Abstract
Methods and apparatus for identifying audio/video content using temporal characteristics of a signal are disclosed. The disclosed apparatus and methods detect a plurality of signal features of a media signal derived from audio/video content and calculate time intervals between a plurality of those signal features to generate signatures. The signatures are then used to identify the audio/video content.
