    摘要: A system and method of transferring digital rights from a first device to a second device. A target rights management object is transferred from the first device to the second device. A probabilistic data structure is created that identifies each of a class of rights management objects that are present on the first device. The probabilistic data structure is employed to determine whether the target rights management object is present on the first device. The target rights management object is utilized on the second device in response to a determination through employment of the probabilistic data structure that the target rights management object is not present on the first device. The target rights management object and its state are returned to the first device in response to a determination through employment of the probabilistic data structure that the target rights management object is present on the first device.

    摘要: A local area network (504) for providing Media Provider control and user privacy when distributing media content to the local area network (504). The local area network (504) comprises media devices (510-514) and a proxy (528). The media devices (510-514) provide a description of the capabilities of the media devices (510-514) to a Media Provider (506) in response to receiving a query for the capabilities of the media devices (510-514) from the Media Provider (506). The media devices (510-514) also receive media content directed to the media devices (510-514) from the Media Provider (506). The media content includes content objects based on the capabilities of the media devices (510-514). The proxy (528) translates between generic device names known to the Media Provider (506) and physical device addresses corresponding to the media devices (510-514).

    摘要: A method of an existing media device for distributing a media key to a new media device joining a local area network or revoking an existing media key. For distributing a media key, a set of key generation counter (“KGC”) values are received from the media devices (1010). Each value is then voted on based on the network keys utilized by the existing media device (1012). Next, all votes for each value are gathered from the media devices (1012). A popular values is determined from the set of values (1014). To revoke a media key, a NONCE is encrypted with the network key (1104). The encrypted NONCE is then distributed to media devices of the local area network (1108). Next, votes are gathered from the media devices of the local area network (1110). All votes are received from media devices that are able to decrypt the NONCE using the media key.

    摘要: A digital security system (100) for distributing media content to a local area network (104). The system (100) comprises a media provider (106), media devices (110-116) for receiving media content from the media provider (106) and a remote agent (108) for communicating with the media provider (106) and the media devices (110-116). The media provider (106), or associated third party, has encrypted media content and a content key corresponding to the encrypted media content. Each media device (110-116) has content storage for receiving the encrypted media content, and key storage for receiving the content key. The remote agent (108) obtains the content key from the media provider, (106) encrypts the content key with a network privacy key, and send the encrypted content key to the media devices (110-116). When the media devices (110-116) receive the encrypted media content from the media provider (106), they will be able to decrypt the encrypted content key using the network privacy key and decrypt the encrypted media content using the decrypted content key.

    摘要: Method and apparatus for transferring protected content between digital rights management systems is described. One aspect of the invention relates to importing content from an upstream digital rights management (DRM) system into a device in a downstream DRM system. Data is received that associates at least one device in the downstream DRM system with a rights issuer module (RIM). Authenticity of the data is verified as originating from an entity in a trust hierarchy of the device. If the data is authentic and the device is one of the at least one device associated with the RIM, a ciphertext version of the content and a corresponding content license is accepted from the RIM.

    摘要: An architecture for dynamic IP address management is disclosed. The architecture includes a gateway (GW) coupled between a private IP network and a public IP network. A dynamic host configuration processor (DHCP) is operatively coupled to the GW. A network address translator (NAT) couples to the GW. Lastly, a processor, operatively coupled to the GW and the DHCP, is provided for dynamically assigning to a private IP network subscriber equipment an external IP address and a corresponding IP address hold time as a function of an application to be performed. Assignment of the external IP address and a corresponding IP address hold time is in response to a) a request for accessing the public IP network by a subscriber equipment of the private IP network to perform the application, or b) a request for accessing the private IP network by an entity of the public IP network. The external IP address is selected from a prescribed number of external IP addresses available to the private IP network.

    摘要: A media device (812) for tracking usage of content distributed to media devices (806-812) of a local area network (802). A memory (906) of the media device (812) stores a content usage counter (918) associated with media content (816) of the media device (812). The transceiver (902) of the media device (812) communicates content usage counters (918) among other media devices (806-810) of the local area network (802). The processor (904) of the media device (812) identifies a highest content usage counter having a highest value among the content usage counters (918) of the particular media device (812) and the other media devices (806-810). The processor (904) also determines whether the highest content usage counter is less than a maximum allowable content usage counter for the local area network (802). The transceiver (902) notifies the other media devices (806-810) that media content (816) will be used if the highest content usage counter is less than the maximum allowable content usage counter.
