Methods and apparatus for identifying media content using temporal signal characteristics

摘要

Methods and apparatus to identify media content using temporal signal characteristics are disclosed. An example method includes generating a reference signature based on a reference signal corresponding to known media, generating sums based on peaks in a media signal corresponding to media, identifying signal peaks based on the generated sums, generating a second signature based on normalized curve features, wherein the normalized curve features respectively correspond to the identified signal peaks at a corresponding temporal locations of the corresponding signal peak, and determining whether the media signal corresponds to the reference signal based on a comparison of the reference signature and the second signature.

1. A method to identify media, comprising:
generating, by executing an instruction with a processor, interval sums based on peaks in a media signal received at a monitored site corresponding to media; identifying, by executing an instruction with the processor, signal peaks based on the generated interval sums; generating, by executing an instruction with the processor, a signature of the received media signal based on normalized curve features, wherein the normalized curve features respectively correspond to the identified signal peaks at corresponding temporal locations of the corresponding signal peak; and determining, by executing an instruction with the processor, whether the media signal corresponds to a reference signal based on a comparison of a reference signature and the signature of the received media signal.
