Using XML-based real-time model for distributed real-time multimedia systems

In order to manipulate multimedia objects effectively to users, there has been great demand for multimedia modelling languages which can provide various ways of presentation with multiple multimedia objects. We propose a Web-based XML modelling language called RT-XML, which is capable of expressing the manipulation of distributed real-time multimedia objects. The real-time statements of RT-XML are added to a subclass of XML. RT-XML includes time constraint, scheduling, probabilistic behaviour and qualitative description of multimedia streams. Finally, we present an application of RT-XML for controlling the delivery of multimedia services, which include resource management and real-time capabilities.
