the broadcast and mobile ecosystem technologies.

5G-MAG members have identified a series of technical features in the 5G specifications applicable to audiovisual production scenarios (see CPT0046). This WI focuses on how such features defined in 3GPP specifications (Release 17 with an outlook on Release 18) can be implemented and configured in a real deployment, the description of the architecture and deployment models and gap analyses with regards to the identified KPIs, requirements and expectations. Any identified gaps may be fed back to 3GPP in the form of member contributions. The principal topics covered by this WI are the following:

  • Device (UE) on-boarding and provisioning for 5G NPNs

  • Support of Time Sensitive Communications in 5G Systems

  • Interworking between 3GPP (NR) and non-3GPP access

  • Media Streaming architecture for Uplink Streaming applications

  • Architecture enablers for Edge computing applications

  • Support of low-latency applications in 5G networks

Emergency Alerts based on LTE-based 5G Terrestrial Broadcast 

Emergency alert systems are crucial elements to reach out to the population before, during and after an emergency, crisis, or catastrophe. In principle, both broadcast and mobile networks can be used to convey messages and relevant information. However, there is a difference between the two infrastructures in terms of their fail-safety. Broadcast networks based on high-power-high-tower stations to some extent make use of diesel engines to produce electrical power which allows the corresponding transmitters remaining operational for days or even weeks after electricity blackout. Mobile networks are typically deployed with batteries which may not hold up to lengthy electricity outages.

Non-Public Networks in Media Production

Non-Public Networks (NPNs) are a feature of 5G technology designed for localized non-public use. For media organizations, NPNs may offer the possibility of deploying fixed and nomadic networks, where fixed networks would cover small areas like studios or extend to the entire premises as a so-called campus network. NPNs offer a variety of deployment configurations and options. Depending on the requirements of media organizations and the type of production or contribution scenario, stand-alone NPNs or NPNs with varying degrees of integration with public networks may be considered.

5G Multicast and Broadcast Services

This work item deals with the distribution of linear content over 5G networks focusing in particular on 5G Multicast Broadcast Service and related 3GPP work items. This WI investigates the technical features and deployment options applicable to MBS and their application to current and future distribution requirements from service providers.

Linear and On-Demand Media Streaming

This work item deals with the distribution of linear and on-demand content over 5G networks focusing in particular on the 5G Media Streaming Architecture and related 3GPP work items. This WI investigates the different commercial arrangements and deployment options applicable to managed and un-managed (OTT) content distribution and their application to current and future distribution requirements from service providers.

Media distribution over 5G mobile networks

Media content is increasingly being delivered via fixed line and mobile IP networks. This WI is based on the hypothesis that in the future all media content (e.g. linear/live and on-demand) will be delivered via IP-based networks. Audiences on the move will consume media on a range of mobile devices (e.g., smartphones and tablets), as well as in connected cars. This work item focuses on the distribution of content over all-IP 5G mobile networks.
