  • Patent number: 7178096
    Abstract: An Internet-connected portal system has a data repository, a data-gathering system, a request processor, a plurality of report algorithms, and a report processor. The request processor receives a request from a user and matches the request to an individual one of the report algorithms. The data-gathering subsystem accesses plural Internet sites associated with the user and extracts raw data therefrom according to needs of the report algorithm. The report processor processes the raw data according to the report algorithm into metasummarized information defined by the report algorithm, and the portal system transmits the metasummarized information as a report to a destination associated with the report request.

  • Patent number: 7158666
    Abstract: A system for presenting a virtual advertisement or other virtual content in a sequences of frames of a video presentation utilizes data identifying a candidate region in the sequence of frames, a pixel signature for the region, the signature comprising a range of R, G, B values for pixels based on a standard deviation from an average value, and stored virtual content, such as an advertisement, to be implanted in the candidate region or regions. In operation, as frames having the candidate region are processed by an integration system, the alternative virtual content is substituted by default for the candidate region, except if a pixel value in the region falls outside the pixel signature range. The result is an ad that appears to be on a surface in the video presentation, as images that come between the ad and the viewer occlude the advertisement. Apparatus and methods for providing the video presentation and data sets for regions and advertisements are disclosed as well.
