|Abstract:||Mobile devices with multimedia and networking capabilities are quickly becoming ubiquitous through the availability of small notebooks; PDA; and in particular; mobile phones. However; most multimedia systems are still centralized; concentrating all multimedia computing on a single device. At best they deploy a strict client/server architecture mostly for streaming multimedia from some server while processing it locally.|
Ubiquitous computing environments on the other hand require systems that allow multimedia content and processing to be flexibly distributed across different devices that are currently available in a network while supporting dynamic migration between devices as users move or requirements change.
This paper concentrates on the two most important operations for dynamic distributed multimedia: combining two flow graphs so that common processing can be shared between them as much as possible; and – based on this service – reconfiguring a running multimedia flow graph across a network. We use a number of different application scenarios to motivate the basic middleware requirements including device control and distributed synchronization. Finally; we present two key applications and report on results of an implementation of this approach.
