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.
