Technologies discussed in this book include those required for distributed multi-media messaging. There is a growing need to manage widely distributed data in a timely and effective manner. The goal of the book is to help students of computer science to learn about the design compo-nents of a real-world multimedia solution for an enterprise. The book is divided into four major groupings of chapters that present relevant technologies-development methodologies, data modeling, and design-in a congruous manner.
The end-of-chapter exercises encourage students to apply what they have learned through actual design and implementation. Professionals will enjoy exploring and building upon new concepts and methodologies presented in this book. Multimedia Systems Design: An Introduction. Chapter 1 presents our basic definition of the various data elements and application sources associated with multimedia and the requirements of the universal multimedia application.
We introduce the object types as well as specialized technologies used in multimedia systems. Th is chapter also introduces multimedia standards and compression and decompression technologies. Group 2 Key Technologies for Multimedia Systems Group 2, comprising Chapters 2, 3, 4, and 5, presents the key technologies consisting of input and output technologies, compression and decompression techniques, and storage technologies. A coded example shows how compression and decompression are performed.
Chapter 4 is a detailed discussion of techniques, standards, and key design issues for input and output technologies, including display systems, image scanners, digital voice and audio components, and full- motion video cameras.
Group 3 Architectural and Multimedia Application Design Issues Group 3, comprising Chapters 6, 7, 8, 9, and 10, presents a detailed discussion of the architectural and design issues that determine the functionality and the design strengths of a distributed multimedia system. In Chapter 7 we discuss data flow control and other application design issues, including virtual reality for multimedia systems.
Chapter 8 provides a discussion of authoring systems and user interface issues for multimedia systems. Chapter 9 presents an analysis of the design issues for multimedia messaging technologies i ncluding e-mail interface and addressing standards such as VIM, X. In Chapter 10 we discuss the key design issues for distributed multimedia systems.
The discussion includes design issues for multiserver networks, organizing a distributed multimedia database, managing objects in a distributed database, replication of objects, and storage optimization. Group 4 Design Approaches to Advanced Multimedia Systems Group 4, comprising Chapters 11 and 12 presents a design methodology to prepare readers of the book for adopting an advanced methodology for modeling the requirements and defining objects, and presents a step- by-step approach to multimedia systems design along with real coded examples.
In Chapter 11 we present a detailed design methodology for examining the requirements of the enterprise and the application, the current architecture and feasibility issues, and performance requirements. This chapter also presents a detailed system design methodology.
In Chapter 12 we present design issues for a real-world example of a multimedia system application. This example will help the reader understand and put to immediate use the knowledge gained from this book. In addition, a glossary of terms is provided for reference along with a complete detailed index. The exercises at the end of each chapter encourage readers to apply what they have learned through actual design and implementation. References, where applicable, are identified in footnotes.
A number of new concepts and methodologies are being presented in this book. The authors hope that the reader will enjoy exploring them and building upon them as much as the authors enjoyed developing them. We will find it especially rewarding if we have succeeded in promoting new ideas and avenues in the advancement of distributed multimedia applications technology. Acknowledgments Producing a book is a team effort. A number of people contributed their time and effort in reviewing the contents and bringing this book into production.
We would like to thank everyone who contributed to this effort by sharing their time and taking interest in our work and encouraging us to continue.
In particular, we would like to thank Michael Gretzinger for reviewing this book and his helpful comments. The effort put in by a number of our colleagues in performing detailed reviews and using their hands-on object-oriented design knowledge for critiquing the text for its final cleanup is greatly appreciated.
Special thanks are due to the senior management at Lotus for their encouragement and support, as well as for the wonderful opportunity to use some of the design concepts developed for this text as the basis for the architecture and design of commercial products.
Our special thanks go to Mr. Paul Becker, our publisher and editor, for his patience, guidance and encouragement at all times, as well as for steering it through to production. We also acknowledge the efforts of Betty Letizia and John Morgan for managing the production of this book, and Raymond Pajek and Cathy Kemelmacher, for their painstaking efforts in typesetting and copy editing this text.
Last, but not least, we would like to thank our families and friends, who inspired and encouraged us throughout and demonstrated a high level of patience during our preoccupation in putting this text together.
In particular, we would like to thank Deepa Andleigh and Bhavna Thakrar for their support and understanding, and Vaibhav, Vipur, Raj, Jay, Meera, and Karishma for their patience through two years of lost holidays and weekends.
