Broadcast information classification system and method

摘要: Method and apparatus for classifying broadcast information first receives the processes it to provide a plurality of low bandwidth analyzed waveforms. The waveforms are used generate spectragram which is then compared with reference spectragrams stored in stage library. queued order their similarity generated spectragram. Next, second patterns, correspond spectragrams, correlated one queueing established previously. A correlation value provided each pattern When determined that exceeds threshold value, recognition declared classified as similar whose threshold. waveform classification may be time warped account speed fluctuations information.
