On Thursdays the USPTO publishes new pending patent applications. Booth of today's Spotlight Applications address aspects of digital fingerprinting. The first application discloses techniques for advertisement detection and substitution. The second application discloses techniques for restoring program information for clips of broadcast programs shared online, no assignee given.
A television signal substitution system that replaces standard video segments with selected replacement portions. Video segments such as advertisements are detected using techniques such as fingerprinting or manual detection. The detected video segment is replaced with a selected replacement portion and output to an output device.
20090077049, "Restoring Program information for Clips of Broadcast Programs Shared Online," no assignee given.
To restore context information about a clip that was sampled from a broadcast program, the clip is identified by matching a digital fingerprint of the clip against a database of known digital fingerprints taken from broadcast programs. If the clip can be identified, it is then associated with information about the matching broadcast program. The loss of context data about the clip obtained from a broadcast program is thus remedied, enabling media content available online to be more useable for a variety of purposes, such as media searching, automatic broadcast attribution, and targeting advertisements.
