A method and apparatus for identifying repetitively broadcast programs, such as commercial advertisements broadcast on television and radio, detects the occurrence of predetermined events in a video signal and/or in an audio signal, detects a stability condition and extracts a signature from the video and/or audio signal. The signatures and the times of occurrence of the signatures are stored and subsequently compared with reference signatures to identify the program and its time of broadcast. The reference signatures may be obtained by identifying repetitively extracted, unidentified signatures and indexing a recording of the video and/or audio signals to enable the system user to identify the unidentified broadcast program and store the previously unidentified signatures as additional reference signatures in memory.
A method of monitoring a signal comprising the steps of; detecting the occurrence of a predetermined event in the signal; processing the signal at the occurrence if the predetermined event to provide a first series of signal samples; processing the signal a predefined time interval after the occurre
A method of monitoring a signal comprising the steps of; detecting the occurrence of a predetermined event in the signal; processing the signal at the occurrence if the predetermined event to provide a first series of signal samples; processing the signal a predefined time interval after the occurrence of the predetermined event to provide a second series of signal samples; comparing the first and second series of signal samples to detect a stability condition in the signal responsive to an identified predetermined threshold value; extracting a signature from the signal after the occurrence of said stability condition; and storing the extracted signature and a time of extraction thereof.
