Paper Abstract

This paper aims to describe the digital TV and HDTV codecs as variable bit rate sources to be transmitted on ATM networks. The bit rates will be studied and modeled at different time- scales ranging from the sub-image level (a few microseconds) up to the program level (several hours). At the lowest level corresponding to the microscopic time constants of the network, the cell interarrival times will be considered. At higher levels corresponding to the macroscopic time-scales of the image encoding algorithm, the bit or cell rates will be considered as counting processes over different time spans. To validate the theoretical approach, an experiment has been set up to process with a digital TV codec 25 hours of actual time TV images recorded on D1 tapes. The bit rates and the cell interarrival times have been collected and Statistics will be carried out to validate the proposed models.
