What is LTE-based 5G Terrestrial Broadcast? LTE-based 5G Terrestrial Broadcast is a broadcast system designed and standardized by 3GPP, the organization responsible for developing global mobile communication standards (e.g. 3G, 4G, 5G). As this broadcast system is part of the 3GPP family of standards, it may be fully integrated into 3GPP equipment and complemented by conventional mobile broadband data. LTE-based 5G Terrestrial Broadcast includes features to support: Receive-only mode / free-to-air reception, requiring no uplink or SIM card; Encrypted services, including authentication mechanisms; Dedicated broadcast networks and related infrastructure; Single frequency networks (SFNs); Fixed, portable and mobile reception; Quality of service (QoS) defined by service providers; Standard APIs for easy design and integration of media services in applications and devices. The standardization of LTE-based 5G Terrestrial Broadcast began in 3GPP Release 14, under the EnTV work item. EnTV was completed in the summer of 2017, substantially meeting the requirements set out for dedicated broadcast. 3GPP Release 16, completed in 2020, introduced new configuration parameters for enhanced support of high-power high-tower (HPHT) networks and greater mobility. All of the features introduced form the LTE-based 5G Terrestrial Broadcast standard. Applications for the media industry SERVICES SUPPORTED LTE-based 5G Terrestrial Broadcast could be used to: Distribute public and commercial linear TV and radio services, free-to-air or encrypted, to 3GPP compatible devices such as smartphones, smart TVs, or car infotainment systems; Enable personalized media offers by delivering linear broadcast content alongside catch-up and on demand using the same family of standards; Enable broadcast distribution of linear TV and radio services integrated into existing media applications with 3GPP-defined APIs. LTE-based 5G Terrestrial Broadcast may be used in combination with broadband connectivity, in which case a SIM card or subscription would be required to access the latter. NETWORKS SUPPORTED The enhancements of 3GPP Releases 14 and 16 allow typical terrestrial broadcast system network topologies to be used. For example, exclusively high-power high-tower (HPHT), low-power low-tower (LPLT) or medium-power medium-tower (MPMT) sites may be used to form a broadcast network. A mixture of different transmitter classes may also be used. The latter is important as mixed networks are typical in the real world. 5G Broadcast can be operated as either a single or multi-frequency network. Flexible network deployments support targeting of different receiver environments, from fixed roof-top reception in rural or urban areas to mobile reception at low, medium or high speeds, depending on the network design. 5G-MAG and LTE-based 5G Terrestrial Broadcast 5G-MAG studies the use cases and implementation, commercial, and regulatory aspects required for the deployment of LTE-based 5G Terrestrial Broadcast as part of the technologies available in 3GPP addressing media industry requirements.

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. What is a stand-alone NPN? A stand-alone Non-Public Network (SNPN) is an isolated network whose radio access network (RAN) and core network functions and services do not rely on a public mobile network. SNPNs may be deployed as fixed or nomadic networks, managed either by the entity making use of the NPN or a third party. They have full control and management capabilities for the network functions and services provided by the SNPN. For media organizations, SNPNs can support specific media production and contribution requirements that may not be met by public mobile networks, which usually target general public usage. The SNPN, based on 3GPP-defined technologies, has its own dedicated NPN ID and can host specific vertical industry devices (e.g. PSME equipment). All network functions are deployed inside the SNPN and isolated from public networks. This setup does not exclude the possibility of accessing public services through a firewall or establishing roaming agreements with public network operators if required. Main characteristics Quality of service: Full customization of key parameters for media production (e.g. low latency, high-throughput, uplink-downlink ratios, high reliability, real-time monitoring, etc.) Isolation: Device subscription data, communication data flows, and operation and management data are internal to the SNPN IT security and integrity: Guaranteed security and privacy for media-related data, accessible only under authorization Operation and management: Self-operation and management is possible, with full autonomy 5G infrastructure: 5G network infrastructure is provided by the party acting as SNPN operator Cost: All costs, including infrastructure and terminals, are carried by the media organization Coverage: Provided and defined by the SNPN Liability: Responsibility lies with the media organization Spectrum: Possibility to use dedicated spectrum outside of traditional mobile spectrum bands Applications for the media industry ON-SITE PRODUCTION AND VENUES Live events usually take place in theatres, concert halls, stadiums or production studios, and can be outdoors or indoors. 5G wireless connectivity provided by an SNPN at the venue would allow wireless production equipment required to capture and produce an event to be connected on-site within a local network. Connectivity would be limited to the event area and under the full control of the media organization, with all audio and video processing done in real-time during operation. Different wireless video and audio sources and devices, such as cameras, microphones, in-ear monitoring (IEM) systems, lighting, etc., can be automatically and quickly provisioned through the network and locally addressable. Content can be captured at the highest quality possible while ensuring its integrity and robustness. With high quality and extremely reliable radio links, tolerance of QoS (quality of service) impairments is very low. Audio/video streams are ingested or received into and out of the SNPN with 5G links that replace legacy OFDM technologies. It is also possible to provision computing capabilities on-site for processing, and internet access to enable, for example, remote control. SPECIAL EVENTS COVERAGE This scenario is typical of self-contained small-scale production environments such as those used in news and sports reporting. An SNPN may be provisioned temporarily in a given location allowing user and control data to remain confined within the SNPN and operated and managed by the SNPN owner or a third party. This scenario envisages contribution links from 5G-enabled equipment and a self-provisioned 5G network (e.g. located at a small outdoor broadcast van) to the cloud and/or central studios. Internet access for remote control may also be provisioned. 5G-MAG and stand-alone NPNs 5G-MAG members are engaging in the standardization of NPNs in 3GPP, analysing the most relevant applications for media production, PMSE equipment requirements, and regulatory and spectrum aspects.

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. What are Non-Public Networks? Media production facilities are increasingly adopting IP-based infrastructure. The ubiquity of IP networks and technologies enables increasing efficiency and effectiveness in production, process automation, and greater flexibility. Content production and contribution could leverage 5G as a highly reliable wireless technology to enhance existing or enable new workflows in the areas of newsgathering, remote production and live event coverage as well as in dedicated production facilities. NPNs are a key enabler for the deployment of media production scenarios. They are currently under standardization in 3GPP, with the first functionalities specified in Release 16. NPNs offer the possibility of providing 5G network services to organizations without entirely relying on public mobile networks. The latter may not be able to support certain applications, for example those requiring very low latency, highly robust services or business-critical data privacy – meeting such requirements may not be the primary business focus of public mobile network operators. NPNs therefore enable the deployment of 5G to provide services that may not be available in public mobile networks and are tailored to the needs of a specific industry, in this case media organizations. To enable a full degree of interoperability, NPNs should be connected to existing media production network infrastructure. Applications for the media industry NPNs may satisfy the demanding performance requirements of content production, such as very low latency and precise synchronization, and with respect to security, privacy and liability, by means of isolation from public networks, using dedicated resources and associated security credentials. They may be deployed stand-alone or in conjunction with public networks. Different NPN deployment options may be suitable depending on the type and scope of the production events, preferred business models and regulatory options. NPNs can be deployed as temporary or permanent. Permanent networks may cover a geographically limited area, as small as a small a single building or venue, or an entire campus used by audiovisual media production organizations. For nomadic or temporary productions (e.g. touring events, festivals, etc.), the preferred option may be a stand-alone NPN that can support the production anywhere and at any time. It would function independent of public mobile network coverage and avoid the need for negotiation of contracts and service-level agreements with multiple, diverse mobile network operators across country borders. For productions with less demanding requirements (e.g. newsgathering, low-cost live), service-level agreements and commercial arrangements between different types of network operators will need to be compared in order to obtain the right balance between functionality and cost with respect to the potential use of NPNs. The choice of deployment options for an NPN will be based on considerations around spectrum availability, network ownership and operation, and security, privacy and liability. The deployment of NPNs for media production and contribution can: Provide traffic isolation from other networks to ensure stable performance, reliability, security, or privacy. Meet requirements traditionally out of scope of general-purpose public mobile networks. Provide robust security and privacy features through, for example, dedicated credentials for on-boarded equipment. Facilitate self-management and operation without the need to rely on third parties 5G-MAG and Non-Public Networks 5G-MAG is monitoring the standardization of NPNs and their relevant features in 3GPP to understand the road map, timelines and expected support for audiovisual media production applications in both network and user equipment. 5G-MAG analyses different national approaches and emerging licensing models for making spectrum available for NPNs. 5G-MAG believes that the existence, across Europe and possibly worldwide, of a common spectrum range with homogeneous frequency channelization for NPNs in media production would help create economies of scale for their commercial deployment and operation. Furthermore, technical harmonization of protocols and workflows for spectrum access for NPNs in media production would be beneficial for both vendors and users. 5G-MAG believes that access to spectrum for nomadic NPNs and short-term deployments also needs appropriate regulatory frameworks, as the current national regulatory approaches are primarily suitable for stationary and long-term NPN deployments. Beyond spectrum access, 5G-MAG also studies regulatory aspects that may be relevant for the deployment of NPNs, such as numbering and network identifiers, roaming between public networks and NPNs, networksharing approaches and site regulations.

Download (PDF) ABOUT THE REPORT This is a report produced by the 5G-MAG Workgroup CP (Content Production - Standards and Architecture). Current version of the report: v.1.0 Date of publication: 7th September 2023 ABSTRACT 5G-MAG has studied deployment scenarios for live media production using Non-Public Networks (NPNs), both stand-alone and in public networks. The 5G-MAG report " Towards a comprehensive 5G-based toolbox for live media production " presents high-level scenarios involving 5G devices for media applications. Before using them, devices need to first gain access to the 5G network though several registration and authentication procedures. After use, devices should be "de-registered", i.e. have their access rights revoked. This report provides: Information on the registration, authentication and onboarding procedures for devices in NPNs guidelines for users and operators of 5G NPNs in relation to aspects such as network identifiers and storage and local and remote provisioning of credentials REQUEST FOR FEEDBACK 5G-MAG welcomes feedback from the community to this document.

We are happy to announce the release of version 1.2.1 of the 5GMS Application Server. This is a bug-fix release to address two issues found during deployment. The first issue was that ingest requests to upstream media origin servers did not use SNI for TLS connections. This caused ingest fetches to media origins, that require SNI in order to function correctly (name based virtual hosting), to fail which resulted in the media not playing back. This is now corrected and the OpenResty web proxy is instructed to use SNI in its TLS connections. The second issue affected some versions of OpenResty when dynamic redirection learning was used. In these cases the cache key for the original redirected request and the cache key for the redirected URL were calculated as the same value causing a recursive loop and then failure to fetch from the redirected upstream media source. This manifested as a 500 error upon request of the redirected URL. A simple change to distinguish these two cache keys fixed this issue. 👉 The release can be found at: https://github.com/5G-MAG/rt-5gms-application-server/releases/tag/rt-5gms-application-server-1.2.1 The full change log can be found on the release page. 👏 Big thank you to the contributor David Waring ( BBC ). 👉 More information about 5G-MAG and the 5G-MAG Reference Tools can be found on our website: developer.5g-mag.com/

Download (PDF) ABOUT THE REPORT This is a report produced by the 5G-MAG Workgroup CD (Content Distribution - Standards and Architecture). Current version of the report: v.1.0 Date of publication: 1st December 2023 ABSTRACT Time and Frequency Interleaving (TFI) is a key feature for robust broadcast transmissions in time-frequency varying environments, in particular for mobile reception. TFI was considered and evaluated by multiple companies during the 3GPP Rel-16 standardisation of LTE-based 5G Broadcast with significant support from companies. Furthermore, time interleaving has also been proposed for NR MBS Broadcast Services in 3GPP Rel-17 . Multiple papers have been published on the performance of TFI for LTE-based 5G Broadcast (BBC, Qualcomm). In summary, a significant number of papers and work from different sources is available showing the performance benefits of TFI and hence, the consensus view within 5G-MAG is that addressing the topic in 3GPP specifications would be valuable to increase the robustness of the broadcast services specified by 3GPP. To support the specification development in 3GPP, 5G-MAG has produced this 5G-MAG Report summarising key results and potential specification impact to introduce Time-Frequency Interleaving for broadcast services in 5G systems.

Current version of the report: v.1.0 Date of publication: 28th October 2024 ABSTRACT The implementation and deployment of mobile technologies as part of media production workflows paves the way for a new ecosystem of equipment, devices and roles in the industry. With this new ecosystem, new roles emerge, which need new definitions and clarification in their responsibilities. Some of these roles have been around for a long time but, over the years, their meaning or ownership have changed. Other roles are completely new in the context of media production and therefore require a precise introduction to foster understanding and support for them. This report: introduces traditional roles for media production and contribution based on RF/OFDM links, explains the vertical ecosystem within 5G, introduces new roles for content production and contribution networks based on NPNs, and defines responsibilities of and dependencies between these new roles.
