  • Patent number: 8583829
    Abstract: Systems and methods for providing reduced object data to devices. Context can be received from a device. The context can be used to determine what portion of an object is used by an application executed on the device. The object can be reduced prior to communicating the data to the device, thereby conserving resources associated with the device.

  • Patent number: 8528019
    Abstract: A method of selecting, storing and delivering desired audio/data/visual information includes the steps of determining viewing preferences of a viewer and receiving a first group of audio/data/visual signals, for example, broadcast and cable television signals or internet-based signals. Based on the first group of audio/data/visual signals, a second group of audio/data/visual signals, which is a subset of the first group of audio/data/visual signals, is identified. The second group of audio/data/visual signals is selected based on the association of EPG data for each signal with the viewing preferences of the viewer. Content data is then extracted from the second group of audio/data/visual signals and compared with the viewing preferences. The content data may include, for example, closed-captioned text, EPG data, audio information, visual information and transcript information.

  • Patent number: 7369680
    Abstract: A system and apparatus are disclosed for modeling patterns of behavior of humans or other animate objects and detecting a violation of a repetitive pattern of behavior. The behavior of one or more persons is observed over time and features of the behavior are recorded in a multi-dimensional space. Over time, the multi-dimensional data provides an indication of patterns of human behavior. Activities that are repetitive in terms of time, location and activity, such as sleeping and eating, would appear as a Gaussian distribution or cluster in the multi-dimensional data. Probability distribution functions can be analyzed using known Gaussian or clustering techniques to identify repetitive patterns of behavior and characteristics thereof, such as a mean and variance. Deviations from repetitive patterns of behavior can be detected and an alarm can be triggered, if appropriate.

  • Patent number: 6973256
    Abstract: There is disclosed an apparatus for detecting program highlights in a video program. The apparatus comprises: 1) a keyword detection circuit for detecting a location of a selected keyword in an audio track of the video program; and 2) an audio signal energy level detection circuit for determining an audio signal energy level of the audio track proximate the detected location of the selected keyword and comparing the audio signal energy level to a predetermined threshold. The audio signal energy level detection circuit, in response to a determination that the audio signal energy level exceeds the predetermined threshold, identifies the detected location of the selected keyword as a program highlight.

  • Patent number: 6859803
    Abstract: An apparatus and method for conducting exclusive and inclusive metadata searches to identify and select multimedia programs. The apparatus of the invention including a metadata search controller that compares user specified search words with metadata words to find programs that meet user specified search criteria. The metadata search controller executes an inclusive metadata search to search for matches between a user specified search word and a metadata word that is related to the user specified search word in a word pair contained within a word pair database. The metadata search controller calculates a rank value for each program that is found by a metadata search and creates a ranked list of such programs.

  • Patent number: 6829778
    Abstract: A method of limiting the number of presentations or observations of information items, such as advertising images, that are repetitively distributed among a plurality of transmitted materials is presented. In accordance with the principles of the invention, information items are compared, using identifiable properties, to similarly identified information items that have been previously received and stored in a dynamically created and updated data base of information items. When a count of number of the occurrences of a selected information item with same, or substantially similar, identifiable properties achieves a selectively set threshold value, the selected information item is precluded from being presented or observed in subsequent transmissions or broadcasts.

  • Patent number: 6819863
    Abstract: For use in a video signal processor, there is disclosed a system and method for locating program boundaries and commercial boundaries using audio categories. The system comprises an audio classifier controller that obtains information concerning the audio categories of the segments of an audio signal. Audio categories include such categories as silence, music, noise and speech. The audio classifier controller determines the rates of change of the audio categories. The audio classifier controller then compares each rate of change of the audio categories with a threshold value to locate the boundaries of the programs and commercials. The audio classifier controller is also capable of classifying at least one feature of an audio category change rate using a multifeature classifier to locate the boundaries of the programs and commercials.

  • Patent number: 6778224
    Abstract: A method for placing overlay elements in images of a digital video so that desirable viewing areas of the images are not occluded by the overlay element, the method includes extracting frames from the video, each of the frames defining an image which may have one or more desirable viewing areas. For each frame, an area is selected in the image for placing an overlay element and the percentage the overlay element overlaps the desirable viewing areas is determined for the selected area. The overlay element is placed in the selected area if the percentage is below a maximum allowed predetermined percentage of overlapping. If it is not, one or more other areas in the image are selected and/or the size, shape, aspect ratio of the overlay element is changed until a position and/or size, shape, aspect ratio is found which minimizes occlusion of the desirable viewing areas in the image.

  • Publication number: 20030126267
    Abstract: A method and apparatus are disclosed for restricting access to electronic media objects having objectionable content. The disclosed access control system prevents a user from accessing objectionable content based on an analysis of the audio or visual information associated with the content. For example, image processing techniques are employed to dynamically detect nudity, violence, or other identified inappropriate content in an image associated with an electronic media object. In addition, speech recognition techniques can be employed to dynamically detect one or more predefined stop words in audio information associated with an electronic media object. When a user first attempts to access an electronic media object, the audio or visual content (or both) of the electronic media object is analyzed to determine if the electronic media object contains any predefined inappropriate content. The inappropriate content may be defined, for example, in accordance with user-specific access privileges.

  • Publication number: 20030023974
    Abstract: The present invention provides techniques for tracking objects in sports programs and for selecting an appropriate camera view. Generally, in response to preferences selected by a user, a particular object in a sporting event is tracked. Not only is the object tracked, but statistical data about the object is compiled and may be displayed, depending on user preferences. Additionally, a user can select particular cameras to view or can select certain portions of the playing field to view.
