FIELD: physics.SUBSTANCE: method comprises phases, during which video bit stream containing a sequence of image frames is received, the error occurrence is determined in the display frame segment, time distribution and spatial distribution of the named error is identified by means of the motion vector information and internal prediction relating a segment, affected by the error, the quality of video bit stream is assessed on the basis of the named error distribution.EFFECT: improvement of accuracy of assessment at the expense of identification of error spatial distribution in the display frame segment.18 cl, 16 dwg |
