Thursdays the PTO publishes new pending patent applications. Both of today's Spotlight Applications concern aspects of digital watermarking. Assigned to Digimarc, the first of today's applications discloses techniques for associating first and second watermarks with audio or video content. The second application discloses techniques for synchronising content with live television.
20140373164, "Associating first and second watermarks with audio or video content," assigned to Digimarc.
The present invention relates generally to processing audio or video content. One claim recites a system comprising: a portable device comprising storage and an electronic logic processor, the electronic logic processor configured for analyzing first content stored in said storage to detect a first class of watermarking hidden therein, the first class of watermarking comprising a link between the first content and a user, the first content further comprising a second class of watermarking, the second class of watermarking providing an indication that the first content is protected, in which the second class of watermarking is more difficult to remove from content relative to the first class of watermarking; and a software module for interacting with content files, said software module including instructions to cause an electronic logic processor to control transfer of the first content file to said portable device based on detection and interpretation of the second class of watermarking. Other claims and combinations are provided as well.
20140373043, "System For Synchronising Content With Live Television," no assignee given.
A computer system in which augmentation content can be provided to a client device. A receiver is provided in a server for receiving a live television signal. A matching engine can then identify a segment of television, based on fingerprinting techniques and can determine a time delay between the start time of the segment of television and its identification. A content retrieval unit can then select augmentation content based on the identified segment of television and the time delay, and this can be output to a client device. In this way the augmentation content can be selected so that it maintains synchronisation with live television.
