Abstract
In a first embodiment of the present invention, a method for performing digital rights management (DRM) for a media item in a device in a home network is provided, the method comprising: retrieving a content directory service (CDS) item for the media item, wherein the CDS item includes a pointer to a rights token and metadata regarding a DRM Interoperability Solution (DIS); determining if the rights token must be downloaded by examining the metadata regarding the DIS; and downloading the rights token by following the pointer if it is determined that the rights token must be downloaded.
Claims20
A method for performing digital rights management (DRM) for a media item in a device in a home network, the method comprising:
- retrieving a content directory service (CDS) item for the media item, wherein the CDS item includes a pointer to a rights token and metadata regarding a DRM Interoperability Solution (DIS);
- determining if the rights token must be downloaded by examining the metadata regarding the DIS;
- and
- downloading the rights token by following the pointer if it is determined that the rights token must be downloaded.
A method for establishing digital rights management (DRM) for a media item in a home network, the method comprising:
- creating a content directory service (CDS) item for the media item, wherein the CDS item includes a pointer to a rights token and metadata regarding a DRM Interoperability Solution (DIS).
A home network device comprising:
- a processor configured to:
- retrieve a content directory service (CDS) item for a media item, wherein the CDS item includes a pointer to a rights token and metadata regarding a DRM Interoperability Solution (DIS);
- determine if the rights token must be downloaded by examining the metadata regarding the DIS;
- and
- download the rights token by following the pointer if it is determined that the rights token must be downloaded.
A content directory server comprising:
- a processor configured to:
- create a content directory service (CDS) item for a media item, wherein the CDS item includes a pointer to a rights token and metadata regarding a DRM Interoperability Solution (DIS).
An apparatus for performing digital rights management (DRM) for a media item in a device in a home network, the apparatus comprising:
- means for retrieving a content directory service (CDS) item for the media item, wherein the CDS item includes a pointer to a rights token and metadata regarding a DRM Interoperability Solution (DIS);
- means for determining if the rights token must be downloaded by examining the metadata regarding the DIS;
- and
- means for downloading the rights token by following the pointer if it is determined that the rights token must be downloaded.
An apparatus for establishing digital rights management (DRM) for a media item in a home network, the apparatus comprising:
- means for creating a content directory service (CDS) item for the media item, wherein the CDS item includes a pointer to a rights token and metadata regarding a DRM Interoperability Solution (DIS);
- and
- means for responding to requests from a home network device with content directory service items.
A program storage device readable by a machine, tangibly embodying a set of computer instructions executable by the machine to perform a method for performing digital rights management (DRM) for a media item in a device in a home network, the method comprising:
- retrieving a content directory service (CDS) item for the media item, wherein the CDS item includes a pointer to a rights token and metadata regarding a DRM Interoperability Solution (DIS);
- determining if the rights token must be downloaded by examining the metadata regarding the DIS;
- and
- downloading the rights token by following the pointer if it is determined that the rights token must be downloaded.
A program storage device readable by a machine, tangibly embodying a set of computer instructions executable by the machine to perform a method for establishing digital rights management (DRM) for a media item in a home network, the method comprising:
- creating a content directory service (CDS) item for the media item, wherein the CDS item includes a pointer to a rights token and metadata regarding a DRM Interoperability Solution (DIS).
