CEDIA Leads Recommended Practice Efforts

David Meyer | Jan 26, 2021


2021 marks a significant elevation for CEDIA in the world of industry standards. Back in August 2020 it was announced that CEDIA had become an ANSI-recognized Accredited Standards Developer. The next goal was for CEDIA to take responsibility for the administration of the joint CEDIA/Consumer Technology Association (CTA) R10 working groups, as the CTA had been responsible for running them to date. We’re pleased to report that this has taken effect as of January 2021, with CEDIA now leading the way.

In case you’re not familiar, R10 is the codename given to the Residential Systems Committee. Its purpose is to establish standards and recommended practices for the design and installation of residential technology systems. This supports manufacturers, systems designers, and integrators to ensure the highest levels of professionalism and technical excellence are promoted and implemented.

R10 is composed of working groups (WGs) of expert volunteers, such as WG1 for Audio, and WG3 for Video. Other groups are assembled as needs arise. Resulting recommended practices were titled by the CTA as Consumer Electronics Bulletins (CEB). For example:

  • CTA/CEDIA-CEB22 Home Theater Recommended Practice: Audio Design, and
  • CTA/CEDIA-CEB23-B Home Theater Video Design (the “B” on the end indicates a revision).

With the change in management comes a more intuitive naming convention, changing from Bulletin to Recommended Practice. As such, each new title prefix will change from CEB to RP. Also, as standards and recommended practices are typically reputed as rather gruelling documents, a new layout is designed to encourage readability and navigation. After all, the power of such a document lies with it actually being used -- and regularly.

New Publications

The first publication under CEDIA’s leadership is CEDIA/CTA-RP28 HDMI System Design and Verification Recommended Practice. You may have heard this spoken about on CEDIA podcasts and webinars over several months, referring to it as CEB28. This is the very same document, simply changed from CEB28 to RP28, debuting in the new, fresh format. Its development has been a huge effort from R10 WG3 for some two-and-a-half years, and we’re confident it will prove to be an invaluable resource for integrators globally.

Also on the go is the revision of CEB22 by R10 WG1. This is progressing very well with an awe-inspiring group of some of the industry’s greatest minds in audio. If you haven’t listened already, check out the CEDIA Podcast “Best Practices Update (2020_25b)” from 2020 to learn more. When the working group wraps, instead of the document being named CEB22-A to denote the update, it will launch instead as CEDIA/CTA-RP22 Multi-Channel Audio Room Design Recommended Practice. Watch this space.

Lastly, following the release of RP28 there’s no rest for WG3 as they launch straight into the revision of CEB23-B (last updated 2017). Most notably, this will need to add provision for HDR video, as well as a plethora of other advancements including increasing resolutions and frame rates. Following the same pattern, expect this to develop in due course as CEDIA/CTA-RP23.

Why Do Standards Matter?

With all this talk of recommended practices, standards have hardly gotten a mention. Remember, the primary difference between a standard and a recommended practice is encapsulated in “shall” versus “should.” That is, a standard defines rules whereas a recommended practice is just that: a recommendation. Both are equally important.

Throughout 2020 CEDIA has consolidated the relationships between education, certification (also now with independent ANSI accreditation), and workforce development. Standards and recommended practices weave through all of these. Walt Zerbe, CEDIA’s Snr Director of Technology and Standards describes it as “the base of the pyramid.”

It’s important to note that R10 will still remain a valued collaboration between CEDIA and the CTA. We’d like to take this opportunity to acknowledge and thank the CTA for their years of leadership in these efforts, and look forward to continuing to work together to the benefit of the industry.
