Ralf Steinmetz and Klara Nahrstedt Multimedia Systems 13.pdf
This article is a summary of the book Multimedia Systems by Ralf Steinmetz and Klara Nahrstedt, published by Springer in 2004. The book discusses the basic characteristics of multimedia operating systems, networking and communication, and multimedia middleware systems. The book aims to provide a broad understanding of multimedia systems and applications in an integrated manner, covering topics such as quality of service, multimedia operating systems, media servers, networks, communication, group communication, synchronization, and security.
The introduction chapter defines multimedia as the use of computer-controlled integrated media to present information that is interactive, integrated, and dynamic. The chapter also introduces the concept of multimedia systems as a combination of hardware, software, data structures, and human-computer interaction that support the processing, storage, transmission, and presentation of multimedia data. The chapter also gives an overview of the structure and organization of the book.

Quality of Service
The quality of service (QoS) chapter discusses the requirements and challenges of providing QoS for multimedia applications. The chapter defines QoS as a set of measurable properties that characterize the behavior and performance of a system or a service. The chapter also introduces the QoS parameters, such as delay, jitter, bandwidth, loss rate, error rate, availability, reliability, and security. The chapter also presents the QoS models, such as best-effort, integrated services, differentiated services, and adaptive QoS. The chapter also describes the QoS mechanisms, such as admission control, resource reservation, traffic shaping, packet scheduling, error control, congestion control, and QoS monitoring.
Multimedia Operating Systems
The multimedia operating systems chapter discusses the design and implementation of operating systems that support multimedia applications. The chapter defines multimedia operating systems as operating systems that provide efficient and predictable services for multimedia data processing. The chapter also introduces the multimedia operating system components, such as process management, memory management, file system management, device management, and user interface management. The chapter also presents the multimedia operating system techniques, such as real-time scheduling algorithms, memory allocation algorithms, disk scheduling algorithms, device driver architectures, and user interface frameworks.
The media server chapter discusses the architecture and functionality of media servers that store and deliver multimedia data. The chapter defines media servers as specialized servers that provide scalable and reliable services for multimedia data storage and retrieval. The chapter also introduces the media server components, such as storage devices, network interfaces, processors, memory modules, and software modules. The chapter also presents the media server techniques, such as data placement algorithms, data replication algorithms, buffer management algorithms, streaming protocols, and caching algorithms.
The networks chapter discusses the characteristics and challenges of networks that transmit multimedia data. The chapter defines networks as interconnected systems that provide communication services for data exchange. The chapter also introduces the network components, such as nodes, links, routers, switches, and gateways. The chapter also presents the network techniques, such as network architectures, network protocols, network topologies, network routing algorithms, and network performance metrics.
The communication chapter discusses the principles and methods of communication that enable multimedia data exchange. The chapter defines communication as a process that involves sending, receiving, and interpreting messages between entities. The chapter also introduces the communication components, such as senders, receivers, messages, channels, and codes. The chapter also presents the communication techniques, such as communication models, communication modes, communication paradigms, communication protocols, and communication services.
The group communication chapter discusses the issues and solutions of group communication that support multimedia collaboration. The chapter defines group communication as a form of communication that involves multiple senders and receivers who share a common goal or interest. The chapter also introduces the group communication components, such as group members, group identifiers, group messages, group channels, and group policies. The chapter also presents the group communication techniques, such as group formation algorithms, group coordination algorithms, group synchronization algorithms, group multicast protocols, and group security mechanisms.
The synchronization chapter discusses the concepts and techniques of synchronization that ensure temporal consistency of multimedia data. The chapter defines synchronization as a process that establishes and maintains the temporal relationships among multimedia data elements. The chapter also introduces the synchronization components, such as synchronization objects, synchronization constraints, synchronization clocks, synchronization events, and synchronization actions. The chapter also presents the synchronization techniques, such as synchronization models, synchronization methods, synchronization algorithms, synchronization protocols, and synchronization services.
