Design of OSGi Compatible Middleware Components for Mobile Multimedia Applications

This paper studies techniques for the support of user mobility for the delivery of multimedia content like MPEG-2 data in ubiquitous environments. The idea is to devise components forming a service infra-structure for keeping track of the positions of users and display devices in their respective vicinities in order to route content to those devices on demand. The solution though targeted for the domestic environment could be in principal extended to wide area access modalities thus yielding an extended home environment. We describe the service interfaces and validate our findings by showing the OSGi compliant implementation of a follow-me display based on this architecture.
