  • Patent number: 10019501
    Abstract: Embodiments of the present invention address deficiencies of the art in respect to data synchronization and provide a novel and non-obvious method, system and computer program product for synchronization log driven data synchronization. In one embodiment of the invention, a data synchronization method can be provided to include assembling a group of initial updates for synchronization, consulting a synchronization log of updates excluded from past synchronizations to determine updates already applied during past synchronizations, removing updates already applied during past synchronizations from a filtered set of updates, and synchronizing the filtered set of updates. In this regard, assembling a group of initial updates for synchronization can include assembling a group of initial updates having a timestamp greater than a timestamp for an immediate past synchronization.

  • Patent number: 8155498
    Abstract: Systems and methods for providing enhanced navigation of stored digital video content based upon an event index. Includes generation and storage of an event index, as well as navigation based on events in the event index. An example system is embodied in a digital video recorder that detects and stores black field and silent frame events for use in locating commercial groups. The commercial groups may be skipped or otherwise navigated based upon data pointers linking the stored events to corresponding locations in the video data file.

  • Patent number: 7735104
    Abstract: Systems and methods for providing enhanced navigation of stored digital video content based upon a content-based index. Includes generation and storage of an index, as well as navigation based on the segments defined by the index. An example system is embodied in a digital video recorder that generates an index for locating commercial groups interleaved with program content in a video presentation recorded from a television broadcast. The commercial groups may be viewed without the intervening program content or otherwise navigated based upon information in the index and one or navigation functions. Example user interfaces and several navigation functions are also provided.

Includes generation and storage of an event index, as well as navigation based on events in the event index. An example system is embodied in a digital video recorder that detects and stores black field and silent frame events for use in locating commercial groups. The commercial groups may be skipped or otherwise navigated based upon data pointers linking the stored events to corresponding locations in the video data file. Generation of the event index may involve comparing a luminance value for each frame to a luminance threshold value for a video presentation. The luminance threshold value may be based upon a transition point between a first group of luminance values corresponding to video content and a second group of luminance values corresponding to transition events, such as black fields.

  • Publication number: 20030172175
    Abstract: An apparatus for standardizing data on two or more electronic devices, comprising: an intermediate server on which is stored a plurality of characterizations, wherein the plurality of characterizations includes a separate characterization for each of the two or more electronic devices; and a service provider that offers one or more back-end software modules to at least one of the two or more electronic devices, and wherein each of the one or more back-end software modules has data associated with it; wherein: a notification module stored on the intermediate server detects a change in the data associated with one of the one or more back-end software modules; as a result of an interaction with one of the two or more electronic devices, the intermediate server receives the change in the data associated with one of the one or more back-end software modules and creates an updated characterization for the one of the two or more electronic devices.
