We are happy to announce that the 5G-MAG Steering Group has approved phine.tech as new member of 5G-MAG. About phine.tech At phine.tech, we believe the real value of 5G isn't just faster mobile internet - it is the key to unlocking precision, automation, and intelligence at an industrial scale. However, we also know that for many developers and industrial innovators, the world of telecommunications remains expensive, slow, and overly complex. We exist to close the gap between 5G vendors and the industries that need them most. By combining deep expertise in telecommunications with the agility of modern software engineering, we are simplifying 5G to make it accessible for everyone. It is a philosophy we are already carrying forward as we lay the foundation for 6G. Headquartered in Vienna, Austria, we are building the tools that empower the next generation of industrial use cases. Our flagship solution, the Virtual 5G Lab (V5GL), replaces weeks of hardware setup with a cloud-based, developer-friendly environment that is ready in seconds. Whether for robotics, manufacturing, or research, we provide the infrastructure so you can focus on the innovation.

Throughout the session, he manages logistics, transitions between speakers, and encourages questions, aiming to create a collaborative environment for discussing energy‑efficient media delivery. Julien Lemotheux (Orange / 3GPP SA4 Rapporteur) Julien Lemotheux (Orange) provided the operator perspective, explaining Orange’s commitment to achieving net‑zero carbon by 2040 and the challenges that come with it. He notes that while fixed networks have become more efficient—“it was a good thing to switch from ADSL to fiber”—mobile network energy consumption continues to rise despite optimization efforts. He referred to the work in 3GPP and highlighted some of the opportunities to leverage 3GPP media streaming architectures to gather energy data and drive optimizations in coordination between media applications and the 5G/6G systems. A central issue, he argues, is the lack of granular, shareable energy data across devices, networks, and services. Benjamin Schwarz (Greening of Streaming) Benjamin describes Greening of Streaming’s mission as an evidence‑driven effort to reduce energy consumption in video delivery, stressing that “we only work on things that we can actually measure in watts.” He outlines the organization’s lab structure and its flagship REM (Remote Energy Measurement) project, which measures energy use from encoders through to end‑user devices. He shares several findings: home gateways typically consume around 10 watts continuously regardless of traffic; peer‑to‑peer delivery adds only 0.1–0.2 watts per peer; and enabling eco‑mode on TVs can reduce consumption by roughly 20%. He also highlights that content characteristics—especially brightness—have a far greater impact on device energy use than codec or resolution choices, and that some OLED TVs surprisingly consume less power when playing 4K content than HD. Marisol Palmero (Greening of Streaming) Marisol focuses on the standards landscape, arguing that today’s energy‑related metrics are fragmented across encoding, CDN, network, and device domains. She notes that “there is no standard that will give you the measurement… in an end‑to‑end use case,” which limits coordinated energy optimization. She describes ongoing work in the IETF GREEN working group, where a YANG‑based data model is being developed to represent device‑level energy metrics in real time. The model is about 70% complete at the device‑component level, with upcoming work focused on controller interactions and API definitions. She also previews a video‑streaming‑focused hackathon planned for the next IETF meeting in Vienna, intended to advance cross‑SDO collaboration between IETF, 3GPP, and Greening of Streaming. Lucas Gregory (ATEME) Lucas presents the SmartCD project, a French collaborative effort led by ATEME to measure and reduce the environmental impact of end‑to‑end streaming workflows. He explains that cloud‑based measurement is particularly challenging because providers rarely expose real energy data, noting that “measuring the environmental impact of streaming workflows in the cloud is really challenging.” To address this, the project relies on resource‑usage metrics—CPU, memory, network traffic, storage activity—combined with energy models. Lucas emphasizes that understanding where energy is consumed is a prerequisite to meaningful optimization and that device generation plays a major role in decoding and rendering energy. Christian Timmerer (University of Klagenfurt) Christian shares academic research on energy‑aware encoding, bitrate ladder design, and adaptive bitrate (ABR) algorithms. His work shows that slower encoder presets significantly increase energy consumption with diminishing returns in quality, and that “small quality reductions can still yield substantial energy savings.” He presents energy‑aware bitrate ladders and an energy‑optimized ABR algorithm (eVISH), along with metrics for video complexity, decoding energy, and CO₂ prediction. While industry interest exists, he notes that commercial adoption is limited because customers rarely prioritize or pay for energy‑saving features. Martin Lasak (Fraunhofer FOKUS) Martin describes Fraunhofer’s measurement framework, which combines power meters with detailed streaming analytics to understand energy use across devices and workflows. One of the most striking findings is that TV eco‑mode has a dominant impact on energy consumption, yet “many devices were not using echo mode” in real‑world tests. He also confirms that content brightness and device settings outweigh technical parameters like bitrate or resolution in determining energy use. Fraunhofer is exploring LLM‑based user guidance to help viewers reduce energy consumption and is also measuring encoder energy across software and hardware implementations. Daniel Silhavy (Fraunhofer FOKUS / 5G‑MAG Reference Tools) Daniel presents the 5G‑MAG reference tools, which implement 3GPP specifications and provide an open‑source environment for experimenting with media delivery, QoE metrics, and client‑side data collection. He explains that “the reference tools can really be a starting point if you want to try something out,” positioning them as a potential foundation for prototyping the Energy Information Application Function proposed earlier in the workshop. The tools already support CMCD, QoE reporting, and UE data collection, making them well‑suited for future energy‑related experimentation.

We are very excited to welcome Dr. Renata Teixeira, Staff Research Scientist at Netflix, to talk about their analysis of Netflix Streaming over Low Earth Orbit (LEO) satellite networks. The talk will also focus Quality of Experience (QoE) metrics, a relevant topic being explored in 5G-MAG. Abstract : Low Earth Orbit (LEO) Satellite Networks bring broadband to new places—and new challenges to streaming. Netflix measurements from millions of households in 147 countries show that LEO now represents a meaningful share of global streaming traffic. Overall quality can match terrestrial access, yet rapid throughput swings and packet‑loss bursts increase bitrate switches and stall risk. We characterize these effects and LEO’s growing role in video delivery, map the tradeoffs for transport and adaptive bitrate algorithms, and outline priorities for future work on Low Earth Orbit streaming. This talk builds on our SIGMETRICS 2025 study, “A Global Perspective on the Past, Present, and Future of Video Streaming over Starlink”( https://dl.acm.org/doi/10.1145/3726854.3727268  ( https://dl.acm.org/doi/10.1145/3726854.3727268 ) ), in collaboration with Liz Izhikevich (UCLA), Reese Enghardt (Netflix), and Te‑Yuan Huang (Netflix).   Bio : Renata Teixeira is a Staff Research Scientist on the Streaming Algorithms team at Netflix. She earned a Ph.D. in Computer Science from UC San Diego in 2005, conducting research on Internet routing at AT&T Research.
