Widevine is also the default DRM for Android TV Operator Tier, which means operators can go to market without complex DRM integrations. Note that this is not true for the “other Android TV”, based on the Android Open Source Project (AOSP), which can use other DRMs than Widevine but may require more integration and testing.

Adaptive bitrate streaming formats that can be used with Google’s Widevine DRM include MPEG-DASH, Common Media Application Format (CMAF), and HLS. Support for standards-based Common Encryption (CENC; ISO/IEC 23001-7:2016) offers the advantage that a single protected file-set can be streamed to multiple devices, regardless of the DRM system they support, eliminating the need to create and store multiple file-sets.
