As multimedia contents are becoming widely used in ubiquitous computing environments among many application fields, e.g. educational content management, entertainment, and live surveillance, the demand of personalized access to these contents has increased dramatically. Delivering ubiquitous personalized multimedia services (UPMSs) is a challenging task, which relies on many different functions. In this work, we propose a three-layer software platform, called UPmP to support efficient development and deployment of UPMSs. It fulfills the core functions for UPMS including service management, multimedia recommendation, adaptation, and delivery. We adopt component-oriented approach in building the platform. Therefore the configurability of the platform is inherently achieved. A representation model is introduced to hierarchically organize components and describe meta-level information about components. We also present a visual configuration tool together with a XML-based language for the purpose of platform configuration. The experimental results show the UPmP is flexible to be configured under different settings, and the overheads are acceptable.
