Methods and apparatus for integrating digital rights management (DRM) systems with native HTTP live streaming

摘要

Methods and apparatus for integrating digital rights management (DRM) systems with native HTTP live streaming. Several methods for integrating a DRM system with HTTP live streaming on an operating system (OS) platform are described. In each of these methods, a manifest is delivered to an application on a device; the application then accesses a remote DRM server to obtain a license and one or more keys for the content. The DRM server enforces the rights of the client in regard to the indicated content. The application may modify the manifest to indicate a method for obtaining the key. The application delivers the manifest to the OS, which uses the indicated method (e.g., a URL) to obtain the key. While similar, the methods primarily differ in the manner in which the OS is directed to obtain the key.
