New pending patent applications are published on Tuesdays. Both of today's Spotlight Applications concern aspects of digital fingerprinting. Assigned to Disney, the first application discloses techniques for a program verification and decision system. Assigned to Snell Advanced Media (GB), the second application discloses techniques for comparing video sequences using fingerprints.

Abstract
Embodiments herein describe a content distribution system that verifies a media presentation (or portions thereof) using a broadcast schedule. In one embodiment, the content verification system evaluates the media presentation to identify a unique identification data for the presentation such as a fingerprint or watermark. Using the broadcast schedule, the content verification system can identify what content the media presentation should (or is expected) to contain. The content verification system can retrieve a previously stored unique identifier from a database corresponding to the content identified using the broadcast schedule. If the stored unique identifier matches the unique identifier derived by the content verification system, the system verifies the content in the media presentation is correct. The verified media presentation can then be transmitted to a content distribution network--e.g., a broadcast network or video-on-demand provider.

Abstract
A first sequence of video fingerprints at a first image repetition rate is compared with a second sequence of video fingerprints at a second, different image repetition rate. A converted sequence of fingerprints is generated from the first or second sequence of fingerprints by forming a combination of the values of a number of neighbouring fingerprints. The combination is a weighted average based on the temporal location of the respective neighbouring fingerprints in the first sequence of fingerprints with respect to the fingerprint in the converted sequence. A correlation is then performed between the converted sequence of fingerprints and the other sequence of fingerprints.
