HTML5 is supposed to set the web free. Free to deliver and shape online media in any web browser. However, several of the standard's greatest champions want to be able to restrict the use of audio and video tags through encrypted media extensions. A draft proposal has been submitted by Google, Microsoft, and Netflix to the W3C -- the curators of HTML5 -- to add encrypted media extensions to the web standard's spec. The proposed system works using a key-based content decryption system controlled by applications, thusly providing the copy protection that so many content owners desire. Naturally, the proposal specifically states that "no DRM is added to the HTML5 specification" if it's adopted, but letting apps lock up audio and video content sure sounds like digital rights management to us. However, there's already some discord amongst the W3C's members as to whether the proposal will work as promised, so its addition to HTML5 is far from assured.
