WI: "Advanced Media Services" over 5G

4G is well-known for being able to distribute traditional video services primarily to smartphones, and to some extent to Set-Top boxes (STBs) via Fixed Wireless Access (FWA) access. This predominantly includes streaming live and and on-demand 2D services to apps and browsers, including the ability to provide a certain amount of interactivity provided by apps and browsers.


However, broadcasters and content providers are experimenting with and trialing an increasing number of advanced media services. These include audio and video components and offer more advanced interactivity, quality, functionality and immersiveness.


Such services and experiences may include, but are not limited to:

  • Interactive video services

  • In-stadium multiview services

  • Virtual Reality Experiences:

  • 3D Scene-based media

  • Volumetric videos

  • Free viewpoint video


This above advanced media services only serve as examples for potential candidates. More details need to be documented in the course of the work item.

“Advanced Media Services” may result in special requirements in terms of capturing, contribution, production, encoding, distribution, decoding, rendering, security and user interfaces. Generally, it is expected that the services will be developed independently of the distribution network and will heavily rely on an IP/cloud/CDN-based delivery system. Additional aspects relevant for such “Advanced Media Services” include high volumes of data, complex decoding and rendering, and requirements to stay within interactive and the immersive limits, such as regarding motion-to-photon and motion-to-sound latencies.  Split-compute and split-rendering distribution architectures are expected to be relevant to make such services feasible and scalable on existing and emerging end devices including TVs, phones, tablets, HMDs, AR glasses and other type of advanced end points.

This WI covers the following objectives:

  • Collection of “Advanced Media Services” use cases including reference to existing trials, prototypes and experimental services.

  • Mapping of these use cases to one or several contribution architectures (if appropriate) and distribution architectures, addressing different service scenarios

  • Definition of Quality-of-Experience metrics associated to each of the “Advanced Media Services”

  • Collection of relevant network and service requirements on the “Advanced Media Services”

  • Mapping of existing 5G specifications against these requirements and identification of potential gaps, possibly supported by early prototyping

  • Potential input to 3GPP standardization processes


WI: 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.


WI: 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.


WI: 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.


WI: 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.


WI: 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.


WI: LTE-based 5G Terrestrial Broadcast

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.


WI: Feasibility Analysis for Audiovisual Production over 5G

5G-MAG members have identified a series of technical features in the 5G specifications applicable to audiovisual production scenarios (see "Towards a comprehensive 5G-based toolbox for live media production"). 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
