[PROBLEM]—The match alarms are green when the two input sources are identical. However, they still remain green a long time after one of the sources has changed to a different content.

[SOLUTION]—Make sure the silence, low-motion, and weak correlation alarms for those respective sources are not currently red. Due to the way the fingerprints are generated, silence and still images are not currently supported for comparison. In addition, some contents are more difficult for the Fingerprint Analyzer to compare one with the other. Examples of such contents are: end-of-program credits, repetitive tones (weather summaries), talking heads, etc. In that case, the weak correlation alarms should indicate that the current contents cannot be produce conclusive results, which will come when the contents change to something that can be compared conclusively.
