New patents are issued on Tuesdays by the USPTO. Today's Spotlight Patents concern aspects of digital watermarking and digital fingerprinting. Assigned to AT&T, the first of today's patents address techniques for creating and using watermarked media content in IPTV or iTV networks. Assigned to TiVo, the second patent concerns a multifunction multimedia device using digital fingerprints for content identification and presentation.
8,984,574, "Watermarked media content in IPTV or iTV networks," assigned to AT&T.
Abstract
A method that incorporates teachings of the present disclosure may embedding a watermark in media content for presentation at a rendering device using an editor to associate the watermark with one or more metadata pointers that point to additional media content according to an embedded link of the watermark to generate a group of one or more metadata pointers where the watermark includes an embedded link to additional media content used to modify the media content based on a content exchange between the rendering device and a computer. The method may further include storing the group of one or more metadata pointers, where a selection of the watermark invokes access to the altered media content containing the additional media content associated with the watermark, thereby producing the altered media content at the one or more user devices. Other embodiments are disclosed.8,984,626, "Multifunction multimedia device," assigned to TiVo.
