Abstract

This book explains the techniques to store and retrieve multimedia information in multimedia storage systems. It describes the internal architecture of storage systems. Readers will be able to learn the internal architectures of multimedia storage systems. Many techniques are described with details. Examples are provided to help readers understand the techniques. By understanding these techniques, we hope that readers may also apply similar techniques in the problems that they encounter in their everyday life.
