Abstract: A media device receives a domain key from a service provider. The media device further encrypts media with a media key and encrypts the media key with the domain key to form an encrypted media token: the protected media key is encapsulated in an encrypted media token. The service provider may then receive the encrypted media token and one or more receiving entity identifiers relating to a receiving entity and ascertain whether the receiving entity is entitled to access media from the media device. If the receiving entity is entitled to access media from the media device, the service provider decrypts the cryptographic media token using the domain key to obtain the media key and providing the media key to the receiving entity. As such, an authenticated receiving entity may obtain the media key necessary to decrypt the media.

Abstract: Techniques and systems are provided for processing user interface content. For example, a server computer can receive a user interface event corresponding to a user interface of a device (e.g., a client device, another server computer, or other device). An application associated with the user interface event can be determined, and an interface model can be generated using the application associated with the user interface event. The interface model defines state information for one or more graphic objects of the user interface. The state information results from the user interface event. The server computer can send the interface model to the device, which enables the device to render the user interface.

Abstract: The disclosure provide methods and content consumption devices that enable a scene, for example a 360° scene, that is larger (i.e. has more pixels in at least one dimension) than a display format of the content consumption device to be displayed. Constituent scene views are received individually by the content consumption device, for example as broadcasts, and are combined, for example stitched together, at the content consumption device to output a part of the scene that fits in the display format. The part of the scene (and hence the required constituent streams) to be displayed are determined by a signal, for example a navigational input from a user, enabling the user to navigate in the scene.
