Abstract
A content protection management system that enables interoperability with other Content Protection and DRM technologies. A managed security domain provides a simple, consistent and reliable experience to whole-home network subscribers. The architectural concept for the whole-home network includes an underlying control plane with an overlaying content security control plane running a particular DRM technology.
Claims19
A system providing content delivery to devices over a managed multimedia home network, comprising:
- a domain manager for receiving content, wherein the domain manager includes a first and second conditional access device and a security application;
- and
- a managed client device, coupled to and registered with the domain manager, the managed client device running a security application, the managed client device communicates with the security application in the domain manager;
- wherein the security application of the domain manager and the security application of the managed client instantiate device authentication and content usage rules as an overlay on top of any other content protection scheme;
- and
- wherein the domain manager descrambles and rescrambles the content for distribution to the managed client device and provides the usage rules to the managed client device when the content is acquired from the conditional access device.
A method for providing content delivery to devices over a managed multimedia home network, comprising:
- receiving content at a domain manager, wherein the domain manager includes a first and second conditional access component and a security application;
- requesting content from the domain manager by a managed client device that is coupled to and registered with the domain manager, wherein the managed client device runs a security application, the managed client device communicates with the security application in the domain manager;
- instantiating device authentication and content usage rules as an overlay on top of any other content protection using the security application of the domain manager and the security DRM application client of the managed client;
- and
- wherein the domain manager descrambles and rescrambles the content for distribution to the managed client device and provides the usage rules to the managed client device when the content is acquired from the conditional access device.
A computer readable device including executable instructions which, when executed by a processor, provides content delivery to devices over a managed multimedia home network, by:
- receiving content at a domain manager, wherein the domain manager includes a first and second conditional access component and a security application;
- requesting content from the domain manager by a managed client device that is coupled to and registered with the domain manager, wherein the managed client device runs a security application, the managed client device communicates with the security application in the domain manager;
- instantiating device authentication and content usage rules as an overlay on top of any other content protection using the security application of the domain manager and the security DRM application client of the managed client;
- and
- wherein the domain manager descrambles and rescrambles the content for distribution to the managed client device and provides the usage rules to the managed client device when the content is acquired from the conditional access device.
