Thursdays the PTO publishes new pending patent applications. Both of this week's Spotlight Applications concern aspects of conditional access systems such as cable TV and IPTV. Assigned to Comcast, the first application discloses a reconfigurable access network encryption architecture. Assigned to Digital Keystone, the second application discloses techniques for for conditional access and digital rights management
20140108782, "Reconfigurable Access Network Encryption Architecture," assigned to Comcast.
An access platform or other network elements can include multiple line cards configured to encrypt data. The platform and/or each of the line cards may receive encryption management data that conforms to a predefined encryption management data interface. The encryption management data received by a particular line card may be generated by a conditional access system device and converted to conform to the encryption management data interface by an encryption manager. Line cards may alternatively be configured for connection to separate encryption hardware components. Line cards may include a block of field programmable gate arrays or other type of programmable hardware that can be configured to execute an encryption module.
20140041046, "Systems and methods for conditional access and digital rights management," assigned to Digital Keystone, Inc.
Conditional access (CA) and digital rights management (DRM) in digital media delivery, processing, and storage systems. Methods and apparatuses are provided for managing digital rights under the protection of multiple CA and/or DRM systems. Some embodiments provide secure and robust methods for bridging multiple DRM systems in the digital media content distribution and playback systems. The present invention simplifies content repurposing, after it has been bridged to a secondary DRM system, but still under the control of the original DRM system.
