New pending patent applications are published on Thursdays by the PTO. Today's Spotlight Applications concern aspects of digital watermarking and digital fingerprinting. Assigned to Hitachi (JP), the first application discloses a digital watermark advertising content service system. Assigned to Microsoft, the second application discloses techniques for video identification and search.
20130325622, "Digital watermark advertising content service system," assigned to Hitachi (JP).
The present invention provides an advertising content service system including a client terminal equipped with a camera, and a server that provides an advertising content associated with a digital watermark ID received from the client terminal. The client terminal includes a means for reading a digital watermark image embedded in a medium with the advertising content printed or displayed thereon by using the camera, analyzing the digital watermark image, extracting the digital watermark ID from the digital watermark image, and transmitting the digital watermark ID to the server. The server includes a means for acquiring from a database a detail of the advertising content associated with the digital watermark ID received from the client terminal, and transmitting the detail to the client terminal as a request source for display.
20130326573, "Video Identification And Search," assigned to Microsoft.
Systems and methods for identifying and searching video are disclosed. A video search and identification system includes a catalog representing relationships between video, data and/or objects to enable querying and search based on visual representations of video as well as data or other information associated with the video. In one example, the catalog includes video nodes, metadata nodes and card nodes, although additional or fewer node types may be used. A visual-based video identification system is provided to identify content in video sources. An unidentified video source is accessed and visual fingerprints of one or more frames are generated as query signatures for matching against a base set of known signatures. Confidence measures are generated at the bit level to assist in query signature processing.
