摘要： A system and method is disclosed for allowing content providers to protect against widespread copying of their content, while enabling them to give their customers more freedom in the way they use the content. In accordance with one embodiment, content providers identify their content as protected by watermarking the content. Consumers use compliant devices to access protected content. All of a user's compliant devices, or all of a family's devices, can be organized into an authorized domain. This authorized domain is used by content providers to create a logical boundary in which they can allow users increased freedom to use their content.

摘要： A recording device for digital data streams, such as digital TV broadcasts or digitized music, stores copies of program content encrypted by a key unique to the recording device. Distribution of program content is thus discouraged, since intelligible playback of program content would not be obtained on another recording device, which would have a different key. To reduce manufacturing complexity which would result from requiring all bits of a key to inhere in hardware, a first portion of the key inheres in hardware and a second portion is selected from among several candidates residing in a memory device, the key being determined by combining the first and second portions according to predetermined rules. The second portion is reselected at predetermined intervals from among the candidates. Only payload portions of packets are encrypted while header portions are left in the clear in order to facilitate ancillary functions of recorder such as fast forward, fast rewind, and program search.

摘要翻译：用于诸如数字电视广播或数字化音乐的数字数据流的记录装置存储通过记录装置唯一的键加密的节目内容的副本。因此，节目内容的分发是不鼓励的，因为在具有不同密钥的另一记录设备上不能获得节目内容的可理解的回放。为了降低制造复杂度，这是由于要求硬件中的所有位都产生的，硬件中的密钥的第一部分和第二部分从驻留在存储器件中的几个候选者中选出，该密钥通过组合来确定第一和第二部分。第二部分以候选者之间的预定间隔被重新选择。为了便于诸如快进，快退和程序搜索的记录器的辅助功能，只有报头部分被清除才能加密分组的有效载荷部分。
