While traditional displays networks are typically closed systems, researchers are now beginning to explore the notion of open display networks in which content can be obtained from a wide range of sources. Open display networks have very different properties to closed networks as they need to deal with multiple management domains and conflicting content and scheduling requirements from different stakeholders. A key challenge is to provide an appropriate software infrastructure to support openness at all stages (e.g. content distribution, schedule creation, media playback). In this work we demonstrate a suite of software components that together provide a comprehensive eco-system for open pervasive display networks.
