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 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.

Selection and presentation of media streams, in which presentation is not limited by order imposed by the digital content representative of those media streams, in response to bookmarks and watchpoints settable and usable by a user. Bookmarks reference a location within the media stream, not necessarily pre-selected and possibly dynamically selected, in which a presentation can be started or restarted therefrom. Watchpoints reference a location within the media stream, or a presentation state for the media stream, in which an action can be triggered thereby. Bookmarks and watchpoints provide a general technique for presenting selections from media streams in response to metadata.
摘要:
A containment device for personnel, animals or objects to be transported in a vehicle so as to avoid cross-contamination, and comprising an envelope (11) having a size and shape approximating to, for example, the rear seating area of a vehicle and having one or more closable panels (12) for access to and removal from the envelope. The flexible envelope (11) is readily transformable between a collapsed and compact condition for storage and an expanded condition for deployment within a vehicle, thus to be readily usable, and in some cases re-usable, and avoiding the conventional method of wrapping the interior surfaces of the vehicle in impermeable sheeting.

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.

摘要:
The invention provides a method of recovering from de-synchronization attacks includes registering original and altered digital content using nonlinear transformations to iteratively attempt to provide better-approximated registration. Approximation occurs at more than one level of granularity, by selecting among a greater number of possible transformation functions at each step. Transformations and comparisons might be conducted directly on pixel values, on coefficients for a set of basis wavelets, or on some transformation of the original and altered digital content. A human operator might assist this process, such as by suggesting transformations or providing evaluation of the degree of registration. Upon resynchronization, embedded identifying information in the original digital content is recovered.

摘要:
The invention provides a method and system capable of allowing users to complete collections of objects without unwanted duplication thereof. The system automatically, and in response to user direction, determines if objects are available that would complete a user's collection. The system can automatically purchase and obtain delivery of objects identified as being needed to complete a collection. The system allows a user to statically define and derive the parameters of a desired collection of objects and can create, and suggest to the user, collections of which the user already has a portion. The system includes functionality that provides user-definable collections.
