Optical Switching: Networking and Computing for Multimedia Systems

By, Mohsen Guizani, Abdella Battou

This volume reveals the latest research on commercial systems with up to 160 OC-48 channels, optical ATM switch architectures, optical multiprotocol lambda and label switching, synchronous optical networks and digital hierarchy, and the Internet Protocol layer. The text includes recent developments in the routing efficiency of multihop optical networks supported by wavelength division multiplexing (WDM) with limited wavelength conversion. It also explores different routing techniques in WDM networks for virtual topology mapping, wavelength routing and assignment, dynamic routing, QoS provisions, and multicasting. The book examines challenges facing carriers and service providers in expanding optical networking capabilities for the next generation Internet.  

Multimedia Wireless Networks: Technologies, Standards, and QoS

By, Aura Ganz, Zvi Ganz, Kitti Wongthavarawat

From entertainment to telephony, emerging wireless systems will make possible a newgeneration of wireless multimedia applications. To satisfy users, network designers anddevelopers must integrate end-to-end Quality of Service (QoS) support throughout all theirunderlying networks: WANs, WLANs, WPANs, and "last-mile" WLL or satellite distributionsystems. However, wireless network standards typically focus on signaling, leaving crucial QoSissues to implementers. Multimedia Wireless Networks is the first book to help networkprofessionals systematically address QoS in today's most important wireless networks-andtomorrow's.l Why users' wireless multimedia performance requirements will require extensive QoSsupportl The fundamentals of QoS - and how they drive network designl WLAN standards from the multimedia network designer's viewpoint: IEEE 802.11,HiperLAN, and HomeRFl Wireless MANs: introducing the new 802.16 WirelessMAN standardl Integrating QoS into IEEE 802.15 and Bluetooth wireless personal area networksl QoS in current and emerging cellular and satellite networks"  

Signal Processing for Telecommunications and Multimedia

By, Tadeusz A. Wysocki, Bahram Honary, Beata J. Wysocki

The unprecedented growth in the range of multimedia services offered these days by modern telecommunication systems has been made possible only because of the advancements in signal processing technologies and algorithms. In the area of telecommunications, application of signal processing allows for new generations of systems to achieve performance close to theoretical limits, while in the area of multimedia, signal processing the underlying technology making possible realization of such applications that not so long ago were considered just a science fiction or were not even dreamed about. We all learnt to adopt those achievements very quickly, but often the research enabling their introduction takes many years and a lot of efforts. This book presents a group of invited contributions, some of which have been based on the papers presented at the International Symposium on DSP for Communication Systems held in Coolangatta on the Gold Coast, Australia, in December 2003. Part 1 of the book deals with applications of signal processing to transform what we hear or see to the form that is most suitable for transmission or storage for a future retrieval. The first three chapters in this part are devoted to processing of speech and other audio signals. The next two chapters consider image coding and compression, while the last chapter of this part describes classification of video sequences in the MPEG domain.

Multimedia Applications of the Wavelet Transform

By, Schremmer C.K.

In the context of the teleteaching project Virtuelle Hochschule Oberrhein, i.e.. Virtual University of the Upper Rhine Valley (VIROR). which aims to establish a semi-virtual university, many lectures and seminars were transmitted between remote locations. We thus encountered the problem of scalability of a video stream for different access bandwidths in the Internet. A substantial contribution of this dissertation is the introduction of the wavelet transform into hierarchical video coding and the recommendation of parameter settings based on empirical surveys. Furthermore, a prototype implementation of a hierarchical client-server video program proves the principal feasibility of a wavelet-based, nearly arbitrarily scalable application.Mathematical transformations of digital signals constitute a commonly underestimated problem for students in their first semesters of study. Motivated by the VIROR project, we spent a considerable amount of time and effort on the exploration of approaches to enhance mathematical topics with multimedia; both the technical design and the didactic integration into the curriculum are discussed. In a large field trial on traditional teaching versus multimedia-enhanced teaching, in which the students were assigned to different learning settings, not only the motivation, but the objective knowledge gained by the students was measured. This allows us to objectively rate positive the efficiency of the teaching modules developed in the scope of this dissertation. 

Wireless Communication Technologies: New Multimedia Systems

By, Morinaga N. (ed.), Kohno R. (ed.), Sampei S. (ed.)

Wireless Communication Technologies: New Multimedia Systems is based on a selection of the best papers presented at the recent International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC '99). All of the papers have been extended into full chapters, critiqued, and edited into a unified and structured book.Contributions to this volume are by the leading specialist from their respective fields. The topics represent the newest ideas and research involving wireless multimedia systems and wireless technologies. Part I focuses on key developments and technologies and includes coverage of wireless channel modeling, space-time coding, coding for wireless networks, OFDM, software radio, and spatial and temporal communication theory. Chapters in Part II address many of the new wireless systems currently being standardized; such as, intelligent transport systems, wireless internet, digital

Multimedia Communications: Directions and Innovations

By, Gibson J.D. (ed.)

This book is a collection of invited chapters on multimedia communications contributed by experts in the field. We use the term multimedia communications to encompass the delivery of multiple media content such as text, graphics, voice, video, still images, and audio over communications networks to users. Note that several of these media types may be part of a particular interaction between (or among) users, and thus we are not simply considering networks that support different traffic types. We are specifically interested in applications that incorporate multiple media types to deliver the desired information. Example applications of interest include two-way, multipoint videoconferencing and one-way streaming of video and audio in conjunction with text or graphical data.The topics covered in the book were carefully selected to provide critical background material on multimedia communications and to expose the reader to key aspects of the hottest areas in the field.
