Abstract: User accounts can be linked together to form a group of linked user accounts that can access content items assigned to the other user accounts in the group. A user can download content items assigned to their user account, as well as shared content items assigned to one of the other user accounts in the group of linked user accounts. Use of shared content items can be restricted to client devices running specified versions of an operating system. The key ID tagged to a shared content item can be altered such that the key ID no longer correctly identifies the corresponding DRM key that enables use of the shared content item. Client devices authorized to use shared content items can be configured to recognize that a content item is a shared content item and generate the original key ID form the altered key ID.

Abstract translation: 用户帐户可以链接在一起，形成一组可以访问分配给组中其他用户帐户的内容项的关联用户帐户。 用户可以下载分配给其用户帐户的内容，以及分配给链接的用户帐户组中的其他用户帐户之一的共享内容项。 可以将共享内容项的使用限制为运行指定版本的操作系统的客户端设备。 可以改变标记为共享内容项的密钥ID，使得密钥ID不再正确地识别能够使用共享内容项的相应DRM密钥。 授权使用共享内容项目的客户端设备可以被配置为识别内容项目是共享内容项目，并且从改变的密钥ID生成原始密钥ID。
