Piracy Protection Features included with Microsoft Playready DRM

1. High secure black boxed encrypted playback mechanism which prevents download of raw video. This is currently implementable with HTML5 video player making its adoption smooth. The biggest plus points of Playready DRM now is it natively supports HTML5 video player and DASH streaming protocol. HTML5 video player is increasingly favoured by browsers over Flash-based video playback. In the absence of native HTML5 DRMs content providers had to get users to install a Silverlight plugin or use the Adobe Access DRM through Flash. Both had the negative aspect that they required users to install things to their device.  Also, it produced some security risk with Flash. (which is the reason it is increasingly being phased out by browsers)
2. Blocks any screen capture tools running on Windows Devices. High-quality movies are often recorded by users using screen capture tools. But use of Playready DRM ensures that no software or plugin can do so. Microsoft restricts such usage at the hardware level.

The ultimate endorsement for any Digital Rights Management system is having certifications from Hollywood studios. They have millions of dollars on the line, when they make their content available via online streaming. Hollywood’s Digital Entertainment Content Ecosystem (DECE) endorses Playready’s DRM for streaming videos. Netflix and Amazon Instant Video use Playready for streaming on Edge.
