A Platform for Context-Aware and Digital Rights Management-Enabled Content Adaptation

This article presents a scalable and modular platform for contextaware adaptation of multimedia content that is governed by digital rights management (DRM). This platform adopts several new approaches, such as (1) combining the use of ontologies and lowlevel context to drive the adaptation decision process, (2) verifying and enforcing usage rights within the adaptation operations, and (3) incorporating multifaceted adaptation tools to provide a wide range of on-the-fly and on-demand adaptation operations to suit various dynamic requirements.
