Communications and Distributed Systems Support for Multimedia

Operating System Support for Distributed Multimedia

Multimedia applications place new demands upon processors, networks and operating systems. While some network designers, through ATM for example, have considered revolutionary approaches to supporting multimedia, the same cannot be said for operating systems designers. Most work is evolutionary in nature, attempting to identify additional features that can be added to existing systems to suppor...

Integrated System Support for Distributed Multimedia Databases

The introduction of multiple media into distributed databases raise a variety of new problems. Database management systems also have to deal with multimedia related problems which they share with many other system components including communication systems, operating systems, file systems and storage servers. So far these problems are addressed by each system component individually. A consequen...

Operating System Support for Distributed Multimedia

We have been investigating an end system architecture to support networking with quality of service guarantees. For user level protocol code in our architecture to access the network, we have designed a kernel]user interface. The interface targets three areas for improvement: reduced copying, reduced reliance on explicit kernel]user interactions, and provision of rate-based flow control. In thi...

Operating system support for multimedia systems

Distributed multimedia applications will be an important part of tomorrow’s application mix and require appropriate operating system (OS) support. Neither hard real-time solutions nor best-effort solutions are directly well suited for this support. One reason is the coexistence of real-time and best effort requirements in future systems. Another reason is that the requirements of multimedia app...
