The HTML Working Group has published a Working Draft of Encrypted Media Extensions. This proposal extends HTMLMediaElement providing APIs to control playback of protected content. The API supports use cases ranging from simple clear key decryption to high value video (given an appropriate user agent implementation). License/key exchange is controlled by the application. This specification does not define a content protection or Digital Rights Management system. Rather, it defines a common API that may be used to discover, select and interact with such systems as well as with simpler content encryption systems. Learn more about the HTML Activity.
