Patent ID: 8284931

Claim:
A method of distributing content using a distribution point, the method comprising: providing a stream of content to the distribution point; receiving a sequence of initialization vectors for the stream of content, the initialization vectors representing settings associated with corresponding portions of content, the settings enabling a decryption engine to decrypt the corresponding content portions using a key; receiving, from an application server, an indication that a request from a client device to access the stream of content is supported; receiving, from the client device and across a communications network, the request to access the stream of content; enabling, based on receiving the indication, the client device to access the stream of content in a connection between the client device and the distribution point; accessing, from within the request, a time mark with a temporal description of a portion of the stream of content should be requested by the user; relating the time mark to the sequence of initialization vectors; and generating an instruction to transmit at least one of the initialization vectors to the client device in a first metadata message.
