Paper Abstract

In this paper, we introduce a novel technique for the modeling of variable-bit-rate MPEG video streams. This technique is designed to aid multimedia systems researchers interested in using real compressed video data to study the systems they are designing without the overhead of having to digitize and compress the video stream multiple times. Our proposed approach differs from current approaches in that it uses an inexpensive non-inter-coded video capture board to digitize the movie data and then statistically generates MPEG data using the captured movie itself. Our model uses a subsample from the digitized data to create a linear regression model of the target video (both quality and frame pattern). Using this linear regression model, our approach statistically generates the target video. We have digitized and compressed 29 hours of constant-quality MPEG video to verify our pseudo-modeling approach and to allow other researchers to verify this model as well.
