Abstract: A local area network 14 comprises a master device 18 and a plurality of network devices 16.1 to 16. n. A method of streaming an asset Asset 1 which is protected with a DRM key DRMK 1 within the local area network 14 comprises causing the DRM encrypted asset [Asset 1 ] DRMK1 to be pre-stored on a database 12 in the network. A request for a license to play the asset is forwarded from a network device 16.1 requiring the asset to be streamed to it to a remote central license server 24. A license message comprising the DRM key required to decrypt the protected asset is forwarded from the backend into said network device 16.1. The copy protected asset [Asset 1 ] DRMK1 is streamed from the database 12 to the network device. The key DRMK 1 is used on the network device to play the protected asset on the network device according to the DRM rules.

Abstract: Mobile device generated sharing of media is disclosed. A user of a first device may obtain transferable limited rights to selected media by initiating transfer of a token from a first digital media service to the first device. The token may then be transferred from the first device to a second device. Upon transfer of the token to the second device a user of the second device may then use the token to access the selected media and direct the streaming of the selected media according to the limited rights included in the token. The limited rights that are transferred may include various limitations on use such as, for example, proximity restrictions on where the first and/or second device must be located for the rights to remain valid, or, restrictions including time or usage limitations. Violations of the restrictions or usage limitations may result in the limited rights being terminated.

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.
