| dc.description.abstract | Video teleconferencing is a successful tool in the education and business industry because of its ability to reach a large audience at numerous remote locations. New computer and communications technology allows for advances in teleconferencing capabilities. In this thesis, an analysis of educational teleconferencing requirements is performed to develop viable educational teleconferencing design approaches. These design approaches must consider various transmission means and typical methods of instruction. One design approach is selected and a functional design is performed. The design is evaluated using performance models and the Simscript II.5 simulation language. Curve fitting techniques are applied to observed data to create probability distribution functions used in creating an accurate model. The performance evaluation is used to optimize the transmission protocol and validate the design. The simulation results show that with a 9600 baud transmission rate, the effects of degraded transmission lines, short display times or abnormally large file sizes, have no significant effects on the proper performance of the system. | |
