<p>PROBLEM TO BE SOLVED: To speed up error detection processing for evaluating quality of reproduction or recording of data by equipment.SOLUTION: An information processor has an input part, a storage part, and a control unit. The input part is composed of a plurality of reproduction units arranged along a time axis and is configured in the way that testing data generated by a testing content in which the number of feature points the reproduction unit has monotonously increases or monotonously decreases for prescribed difference as a reproduction time passes being read by equipment to be evaluated and processed is inputted. The storage part stores difference about related to the difference of the feature points. The control unit calculates the number of feature points of the two adjacent reproduction units in the testing data respectively and determines whether or not the difference in the calculated number of feature points is the same as the stored difference, so that an error in the testing data is detected.</p> |
