  • Patent number: 7778417
    Abstract: The present invention provides a means for managing title keys by establishing logical partitions of title keys encrypted with the same binding information. The invention supports delayed and background processing of title keys when binding information changes. This invention supports proper accounting for devices required to recover rebinding processing when devices fail or go offline unexpectedly during processing. The invention uses binding context which represents a set of data that can be used to determine if the binding information used to encrypt a set of title keys is outdated and allow for rebinding to the current cluster binding information level.

  • Patent number: 7778421
    Abstract: An apparatus and a method are provided for selectively accessing digital content carried on a distribution medium such as a physical medium or a broadcast medium. In one embodiment, a plurality of digital content items are encrypted under a plurality of different key management blocks, wherein each key management block is associated with a different set of device keys. The plurality of content items may be provided together on a single distribution medium to devices having assigned device keys, so that devices may selectively access content as determined by the different key management block used to encrypt the various content items and by the device keys assigned to the devices. Depending on the association between the device key and the key management blocks, the decoding device may decode all of the content items, some of the content items, or none of the content items. To provide greater security, each content item may be multiple encrypted using multiple key management blocks per content item.

  • Publication number: 20080196056
    Abstract: A method and business model are provided for augmenting programming content at a remote location, such as a hotel, with the programming content ordinarily provided under subscription to a home location, such as a user's home. A user agreement is formed between a user and a home service provider, delineating the content provided by the home service provider to the home location. A service provider agreement is formed between the home service provider and a remote service provider, delineating content to be broadcast from the home location to the remote location. Local content is selectively augmented by the home content and displayed on a viewing device at the remote location. The user may remotely access settings and functions of a home set top box while at the remote location.
