摘要： A method of embedding information in digital content representing media streams. The method includes (1) selecting a set of locations within that digital content representing the media stream to embed information, (2) selecting a set of possible alterations to make at those locations, and (3) making a subset of the possible alterations. The set of locations and possible alterations 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 representing the same media stream, such as one being the original and one being an alternative version of the same digital content, herein sometimes called the “original movie” and the “alt-movie,” or herein sometimes called the “original block” and the “alt-block” for a particular block in the digital content representing the media stream.

摘要： Distributing information, including the steps of watermarking the digital content, distributing the digital content using a multi-source system, and partially fingerprinting digital content at each stage of moving information from a point of origin to the viewer. “Adaptation” of the digital content to the recipient includes maintaining the digital content in encrypted form at each such intermediate device, including decrypting the digital content with a key unique to both the device and the specific movie, selecting a portion of the watermark locations into which to embed information, embedding fingerprinting information into those locations sufficient to identify the recipient, and encrypting the fingerprinted digital content with a new such key.

The method includes (1) selecting a set of locations within that digital content reprensenting the media stream to embed information, (2) selecting a set of possible alterations to make at those locations, and (3) making a subset of the possible alterations. The set of locations and possible alterations 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 representing the same media stream, such as one being the original and one being an alternative version of the same digital content, herein sometimes called the “original movie” and the “alt-movie,” or herein sometimes called the “original block” and the “alt-block” for a particular block in the digital content representing the media stream.

摘要： A system including: (a) a media reader including a read element for physical media, the physical media including digital content representing at least one media stream, the digital content being maintained in a protected form; (b) a storage element coupled to the media reader, the storage element using a storage mechanism different from the physical media, the storage element non-evanescently storing the digital content in the protected form; and (c) a playback device coupled to the storage element, the playback device receiving the digital content and outputting analog, digital, or analog and digital audiovisual content for presentation. The digital content is stored in the storage element in the protected form, sent from the media reader to the storage element in the protected form, sent from the storage element to the playback device in the protected form, and output by the playback device in a second protected form.
