MPEG-2,as an international coding standard, has introduced an era of digital video. With this technology, video signal can be efficiently handled as a compressed digital video data. However degradation in picture quality is caused by this compression process and has been widely concerned because it is very new for human eyes and sometimes so annoying. Therefore an objective quality assessment scheme for degradation by digital compression has been regarded as an crucial issue and research activities on this field have been recently accelerated. In this paper, research trends and standardization activities of objective quality assessment scheme are described. And also we have proposed the three-layered bottom-up noise weighting model, and its' implementation is described.
