SMPTE striving for a single protocol to control media devices & services
The Society of Motion Picture & Television Engineers (SMPTE) has introduced the initial documents defining the Catena control plane standard, which aims to unify device management across on-prem, cloud, and hybrid media workflows.
The product of extensive work by SMPTE’s Rapid Industry Solutions Open Services Alliance group (RIS-OSA), the initial Catena documents (known as the ST 2138 suite) were introduced to the SMPTE Standards Community, and its 34CS Technology Committee that focuses on Media Systems Control and Services, to begin the official standardisation process.
Chris Lennon, Director of Standards Strategy, Ross Video and a SMPTE Fellow, said, “With media workflows now spanning on-prem, cloud, and hybrid environments, the need for a unified, secure, and vendor-agnostic control plane is more urgent than ever.
“By introducing the initial Catena documents into the SMPTE Standards Community, we’re inviting the broader industry to help shape a solution that works for everyone, regardless of where their services reside or what platform they use.”
Hundreds of proprietary protocols are used today to control media devices, creating a control plane challenge across the media industry. In defining and standardising Catena, SMPTE aims to provide the first and only standardised open-source solution to this challenge. In providing a vendor- and platform-agnostic solution, Catena offers a single secure protocol that is equally suited to controlling very small devices and microservices as it is to controlling the most complex physical devices and services in use by the media industry.
Thomas Bause Mason, SMPTE Director of Standards Development, said, “One of the fundamental challenges facing our industry is managing devices and services across a fragmented infrastructure, and proprietary control protocols are simply not up to the task.
“Catena offers a new model based on open standards, community-driven development, and a pragmatic path to implementation. Designed to address every device, service, and system in any environment, it offers the adaptable, future-proof approach we need.”
The initial suite of Catena documents introduced consists of: ST 2138-00: Catena Overview; ST 2138-10: Catena Model; ST 2138-11: gRPC Connection Type; ST 2138-12: REST Connection Type; and ST 2138-50: Catena Security.
Stan Moote, CTO, IABM, added, “The industry has long needed a common control layer that actually reflects how we operate today — across clouds, platforms, and vendors. Catena offers a standards-based path forward that brings the transparency and scalability needed for smart, efficient resource management in distributed environments.
“It’s encouraging to see this kind of progress being made openly, with broad collaboration through SMPTE and engagement from IABM’s Control Plane Working Group, bringing the supplier community into the process.”
