The KeyOS MultiPlay SDKs

Player Agents for iOS and Android Applications


The KeyOS™ MultiPlay™ SDKs supports both Microsoft PlayReady and Windows Media Rights Manager technologies. Both Microsoft Smooth Streaming (ISMV) and Apple HTTP Live Streaming (HLS) are supported as content delivery methods.


The KeyOS MultiPlay SDKs are pre-integrated with the iOS native media player. For Android, the service includes an integrated hardened media player as well as all the necessary integration documentation and support. Most popular playback functions are supported and we add new functions and features regularly.


Our Service exposes an API for iOS application integration. On Android, an additional JAVA API is provided for application integration. You receive downloadable OS-specific binaries to compile with your device application(s) before you distribute them to your customers.


The downloadable DRM technology provided with the KeyOS MultiPlay SDKs complies with Microsoft PlayReady and Windows Media Rights Manager robustness and compliance rules. The DRM payload is protected with code obfuscation and validation as well as other anti-tampering mechanisms.
