Abstract: A UI including a “Guide,” presenting a list of videos, having data fields relating to each entry, possibly including multiple data values for a single data field. When focusing on a single entry, the focused-upon entry is expanded and emphasized. The focused-upon entry is highlighted and centered, while other entries have lesser highlighting and centering. When a data field is selected, the focused-upon data field is emphasized (by highlighting, repositioning, or resizing), while other entries have lesser emphasis. Display changes might appear after a brief delay, or in response to further user command. When entries are sorted on selected data fields, entries with multiple data values for those fields are replicated, and the sorting letter is highlighted. The user can move individually down the list of entries, or skip to the next section with a different data value for a selected field.

Abstract: A UI involving selection and display from a library of videos, including a “Mosaic” mode of operation, in which a primarily visual display is made of information about possible videos, with the effect that a user might select one such video in response to such visual display. The Mosaic includes an two-dimensional array of entries, each of which has visual information for that entry. The Mosaic collects relatively similar entries near to each other in the visual field seen by a user. The focus is centralized and emphasized, and has auxiliary information displayed for further understanding. The array is dynamically rearranged in response to change in focus and metadata about the entries. Relative weighting of that metadata is responsive to user choice. The array includes rows and columns each of which includes all possible entries, but offset by relatively prime values.

Abstract: The invention provides a method and system capable of displaying media streams in a variety of formats on a screen that is dynamically adjustable to conform to displaying the media format that is the object of the media stream. Specifically, the invention allows the viewable area of a display screen (143) to be dynamically resized using masks (161) and sidebars (163), thus the resulting viewable area is optimized for the media stream. A database (110) includes metadata (113) for media presentations. When a user (190) selects a presentation to view, a server (130) associated with the user (190) queries the database (110) for metadata (113) associated with the presentation. The metadata (113) includes aspect ratio and other information for the presentation and sends a response to the server (130) that includes the metadata (113).

Abstract: 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.

Abstract: 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.

Abstract: 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.
