  • Publication number: 20230362144
    Abstract: Methods are disclosed for creating a virtual encryption session prior to video streaming content being requested to reduce or eliminate delay in initialization of the encryption session and content delivery to the customer. A virtual session has control word(s) (CW) and virtual entitlement control message(s) (ECM) that are devoid of content specific information. One or more virtual sessions may be stored at an edge device and may be used to encrypt the first portion of a content stream while a content-specific encryption session is being initiated. An edge device may store at least a certain quantity of virtual encryption sessions in anticipation of, for example, receiving multiple content streams.

  • Publication number: 20200226233
    Abstract: Methods and systems for distributed ledger-based digital content piracy deterrence may comprise receiving an indication of a content asset. An indication of a unique identifier associated with a user device may be received. A version of the content asset comprising a digital maker may to be sent to the user device. The digital marker may comprise an indication of the unique identifier of the user device. A distributed ledger record entry comprising an indication of the content asset and the unique identifier of the user device may be caused to be stored on a distributed ledger. The distributed ledger may comprise other record entries indicating other content assets and other unique identifiers associated with other user devices.

  • Patent number: 9930390
    Abstract: Methods, systems, computer-readable media, and apparatuses for providing control word and associated entitlement control message (ECM) functionalities are presented. In some embodiments, a computing device may cache concurrently a first set of control words and a first set of entitlement control messages (ECMs) associated with the first set of control words. The computing device may encrypt a transport stream with a particular control word of the first set of control words. The computing device may insert a particular ECM, of the first set of ECMs, corresponding to the particular control word into the transport stream sent to a device downstream from the computing device. In some embodiments, a computing device may reuse control words and associated ECMs.
