Picture impairments in digital video systems are different from those that occur in analogue systems and depend on the methods of coding and redundancy reduction employed. With the increasing applications of MPEG coding, the assessment of MPEG coding impairments becoems very important. Sujective methdos for convenient television picture quality and impairment assessment given in ITU-R Rec. BT.500-4-were modified and applied to MPEG codec. The aim of this paper is to present results of picture quality assessmetnin relation to impairments from MPEG-1 coding for worksation and personal computer applications where pictures are displayed within a window on a monitor. Statical analysis of the test results was performed. Based on this analysis the abservations and conclusions are given.
