Abstract :
The overall process necessary to perform spatial and temporal data composition for a distributed multimedia information system is addressed. With respect to delays introduced through the network, it is found that temporal composition can be most suitably achieved at the workstation. Spatial composition is most effectively performed in a hierarchical fashion as dictated by the availability of system resources. The subsequent composition methodology combines spatial and temporal composition as a network service. Database organizations and data distributions are also investigated, and spatial and temporal composition functions and their composition into the network architecture are discussed. The issue of mapping the composition process onto the network resources as a value-added service is also addressed.<>
