SMPTE and EBU advance open standards for dynamic IP production
The IAMT provides an update on recent standards developments from organizations including SMPTE, AES, and the EBU. Key projects highlighted include the SMPTE Catena control system, EBU's Dynamic Media Facility (DMF) for IP-based production, and ongoing research into content authenticity protocols.
Key Takeaways
- SMPTE released six ST 2138 Catena documents as Public Committee Drafts, providing a single secure protocol for controlling multi-vendor media services.
- EBU and AMWA launched the Dynamic Media Facility (DMF) with an open-source Media Exchange Layer (MXL) to allow applications to share direct storage access.
- The AES70-4 standard for JSON-based audio control was approved, facilitating better integration of pro audio into software-defined networks.
- SMPTE is restructuring the DMSII metadata scheme into five parts to integrate Content Provenance and Authenticity (CPA) data directly into MXF files.
- A SMPTE Study Group on AI has initiated standards projects for AI model metadata registry and LLM-generated versioning.
Why It Matters
The shift from hardware-centric to software-defined production has created a control vacuum previously filled by proprietary vendor silos. Standardizing the 'control plane' via Catena and the 'exchange layer' via MXL provides a vendor-neutral framework for the industry’s migration to the cloud. By decoupling media functions from underlying hardware, broadcasters can dynamically reconfigure resources for live events, reducing idle-capacity costs. Watch for the results of the SMPTE CPA Study Group report, which will set the baseline for how the industry combats deepfakes by embedding provenance metadata natively into professional production workflows.
Additional Context
The push for media interoperability has accelerated as major broadcasters transition to flexible, software-centric operations. In April 2026, the European Broadcasting Union (EBU) updated its DMF reference architecture to refine how orchestration functions across distributed facilities, specifically clarifying the boundaries between compute resources and workflow management, per TVBEurope. This update aligns with a collaborative effort involving the Linux Foundation, which in 2025 took over hosting the Media eXchange Layer (MXL) project to foster a truly open-source ecosystem for real-time media transport. Key industry players including Grass Valley and Lawo have already begun demonstrating early interoperability pilots within this framework, per SVG Europe in January 2026. Simultaneously, the integration of artificial intelligence into media workflows has necessitated new technical guidelines to manage risk and security. In December 2025, SMPTE released Engineering Report ER 1011:2025, a comprehensive update produced in tandem with the EBU and the Entertainment Technology Center. According to NewscastStudio, the 54-page report addresses specific concerns regarding agentic AI, data poisoning, and the ethical implications of using large language models in content production. This technical groundwork is critical as the industry faces increasing regulatory pressure to disclose AI-generated content, a challenge the SMPTE Content Provenance and Authenticity Study Group is tackling by harmonizing metadata standards with the C2PA specification used by consumer platforms.
