摘要： Streaming compressed digital hypervideo received upon a digital communications network is decoded (decompressed) and played in a client-computer-based "video on web VCR" software system. Scene changes, if not previously marked upstream, are automatically detected, and typically twenty-one past scenes are displayed as thumbnail images. Hyperlinks within the main video scene, and/or any thumbnail image, show as hotspots, with text annotations typically appearing upon a cursor "mouse over". All hyperlinks--as are provided and inserted by, inter alia, the upstream network service provider (the "ISP")--may be, and preferably are, full-custom dynamically-resolved to each subscriber/user/viewer ("SUV") upon volitional "click throughs" by the SUV, including retrospectively on past hypervideo scenes as appear within the thumbnail images. Hyperlinking permits (i) retrieving information and commercials, including streaming video/hypervideo, from any of local storage, a network (or Internet) service provider ("ISP"), a network content provider, and/or an advertiser network site, (ii) entering a contest of skill or a lottery of chance, (iii) gambling, (iv) buying (and less often, selling), (v) responding to a survey, and expressing an opinion, and/or (vi) sounding an alert.

摘要： Streaming digital hypervideo including copious embedded hyperlinks is distributed upon a digital communications network from a hypervideo server, normally an Internet Service Provider, to multitudinous client subscribers/users/viewers (client SUVs). Some or all of the client SUVs receive the same hyperlinks at the same place in the streaming hypervideo. Some small fraction of the client SUVs selectively volitionally exercise a fraction of the total hyperlinks, causing an access in the background of the unfolding hypervideo across the digital communications network to yet another server commonly called a "Video On Web server", or "VOW server". The VOW sever interprets each hyperlink request in consideration of (i) the identity of the exercising client SUV and, most commonly, (ii) additional data of a demographic, socioeconomic, credit, viewing preference, security and/or past hyperlinking history nature. The VOW Server supplies each hyperlink-exercising client SUV with a potentially custom hyperlink --normally in the form of a network universal resource locator (URL) or an index to a file of URLs--while keeping track of commercially useful data regarding the client SUV response(s). Each client SUV uses its own associated received URL to retrieve a potentially unique resource. The resource can be internal, such as an executable software program, but is normally located somewhere on the network and is typically in the nature of tailored and/or targeted advertisements, messages of personal or local or temporal pertinence and/or urgency, and/or the results of contests or lotteries. Hypervideo hyperlinks are thus dynamically resolved during streaming network communications to support full custom hyperlinking by each of multitudinous networked client SUVs.

摘要： A tracking software module for tracking a moving image entity in a video display has an interface for receiving and processing a video data stream while the video presentation provided by the data stream is presented on a display as a series of bitmapped images having a moving image entity to be tracked. There is in the module a graphical user interface usable by an editor for creating, selecting and centering a predefined matrix of signature pixel positions on the moving entity to be tracked in a first frame of the video presentation, and for initiating a tracking process. A determination function determines the color values of the signature pixels in the first frame and stores the values as an image signature. An estimation function assumes a next position for the moving entity, and a test function determines the color signature of the signature pixels at the assumed position and at a plurality of test positions in the immediate vicinity of the assumed position and tests the determined values against the color signature recorded for the entity. Finally a recording function accepts the position wherein the pixel signature most closely matches the image signature; in each frame, and a data stream synchronous with the input data stream and having centerpoint coordinates frame-by-frame for the moving entity is provided as a result.

摘要： 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. Methods are provided for selecting candidate regions and for implanting virtual content in various embodiments.

摘要： 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. In some cases there is an aggregated-data database in the data repository storing aggregated data retrieved for specific users periodically, and the request processor checks the aggregated-data database for needed data before requiring the data-gathering system to retrieve data from the associated Internet sites. In the instance that the needed data is stored in the aggregated-data database, the report is prepared from the aggregated data. Reports can be in a mix of text and graphic formats.
