Google, Microsoft, and Netflix have proposed Encrypted Media Extensions, which would encrypt HTML5 audio and video files. The proposal would enable applications on the web and elsewhere to use keys to control whether they have access to specific media streams, thereby enabling support for key or Any format of bit can be used under HTML5.
This will eliminate objections from Adobe and other relevant providers regarding copyright restrictions on HTML5 content. Content providers such as paid movie services have faced HTML5 restrictions on local mobile applications. Netflix will have the choice to abandon the Silverlight plug-in, while Google will abandon YouTube Flash content on the Android market, and Microsoft will use HTML5 in the Xbox 360.
However, this proposal has problems at both the technical and company cooperation levels: It will break many standards at once and may hurt some HTML5 supporters.
The W3C said it is considering this proposal, but did not say when it would make a decision. As an unofficial draft, it can be implemented before it is approved.
