Implementors should be aware that this specification is not stable. Implementors who are not taking part in the discussions are likely to find the specification changing out from under them in incompatible ways. Vendors interested in implementing this specification before it eventually reaches the Candidate Recommendation stage should join the mailing list mentioned below and take part in the discussions.
Publication as a Working Group Note does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.
This registry is intended to enhance interoperability among implementations and users of encrypted media streams with the
Encrypted Media Extensions (EME) specification [ENCRYPTED-MEDIA]. In particular, this registry provides the means (1) to identify and avoid collisions among initialization data type strings, and (2) to disclose information about initialization data formats accepted by EME implementations to promote interoperability.
2. Organization
The registry maintains a mapping between Initialization Data Type strings and format specifications, which describe the structure and semantics of initialization data. The strings are those used for initDataType values provided by and to Encrypted Media Extensions [ENCRYPTED-MEDIA] APIs.
This registry is not intended to include any information on whether a format is encumbered by intellectual property claims. Implementors and users are advised to seek appropriate legal counsel in this matter if they intend to implement or use a specific format.
Each entry must include a link that references a publicly available specification. It is RECOMMENDED that such a specification be made available without cost (other than reasonable shipping and handling if not available by online means).
Candidate entries must be announced on public-html-media@w3.org(subscribe,
archives) so they can be discussed and evaluated for compliance before being added to the registry.
Per the Encrypted Media Extensions specification, entries MUST be fully specified and support common formats such that instances of the format can be processed in a fully specified and compatible way.
