Abstract
Methods and apparatuses to detect presence of undesirable video abnormalities during, for example, video ingest or playback. These undesirable characteristics may include an average picture level that is less than a preset threshold value, or static input, in which the content does not change over a significant number of frames. Detection of abnormalities results in an alarm to a system operator. Analysis and alarm may occur automatically during processing of video data streams. The same abnormalities may be detected during playback of the image data.
