Latest Patents

One of Richard S. Land's latest patents is titled "Method and system for recognition of broadcast segments." This invention relates to producing a signature that characterizes an interval of a video signal representing a picture. The signature is generated based on portions of the video signal that correspond to specific regions of the picture. Additionally, the invention produces a corresponding mask word that includes multiple bit values, each representing the reliability of the signature values. The first signature is formed with values based on the video signal portions, while a second signature is created from shifted portions of the video signal. The values of both signatures are compared to establish the bit values of the mask word.

Another significant patent by Land is "Method and system for producing a signature characterizing an audio." This invention focuses on creating a signature that characterizes an audio broadcast signal for recognition purposes. The signature is based on a comparison of time-displaced frequency band values, each representing a respective frequency band of the audio broadcast signal. The comparison involves a first group of frequency band values and a second group, with the latter representing portions of the audio broadcast signal that were broadcast prior to the first group. A signature is formed based on this comparison.
