<p>This paper examines the effects that degrading frame rates has on user perception of a video application in a typical Graphic User Interface (GUI) environment. Specifically, experimentation shows that degrading the frame rate, which is a QoS parameter, of a continuous media stream exhibits perceived differences depending on the nature of the application. It was found that degrading the QoS of a multimedia session has different consequences for the network bandwidth required for different distributed multimedia applications, which is directly related to the number of users that can be supported concurrently by a multimedia server.</p> <p>Contact Apteker at the Computer Science Department, University of the Witwatersrand, Wits 2050, Johannesburg, South Africa, e-mail</p>
