Readings in Multimedia Computing and Networking captures the broad areas of research and developments in this burgeoning field, distills the key findings, and makes them accessible to professionals, ...researchers, and students alike. For the first time, the most influential and innovative papers on these topics are presented in a cohesive form, giving shape to the diverse area of multimedia computing. The seminal moments are recorded by a dozen visionaries in the field and each contributing editor provides a context for their area of research by way of a thoughtful, focused chapter introduction. The volume editors, Kevin Jeffay and HongJiang Zhang, offer further incisive interpretations of past and present developments in this area, including those within media and content processing, operating systems, and networking support for multimedia. This book will provide you with a sound understanding of the theoretical and practical issues at work in the field's continuing evolution.* Offers an in-depth look at the technical challenges in multimedia and provides real and potential solutions that promise to expand the role of multimedia in business, entertainment, and education. * Examines in Part One issues at the heart of multimedia processes: the means by which multimedia data are coded, compressed, indexed, retrieved, and otherwise manipulated. * Examines in Part Two the accommodation of these processes by storage systems, operating systems, network protocols, and applications. * Written by leading researchers, the introductions give shape to a field that is continually defining itself and place the key research findings in context to those who need to understand the state-of-the art developments.
The emerging technologies of digital video and high-speed networks are combined together in a set-top box to provide a wide variety of value-added services to consumers. The control software in ...set-top boxes includes a real-time multi-tasking operating system with extensive multimedia support. Along with digital TV functionality, the control software provides an easy to use functional interface for set-top capabilities, such as MPEG decoding, high-speed broadband network interface, 2-way communications and graphics. An application-level software called the
navigator performs basic TV functions and has the ability to download and execute interactive multimedia applications from network servers.
We present an adaptive rate-controlled scheduler for heterogeneous applications running on general purpose computers. Our scheduler can effectively support diverse application requirements. It ...employs uniform rate-based sharing. Application heterogeneity is satisfied by partitioning CPU capacity into service classes, each with a different criterion for admission control. As a result, we are able to provide at once guaranteed performance, flexible allocation of rates with excellent scalability and intermediate service classes offering tradeoffs between reserved rate utilization and the strength of guarantees. Our scheduler has been implemented in Solaris 2.5.1. It runs existing applications without modifications. We present experimental results showing the scalability, efficiency, guaranteed performance, and overload performance aspects of our scheduler. We demonstrate the importance of priority inheritance implemented in our scheduler for stable system performance.PUBLICATION ABSTRACT

Multimedia is an increasingly important part the mix of applications that users run on personal computers and workstations. The requirements placed on a multimedia operating system are demanding and ...often conflicting. After studying multimedia characteristics and multimedia system requirements, this paper presents a new operating system for multimedia files and applications and it calls this operating system an Optimal Multimedia Operating System as optimal operating system solution for multimedia applications and files and compare this optimal operating system with three existing operating system: QLinux, Mac osx Leopard, Windows Vista.
