摘要： The system comprises a separate unit for calculating quality parameters relating to results obtained from video test sequences by means of the device to be tested and nonlinear as a function of these results. It also comprises a unit for comparing, over time, these parameters and corresponding quality parameters, the latter being associated with reference results relating to video test sequences. The comparison unit produces binary results corresponding respectively to the quality parameters by means of predetermined tolerance margins, thereby allocating to each of the binary results corresponding to one of the quality parameters a first value when the quality parameter associated with the device to be tested remains within the tolerance margin around the quality parameter associated with the reference results, over time, and otherwise, a second value. Application to an IRD.
