Towards semantic modeling framework for future service oriented Networked Media Infrastructures

摘要

Architectures that enable the deployment of large-scale Networked Media Infrastructures (NMIs) to support the increasingly diverse range of media applications, as well as the demand for delivery of user-aware media services have become a necessity. Key to the design of such architectures is the implementation of NMIs that are flexible and support reusability of distributed resources. There is also the requirement to provide a unified description mechanism to cater to the heterogeneous nature of media content, service and infrastructure providers' resources, as well as end-user terminals. This paper describes a service-oriented architecture for implementing future high performance NMIs which are capable of supporting emerging beyond High Definition digital media formats. It focuses mainly on a novel semantic modeling framework based on Resource Description Framework (RDF). This novel framework is being developed to equip the proposed architecture with a unified description mechanism and the capabilities to perform dynamic media service composition.
