    Abstract: A Headend system including a encoder to encode input data yielding a plurality of data packets, each of the packets having a header and a payload, a post encoding processor to identify ones of the data packets having a payload with a suspected known plaintext, and modify at least some of the identified packets, and an encryption processor to encrypt at least some of the data packets yielding encrypted data packets. Related apparatus and methods are also described.

    Abstract: A system can include a reconciliation engine configured to evaluate metadata in a given manifest file of a plurality of manifest files generated for redundant copies of a given media asset. The metadata describes a condition of a given chunk of media content in one of the redundant copies of the given media asset. The system can also include a manifest modification function configured to modify the given manifest file for the given chunk of media content in response to the reconciliation engine detecting that the given chunk of media content is damaged based on the evaluation of the metadata associated with the given chunk of media content in the given manifest file.

    Abstract: In one implementation, a method performed by a content server with one or more processors and non-transitory memory includes: receiving a first view request from a first client device; determining a first view group associated with the first client device in response to receiving the first view request; identifying a first view hierarchy based on the first view group, where the first view hierarchy includes a first plurality of pointers to a first plurality of content sub-tree hierarchies associated with content items and the first view hierarchy also includes a first order schema; obtaining the first plurality of content sub-tree hierarchies based on the first plurality of pointers; and transmitting display data associated with a first user interface to the first client device based on the first order schema and the first plurality of content sub-tree hierarchies.

    Abstract: In some implementations, a method includes establishing a communication channel with a server via an internet protocol (IP) network interface. The method also includes communicating client private data with the server via the communication channel. The method further includes transmitting one or more interest messages to the server via an information centric networking (ICN) network interface based on the client private data. In other implementations, a method includes establishing a communication channel with a client device via an internet protocol (IP) network interface. The method also includes communicating client private data with the client device via the communication channel. The method further includes receiving one or more interest messages from the client device via an information centric networking (ICN) network interface.
