To meet the needs of the next generation of media services, Android 4.3 introduces a modular DRM framework that enables media application developers to more easily integrate DRM into their own streaming protocols, such as MPEG DASH (Dynamic Adaptive Streaming over HTTP, ISO/IEC 23009-1).
Through a combination of new APIs and enhancements to existing APIs, the media DRM framework provides an integrated set of services for managing licensing and provisioning, accessing low-level codecs, and decoding encrypted media data. A new MediaExtractor API lets you get the PSSH metadata for DASH media. Apps using the media DRM framework manage the network communication with a license server and handle the streaming of encrypted data from a content library.
