Multimedia communication aims at transferring various forms of data, audio and video simultaneously in a single network. The applications such as videoconferencing, digital TV, multimedia teaching, distance learning and video on-demand make use of multimedia network and communication technologies to provide quality of service (QoS). With the wide variety of different real time system applications we need specific software for those specific real time systems that will meet the requirements of an application. In this paper, we propose the design and development procedures for real time systems using component based methodology. It starts with the requirement analysis of a real time system and continues to provide the functional model of the system and also the environmental design as well. As more and more functions or components needed to be added in designing a software system a modularized and systematic approach becomes not an option. Hence this paper proposes a systematic and procedural approach that will help to build a more reliable and suitable software architecture. This paper also includes a case study – a Multimedia Real time conferencing system, whose aim is to provide a brief demonstration of how to apply the architecture and notations that are presented in this paper.
