Methods and apparatus for watermark outage detection

Abstract

Methods, apparatus, systems and articles of manufacture are disclosed for watermark outage detection. Example methods include evaluating an onset time and duration of a detected watermark outage based on a model of expected watermark outages to determine whether the detected watermark outage corresponds to at least one of the expected watermark outages represented in the model. Example methods further include generating an alert in response to determining the detected watermark outage does not correspond to at least one of the expected watermark outages included in the model, and suppressing the alert in response to determining the detected watermark outage corresponds to the at least one of the expected watermark outages represented in the model.

What is claimed is: 
     
         1 . A watermark outage monitoring apparatus comprising:
 an outage analyzer to evaluate an onset time and duration of a detected watermark outage based on a model of expected watermark outages to determine whether the detected watermark outage corresponds to at least one of the expected watermark outages represented in the model; and   an alert generator to generate an alert in response to the outage analyzer having determined the detected watermark outage does not correspond to at least one of the expected watermark outages included in the model, the alert generator to suppress the alert in response to the outage analyzer having determined the detected watermark outage corresponds to the at least one of the expected watermark outages represented in the model.
