Talk:Encrypted Media Extensions

Nitpick corrections
(Not editing the article myself, since I want to avoid COI editing.)

The article contrasts EME-style DRM with DRM that requires "third-party media plugins such as Adobe Flash or Microsoft Silverlight". I suggest replacing "third-party media" with "NPAPI or ActiveX". Here's why:


 * Silverlight isn't third-party in the case of IE.
 * In Chrome (Chrome OS so far), EME-style DRM is implemented as a plug-in, albeit a bundled first-party one. (The Widevine CDM even shows up in the plug-in management UI.)
 * Mozilla announced the intent to implement EME in a way where the DRM component is a third-party plug-in (moreover, it'll be of a plug-in of the "Gecko Media Plug-ins" type making the current wording of the article particularly not apt).
 * In the implementation that Opera demonstrated, the DRM component is from a third-party. (I'm not aware of enough details to judge if it should be characterized as a plug-in.)

The timeline for Safari is incorrect. Safari included prefixed EME with the Key System com.apple.fps in Mavericks. (Try evaluating  in Safari as shipped on Mavericks. That expression does not throw.) MSE support was added in Yosemite.

The bit about Windows 8.1 should talk about IE11 on Windows 8.1 instead of just the OS.

The article is also missing a mention of the deployment on Chrome OS.

How does it work at all?
How does the decryption works? Where are the crypto keys? What is done with the decrypted media content? — So many questions, not one answer in the article. :-( --RokerHRO (talk) 14:14, 24 March 2017 (UTC)
