In this report we present a framework for evaluating performance of scheduling preorchestrated multimedia information over broadband integrated networks. We propose a set of Quality Of Presentation (QOP) parameters which quantify the quality of multimedia presentation from user's point of view. The communication of mulltimedia data in a networked environment can affect the desired QOP parameters due to jitter delays in the network. We evaluate trade-offs between QOP parameters and the system resources including channel utilization and buffering at the destination. These trade-offs can be used to develope an optimal transmission schedule for multimedia information.
