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.

Abstract: A method is provided for creating an encrypted data file (700) from a data file having a sample entry box and a media data box. The sample entry box has description information therein. The media data box includes media data therein. The method includes: receiving the data file; encrypting the media data within the media data box with an encryption key; replacing the sample entry box with an encoded box (302); creating a sinf box (702) within the encoded box (302); creating a frma box (306) within the sinf box (702); and creating an schm box (704) within the sinf box (702). The schm box (704) indicates the type of formatting of the encrypted media data. The encoded box (302) does not include an initial counter that may be used to decrypt the encrypted media data.

Abstract: A method for DTCP to HLS conversion is provided that starts with a standard DTCP Protected Content Packet (PCP) structure. The PCP payload data is chunked at defined chunk boundaries. Each chunk is then appended with a pad to be compatible with HLS. An HLS playlist is then provided using the PCP header with identification of the chunks and a keytag. The chunk is encrypted with a DTCP key calculated by the DTCP standard using: (a) copy control bits; (b) a nonce, and (c) an exchange key ID. Relevant PCP header fields are provided in the keytag for the HLS playlist supporting the transaction that enables calculation of the DTCP content key to enable later decryption of the chunks. The system further provides a revised HLS GET for DLNA to enable trick play seek operations to be performed on the converted HLS.

Abstract: A method is provided for enrolling and authenticating an attendee of an event or activity so that content can be delivered to a mobile device associated with the attendee. The method includes receiving an identifier of a mobile communication device associated with an authorized attendee while the attendee and the mobile communication device are in a venue at which the event or activity takes place. The mobile communication device is registered by storing the identifier in a database of authorized attendees who have entered the venue. Entitlement credentials are communicated to the mobile device that are to be further communicated from the mobile device to a content server when requesting event or activity related content therefrom.

Abstract: There is a performing of digital rights management (DRM), operable in an offline mode with respect to a communications network. The performing includes identifying a stored rights object associated with a stored asset. The stored rights object includes reporting duration information associated with the stored asset. The performing also includes determining, utilizing a processor, whether a transmission of an early status message is a successful communication based on an early status message determination. If a failure in communicating the early status message is determined, utilizing the stored asset. The performing may also include transmitting an early status message and/or later status message after identifying the stored rights object. There is also a performing of digital rights management (DRM) associated with a DRM system and operable in an offline mode with respect to a communications network. There are also client devices, communicating systems, computer readable mediums and protocols.
