Application-driven playback of offline encrypted content with unaware DRM module
Abstract:
Application-driven interceptor module enables offline playback of Digital Rights Management (DRM) protected content to work in a same way as online playback. Communications with the DRM module are intercepted by the application-driven interceptor that is aware of the client device's network connection status. When the interceptor application determines that the client device is offline, requests for the protected content, and license/key to the protected content may then be managed by the interceptor application. In one embodiment, the interceptor application may retrieve requests for the key/license from a locally protected data store, and provide the key/license to the DRM module. In this manner, the DRM module may be unaware that its messages are being intercepted, and may then operate the same, unaware of whether or not the client device is online or offline.
