Analysis of information sources in references of the Wikipedia article "Encrypted Media Extensions" in English language version.
In mobile markets [...] Android has supported MSE since version 4.1, and EME since version 4.3.
Note that IE10 and IE11 on Windows 7 do not have the MSE/EME API available which is required to playback DRM protected video content in HTML5. As a consequence, it is technically not possible for any HTML5-based video player to playback DRM protected content on these browsers in Windows 7.
