Abstract

A computer-implemented method is disclosed comprising: storing a first encrypted multimedia stream on a storage device as the stream is broadcast by a content provider; storing a stream of conditional access data on the storage device, the stream of conditional access data associated with the multimedia stream; and decrypting the first encrypted multimedia stream from a specified point within the encrypted multimedia stream using the stream of conditional access data, responsive to a user request to play back the encrypted multimedia stream from the specified point.
