| 发明名称 | Methods and apparatus for identifying media 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 generating a first signature based on a media content signal, the first signature comprising a plurality of first normalized features, each normalized feature corresponding to a signal peak and located at a temporal location of the signal peak in the audio signal, correlating the first signature to a reference signature comprising second normalized features to obtain an index, and determining that the first signature represents the same media content as the reference signature when the index is greater than a threshold. | ||

| 主权项 | 1. A method to identify media, comprising: generating a first signature based on a media signal, the first signature comprising a plurality of first normalized features, the normalized features respectively corresponding to a corresponding signal peak and located at a temporal location of the signal peak in the media signal; correlating the first signature to a reference signature comprising second normalized features to obtain an index; and determining that the first signature represents the same media as the reference signature when the index is greater than a threshold. | ||
