Encrypted Media Extensions; HTML Canvas 2D Context, Level 2 Drafts Published

The HTML Working Group has published two documents today:

  • 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.
  • A Working Draft of HTML Canvas 2D Context, Level 2. This specification defines the 2D Context for the HTML canvas element. The 2D Context provides objects, methods, and properties to draw and manipulate graphics on a canvas drawing surface.

W3C Invites Implementations of CSS Masking Module Level 1

The Cascading Style Sheets (CSS) Working Group and the SVG Working Group invite implementation of the Candidate Recommendation of CSS Masking Module Level 1. CSS Masking provides two means for partially or fully hiding portions of visual elements: masking and clipping. Masking describes how to use another graphical element or image as a luminance or alpha mask. Clipping describes the visible region of visual elements. The region can be described by using certain SVG graphics elements or basic shapes. Anything outside of this region is not rendered. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. Learn more about the Style Activity and the Graphics Activity.
