What the 5G-EMERGE Third White Paper Means for Media Delivery

‍By Bea Alonso, Advisor & Marketing Lead, Humans Not Robots

The third white paper from the 5G-EMERGE project—Satellite-Enhanced Media Delivery at the Edge: Architecture & Innovation—marks a significant milestone in the development of next-generation content distribution. Published in March 2026, it sets out a technical blueprint for converging satellite, 5G, and terrestrial IP networks into a single, standards-based media delivery ecosystem.

Humans Not Robots is a proud member of the 5G-EMERGE consortium, a 33-partner collaboration led by the European Broadcasting Union (EBU) and funded by the European Space Agency (ESA) under its ARTES programme.  

In this blog, we summarise the paper's key findings and what they mean for broadcasters, satellite operators, and telecoms providers navigating the future of media distribution.

What Is 5G-EMERGE and Why Does It Matter?

No single network infrastructure can meet all the demands of modern media distribution. Bandwidth limitations, coverage gaps, latency, and rising operational costs continue to challenge the industry. 5G-EMERGE addresses this by intelligently combining satellite and terrestrial networks to deliver high-quality media content, live or on-demand, to virtually any device, anywhere.

The project operates across four use-case categories:

• Direct-to-Home (DTH) – Satellite delivery to residential premises ‍
• Direct-to-Vehicle (DTV) – In-vehicle media services on the move ‍
• Direct-to-Edge (DTE) – Content pushed to network edge nodes for local distribution ‍
• Direct-to-Device (DTD) – New in Phase 2, delivering content directly to smartphones via 5G non-terrestrial networks

The Architectural Blueprint: Modular, Open, and Future-Proof

At its core, the 5G-EMERGE architecture is designed around a set of clear principles: modularity, openness, scalability, resilience, and sustainability. Rather than replacing existing infrastructure, it functions as a satellite-enhanced content delivery network (CDN) within a multi-CDN environment—complementing and extending what broadcasters and telcos already have in place.

The architecture is built on widely adopted open standards, including DVB-S2X, 3GPP 5G Media Streaming, and MPEG-DASH, ensuring device-agnostic delivery to any IP-enabled endpoint. A unified IP streaming stack runs across all delivery paths, making the system transparent to end users regardless of how their content arrives.

As part of the initiative, HNR is responsible for QoS, QoE, QoI, and Content Steering, as well as enabling media streaming within the project. Our analytics platform, HNR to ZERO, has been deployed to rigorously assess the project's total energy footprint. Our solution not only reports but also drives actionable system adjustments that enhance operational efficiency and enable a sustainable approach to High-Quality Content Delivery for 5G-EMERGE.

Key Technical Innovations in Phase 2

5G-EMERGE's latest white paper details five areas of technical innovation that have moved the project from concept to near-market readiness:

• Media Streaming Platform – Adapted to support live and on-demand delivery, with integration across major open-source media players and CDN providers ‍
• Edge Security – AI-enhanced Web Application and API Protection (WAAP) and DDoS mitigation, securing distributed edge infrastructure at multiple network layers ‍
• Edge Orchestration – Containerised media applications deployed and managed remotely across heterogeneous infrastructure, aligned with ETSI MEC and 3GPP standards ‍
• Intelligent Caching – A combination of reactive, proactive, and segmentation-based caching strategies that reduce distribution costs and improve user experience ‍
• 5G Components at the Edge – Satellite-enabled 5G Non-Public Networks with dynamic gateway selection, multicast support, and CAMARA API integration for network exposure

Key Takeaways from the White Paper

Several outcomes stand out from the work presented:

• Near-universal coverage is achievable by combining satellite and terrestrial networks, including in remote regions and during terrestrial outages ‍
• Sustainability improves when bulk and repetitive traffic is offloaded via satellite multicast, reducing both unicast bandwidth consumption and carbon footprint ‍
• Market-ready prototypes now exist for all four use cases—including low-cost steerable antennas, mABR gateways, and NR-NTN chips—demonstrating a credible path from lab to commercial deployment ‍
• Security is built in, not bolted on, with AI-driven threat detection and hardened operating environments at the edge ‍
• Openness is non-negotiable—the architecture avoids vendor lock-in by adhering to established international standards throughout

Satellite-Terrestrial Convergence: The Road Ahead

The 5G-EMERGE project concludes Phase 2 in Q4, 2026. What the third white paper makes clear is that the convergence of satellite and terrestrial networks is no longer a theoretical proposition. It is a commercially viable, technically validated approach to solving media distribution at scale.

For broadcasters looking to extend reach, satellite operators seeking new revenue models, and telcos managing growing demand for video traffic, the architecture described in this paper offers a practical framework worth examining closely.

Discuss the Findings with HNR

As an active member of the 5G-EMERGE consortium, we have direct insight into the project's architecture, innovations, and market implications. A core tenet of the project is that the resulting technology is commercialised, so if you want to explore how satellite-enhanced edge delivery could apply to your organisation, or discuss any of the technical challenges addressed in the white paper, we would be happy to hear from you.
