摘要： In various embodiments, a content distribution model is provided in which content providers that own content can distribute their content to third-party content distributors who are unaffiliated with the content providers. The content distributors can, in turn, manipulate the content to provide supplemental content, such as advertising and the like, and then distribute the manipulated content to users who are authorized to consume the content. In this way, content providers are relieved of the responsibility of owning or controlling how such other supplemental content is integrated with their protected content. In this manner, manipulation of the content is delegated to third party content distributors. In one or more embodiments, a ticket-based approach is used as a basis to authenticate that third-party distributors are, in fact, authorized to distribute presentations that include the content provider's content. The ticket-based approach can be used for both server-based verification and client-based verification scenarios.
摘要翻译：在各种实施例中，提供了一种内容分发模型，其中拥有内容的内容提供商可以将其内容分发给与内容提供商无关的第三方内容分发者。内容分发者可以反过来操纵内容以提供诸如广告等的补充内容，然后将被操纵的内容分发给被授权消费内容的用户。以这种方式，内容提供商就不再拥有或控制如何将其他补充内容与其受保护的内容整合在一起。以这种方式，将内容的操纵委托给第三方内容分发者。在一个或多个实施例中，基于票据的方法被用作认证的依据，第三方分发者事实上被授权分发包括内容提供商的内容的演示文稿。基于票证的方法可用于基于服务器的验证和基于客户端的验证场景。

摘要： In one or more embodiments, a license associated with a first piece of content can grant rights with respect to a second and/or additional pieces of content. That is, language that is included in a first license can express a policy that is interpreted by a client-side device. This policy can establish rights with respect to additional pieces of content. Accordingly, policy enforcement with respect to licensed content can take place on the client-side device and can establish how different content is to be played relative to one another.
摘要翻译：在一个或多个实施例中，与第一内容相关联的许可证可以授予关于第二和/或附加的内容的权限。也就是说，包含在第一个许可证中的语言可以表示由客户端设备解释的策略。这项政策可以就额外的内容建立权利。因此，关于许可内容的策略执行可以在客户端设备上进行，并且可以确定如何相对于彼此进行不同的内容的播放。

摘要： A DRM technique involves packaging an advertisement using a data structure that encapsulates a number of advertising segments along with signed information, such as a table of hashes, associated with some of the advertising segments. In one scenario, the data structure and the signed information are separately protected using public key and/or digital signature cryptographic schemes. The advertisement is delivered to a user of a consumer electronic device (CED) separately from delivery of a digital license, which governs user consumption of the advertisement. The digital license includes keys used in connection with the cryptographic scheme, and references a condition to be satisfied with respect to consumption of the advertisement. As advertising segments are verified and consumed by the user/CED, information is recorded and used to determine whether the license condition was satisfied. Satisfaction of the license condition may result in access to program content or additional licenses.

摘要： Portable digital rights for multiple devices is described. In an embodiment, a digital rights management (DRM) system includes a first device with a removable component configured as a token that is associated with a DRM license. The first device also includes a removable memory card that stores protected media content on which the first device can perform actions as permitted by the DRM license. The DRM system also includes a second device that can have the removable component and the removable memory card when removed from the first device and installed in the second device such that the second device can perform the actions on the protected media content as permitted by the DRM license.

摘要： Systems, methods, and/or techniques (“tools”) for binding content licenses to portable storage devices are described. In connection with binding the content licenses to the portable storage devices (“stores”), a host may perform authentication protocols that include generating a nonce, sending the nonce to a store, and receiving a session key from the store, with the session key being generated using the nonce. The store may perform authentication protocols that include receiving the nonce from the host, generating a random session key based on the nonce, and sending the session key to the host.
