Abstract: A method of embedding information in digital content representing media streams. The method includes selecting a set of locations within that digital content representing the media stream to embed information (601), selecting a set of possible alteration to make at those locations (602), and making a subset of the possible alterations. The set of locations and possible alteration is herein sometimes called a “watermark”. The subset of actual alterations that are made is herein sometimes called a “fingerprint”. The method determines a set of locations at which there are alternative versions of digital content (603) representing the same media stream.

Abstract translation: 一种在表示媒体流的数字内容中嵌入信息的方法。 该方法包括选择表示媒体流的数字内容中的一组位置以嵌入信息（601），选择在这些位置（602）进行的一组可能的改变，以及进行可能的改变的子集。 这里的位置和可能的改变在这里有时被称为“水印”。 所做的实际改变的子集在这里有时被称为“指纹”。 该方法确定存在代表相同媒体流的数字内容的替代版本（603）的一组位置。

Abstract: Secure presentation of media streams includes encoding the media streams into digital content, encrypting a portion of that digital content, the portion being required for presentation, in which the encrypted version is substantially unchanged in formatting parameters from the clear version of the digital content. Selecting those portions for encryption so there is no change in distribution of the media stream: packetization of the digital data, or synchronization of audio with video portions of the media stream. When encoding the media stream into MPEG-2, refraining from encrypting information by which the video block data is described, packet formatting information, and encrypting the video block data using a block-substitution cipher. A block-substitution cipher can be used to encrypt each sequence of 16 bytes of video data in each packet, possibly leaving as many as 15 bytes of video data in each packet in the clear.

Abstract translation: 媒体流（110）的安全呈现包括将媒体流（110,111）编码成数字内容（111），对该数字内容（230,231,232）的一部分进行加密，该部分是呈现所需的部分，其中 加密版本在数字内容（111）的清晰版本的格式化参数方面基本上没有变化。 选择这些部分用于加密，使得媒体流的分布没有变化：数字数据的分组，或与媒体流的视频部分的音频的同步。 当将媒体流编码为MPEG-2时，避免加密描述视频块数据的信息，分组格式化信息，并使用块替换密码对视频块数据进行加密。 可以使用块替换密码来加密每个分组中的16个字节的视频数据的每个序列，在清除（260）中每个分组中可能留下多达15个字节的视频数据。

Abstract: A technique of distributing digital content (122) representing media streams (124), and keys (127) for unlocking that content (122), to a user. Content (122) is deliverable to the user separately from licenses (130) to that content (122). Content (122) is delivered encrypted (122). Licenses (130) are delivered designating selected presentation devices (143) owned by the user. The presentation devices (143) include a secure Portion (144), relatively resistant to tampering by the user, in which each presentation device (143) maintains a unique presentation device key (134). The user owns one or more such presentation devices (143), coupled using a local communication link (141) to a local library (142), which maintains a copy of the content in an encrypted form (122). The user can search the library (142) for information generally available about the media stream 142.
