A multimedia content is usually read-only and composed of multimedia objects with their spatial and temporal specifications. These specifications given by its author can enforce the display of objects to be well organized for its context. When multimedia contents are serviced in network environment by an on-demand basis, the temporal relationship among the objects can be used to improve the performance of the service. This paper models the temporal relationship as a scenario that represents the presentation order of the objects in a scenario and proposes several scheduling methods that make it possible to rearrange the transmission order of objects in a scenario. As a result, system resources such as computing power and network bandwidth can be highly utilized. Since the temporal relationship of a scenario is static, it is possible to reduce the scheduling overhead of a server by pre-scheduling currently servicing scenarios. In addition, several simulation results are presented in order to compare and analyze the characteristics of the proposed methods.
