Abstract

Digital audio and video data are different from traditional media in their time-criticalness and high bandwidth requirements. These requirements and the fact that typical multimedia applications perform only few operations on the continuous-media data suggest the use of new techniques for data handling in distributed, integrated, digital multimedia systems. This paper proposes a system software structure which encapsulates the processing of continuous-media data into stream handlers of a real-time environment. This environment is controlled by traditional non-real-time functions for resource, buffer and continuous-media data stream management. On top of this system, distributed multimedia applications can be built.
