Sažetak
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 becomes very important. Subjective methods for convenient television picture quality and impairment assessment given in ITU-R Rec. BT.500-4 were modified and applied to MPEG codec. The test pictures for subjective evaluations were chosen very carefully with different types of movement and including camera operation. These pictures have been taken from video sequences coded with different bit rates. The different bit rates result in different picture qualities. The aim of this paper is to present results of picture quality assessment in relation to impairments from MPEG-1 coding for workstation and personal computer applications where pictures are displayed within a window on a monitor. Statistical analysis of the test results was performed. Based on this analysis the observations and conclusions are given.
