From architecture to reality: What CBC's Milano Cortina 2026 workflows tell us about DMF and MXL in live sport By Paul Markham

Architectural frameworks only prove their value when exposed to real-world pressure. For the European Broadcasting Union's Dynamic Media Facility (DMF), that pressure is expected to arrive early this year, as broadcasters begin applying elements of the architecture in live environments rather than laboratories.
One of the earliest publicly referenced scenarios involves CBC/Radio-Canada, with selected Milano Cortina Olympic workflows identified on the DMF/MXL roadmap for February 2026.
In Parts One and Two of this series, we outlined why DMF exists, how the Media eXchange Layer (MXL) underpins it architecturally, and whether the ecosystem is genuinely moving beyond theory. We examined broadcaster engagement, early vendor alignment, and the reality of hybrid, pre-commercial implementations. This final article moves from architecture and adoption to application, exploring what those ideas look like when tested under the operational pressure of a live Olympic event.
Why Milano Cortina 2026 matters
Large-scale sport remains the most demanding environment for broadcast technology to evolve. Olympic workflows combine extreme scale, hard real-time constraints, multi-format output, and a non-negotiable requirement for reliability. If a new architectural approach can work here, even partially, it can work anywhere.
Milano Cortina will not mark the end of the DMF journey, but it may mark the point at which DMF principles begin to shape mainstream live production, with MXL following as platforms and products catch up
Events of this scale also provide some of the clearest opportunities to benefit from dynamic compute and cloud capacity. Reducing reliance on fixed, peak-provisioned infrastructure, whether on site or remote from the event, offers tangible gains in cost efficiency, operational flexibility and sustainability.
As a technically progressive public broadcaster, CBC/Radio-Canada has been closely involved in DMF and MXL discussions from an architectural standpoint. Milano Cortina represents an opportunity not to deploy DMF wholesale, but to apply DMF thinking selectively, in ways that are realistic for a Tier-1 live event.
What DMF does and does not mean for an Olympics
DMF is a reference architecture, not a turnkey system. It describes how a broadcast facility can be decomposed into modular, software-defined media functions running on general-purpose compute, orchestrated dynamically across on-prem, edge and cloud environments.
At Milano Cortina, this does not mean replacing OB trucks, ST 2110 routing, or established Olympic production practices. Instead, DMF adoption is focused on introducing software-defined processing where it delivers clear operational benefit, while allowing existing infrastructure to continue doing what it already does well.
In practice, DMF-based workflows tend to emerge first inside internal processing domains rather than across end-to-end signal transport. These are the parts of the production chain where modularity, elasticity and rapid software iteration offer the greatest immediate return.
At events such as Milano Cortina, that typically means clusters of software-defined media functions handling tasks such as live clipping and highlights creation, multi-angle and iso-camera processing, graphics insertion and data-driven overlays. These workflows benefit from being loosely coupled, scalable, and easier to redeploy across productions.
Hybrid deployment is central to this model. Some processing remains close to venues, while other functions can be centralised or cloud-adjacent. DMF explicitly supports this topology, allowing media functions to be deployed where latency, resilience and operational efficiency make the most sense, rather than forcing everything into a single location or platform.
MXL's role: future direction, not event deliverable
As established earlier in the series, MXL is the media-plane component of the DMF architecture: an open, high-performance mechanism intended to enable interoperable media exchange between software-defined production functions.
For Milano Cortina, however, MXL should be understood as a direction of travel rather than a deployed component. Product availability, maturity and integration timelines mean that CBC's Olympic workflows are applying DMF principles today, while planning to evolve towards MXL-based exchange as platforms and vendor support mature.
This distinction reinforces that DMF adoption does not require every architectural component to be present from day one, and that meaningful progress can be made by aligning platforms and workflows ahead of full standard implementation.
Operational reality: hybrid by design
Milano Cortina reinforces a reality many broadcasters already recognise: hybrid operation is not a temporary transition, but the steady-state condition of modern live production.
DMF-based workflows at the Games are expected to combine software-defined processing with conventional IP devices and gateways, alongside vendor platforms at different stages of architectural alignment, running across both on-prem and cloud-native compute. That mix introduces new operational considerations around monitoring, observability and fault isolation.
Software-defined workflows may introduce new failure modes, but they also enable faster iteration, recovery and reuse. Milano Cortina will test how well those trade-offs are understood and managed under genuine live-event pressure.
Vendor collaboration under pressure
For vendors, CBC's Olympic deployment is not a marketing exercise. It is a test of engineering collaboration under real deadlines, interoperability between evolving platforms, and perfor
