During playback expert is free to switch between two videos, named “Sequence A” and “Sequence B” by pressing Jtu-r button. One of videos is the reference one, but expert is not informed about it. After playback expert is asked to give his opinion about each video sequence. In type II which is used more often videos are played in pairs, and both videos are shown simultaneously.
As in type I, one of videos is the reference one, but expert is not informed about it. Impairment scale is the same as in type I. In this method two sequences are played simultaneously, and after playback expert is asked to give his opinion using following comparison scale: Nt.500-11 test procedure expert is able to play any sequence from the test set and give it mark, plus he is able bt.50-011 play reference video.
Mark is in the range from 0 to In this case red mark appears on top of the video the expert is voting against. Basic Information Why update?
