Peer-to-Peer Video Streaming describes novel solutions to enhance video quality, increase robustness to errors, and reduce end-to-end latency in video streaming systems. This book will be of use to both academics and professionals as it presents thorough coverage and solutions for current issues with Video Streaming and Peer-to-Peer architectures.Key Features: Provides overview of today’s state-of-the art video streaming technology; Presents adaptive video coding and streaming techniques for performance enhancement of conventional client-server systems and P2P multicast; Focus on throughput-limited environments where congestion often hampers interactivity and fast response times; Results derived from experiments carried out over large-scale simulated peer networks; Detailed appendix incorporates various additional experiments.

This book provides a comprehensive, modern approach to signals and systems, concentrating on those aspects that are most relevant for applications such as communication systems and signal processing. Emphasis is placed on building the reader's intuition and problem-solving ability, rather than formal theorems and proofs."The coverage of the book is comprehensive, providing a broad overview, using a whole host of exercises. The wealth of the worked examples and problems complemented by solutions is particularly attractive. The level of mathematics is not too daunting for the good average student and the authors do their utmost to mitigate the difficulties, skilfully using worked examples."Prof. Lajos Hanzo, University of Southamptonauthor of Mobile Radio Communications and Single-and Multi-carrier QAMCheck out the companion Website for 'Systool' simulation software using Java applets to animate many of the key examples and exercises from the book.

This volume presents a comprehensive description of a technique in video coding and transmission. The work presented in the book has had a very strong impact on video coding standards and should be of interest to practicing engineers and researchers as well as academics. The multi-frame technique and the Lagrangian coder control have been adopted by the ITU-T as an integral part of the well known H.263 standard and are were adopted in the ongoing H.26L project of the ITU-T Video Coding Experts Group.

Watermarking has become a mature discipline with a foundation in both signal processing and information theory. This book addresses watermarking problems in terms of second-generation insights. It provides a complete overview of the most important results on capacity and security. The Costa scheme, and in particular a simpler version of it, the Scalar Costa scheme, is studied in great detail. An important result of this book is that it is possible to approach the Shannon limit within a few decibels in a practical system. These results are verified on real-world data, not only the classical category of images, but also on chemical structure sets. The text aims to act as a tool for both academic and professional researchers working in the areas of multimedia security, information embedding, and communication. Theory and practice are linked, particularly in the area of multi-user communication. Inspired by the work of Moulin and O'Sullivan, it also addresses security aspects by studying AGWN attacks in terms of game theory.

Video Coding with Superimposed Motion-Compensated Signals: Applications to H.264 and Beyond captures recent advances in motion compensation for efficient video compression. This book investigates linearly combined motion compensated signals, and generalizes the well known superposition for bidirectional prediction in B-pictures. The number of superimposed signals and the reference picture selection are important aspects of discussion. The application oriented part of the book employs the concept to ITU-T Recommendation H.263, and continues with the improvements by superimposed motion-compensated signals for the EMERGING STANDARDS ITU-T Recommendation H.264 & ISO/IEC MPEG-4 part 10. In addition, Video Coding with Superimposed Motion-Compensated Signals: Applications to H.264 and Beyond discusses a new approach for wavelet-based video coding. This technology is currently being investigated by MPEG, to develop a new video compression standard for the mid-term future. The theoretical part of Video Coding with Superimposed Motion-Compensated Signals: Applications to H.264 and Beyond provides a deeper understanding of the underlying principles of superimposed motion-compensated signals.

This book deals with digital watermarking, which is defined by the authors of this book as the art of hiding auxiliary information in digital data in a secure, robust and imperceptible fashion. Digital watermarking as a topic has a long history, but before 1995 publications in scientific literature were almost absent. From 1995 onwards however the number of publications on watermarking has been steadily increasing. Today a number of workshops and conferences on this topic exist; also a number of scientific journals on watermarking have been published. This renewed scientific interest in digital watermarking has led very quickly to industrial interest, as well. In 1996 the Copy Protection Technical Working Group, a voluntary consortium consisting of the movie industry, the IT industry and the consumer electronics industry, issued a call for watermarking technologies for the purpose of copy protection of DVD-Video. A few years later the Secure Digital Music Initiative issued a similar call, in this case focusing on copy protection of digital music. These two efforts have been only partially successful: copy protection based on digital watermarking is not (yet) implemented on a large scale in any type of consumer device. This current "failure" of watermarking, to live up to its expectations, finds its cause in a large number of reasons, ranging from legal considerations and system aspects to the relative immaturity of watermarking as a technology.

Veranstaltung angeboten. Der Stoff dieses Buches wird dabei in etwa 50 Vorlesungs­ und 25 Übungsstunden vollständig durchgearbeitet. Die Grundzüge der Ingenieurma­ thematik (Differential- und Integralrechnung, lineare Algebra) und Grundkenntnisse elektrischer Netzwerke werden dabei vorausgesetzt. Wenn diese Kenntnisse schon früh genug erlernt werden, ist der Stoff auch für eine Präsentation im 3. oder 4. Semester ge­ eignet. Kenntnisse der komplexen Funktionentheorie und der Wahrscheinlichkeitslehre werden häufig ebenfalls in einem ingenieurwissenschaftlichen Grundstudium erworben, sie sind hilfreich, werden aber nicht vorausgesetzt. Das Buch ist auch zum Selbststu­ dium geeignet. Bei ganztägiger, konzentrierter Arbeit sind zur Erarbeitung des Stoffes etwa 4 -6 Wochen zu veranschlagen. Die Präsentation beginnt mit den kontinuierlichen Signalen und Systemen. Anders als in manchen anderen Büchern, in denen erst ausführlich Beschreibungsformen für Signale eingeführt werden und viel später Systeme, behandeln wir Signale und Syste­ me parallel. Die Zweckmäßigkeit der Beschreibung von Signalen durch ihre Laplace­ oder Fourier-Transformierten ergibt sich nämlich erst aus den Eigenschaften von li­ nearen, zeitinvarianten Systemen. In der Präsentation betonen wir das anschauliche Konzept von Eigenfunktionen, die von Systemen in ihrer Form nicht verändert werden. Zur korrekten Berücksichtigung von Anfangsbedingungen verwenden wir die Zustands­ raumsbeschreibung, aus der elegant die Überlagerung eines externen und eines internen Anteils der Systemantwort folgt. Nach der Behandlung der Abtastung werden zeitdis­ krete Signale und Systeme eingeführt und die für den kontinuierlichen Fall bekannten Konzepte erweitert. Im weiteren Verlauf werden danndiskrete und kontinuierliche Si­ gnale und Systeme gemeinsam behandelt. Den Abschluß bildet die heute so wichtige Behandlung von Zufallssignalen.

Die Analyse und der Entwurf von Systemen mit Hilfe geeigneter mathematischer Werkzeuge ist für den Elektroingenieur außerordentlich wichtig. Entsprechend ist die Systemtheorie ein Kerngebiet der modernen Elektrotechnik, auf dem eine große Zahl von Teildisziplinen aufbaut und deren sichere Beherrschung für den erfolgrei­ chen Zugang zu Spezialgebieten Voraussetzung ist. Eine Einführung in die Systemtheorie beginnt sinnvoll mit der einfachsten Ab­ straktion, den linearen, zeitinvarianten Systemen. Anwendungen dieser Systeme sind allgegenwärtig, und ihre Theorie besitzt heute eine große Reife und Eleganz. Bei Studierenden, die sich zum ersten Mal mit der Theorie linearer, zeitinvarianter Systeme auseinandersetzen, gilt das Fach leider oft als schwierig, und ist, wenn sich der erwünschte und verdiente Lernerfolg nicht einstellen will, vielleicht sogar rich­ tiggehend unbeliebt. Das mag mit der Abstraktheit des Stoffes zusammenhängen und mit seiner deduktiven und unanschaulichen Präsentation in manchen Vorle­ sungen. Da sich ein Mißerfolg in den Grundlagen der Systemtheorie aber für viele Vertiefungsfächer verheerend auswirkend würde, darf er keinesfalls hingenommen werden. Wir haben das vorliegende Buch als eine leicht zugängliche Einführung für Studierende der Elektrotechnik geschrieben. Die Inhalte, die präsentiert werden, sind nicht neu. Sie wurden schon oft in anderen Bücher aufgeschrieben. Neu ist die Art der Präsentation des Stoffes. Unsere Absicht ist es, die abstrakten Konzepte und Zusammenhänge der Systemtheorie durch kleine anschauliche Schritte der Erklärung so einfach darzustellen, daß das Lernen leicht fällt und Spaß macht. Ob das uns das gelungen ist, können natürlich nur Sie, liebe Leserin und lieber Leser, entscheiden.
