Abstract:
1. A method for evaluating video quality of a video stream comprising the steps of: a) calculating, for at least a first frame of a series of frames from said video stream, a true value of at least one video quality-related parameter associated with said first frame; b) calculating a predicted value of said video quality-related parameter for at least a second frame out of said series of frames, the prediction being based on said true value associated with said first frame; c) calculating a true value of said video quality-related parameter associated with said second frame; and d) judging the video quality of said second frame based on the difference between true and predicted values of the at least one video quality-related parameter associated with said second frame, wherein the steps a) to c) are carried out for a plurality of video quality-related parameters, and the judging step d) is based on the differences between true and predicted values of all said parameters.
