摘要： Dynamic assignment of rights to content, such as in a closed distribution system. Noting state information generated by an item of current content, and modifying state or rights of new content in response. Pre-loading or dynamically sending new content to the owner of the current content, with rights being enabled only at a later time, in the playback device, with predetermined conditions. In response to current state information, dynamically sending a license for new content from a server. Conditional or dynamic licenses to new content, including a set of rights associated with a class of possible sets of state information. Assignment of limited rights to a content, with support in a secure player to enforce them; for purposes of rental, bonus content, trials and other business models.

摘要： A secure processor assuring application software is executed securely, and assuring only authorized software is executed, monitored modes and secure modes of operation. The former executes application software transparently to that software. The latter verifies execution of the application software is authorized, performs any extraordinary services required by the application software, and verifies the processor has obtained rights to execute the content. The secure processor (1) appears hardware-identical to an ordinary processor, with the effect that application software written for ordinary processors can be executed on the secure processor without substantial change, (2) needs only a minimal degree of additional hardware over and above those portions appearing hardware-identical to an ordinary processor. The secure processor operates without substantial reduction in speed or other resources available to the application software. Functions operating in secure mode might reside in an on-chip non-volatile memory, or might be loaded from external storage with authentication.

摘要翻译： 确保应用软件的安全处理器被安全地执行，并且仅确保授权的软件被执行，监视模式和安全的操作模式。 前者对该软件透明地执行应用软件。 后者验证应用软件的执行是否被授权，执行应用软件所需的任何非凡服务，并验证处理器是否已获得执行内容的权限。 安全处理器（1）看起来与普通处理器硬件相同，其结果是可以在安全处理器上执行为普通处理器编写的应用软件，而无需实质性的改变，（2）仅需要最小程度的附加硬件 这些部分出现与普通处理器相同的硬件。 安全处理器没有大幅降低速度或可用于应用软件的其他资源。 以安全模式运行的功能可能驻留在片上非易失性存储器中，或者可以通过认证从外部存储器加载。
