A Web Services-Based Architecture for Capability-Aware Ubiquitous Media

Abstract

Ubiquitous media aims to provide media services anytime and anywhere. To realize it, one challenge is how to provide customized and dynamic services to a variety of computing devices with different capabilities. This paper presents an architecture, which enables customized delivery of multimedia services. A concept of capability is used to abstract the adaptation-related attributes of computing devices. Capability concerns both the static and dynamic attributes of the computing devices, such as display resolution and remaining battery power. These two classes of attributes can be combined to provide complementary information for customized and dynamic media delivery. As a proof of concept, we have developed a prototype implementation, which is characterized by Web services-based architecture, and capability-aware feature. Our initial experiments show the effectiveness of this architecture.
