How MPEG-5 LCEVC Is Rewriting the Economics of Video Quality
V-Nova | MPEG-5 LCEVC
The Evidence Base
Claims about codec performance are easy to make and difficult to verify. What distinguishes LCEVC is the breadth of independent validation behind it.
The foundational assessment came from MPEG itself. In 2021, formal verification tests at the 134th MPEG meeting used ITU-R BT.500 DSIS methodology, the gold standard for subjective quality assessment, with trained viewers in controlled laboratory conditions. The results: 46% bitrate savings when enhancing H.264/AVC and 31% when enhancing HEVC, both for UHD content. Nine independent studies have since reinforced those findings across different codecs, content types, and methodologies:

Three findings stand out. First, the consistency of results across independent labs, base codecs, and content types from broadcast television to live gaming suggests the efficiency gains are structural, not circumstantial. Second, LCEVC adds easily manageable processing overhead while enabling encoding speeds 3.1–3.6x faster than full-resolution alternatives. Third, the gains hold under real-world conditions including packet loss and low-latency constraints.

The Brazil Proof Point
Brazil’s TV 3.0 initiative branded DTV+ for consumers provides the most consequential deployment validation. On August 27, 2025, President Lula signed the decree formalizing TV 3.0 into law. The standard mandates VVC compression, MPEG-H audio, and MPEG-5 LCEVC enhancement. It is the first national broadcast standard to require LCEVC.
The rationale was pragmatic. Brazil must deliver UHD to over 200 million viewers using limited terrestrial spectrum. Current HD services consume approximately 14 Mbps per channel on private television spectrum. By combining VVC with LCEVC, TV 3.0 achieves 4K HDR at under 10 Mbps per channel. Independent verification by the University of Brasilia confirmed that LCEVC-enhanced VVC matched subjective quality at 8.08 Mbps where standalone VVC required 12.54 Mbps.
During the Paris 2024 Olympics, Globo ran the full TV 3.0 stack in live production: UHD feeds encoded at 10 Mbps, decoded on consumer devices, including TVs from Hisense and set-top boxes with silicon from Realtek and Amlogic. Pilot DTV+ transmissions launched in Rio de Janeiro in 2025, with commercial services targeting the 2026 World Cup.
THE BIGGER PICTURE
Brazil solved the chicken-and-egg problem that historically blocks video technology adoption by tying deployment to a concrete commercial milestone, forcing silicon vendors, encoder manufacturers, and device makers to deliver simultaneously. LCEVC’s inclusion validates not just efficiency but ecosystem maturity.
Four Deployment Vectors
While broadcast provides the highest-profile proof point, LCEVC’s codec-agnostic design makes it relevant across the full delivery spectrum.

For streaming and OTT platforms, LCEVC offers up to 40% compression efficiency improvement and a 70% reduction in transcoding costs and energy consumption. Research published in SPIE Proceedings demonstrated that LCEVC-enhanced SVT-AV1 achieves 75–85% encoding time savings through fast parameter selection, while maintaining equivalent quality as measured by VMAF_NEG. On the decoding side, LCEVC reduces CPU utilization by 19–51% depending on preset and quality level. These are not marginal operational savings. For platforms processing millions of hours of content, the economic impact of reducing per-title encoding costs while simultaneously improving delivered quality represents a structural advantage. The technology integrates with standard encoding pipelines through commercially available MainConcept SDK, Harmonic XOS and Ateme TITAN, and decodes through widely adopted players including Shaka Player and GStreamer 1.26+.
For pay TV operators, the value proposition is preservation rather than replacement. Operators can deliver 1080p HDR at the bitrates currently used for SD content on their installed set-top boxes. Devices built on Realtek, Amlogic, and Montage LZ silicon support LCEVC playback through a compact software module that utilizes the existing SoC. Legacy devices continue to decode the base stream normally, while modern units gain enhanced quality through a firmware update. No truck rolls. No hardware swaps. No subscriber disruption.
For cloud gaming and XR applications, latency and bandwidth constraints are far more severe than in traditional streaming. V-Nova and NVIDIA demonstrated at NAB 2024 that LCEVC enhancement applied to NVENC HEVC reduced bandwidth requirements for a popular XR application by 55%, from 55 Mbps to 25 Mbps. In low-latency cloud gaming scenarios, LCEVC achieved 30% compression gains while operating within the tight encode-decode cycles that interactive applications demand. The technology also powers six-degree-of-freedom (6DoF) VR streaming, including that of V-Nova’s PresenZ media format, enabling photorealistic volumetric content delivery to lightweight client devices.
Brazil’s TV 3.0 is built on ATSC 3.0 physical layer technologies, and that architectural alignment has direct implications for the United States. As of late 2024, 76% of the US population was within reach of an ATSC 3.0 NextGen TV signal, with broadcasts available in nearly 70 markets. LCEVC is already included in the ATSC A/345 standard specification, providing a future-proofed path for US broadcasters to upgrade their services. Ateme’s TITAN Live encoder, already deployed in over 40 US markets for ATSC 3.0 NextGen TV transmission, has already demonstrated support for LCEVC at the 2025 ATSC NextGen TV conference. By integrating LCEVC, broadcasters can reduce the bitrate required for 4K HDR content by up to 40% while simultaneously lowering encoding complexity and cost. The technology’s validation in Brazil’s live Olympic broadcast provides operational confidence that US deployments can reference.
The Economic Argument for Enhancement Over Replacement
The traditional codec upgrade cycle follows a predictable pattern: a new standard is ratified; hardware support lags by several years, encoding infrastructure must be rebuilt, and the industry gradually migrates over a five-to-seven-year period. During that transition, platforms must maintain parallel encoding pipelines, support multiple codec profiles, and manage the complexity of serving a fragmented device landscape.
LCEVC disrupts this cycle because it works with the codecs that platforms are already using. An operator currently deploying H.264 can gain 46% bitrate savings by adding LCEVC, without waiting for their entire device fleet to support HEVC or VVC. A platform that has already invested in HEVC infrastructure can extend its efficiency frontier by 31% without rebuilding its encoding pipeline. And when VVC eventually achieves broad device support, LCEVC can enhance it further, delivering 36–55% additional savings depending on content and configuration.
This is not a theoretical distinction. It changes how platforms plan their technology roadmaps. Instead of large, discontinuous infrastructure investments timed to codec transitions, operators can pursue continuous, incremental efficiency improvements that compound over time. The encoding infrastructure investment is preserved rather than stranded. The device compatibility challenge is reduced rather than replicated.
THE BIGGER PICTURE
The environmental implications deserve attention. LCEVC’s ability to reduce transcoding compute requirements by 40 to 70% at equivalent quality translates directly into lower energy consumption for encoding operations. For large-scale streaming platforms processing millions of hours annually, the aggregate power reduction is substantial. As the industry faces growing pressure to reduce its carbon footprint, codec efficiency becomes an environmental question as well as an economic one
The Strategic Calculus
The video industry does not lack codec technologies. Missing however is the clear path from standardization to deployment that accounts for the realities of installed infrastructure, fragmented device ecosystems, and competing commercial priorities. LCEVC’s value is not that it outperforms any single codec in isolation. It is that it makes every codec it touches perform better, on devices that already exist, through infrastructure that is already in place.
Brazil’s TV 3.0 deployment is the proof that this approach works at national scale. The Paris 2024 Olympics broadcast demonstrated it in live production. The 50-company ecosystem at NAB 2025 demonstrated it across the full delivery chain. And the independent research, from MPEG’s own verification tests to peer-reviewed academic studies, confirms that the efficiency gains are real, reproducible, and consistent across content types, codecs, and viewing conditions.
For streaming platforms, broadcasters, and pay TV operators evaluating their next infrastructure investment, the question is not whether LCEVC works. The evidence on that point is settled. The question is whether it makes strategic sense to continue pursuing quality improvements through codec replacement alone, when a standards-based enhancement technology can deliver measurable gains on the infrastructure you have already built.
Video infrastructure is increasingly shaped by specialized hardware. VPUs dramatically improve the efficiency of video processing, but their real impact depends on how they are integrated into systems. Server architecture, device density, and thermal stability ultimately determine whether efficient silicon becomes deployable infrastructure.
Within the VPU ecosystem, Advantech represents the system design layer: the point where accelerator efficiency becomes operational reality. Rather than treating accelerators as optional add-ons to general-purpose servers, Advantech designs platforms where accelerators are central to the system’s purpose. Optimized PCIe topology ensures predictable bandwidth. Robust power architecture supports sustained multi-device operation. Intelligent thermal management maintains performance over continuous, long-duration workloads.
For platform architects and infrastructure engineers evaluating their next generation of video processing systems, the question is not simply which accelerator to choose. It is whether the system that surrounds it can deliver on the accelerator’s promise, consistently, at scale, in the environments where it actually needs to operate. That question is answered not by the silicon, but by the architecture beneath it.
