20100146629, "Content protection system compatibility in home networks," assigned to Samsung (KR).
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.
20100146630, "Method and device for exchanging digital content licenses," assigned to Thomson.
Exchange of Digital Rights Management protected content between two devices without the need for a third party. Each user marks a license as unusable and the devices the trade licenses. A user then instructs the device to import the received license. The device verifies that a license has been rendered unusable and only then erases the unusable license and enables the device to use the new license. The content associated with a license may be traded before or after the license exchange, and may also be downloaded from a third party. Also provided is a device for exchanging licenses.
