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 to identify media content includes receiving a reference signal corresponding to known media content and generating a reference signature based on the reference signal. The method further includes generating a plurality of sums based on peaks in the media signal and identifying one or more signal peaks based on the generated sums. The method then generates a second signature based on a plurality of normalized curve features, wherein each normalized curve feature corresponds to a signal peak at the temporal location of the signal peak, and determines whether the media signal corresponds to the reference signal based a comparison of the reference signature and the second signature.
