Nokia reports on recent MPEG verification tests for dual-layer VVC (H.266), which indicate that scalable video coding can achieve subjective quality comparable to single-layer VVC. The findings suggest potential for streaming providers to reduce CDN and storage costs by delivering multiple resolutions from a single bitstream.
The validation of dual-layer VVC quality suggests a shift toward more efficient adaptive bitrate streaming architectures. By utilizing a single bitstream for multiple resolutions, operators can significantly reduce storage requirements at the origin and edge, potentially lowering CDN costs while minimizing cache misses that cause video freezes. This development addresses the historical overhead barriers that prevented scalable video coding from gaining traction outside of video conferencing. As the industry seeks to offset the high costs of UHD delivery, the next signal to track will be the integration of these dual-layer configurations into commercial encoder hardware and player software ecosystems.
VVC adoption is accelerating across multiple fronts, with Nokia's dual-layer results arriving as the broader H.266 ecosystem matures. Ericsson and Nokia are diverging sharply on AI-RAN architecture, with Nokia committing its entire Layer 1 RAN to Nvidia's CUDA platform and GPUs, a strategic bet that positions Nokia's compute infrastructure for both network processing and media workloads. The company's investment in GPU-accelerated processing aligns with the computational demands of VVC encoding and decoding at scale, where hardware acceleration remains a prerequisite for real-time streaming applications. Nokia's broader push into agentic AI for network operations, including its Mobile Core Early Access program that lets operators trial AI-based features before full deployment, demonstrates the vendor's pattern of offering early-access pathways for emerging technologies, a model that could extend to VVC-based streaming services.
The commercial and licensing landscape for VVC continues to shape adoption economics for streaming providers. Nokia has combined with AWS and Databricks to build a unified telco data platform under its Autonomous Network Fabric architecture, claiming automation rates above 90 percent and service delivery times under four hours for operators using the platform. This infrastructure layer could serve as the delivery backbone for VVC-encoded content, particularly as operators seek to reduce per-bit costs for UHD streaming. The broader industry context shows Nokia pushing AI-RAN to improve spectral efficiency while creating an evolutionary path from 5G and 5G-Advanced toward AI-native 6G, suggesting that network-side efficiency gains may compound the compression savings that dual-layer VVC promises at the application layer.
Technical validation of VVC's streaming potential extends beyond Nokia's MPEG verification tests. A cluster of announcements in June 2026 signaled a shift from AI research to commercial AI-driven network automation across the telecom sector, with Ericsson launching its AI in RAN commercial software subscription claiming up to 20 percent higher downlink throughput across more than 15 live deployments. These throughput gains at the radio layer directly benefit VVC streaming by providing more consistent bandwidth for higher-bitrate UHD content delivery. The convergence of improved network capacity and more efficient codec architectures like multilayer VVC workflow creates a compounding effect: each percentage gain in spectral efficiency or compression ratio multiplies the other's impact on end-user quality of experience and infrastructure cost per stream.

MPEG verification tests have confirmed that dual-layer VVC achieves subjective quality parity with single-layer H.266. This development is significant because it allows operators to deliver multiple resolutions from a single bitstream without compression penalties, potentially reducing storage requirements, lowering CDN costs, and minimizing video freezes for end-users.
The tests confirmed that there is no statistically significant difference in Mean Opinion Scores between dual-layer and single-layer VVC, indicating that dual-layer streaming achieves subjective quality parity.
It allows providers to eliminate the need for separate HD and UHD storage by maintaining two bitrate versions within a single bitstream, which can reduce storage requirements and CDN costs.
Scalable VVC integrates scalability directly into the base codec design, requiring only high-level software syntax support rather than the complex extensions that hindered previous codec generations.
The industry is now looking toward the integration of these dual-layer configurations into commercial encoder hardware and player software ecosystems.
