摘要： 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.

摘要： 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.

摘要： When captured content is detected, the captured content is analyzed to determine whether any portion of the content is subject to digital rights management protection specified for content captured. Responsive to determining that the captured content is subject to a first digital rights management protection, a database is queried to select at least one digital rights management rule associated with a first restricted element specifying at least one first criteria for combining the first restricted element with at least one other element. A determination is made whether the first restricted element is combined with the at least one other element in the captured content. Responsive to detecting the first restricted element is combined with the at least one other element, the captured content rights controller determines a combined digital rights management protection rule reconciling the at least one first criteria for combining the first restricted element with the presence of the at least one other element. The combined digital rights management rule is applied to restrict use of the captured content.

摘要： A captured content rights controller detects a first portion of streaming captured content and a second portion of the streaming captured content after the first portion of the streaming captured content is detected. The captured content rights controller determines whether rendering the second portion of the streaming captured content after the first portion of the streaming captured content is subject to at least one digital rights management protection rule for streaming captured content as specified by at least one owner of at least one restricted element within the streaming captured content captured independent of distribution of the content by the owner of the at least one restricted element within the streaming captured content. The captured content rights controller applies the at least one digital rights management protection rule to restrict rendering of the second portion of the streaming captured content after the first portion of the streaming captured content.

摘要： Provided are techniques for the distribution and control of digital content such that Quality of Experience (QoE) is maintained. Content is protected from when the content is encrypted to when it is used. To ensure the QoE of particular content, a content owner embeds a list of required or preferred components that must be employed to render the content. The content owner's list of required or preferred components specifies specific components “trusted” to correctly process the content. The specified chain of preferred components is compared to possible devices in the system that processes the content. If there are multiple acceptable devices for a specific link, a preference system is employed to determine the device that executed the particular part of the chain. The preference system is based upon a number of factors, such as, but not limited to, performance characteristics, user preferences, expected stability, power requirements and system preferences.

摘要： Provided are techniques for the creation and storage of an archive for binding IDs corresponding to a cluster of devices that render content protected by a broadcast encryption scheme. When two or more clusters are merged, a binding ID corresponding to one of the clusters is selected and a new management key is generated. Binding IDs associated with the clusters other than the cluster associated with the selected binding ID are encrypted using the new management key and stored on a cluster-authorized device in a binding ID archive. Content stored in conformity with an outdated binding ID is retrieved by decrypting the binding ID archive with the management key, recalculating an old management key and decrypting the stored content.
摘要翻译：提供了用于创建和存储用于绑定ID的存档的技术，所述绑定ID对应于呈现由广播加密方案保护的内容的设备的集群。当两个或更多个集群合并时，选择与一个集群对应的绑定ID，并生成新的管理密钥。与除与所选绑定ID相关联的集群之外的集群相关联的绑定ID使用新的管理密钥加密并存储在绑定ID归档中的集群授权设备上。通过用管理密钥解密绑定ID档案，重新计算旧的管理密钥并解密所存储的内容来检索与过时的绑定ID一致的存储的内容。
