Abstract: Disclosed is a method and device for selecting documents, such as Web pages or sites, for presentation to a user, in response to a user expression of interest, during the course of presentation to the user of a document, such as a video or audio selection, whose content varies with time. The method takes advantage of information retrieval techniques to select documents related to the portion of the temporal document in which the user has expressed interest. The method generates the search query to use to select documents by reference to text associated with the portion of the temporal document in which the user has expressed interest, as by using the closed caption test associated with the video, or by using speech recognition techniques.
Abstract: Disclosed are methods and systems for routing T-37 E-mail over an H 323 (VOIP) network. The methods and systems facilitate the obtaining and utilization of data from Gatekeepers with respect to the utilization of Gateways to be utilized to transmit the E-mail from the network over a conventional telephone network to the recipient. They thereby facilitate the choice of a Gateway which is less heavily utilized.
Abstract: The invention is a system for digital watermarking that operates on a conventional digital video stream to etch, on hand, and read, on the other hand, digital watermarks in the stream that do not visibly interfere with the video content. A system according to the invention operates on digital data that has been transformed into the spatial-frequency domain, using inter-block differences between spatial-frequency coefficients to encode the bits of a digital watermark. Using the principles of the invention, it is possible to encode multiple watermark bits between two adjacent blocks, thus providing higher watermark data rates relative to underlying video content.
Abstract: Disclosed is a method and device and computer storage medium for determining whether two pages linked on the World Wide Web are a part of the same World Wide Web site. The method involves examining and comparing the IP addresses of the Web pages, and can also be extended to finding other pages to which a given Web page is linked on the Web, and to determining whether a Web page of interest is part of a Web site with a desired characteristic, such as being part of an electronic commerce site.
