This paper describes a general methodology for constructing probabilistic source models of long sequences (full length movies) of full-motion compressed VBR (variable bit rate) video. This methodology is illustrated with empirical data and applied to a series of simulation studies. The empirical data used in the modeling process as well as in the simulation studies was obtained by encoding a set of four full length movies with two different implementations of the MPEG-4 standard. The target bit rates selected were 100, 200, and 300 Kbps with a frame rate of 30 fps. These encoding programs incorporate adaptive rate algorithms, which try to preserve the quality as much as possible, while at the same time trying to maintain the set target rate. This process generates a video compressed signal with a relatively low varying rate, which in turn allows for a more efficient bandwidth allocation and multiplexing process. The procedure for the creation of the probabilistic traffic models includes: data acquisition of frame size and scene duration; data modeling using histogram representation; and modeling with standard probability density functions. These models can be used to perform efficient and accurate simulations of broadband telecommunications networks in the transmission of medium-high quality compressed video. These encoding algorithms have been selected as the object of study in this paper due to their extended use around the world (over 70 million users) and their impact on video transmission on the Internet. |
