    Abstract: A method and a user device are disclosed for securing streaming content decryption. The method includes receiving at the user device a manifest for requested content, the manifest providing a Content Encryption Key (CEK) that is encrypted using a first public Key Encryption Key (KEK), a corresponding first private KEK being stored in secure storage on the user device; decrypting, inside a secure processing zone on the user device, the CEK using the first private KEK to create a decrypted content key; decrypting, inside the secure processing zone, requested content using the decrypted content key to form decrypted content; and providing the decrypted content to a decoder on the mobile user device.

    Abstract: Presented is a television and methods for decrypting digital data, which is encrypted using one of a plurality of different encryption techniques. A television can receive a digital content stream from a service provider. The digital stream includes the digital content, a decryption module, and metadata. A television can further extract the decryption module as instructed by the metadata from the digital content stream. A television can further decrypt the digital content with the extracted decryption module and a decryption key.

    Abstract: A method of controlling delivery of video programs from video distribution equipment to video receiver devices includes receiving messages at the video distribution equipment from a mobile terminal operated by a user. The messages contain user defined identifiers that are associated with equipment identifiers of different ones of the video receiver devices. The user defined identifiers are stored associated with the equipment identifiers in a subscriber account. Delivery of video programs from the video distribution equipment to the video receiver devices is controlled in response to commands received from the mobile terminal which request delivery of identified video programs to identified ones of the user defined identifiers. Related video distribution equipment and mobile terminals are disclosed.

    Abstract: A client device for media playback includes a user-installable media client application which implements the client-side of a digital rights management (DRM) system. The client device employs secure boot and verifies the user-installed application. The application is hardened against reverse engineering, and it utilizes a special API provided by the client device to tie into the secure boot, bridging the gap between the secure boot and the client-side of the DRM system contained within the application.
