Abstract
A method and system are provided for securely storing and retrieving live off-disk media programs. Events delineate media segments, each of which are encrypted with a different key so as to be streamable to a remote device via digital living network alliance (DLNA) or HTTP live streaming protocols. Media segments and identifiers for managing the storage and retrieval of such media segments are compatible with live streaming data structures, obviating the need to re-encrypt data streams.
