PlayReady, by Microsoft, is probably the most influential and broadly supported DRM solution in today’s marketplace. It was introduced in 2008 as a more device portable and standards-centric evolution of the prior Windows Media DRM system. PlayReady has been adapted and extended in various ways since, that point to support streaming vs file download, live vs on-demand, and domain vs personal licenses. At least partly because of its open approach to device licensing, PlayReady has a wide and deep ecosystem that includes implementations on a broad array of devices and operating systems to protect premium content streaming while driving the optimal user experience. Devices and environments that embed PlayReady DRM clients include: The Edge and IE browsers The Windows OS Xbox Most smart TVs Roku and Fire TV streaming devices The license server components of PlayReady have also been widely implemented as part of commercial DRM systems, including EZDRM’s Universal DRM. EZDRM supports both Microsoft PlayReady and Windows Media Rights Manager technologies. Both Microsoft Smooth Streaming (PIFF) and MPEG-DASH (DASH) are supported content delivery methods.
