What?

From Henri Sivonen's "What is EME?":

Encrypted Media Extensions (EME) is a JavaScript API for playing DRMed video content in HTML. A DRM component called a Content Decryption Module (CDM) decrypts, decodes, and displays the video. A JavaScript program coordinates the process using the EME API to pass messages between the CDM and a server that provides decryption keys and content.

Why?

Hollywood studios require companies that license movies for streaming use DRM between the streaming company and the end user. On the Web, this has traditionally been done by using the Microsoft PlayReady DRM component inside the Silverlight plug-in or the Adobe Access DRM component inside the Flash Player. As the Web platform gains more capabilities, general purpose plug-ins like Silverlight or Flash can be phased out.
