Claim 41:
42. A non-transitory computer readable medium storing having instructions tangibly stored thereon, wherein the instructions, when executed, cause a system to:
obtain an original media stream;
for each given time window of a plurality of time windows of the original media stream, determine an anomaly state associated with the given time window, the anomaly state being one of a plurality of possible anomaly states; and
store a composite media stream in a memory, each of a plurality of time windows of the composite media stream comprising a corresponding one of the plurality of time windows of the original media stream and an indication of the anomaly state associated with the corresponding one of the plurality of time windows of the original media stream, wherein the anomaly state associated with the corresponding one of the plurality of time windows of the original media stream is based on (i) an estimate of statistical parameters about a normal motion level for the original media stream; (ii) instantaneous measures of a current motion level; and (iii) utilizing statistical hypothesis testing to determine if the current motion level is statistically normal or abnormal.
