On Thursdays the USPTO publishes new pending patent applications. Both of today's Spotlight Applications concern aspects of digital watermarking. Assigned to AT&T, the first application discloses techniques for watermarked media content in IPTV or iTV networks. Assigned to NEC (JP), the second application discloses techniques for digital content management and verification.
20130024885, "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.20130022230, "Digital content management system, verification device, program thereof, and data processing method," assigned to NEC Corporation (JP).
Abstract
A digital content management system (1) includes: a digital watermark embedding device (100) which generates embedding information uniquely determined from identification information for tracking use, and embeds a digital watermark into a digital content to be managed, based on the thus-generated embedding information; a digital watermark detection device (200) which generates the tracking information uniquely determined from identification information for verification use, and detects the digital watermark in a digital content to be verified based on the thus-generated tracking information; and a verification device (300) which verifies the identification information for verification use supposed to be used for verifying the digital content to be verified in which the digital watermark was detected.
