MPEG4 traffic modeling using the transform expand sample methodology

The transfer of digital video will be a crucial component of the design of future home networking applications. This transfer was made feasible by the advancement of digital video encoding techniques that reduced the bandwidth required for this transfer to a practical level. MPEG4 is an encoding technique that is suitable for home networking applications with its low bit rate. It also has the advantage that allows viewers to interact with encoded objects. In this paper, we present our work that enables the study of MPEG4 properties and performance on the Internet using simulation. We propose a traffic generator that is able to generate traffic that has almost the same first and second order statistics as an original trace of MPEG4 frames that is generated using an MPEG4 encoder. We model and generate this traffic based on the transform expand sample (TES) methodology using TEStool. We present the model and show the performance of the generator in terms of good matching of the characteristics of the modeled trace.
