  • GRPL provides visual language & XML-based format to define complex rights ‘proofs’
  • Navigates flexible entity-relationship graph when deciding whether to deliver key to secure HLS client
  • Entity-relationship graph created and managed by integration with middleware and business systems
  • Can include all standard DRM concepts like Devices, Users, Domains, Licences, Packages, Assets and any other object required by business model
  • Flexible server-based DRM model reduces client complexity and cost
  • Makes it easier to manage and opens up DRM market to an “Open Systems” model
  • An ecosystem of vendors will promote competition and innovation
HLS encryption flow diagram: the HLS chunker and HLS origin server deposit keys with the key server over HTTPS; the set-top box fetches playlists and AES-encrypted chunks over HTTP and keys over HTTPS
