System and methods for providing live streaming content using digital rights management-based key management

摘要

In the present disclosure, a DRM (in this case IPRM) system may be used to deliver media content keys to a player device in a live streaming environment and take advantage of all DRM related functionalities that come with it, such as proximity control, copy protection enforcement and rights verification. A playlist may be used to deliver a key identifier for encrypted live streaming content.
