Abstract: A digital rights management system includes an authentication module and a decryption module. If desired, the modules can be implemented in separate integrated circuits. The authentication module retrieves authentication information for protected content and powers down after the authentication information is retrieved. The decryption module decrypts the protected content based on the authentication information while the authentication module is powered down.

Abstract translation: 数字版权管理系统包括认证模块和解密模块。 如果需要，这些模块可以在单独的集成电路中实现。 验证模块检索受保护内容的认证信息，并在检索认证信息后关闭电源。 解密模块在认证模块断电的同时基于认证信息解密受保护内容。

Abstract: A current mobile multimedia signal time slice is captured using a mobile MM receiver in response to a current mobile multimedia stream-identifying command input. The current mobile multimedia signal time slice contains at least one portion of a currently selected mobile multimedia stream. At least one anticipated mobile multimedia time slice is selectively captured. The at least one anticipated mobile multimedia time slice contains at least one portion of a corresponding anticipated mobile multimedia stream.

Abstract translation: 响应于当前的移动多媒体流标识命令输入，使用移动MM接收机捕获当前移动多媒体信号时间片。 当前移动多媒体信号时间片包含当前选择的移动多媒体流的至少一部分。 选择性地捕获至少一个预期的移动多媒体时间片。 所述至少一个预期的移动多媒体时间片段包含对应的预期移动多媒体流的至少一部分。
