Latest Patents
One of his latest patents is titled "Method and system for recognition of broadcast segments." This invention relates to a method of producing a signature that characterizes an interval of a video signal representing a picture for use in broadcast segment recognition. The signature is produced based on portions of the video signal that represent corresponding regions of the picture. Additionally, the invention produces a corresponding mask word that includes a plurality of bit values, each representing the reliability of a corresponding value of the signature. The first signature is formed with multiple values based on respective portions of the video signal, while a second signature is formed based on shifted portions of the video signal. The respective values of the first and second signatures are compared, and bit values of the mask word are established based on this comparison.
Another significant patent by David M James is "Method and system for producing a signature characterizing an audio." This invention focuses on producing a signature that characterizes an audio broadcast signal for use in broadcast signal recognition. 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 method involves comparing frequency band values from two groups, where at least part of the signal portions represented by the second group were broadcast prior to those represented by the first group. A signature is formed based on this comparison.
