1. Organization

This registry maintains a mapping between HDCP version strings and HDCP specifications as described below.

2. Registration Entry Requirements

  1. Each entry must include a unique HDCP version number, as a string.
  2. Each entry must include reference to the specification(s) for the HDCP version, with a link if the specification(s) are publicly available.
  3. Candidate entries must be announced by filing an issue in the Encrypted Media Extensions GitHub issue tracker so they can be discussed and evaluated for compliance before being added to the registry.
  4. If the Media Working Group reaches consensus to accept the candidate, a pull request should be drafted (either by the registry editors or by the party requesting the candidate registration) to register the candidate. The registry editors will review and merge the pull request.
