Abstract: A system for product advertising through a telecommunication network is disclosed. The system comprises an advertising engine and an information depot. The advertising engine comprises an information-extraction tool for acquiring product information, an authoring tool for tracking product images appearing in a display of a video recording, and an augmented-display tool for relating product images appearing in a display of a video recording to respective product information. The information depot comprises a global product directory and overlay directories for a set of video recordings. A number of authoring computers connect to the advertising engine of the present invention as well as streaming video sources and advertising databases to generate content of the information depot. The advertising engine distributes the augmented-display tool to viewers' computers which accesses the video-content directory and the product directory to acquire respective overlay directories and associated product data.

Abstract: A method for identifying object images in a display of a video signal, storing object identification information in an overlay directory, and extracting object information relevant to identified objects from respective information databases is disclosed. Overlay directories from several video signals and associated object information are assembled in an overlay server accessed by computers directly or through a telecommunication network. Object images are selected by users of authoring computers accessing the overlay server. An overlay directory for a video recording indicates temporal and spatial coordinates of images of selected objects, a network address of a video source providing the video recording, descriptions of the selected objects, and addresses of servers providing detailed information of the selected objects. The objects may include commercial products, services, or educational material. The disclosed method therefore may be used for advertising or general information dissemination purposes.

Abstract: An overlay server for illustrative video streaming constitutes a central part of a distributed system for linking content of video recordings to relevant information sources. The overlay server maintains a global object directory including information pertinent to a set of objects and network addresses of external servers providing information relevant to the set of objects. The overlay server further maintains a video-content directory having several overlay directories. Each overlay directory identifies content of a respective video recording from among a set of video recordings and includes a network address of a video-streaming server providing the video recording. The overlay server stores an authoring tool for constructing the overlay directories and an augmented display tool for associating content of a video recording with respective information.

Abstract: A method and apparatus for retrieving information relevant to tracked objects appearing in a display of a video signal is disclosed. The method is performed by a viewing computer having stored thereon an augmented display tool. In response to a user requesting the video signal, a content directory storing content information relevant to the tracked objects is acquired from a video-overlay server. The augmented display tool causes the viewing computer to acquire and display the video signal and record a time measurement and spatial coordinates of each point selected by a viewer using a pointing device. The augmented display tool uses the content directory to find an object identifier corresponding to each selected point and extracts relevant information from a global object directory maintained at the video-overlay server.
