A multimedia system needs a mechanism to communicate with its environment, the Internet, clients, and applications. MPEG-7 provides a standard metadata format for global communication, but lacks the framework to let the various players in a system interact. MPEG-21 closes this gap by establishing an infrastructure for a distributed multimedia framework, allowing for the creation, modification, viewing, and communication of digital items among all participants within an MPEG-21 agreement.
Now you have a guide that examines the structure and potential usage of these emerging standards. Distributed Multimedia Database Technologies Supported by MPEG-7 and MPEG-21 describesthe technologies, concepts, and tools of distributed, content-based multimedia systems. It focuses on the practical uses of the technologies of MPEG and SQL/MM in these components, and on the interoperability among them (for data exchange, transactions, interaction, etc.). This book demonstrates an open distributed multimedia framework that enables these components to cooperate in a working environment, delivering rich multimedia access in an increasingly mobile world.
