Performance evaluation of multimedia systems with MPEG-2 bitstreams

MPEG-2 has become a compression standard for multimedia applications. Performance analysts, designers, and researchers have been using mpeg-2 bitstreams for evaluating the multimedia performance of their systems. There exist a significant difference in the characteristics and behavior of such bitstreams. The bitstream set, used for performance evaluation, that does not demonstrate such variations results in erroneous evaluations and projections. In this paper, we have proposed a methodology for improving the performance estimations/projections with mpeg-2 data. Our simulation results demonstrate variations in the mpeg-2 bitstreams and the consequence it can have when data from only one of the several classes is chosen for system measurement and evaluation
