Control Plane Working Group
This group had its initial meeting IBC 2024, meetings continued on Zoom with some Joint meetings with RIS-OSA on Teams. 

PAGE UPDATE: 10 June 2025

Catena suite development progressing in SMPTE

The IABM continues to attend and contribute to the SMPTE Microservices drafting group meetings. The suite will comprise (at least) the following documents:

ST 2138-10 – Catena Model

ST 2138-11 – Catena gRPC Connection method

ST 2138-12 – Catena REST Connection method

ST 2138-19 – Catena Protocol Objects

ST 2138-50 – Catena Security

The plan is to take these key five parts to public Committee Draft. That is a stage in SMPTE document development where the documents are made publicly available to expose them to a much wider audience for scrutiny, comment and trial implementation. Then, any comments received during the public Committee Draft stage will be addressed to improve the documents that will then progress through ballot to publication.
An additional document part, ST 2038-13 Catena WSS Connection Method, will be added if there is found to be a requirement for this method to be used in addition to the gRPC and REST methods.

Progress

At the 9th June meeting, ST 2138-10 was approved to proceed to a 2 week review in the Technology Committee, at which point it will be ready for posting as a public Committee draft. However, the group has decided that all documents in the list above will go to public CD together, so we have to wait for the others to catch up.


Control Plane document review - Deadline May 16th

 We have arranged for our IABM Control Plane group to have a preview of the ST 2138 draft documents before they go into the SMPTE process. Please have a look at the short video below.

This preview will permit you to make frank comments about the draft, so we can assure:

  • areas aren't missing
  • industry overlap has been avoided (as much as possible as per our comparison doc)
  • it is practical to implement for vendors
  • security concerns are met
  • this can provide control and can monitor your products and services

 We don't have much time during this preliminary review process and once it goes into the SMPTE process, all comments and changes need to be formalized, hence the May 16th deadline.

As for comments:

  • if they are general - use this group email to pass around, this way all can comment
  • if detailed, send a marked-up PDF to Chris Lennon, John Naylor, Paul Treleaven. and myself. We can consolidate the details and get them sent around.

Final note - don't be shy! all comments are welcome

The review period closed on 16 May. Comments received were passed on to the SMPTE RIS-OSA group and discussed in a joint meeting today, 21 May 2025.

The RIS-OSA group plans to submit the drafts to SMPTE Standards very soon, with a plan to proceed to Public Committee Draft.

Drafts for comment - comment period now closed:

SMPTE RIS-OSA Draft - Catena Model - For IABM Review Only

SMPTE RIS-OSA Draft - Catena gRPC Connection Type - For IABM Review Only

SMPTE RIS-OSA Draft - Catena Security - For IABM Review Only

NEXT MEETING: TBA.

Contact our CTO, Stan Moote to be added to the group

The IABM has set up this group to enable member companies to discuss and consider what is required to establish a control system for Media Technology that can establish itself as the "universal" control system for our industry.

We are all aware that many such control systems have been put forward in standards bodies, but have not gained traction for a variety of reasons - e.g. too vendor-specific, not well suited to popular programming languages, too confusing/obscure, too heavy on resources.....

Another problem is that control systems have been submitted to Standards Organizations (SMPTE, IEC, AES) without a thorough review of requirements by the vendor and user communities. The standards people have done their job creating the documents, without knowing whether they fulfil the needs of the industry.

Catena has emerged as a possible solution in this space. It is an open-source, open-standard approach to the control plane challenge, which is secure and will scale up to the degree needed of the largest media organizations. This work has been taking place in SMPTE’s RIS-OSA organization, with a goal of getting its documents into SMPTE’s standards community as Public Committee Drafts as soon as possible. Our plan is to assess industry requirements against the work done on Catena.
