Description
Summary:The paper presents an approach to the implementation of network multimedia services using a real time object model. The RTO.k model formalized earlier by K.H. Kim et al. (1994) as a timeliness guaranteed computing model forms the basis of our design methodology. We identified a generic structure of Multimedia Service Object System (MSOS) as a multimedia service programming paradigm. Each Scenario-RTO in an MSOS controls the flow of multimedia streams. A scenario is composed of a set of (time/message triggered) methods. Communications between MSOSs are handled by the Protocol-RTO. To provide an MSOS execution environment, we have developed a middleware named Windows Real Time Object System (WRTOS) on the top of the Windows OS and the MuX platform. The MuX was developed by ETRI to support basic multimedia service interfaces in heterogeneous distributed systems. This approach facilitates the development of multimedia services by easy formalization of services and parameterized service generation.
