1. A method for determining accuracy of sport-related information extracted from a time sequence of digital video frames that represent a sport event, wherein the extracted sport-related information includes an attribute that changes over the time sequence, the method comprising:
detecting by a computing system, based on the extracted sport-related information, a pattern of change of the attribute over the time sequence wherein detecting the pattern of change of the attribute comprises detecting a particular change of the attribute, and wherein the computing system comprises a processing unit;
making a determination, by the computing system, of whether the detected pattern of change of the attribute over the time sequence is an expected pattern of change associated with the sport event wherein making the determination comprises making a determination of whether the particular change corresponds to an increase of the attribute or rather to a decrease of the attribute;
if the determination is that the detected pattern of change of the attribute over the time sequence is the expected pattern of change associated with the sport event, then, responsive to making the determination, the computing system taking a first action that corresponds to the sport-related information being accurate; and
if the determination is that the detected pattern of change of the attribute over the time sequence is not the expected pattern of change associated with the sport event, then, responsive to making the determination, the computing system taking a second action that corresponds to the sport-related information being inaccurate.
