Abstract
Methods and apparatus for determining increasing robustness of media signatures are disclosed. An example apparatus includes a characteristic analyzer to analyze a media signal based on a signature algorithm to identify a comparison between a first characteristic and a second characteristic that does not satisfy a threshold; and a characteristic enhancer to adjust at least one of the first characteristic or the second characteristic to satisfy the threshold.
Claims22
An apparatus to enhance characteristics of a signature, the apparatus comprising:
- a characteristic analyzer to analyze a received media signal based on a signature algorithm to identify a first comparison between (A) a first characteristic of the received media signal and (B) a second characteristic of the received media signal not satisfying a threshold;
- a characteristic enhancer to, in response to identification of the first comparison not satisfying the threshold, adjust at least one of the first characteristic or the second characteristic to create an enhanced media signal for which a subsequent comparison between the first characteristic and the second characteristic satisfies the threshold;
- and
- a transmitter to transmit the enhanced media signal to a media output device.
(canceled)
A method to enhance characteristics of a signature, the method comprising:
- analyzing, by executing an instruction with a processor, an input media signal based on a signature algorithm to perform a first comparison of a first characteristic of the input media signal and a second characteristic of the input media signal;
- determining whether the first comparison satisfies a threshold;
- when the first comparison does not satisfy the threshold, adjusting, by executing an instruction with the processor, at least one of the first characteristic or the second characteristic to generate an enhanced media signal for which a subsequent comparison between the first characteristic and the second characteristic satisfies the threshold;
- and
- transmitting the enhanced media signal to a media output device.
(canceled)
A tangible computer readable medium comprising instructions which, when executed, cause a machine to at least:
- analyze a media signal based on a signature algorithm to perform a first comparison of a first characteristic of the media signal and a second characteristic of the media signal;
- determine that the first comparison does not satisfy a threshold;
- adjust at least one of the first characteristic or the second characteristic to generate an enhanced media signal for which a subsequent comparison between the first characteristic and the second characteristic satisfies the threshold;
- and
- output the enhanced media signal to a media output device.
