This paper discusses the work on quantification of video impairments resulting from MPEG compression, together with its application to improve the performance of statistical multiplexing. Impairment metrics are mainly developed as quality measurements, which can be used to trigger post-processing or to quantify its effectiveness. The relevance of the measurements is to improve bit rate allocation in statistical multiplexing of video programs.
