Common Media Client Data (CMCD) is a specification produced by the CTA WAVE project. Version 1 is complete and was published in Sept 2020. It is free to use and may be downloaded here. A CMCDv1 Validator library has been built by Montevideo-tech, along with a CMCD Analyzer.
We are now working on version 2 of CMCD. Meetings began on Sept 28, 2023. To get involved, contact CTA WAVE project.
The draft version of CMCDv2 is available in this google doc.
As a reminder, all CTA WAVE meetings are conducted in compliance with the Consumer Technology Association™ Technology & Standards Procedures Manual, EP-23, and the CTA Legal Guides. Participants are expected to have read and be familiar with the requirements in these documents. As described in more detail in the CTA Legal Guides, there shall not be any discussion related to restraint of trade agreements, prices, pricing policies, terms and conditions of purchase or sale, costs, future company plans, boycotting of customers or products, or any other topics that might be considered anti-competitive behavior. Standards, including American National Standards, bulletins, amendments, errata, or other documents, shall be developed in accordance with applicable antitrust and competition laws. Meetings amongst competitors shall be conducted in accordance with these laws. Further details regarding improper activities and programs can be found in Part I of the CTA Legal Guides.
Participants in CTA standards activities are required to disclose knowledge they may have of patents that are essential to the implementation of a standard at the earliest point possible in the standards development process. Owners of intellectual property (also called IP) should provide IP proffers no later than 7 days prior to the vote to approve a standard.
