Encrypted Media proposal (was RE: ISSUE-179: av_param - Chairs Solicit Alternate Proposals or Counter-Proposals)

Hi all,

We have been collaborating on an API to enable encrypted media in HTML that we think
can be implemented in all browsers and support any container/codec and content
encryption solution without making major changes to the HTML Media element
specification. We think it solves most use cases without being overly large or
complex.

We'd like to get people's feedback on the proposal. It is posted here:
http://dvcs.w3.org/hg/html-media/raw-file/tip/encrypted-media/encrypted-media.html

Many content providers and application developers have said they can't use <audio>
and <video> because HTML lacks robust content protection. Without this functionality,
they cannot move their apps to the web platform. Many consumer electronics are taking
advantage of HTML for both video playback and user interfaces, yet their content
protection solutions are typically tied to the device. We believe that working
towards a common solution will reduce fragmentation between all HTML platforms.
 
This has been raised in the Web & TV Interest Group [1] and mentioned in their
feedback [2]. We believe this extension specification supports the counter proposal [3]
for ISSUE-179 [4]. It demonstrates how to provide additional functionality to the
HTML5 media element without requiring a generic mechanism like <param>.
