Patent ID: 8184163

Claim:
A method for detecting skipped frames between a test video sequence and a reference video sequence, said method comprising: a) identifying a first plurality of segment pairs associated with a test video sequence comprising a plurality of test frames and a reference video sequence comprising a plurality of reference frames, wherein each segment pair in the first plurality of segment pairs comprises a portion of the reference frames and a temporally aligned portion of the test frames; b) for each segment pair in the first plurality of segment pairs, receiving an associated alignment offset and an associated freeze-frame count; c) calculating a segment alignment offset between a first segment pair in the first plurality of segment pairs and a second segment pair in the first plurality of segment pairs, wherein the second segment pair is temporally subsequent to the first segment pair; d) for the first segment pair and each segment pair in a second plurality of segment pairs comprising any segment pair in the first plurality of segment pairs temporally intervening between the first segment pair and the second segment pair, summing the associated freeze-frame counts; and e) subtracting the segment alignment offset from the summed freeze-frame count to form a skipped-frame count associated with the first segment pair and the second segment pair.
