PlayReady is Microsoft's DRM system, used on Windows, Edge, Xbox, and a large share of smart TVs and set-top boxes. Alongside Widevine and FairPlay it is one of the three DRMs a multi-DRM platform must support, and it dominates the living-room device ecosystem — many TV and STB manufacturers ship PlayReady as their built-in DRM.
Like the others, PlayReady supports hardware-backed security levels (e.g. SL3000 for hardware-protected HD/4K versus SL2000 for software), and platforms must honor the device's level when deciding what resolution to serve. It works with Common Encryption (cenc and cbcs) so the same encrypted segments can be shared with Widevine.
PlayReady evolves over time and device support shifts with it — for example, the 2025–2026 Samsung PlayReady migration changed which clients and security levels are valid on certain TVs, a reminder that DRM support on smart-TV fleets is a moving target that requires ongoing review.
